crDroid is built on top of LineageOS, and is designed to increase performance and reliability over stock Android for your device, while also attempting to bring you many of the best features in existence today.
Features
A quick glossary and primer on slots for A/B devices (like ours):
Spoiler: Show/Hide
- "Clean flash": Removing device protection & clearing user settings before installing a bootable system install zip (usually by either wiping or formatting data, see below).
- "Dirty flash": Flashing a ROM zip (usually upgrading to new version, sometimes just re-flashing the existing one) without wiping data or anything first.
- "Wipe data": Synonymous with "factory reset", accomplished from TWRP recovery by selecting "Wipe", then performing the "Slide to factory reset". Clears user data without erasing any partitions, removing encryption, or deleting contents of internal storage.
- "Format data": Formats the data partition itself, resets all file-based encryption keys, loses all contents of internal storage, and in fact deletes all "user 0" directories (this has some implications for internal storage before & after first boot).
- "User 0" directories are a series of directories that store userdata for the primary user, "Owner", and get created in various places throughout the filesystem on first system boot if they don't exist already. Anything you copy to "internal storage" while booted in recovery after "formatting data" will actually be copied to /data/media/ instead of /data/media/0/, and will become invisible to regular file browsing after first boot once the system has created /data/media/0, since the system will prefer to use that path for internal storage from then on (so you'll need a root file browser to delete things from /data/media, or just ADB sideload things instead of copying after formatting but before booting).
- "OTA package": Originally an abbreviation for "over the air", referring to how a software update could be delivered (as opposed to having to take your phone to a carrier's store for a firmware update via serial/USB connection). The common usage in Android circles is any installation zip file that actually includes a bootable system.
- Some partitions are duplicated (system, vendor, boot, and probably a couple others, but not data) and have a "slot A" & "slot B" copy.
- "Slot A" and "slot B" are absolute designations, but most installer zip scripts use the relative designations: "active" and "inactive". Whichever slot you're booted from currently is "active", and the other one is "inactive".
- Installing a zip file that's flagged as being an OTA package will 1) install the contents to the "inactive" slot, and then 2) flag the bootloader to switch which slot is considered "active" (and booted from) and "inactive" upon next reboot.
- The OxygenOS full OTA zip files and all custom ROM installer zip files are considered "OTA packages" and will trigger a slot switch on next boot after installation.
- You can install multiple OTA zip packages one after the other without rebooting in TWRP; they will all get installed into the correct partitions in the "inactive" slot, one on top of the other, and then it will swap active & inactive upon reboot.
- We don't use what are called "delta" updates, which can patch existing partitions by block or by file; we use full filesystem images. So for us, OTA zip packages are really just a bunch of partition filesystem image files all wrapped up into a "payload.bin" with some extra instructions & metadata/checksums, so when you flash a ROM, it overwrites entire partitions at a time instead of individual files or filesystem blocks within that partition. So if you've changed something in a partition like system that gets written as part of flashing an OTA zip, all your changes are gone. The only thing in the system partition afterward will be what was in the system.img that was included in the ROM zip payload.
- The partitions that crDroid, LineageOS, and most custom ROMs for OnePlus 6 & 6T install to when flashing are boot (contains recovery & kernel), dtbo, system, and vbmeta. Some ROMs (like Syberia) build the vendor partition from source instead of just trying to work with the existing OEM vendor partition, so they flash that one too when installing. So you definitely need to flash stock vendor before switching from Syberia or another source-built vendor ROM to one like Lineage or crDroid that uses prebuilt.
- "Prebuilt vendor" vs. "source-built" vendor partitions: when first trying to get a custom ROM working on a new device now that we have separate system & vendor partitions & Google's "Project Treble" is a thing, you'll often just leave the contents of the vendor partition alone, because that's where all the proprietary or device-specific stuff lives (manufacturer specific hardware drivers & interfaces, any DRM libraries, custom frameworks & selinux policies for talking to them), and you make a compatibility map of what framework versions you're compiling against in system and what vendor version they're compatible with or supersede or you overlay updated things that should replace stuff in the vendor partition and keep it in system_ext instead. But you're also limited in that if there are some things in vendor, you CAN'T work around it from the ROM side (like, OnePlus Camera working correctly). So often, once the basics are functioning, the goal is to move to building the contents of the vendor partition from source, because you then have the freedom to fix problems with sepolicy, library/framework mismatches, etc. and make things work with the custom ROM instead of only working with the OEM's flavor of Android, and you can still copy individual pre-compiled files from the stock vendor filesystem image if needed (like if there's no open-source equivalent for some driver). Unfortunately, OnePlus SDM845 (enchilada & fajita, the OP6 & OP6T) never got a proper source-built vendor bringup by the LineageOS team (upon which crDroid is based). And while Syberia has had source built vendor in Android 11 (possibly 10?), it was only done for enchilada and NOT fajita, it's not trivial to unroll & commonize what they've done to apply to other ROMs, and some of the proprietary files they keep are imported from other similar devices/similar chipsets rather than source-built (presumably because the OnePlus ones are modified in a weird way that the open-source components can't hook into, but still not ideal). So for fixing a lot of the issues we still face with lack of things working quite right, or hardware features not available in custom ROMs (especially compared to newer OnePlus devices like the 7, 8, or 9 series), we're kinda stuck, because you can't just implement it against the stock prebuilt vendor.
- "Updating firmware" simply means we're flashing updated contents from the manufacturer into all the OTHER partitions besides the ones that the ROM OTA zip touches. There are another dozen or more of those, besides system & boot, that the full OxygenOS OTA zip would normally write to when you install it. The contents of the system partition in custom ROMs for our device are generally built against a particular version of OxygenOS (mostly the contents of the OEM vendor partition).
Prerequisites:
- Make sure your bootloader is unlocked (and don't plan on relocking it ffs).
- Make sure you have a reasonably-current, working installation of android platform tools (adb & fastboot command line binaries & necessary drivers) on your computer, with a known-good USB cable (see links in post #2).
- Make sure you've downloaded the most recent full Android 10 OxygenOS OTA installer zip (10.3.12), crDroid zip, matching crDroid boot.img, official TWRP 3.5.2_9-0 installer zip and bootable img, and whatever Magisk/GApps/microG installation packages you want to use to your computer (see links in post #2).
- Make sure you've backed up whatever data you want to keep to somewhere that's not on your phone; for a new install, we're going to format the data partition and you're going to lose everything from internal storage.
Let's get started!
Updating firmware (if already on crDroid):
- Reboot to bootloader (with no USB cable connected).
- Open a terminal on your computer, and run `fastboot flash boot path/to/boot.img`, substituting in the path & filename for the current crDroid boot.img that you downloaded as part of the prerequisites.
- Reboot to bootloader again (actually loads new bootloader that you just flashed).
- Use Vol +/- buttons to select "Recovery mode" and press Pwr button to boot into the built-in TWRP recovery. The device's internal storage should now be available for read/write on the computer via MTP.
- Copy the official OxygenOS 10.3.12 full OTA zip & latest crDroid zip into the device's internal storage, then choose "Install", select the current crDroid zip, choose "Add more zips", and crDroid installer zip, then swipe to confirm flash. No TWRP zip required, since it's built in to the boot.img that gets installed.
- Reboot recovery, then choose "Install", and select the OOS zip, then select "Add more zips" and choose the crDroid zip, and swipe to confirm flash again.
- Reboot recovery, and re-flash magisk/gapps if needed.
- Wipe dalvik.
- Reboot system.
First time installing crDroid to your OP6T, coming from stock OxygenOS or another ROM (will also update firmware while we're at it):
- Reboot to bootloader, then `fastboot boot path/to/twrp.img` to start up into TWRP recovery.
- Mount System partition read-write, use file manager to delete the /system/addons.d/ directory if it exists, unmount System.
- Choose Wipe > Format data, type "yes" and hit enter to nuke everything in the data partition and clear encryption.
- Choose Advanced > ADB sideload (don't worry about selecting cache/dalvik wipe options yet) and then on the computer, do `adb sideload path/to/OxygenOSOTA.zip` to flash the OxygenOS 10.3.12 full OTA installation zip & make sure you're on the latest Android 10 firmware.
- Go get a drink, this'll be a bit.
- When that's done, hit "back" in TWRP and start ADB sideload again, and this time send the crDroid installation zip (includes TWRP built-in, so don't need separate zip for that at this point).
- Reboot to recovery (this will switch the active slot to use the system partition you just installed those zip files into).
- Wipe data (Wipe > "Slide to factory reset" in TWRP).
- That was so much fun, let's do it again! ADB sideload OxygenOS full OTA zip.
- ADB sideload crDroid zip.
- Reboot to recovery (switches slots again, now we have latest OxygenOS firmware plus crDroid populated in both sets of partitions and won't have to do that again).
- Flash Magisk (if desired).
- Flash GApps or microG package (if desired).
- Wipe dalvik.
- If you copied anything to internal storage instead of flashing it via ADB sideload, delete it now before first boot.
- Reboot system.
- Go through setup wizard.
- Reboot system (for reasons I don't comprehend, it never shows "OnePlus Settings" in the Settings app top level menu on a fresh install until after rebooting once).
- It's gonna harass you to finish setup, go ahead and customize everything to your heart's content.
Updating crDroid from TWRP (preferred):
You don't need to remove device protection; it works fine with PIN. Be sure you have a PIN set, or have looked up whatever that arcane chart of pattern > numeric incantations in case of pattern unlock. It's awful.
- Boot into TWRP recovery.
- Choose install, then select OOS firmware OTA (if needed), then choose select additional zips, then select crDroid.zip, slide to confirm flash.
- Reboot recovery.
- Choose install, then select Magisk zip (if using), select additional zips, choose GApps/microG (if using), slide to confirm flash.
- Please keep off of the grass, shine your shoes, wipe your... dalvik.
- Reboot system.
Updating crDroid from Updater app:
Warning: I don't remember if crDroid 6 even *has* the built-in Updater app function or not, or how well it handles addon.d survival scripts. Use with caution.
- Install update in built-in Updater app (Settings > System > Updater), do NOT reboot yet.
- Go to Magisk app home, click "Install" next to Magisk, and choose the "Install to Inactive Slot (After OTA)" method.
- For GApps/microG: If you use GApps/microG that needs to be re-flashed to /system (as opposed to magisk module GApps/microG), reboot *recovery* at this point, mount the system partition in TWRP, and dig around with the File Manager in system/priv-app/ & system/product/priv-app/ to make sure that everything you expect was copied over to the now-currently-active slot, and if need be re-flash your installer zip, or else your world will be pain when you boot normally. Yes, I expect you to know what your preferred package installs & to keep the zip handy.
- NOW you can reboot to system.
Reporting bugs:
I'm a parent of three young kids whose industry disappeared in the pandemic and is now full-time house husband & parent-in-charge while my wife is teaching full-time, I'm trying to save my small live-event-turned-streaming-studio company in my spare time. I'm doing in-home caregiving for a family member overnight one day a week. This is the back-up spare-spare-time hobby. I'm not a software developer nor do I know any programming languages, I just wanted a ROM with signature spoofing support and more customization than the unofficial microg-compatible LineageOS builds. So if there are bugs or feature requests, I go over to the crDroid dev chat and ask if someone has time to hold my hand & help. Don't make me get yelled for annoying them, mmkay? That said...
- Logs/screenshots/recordings or it didn't happen. Syslog (free, open source, available on Play store and F-droid) is your friend.
- I try to keep an organized notebook of roadmap, feature reqeusts, bug reports, etc. I won't always be able to fix it, but I'll at least look and do my best to ask the actual devs.
- I don't sign into XDA much, so if I haven't said anything, check out the Telegram group. Lots of helpful folks there.
- Please keep your questions in this thread instead of PMing me with them directly, so that the entire class can benefit from the discussion and you can find out if it's just you or if this is a widespread issue.
It's your device to use the way you want of course, and I use Magisk & microG and like to tweak things myself. But don't expect much support if you:
- didn't do a clean flash.
- aren't using the built-in kernel.
- are using extensive modifications (besides Magisk) like Xposed/Riru, Dolby Atmos, Viper4A, etc.
- immediately start using "finalize.zip" or flashing migrate restore zips instead of following the actual instructions.
- are running decrypted.

- Kernel: https://github.com/crdroidandroid/android_kernel_oneplus_sdm845/tree/10.0

Notes:
- Yes it supports package signature spoofing permission for microG compatibility out of the box (but will work without ANY GApps/microG implementation installed as well).
- Aux camera doesn't work correctly due to framework issues beyond my control/comprehension. So, still no portrait mode in OnePlusCamera in cr6. But 60fps video recording in OOSCam works great; huzzah!
- Doesn't pass safetynet out of the box, despite many tests with different fingerprints/props. Just use Magisk & enable the Zygisk DenyList & kdrag0n's "safetynet-fix" module and be happy. If your bank's app doesn't work, switch to a local credit union and stop feeding the bougie bankers. Smash capitalism!
- Maintainer does not use GApps, so cannot answer questions about which packages work best from firsthand experience. In general, go with the smallest package you can and then install other Google apps from the Play Store. Please note that if you replace the stock dialer with Google Dialer, you may lose access to the Phone Info menu (*#*#4636#*#*) until you install another dialer. For recommendations, see https://wiki.lineageos.org/gapps.
- Requires OOS 10.3.12 OOS firmware.
- Includes built-in TWRP, pulled from official 3.5.2_9-0 ramdisk, works well.
- Tested against latest Magisk canary (with zygisk instead of magiskhide), works well.
- No there won't be official builds with inline GApps; please don't ask.
crDroid 6.27 - February 2022 ASB release notes/known issues:
Changelog since v6.23 release:
- Merged Android Security Bulletins through February 2022 from upstream.
- Whatever changed upstream in the ROM proper (not likely much; they want to freeze it besides security updates).
- Reimplemented DeviceSettings based on crDroid 7 version (no more greyed-out things that don't actually work in Android 10).
- Backported updated display panel handling in device tree and kernel to match crDroid 7 (panel color modes are in LiveDisplay now). FOD on fajita is still kinda crap with OOS 10 firmware, but oh well.
- Little more tidying/tightening in device tree & kernel for moving to maintenance-only releases.
- Imported current wireguard VPN kernel-mode driver.
Known issues:
Fajita-specific:
- FOD seems to work kinda, um, crap compared to how it is on OOS 11 firmware. Not much I can do about that, unfortunately.
Common:
- Some screen-off gestures may not work, due to limitations beyond my control; don't use those gestures. Sorry.
- You tell me! With logs!
Other stuff:
- At this point, any little feature bugs will be considered "can't fix/won't fix"; I can't keep working on this one, I'm going to try to only do security-update-only releases of crDroid v6.
- Where do bad rainbows go? Prism. It's a light sentence.
Helpful links:
Download ROM
TWRP (use old official v3.5.2_9-0)
(TWRP is built-in to the crDroid 6 zip, but you might need the img or standalone installer zip in order to get to that point)
Magisk (use latest)
OxygenOS 10.3.12 Full OTA
MSMTool (oh now you're in trouble - use latest unless you have a good reason to intentionally downgrade)

first to test it...just flashing it...hope its better than every 10 rom that are available currently!!!!

It's early in development. They are all going to have that 'new car smell'. Lower expectations. Bare bones but stable is a milestone.

Hello everyone, firstly thanks Dev and team for your efforts developing CRDroid, question... where can I download android 10? Because the website only shows Pie downloads and 10 only says soon. Thanks guys and have a good day.

go to pie downloads, there you will find a 6.x folder to

All downloaded ready to flash when I get home
Thanks for the rom dev?

Let the game begin, I'm almost done restoring everything, clean flash including internal storage. It booted fine, no issues whatsoever, everything is running nice and smooth, wifi, wifi calling, Bluetooth, FP. Thanks Dev. and team.

So when I click on "wallpapers" on home screen, it says app isn't installed. So, is there any fix?

Yes there is, that's the reason I took that screenshot. Happy flashing bud.

Just superb work.. I am casual user.. Plays lot of games, YouTube and online streaming.. Seems pretty solid so far..

With all due respect to other Devs. this is the one I like the most, lots of customizations compared to other android 10 roms, give a try I beat you won't be disappointed. This is my personal opinion. Happy flashing bud.

Yep just opinions is all I ask for, I don't care much for hierarchy, so not necessarily looking for one thing better over another, I just know 10's in the early stages and I'm not even thinking about jumping over yet, I just like to hear what people think.

Prerequisites:
- Make sure your bootloader is unlocked (and don't plan on relocking it ffs).
- Make sure you have a reasonably-current, working installation of android platform tools (adb & fastboot command line binaries & necessary drivers) on your computer, with a known-good USB cable (see links in post #2).
- Make sure you've downloaded the most recent full Android 10 OxygenOS OTA installer zip (10.3.12), crDroid zip, matching crDroid boot.img, official TWRP 3.5.2_9-0 installer zip and bootable img, and whatever Magisk/GApps/microG installation packages you want to use to your computer (see links in post #2).

- Go to Magisk app home, click "Install" next to Magisk, and choose the "Install to Inactive Slot (After OTA)" method.
- For GApps/microG: If you use GApps/microG that needs to be re-flashed to /system (as opposed to magisk module GApps/microG), reboot *recovery* at this point, mount the system partition in TWRP, and dig around with the File Manager in system/priv-app/ & system/product/priv-app/ to make sure that everything you expect was copied over to the now-currently-active slot, and if need be re-flash your installer zip, or else your world will be pain when you boot normally. Yes, I expect you to know what your preferred package installs & to keep the zip handy.
- NOW you can reboot to system.
Reporting bugs:
I'm a parent of three young kids whose industry disappeared in the pandemic and is now full-time house husband & parent-in-charge while my wife is teaching full-time, I'm trying to save my small live-event-turned-streaming-studio company in my spare time. I'm doing in-home caregiving for a family member overnight one day a week. This is the back-up spare-spare-time hobby. I'm not a software developer nor do I know any programming languages, I just wanted a ROM with signature spoofing support and more customization than the unofficial microg-compatible LineageOS builds. So if there are bugs or feature requests, I go over to the crDroid dev chat and ask if someone has time to hold my hand & help. Don't make me get yelled for annoying them, mmkay? That said...
- Logs/screenshots/recordings or it didn't happen. Syslog (free, open source, available on Play store and F-droid) is your friend.
- I try to keep an organized notebook of roadmap, feature reqeusts, bug reports, etc. I won't always be able to fix it, but I'll at least look and do my best to ask the actual devs.
- I don't sign into XDA much, so if I haven't said anything, check out the Telegram group. Lots of helpful folks there.
- Please keep your questions in this thread instead of PMing me with them directly, so that the entire class can benefit from the discussion and you can find out if it's just you or if this is a widespread issue.
It's your device to use the way you want of course, and I use Magisk & microG and like to tweak things myself. But don't expect much support if you:
- didn't do a clean flash.
- aren't using the built-in kernel.
- are using extensive modifications (besides Magisk) like Xposed/Riru, Dolby Atmos, Viper4A, etc.
- immediately start using "finalize.zip" or flashing migrate restore zips instead of following the actual instructions.
- are running decrypted.

Notes:
- Yes it supports package signature spoofing permission for microG compatibility out of the box (but will work without ANY GApps/microG implementation installed as well).
- Aux camera doesn't work correctly due to framework issues beyond my control/comprehension. So, still no portrait mode in OnePlusCamera in cr6. But 60fps video recording in OOSCam works great; huzzah!
- Doesn't pass safetynet out of the box, despite many tests with different fingerprints/props. Just use Magisk & enable the Zygisk DenyList & kdrag0n's "safetynet-fix" module and be happy. If your bank's app doesn't work, switch to a local credit union and stop feeding the bougie bankers. Smash capitalism!
- Maintainer does not use GApps, so cannot answer questions about which packages work best from firsthand experience. In general, go with the smallest package you can and then install other Google apps from the Play Store. Please note that if you replace the stock dialer with Google Dialer, you may lose access to the Phone Info menu (*#*#4636#*#*) until you install another dialer. For recommendations, see https://wiki.lineageos.org/gapps.
- Requires OOS 10.3.12 OOS firmware.
- Includes built-in TWRP, pulled from official 3.5.2_9-0 ramdisk, works well.
- Tested against latest Magisk canary (with zygisk instead of magiskhide), works well.
- No there won't be official builds with inline GApps; please don't ask.
crDroid 6.27 - February 2022 ASB release notes/known issues:
Changelog since v6.23 release:
- Merged Android Security Bulletins through February 2022 from upstream.
- Whatever changed upstream in the ROM proper (not likely much; they want to freeze it besides security updates).
- Reimplemented DeviceSettings based on crDroid 7 version (no more greyed-out things that don't actually work in Android 10).
- Backported updated display panel handling in device tree and kernel to match crDroid 7 (panel color modes are in LiveDisplay now). FOD on fajita is still kinda crap with OOS 10 firmware, but oh well.
- Little more tidying/tightening in device tree & kernel for moving to maintenance-only releases.
- Imported current wireguard VPN kernel-mode driver.
Known issues:
- Some screen-off gestures may not work, due to limitations beyond my control; don't use those gestures. Sorry.
- You tell me! With logs!
Other stuff:
- At this point, any little feature bugs will be considered "can't fix/won't fix"; I can't keep working on this one, I'm going to try to only do security-update-only releases of crDroid v6.
- Where do bad rainbows go? Prism. It's a light sentence.
Helpful links:
Download ROM
TWRP (use old official v3.5.2_9-0)
(TWRP is built-in to the crDroid 6 zip, but you might need the img or standalone installer zip in order to get to that point)
Magisk (use latest)
OxygenOS 10.3.12 Full OTA
MSMTool (oh now you're in trouble - use latest unless you have a good reason to intentionally downgrade)

Thanks dev. This is a great ROM
When you say latest fw, you are talking about OOS Pie or H2OS Q?

Any bugs or something not working?
Will try this weekend.

Thank you dev

Hello, I flashed rom yesterday.
I've got 1 issue. Fingerprint unlock doesn't work. I mean fingerprint sensor works because I can set up a fingerprint. But when phone is locked (screen on or off) I can't unlock it.
Maybe this is Gapps related? (I used Nano beta from october). Not rooted
Rom is fast and responsive. No other bug/ lag or freezes so far.
If anyone can help me with fingerprint unlock it would be much appreciated.
Have a nice day.

I assume you used the 'Green Box' link in Sourceforge? That always trips people up. That link is the latest ROM across all crDroid devices. (Currently the OP5 'Cheeseburger') Or next time actually read the file name before flashing.
Ignore that Green Box. Just pretend it doesn't exist. Use the links underneath to get the Enchilada downloads.

does it supports signature spoofing?

just tried moving from havoc 2.9 (pie) to crd6 (q), but unfortunately at this point no twrp can handle Q OOS flashing (to bring firmware to up to Q levels), latest available twrp is Mauronofrio's 3.3.1.4 so if anyone succeeds in flashing stock followed by CrD6 on a later/another twrp, would love to hear the success story...
for now, someone suggested only a local upgrade route within ota, but you end up without a functioning twrp environment which is probably too much hassle for most, so we will wait on the sidelines for a bit longer.
hope this helps!

What the latest fw is required pie or Q beta 1?

Can be flashe with oos 10 base ?

[Guide]Installing Lineage

Installing Lineage​
Few quick things.
LOS 18.1 is now official so the guide will now just be covering that.
I also want to address a common question, you can use Windows for this process. I prefer Linux, and Fastboot just works in Linux without driver issues. If you have Fastboot and ADB working in Windows already feel free to use that if you want.
Frequently asked Questions:
This looks like a lot of work, is there an easier way to install? Try the LOS Wiki Method.
Using TWRP 3.5.2_9-0​1. Start off Fresh. Install OOS using the Fastboot ROM.
Start off with a fresh install of OOS. You need the latest version of OOS 10. I typically use a the fastboot ROMs for this as it will do both slots for me at once. (Alternatively you can use TWRP and install the ZIPs and do it twice to get it on both slots, or my least favorite, the MSM Tool if you want. Doesn't matter how OOS ends up on both slots, as long as it ends up on both slots.)
I use Linux, and honestly I feel like it's easier and more reliable for fastboot and ADB so that's what I'm including here in these steps. It's easy to boot from a USB.
To create a bootable Linux flash drive you can use Unetbootin, which you can download for free here (Your other option would be to burn the ISO straight to a DVD and skip the unetbootin step):
https://unetbootin.github.io/
For Linux, I'm using Linux Mint Cinnamon, You can download for free here:
https://www.linuxmint.com/download.php
Then run unetbootin (yours will look a little different, I'm running it in Linux):
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Point it to the Linux ISO, and tell it where an empty flash drive is. It will erase everything on the flash drive. Afterwards you can load whatever you want on the flash drive. However be aware when booting Linux from this drive you can't access what is on the drive (at least not by normal methods).
After this has successfully completed, reboot the PC, and boot from the USB drive. Your PC will boot into Linux (turning off the PC and removing the USB drive will make it boot up like normal again).
Next we need to install fastboot and adb. You need to open up the "start menu" and open the "synaptic package manager". You can find this stuff in the menus, however the easiest way to get to these items is to just start typing the name of the item. See below:
Search fastboot, click the boxes, choose install. Then search for ADB, click the boxes, choose install and then click apply. It's that easy it will download everything that's needed and install.
Time to open up a terminal:
Just to make sure we don't run into any problems we need to update adb and fastboot. In the terminal run these commands to update fastboot and adb (this is downloading them directly from Google).
wget https://dl.google.com/android/repository/platform-tools-latest-linux.zip
unzip \platform-tools-latest-linux.zip
sudo cp platform-tools/adb /usr/bin/adb
sudo cp platform-tools/fastboot /usr/bin/fastboot
You will also need the appropriate fastboot ROM. Fastboot ROMs available in this thread. The catch being that thread is no longer updated. So we will need to make our own fastboot rom. To do this we need two things:
1. The stock rom zip (OP Site).
2. Payload dumper. I've yet to get the one from the GitHub link to work, so I've been using the one from this Article. Direct Download Link
You need to extract the payload.bin file from the stock rom zip. Extract the payload_dumper files as well, and place everything in the same folder. Payload_dumper requires python3. Open up Synaptic again, search for python3.6 and install it. Now open a terminal so we can extract the images from the payload.bin.
Navigate to the location of payload_dumper and your payload.bin file. In my case my commands are:
cd Desktop <-- switches to the Desktop folder
cd payload_dumper <-- switches to the payload_dumper folder on the Desktop
python3 payload_dumper.py payload.bin <-- runs the payload_dumper "program" and extract the images from the payload.bin
Now would be a good time to back everything up. The phone will get wiped. Extract the fastboot images to a folder that is easy to find. I would recommend the Desktop.
Now it's time to flash all those images we just extracted using payload dumper. Place the phone in fastboot mode. You can do this using the advanced reboot menu, ADB, or the key combinations (all key combos listed below for reference):
Volume Up + Power while turning on will boot to fastboot.
Volume Down + Power while turn on will boot to recovery.
Holding Volume Up + Power should force the phone to turn off.
Volume Up + Volume Down should put your phone in Download mode for the MSM Tool.
You can flash the images one by one or use a script. My script is available here. Flashing the fastboot ROM should look something like this:
That image explained:
cd Desktop <-- Switched the directory to the Desktop the default directory when you open up the terminal is the /home directory.
cd flash <-- I put my fastboot images in a folder called flash. This stuff is case sensitive. My folder was all lowercase.
sudo fastboot devices <-- Is just checking to see if my PC can see my phone, and making sure it's in fastboot. Sudo is necessary for this distro, as both fastboot and ADB must be run as root.
sudo sh FlashThese.sh <-- Tells the terminal to run my script, since the script contains fastboot commands it must be run as root.
At the end you should get something like this:
Then just choose start form Fastboot (If you were previously on a custom ROM go straight to recovery and wipe everything). Not booting and getting dumped off at the OnePlus recovery screen is nothing to worry about. Choose your language of choice, Wipe data and cache, Erase everything (Music, pics, etc), This can not be undone, continue. After that the phone will boot. Once booted enable developer options, advanced reboot, and reboot to fastboot.
2. Installing TWRP.
First step is to boot the correct TWRP image. Grab the current TWRP from the official site. You need both files, the img file, and the installer. Once again from the terminal:
The image explained:
cd Desktop <-- Switched the directory to the Desktop the default directory when you open up the terminal is the /home directory.
sudo fastboot devices <-- Is just checking to see if my PC can see my phone, and making sure it's in fastboot. Sudo is necessary for this distro, as both fastboot and ADB must be run as root.
sudo fastboot boot twrp-3.5.2_9-0-fajita.img * <-- Sends that TWRP image to the phone to be booted temporarily. Only boot this, never run the command "flash".
Once in TWRP the phone should show up as a media device so you can copy files to it. Copy the TWRP installer over to it. Choose Install from the TWRP menu and navigate to where you placed the TWRP installer. Press on it, and swipe to confirm flash. When it is done hit the back button until you are back out to the main menu.
From the main menu choose reboot, and choose Recovery:
The first time you try and reboot the official version of TWRP it will ask you if you want to install the TWRP app. Do NOT install the app. In the settings you can disable this prompt. Your other option is just uncheck both boxes at the screen you see below when you get to it, and then click the button that says do not install. Do use the slider. At that point the phone will reboot as to recovery as you selected.
Now that you are back in TWRP that is now installed, time to wipe the phone. From the main menu choose Wipe. Swipe the factory reset slider at the bottom. Then hit back. Next hit Format Data. Type Yes to Continue. Hit back to continue. Keep hitting back till you get to the main menu.
Do NOT wipe cache, do not Wipe system, do NOT Wipe Dalvik / ART, do not add anything else, Just Factory Reset and Format Data. After doing those two Reboot to Recovery one more time. So go back into the reboot menu, choose reboot to recovery again (swipe to allow modifications if it asks). You must do this after formatting data.
3. Install Lineage
Links:
Lineage 18.1 XDA Thread
Official 6T Lineage Downloads
The phone should still be in TWRP at this point. You now need to copy Lineage to the phone. From TWRP's main menu choose install. Then navigate to your ROM .zip location and click on it. Then swipe to confirm flash.
Lineage will replace TWRP, so you need to reflash TWRP as well. Run the TWRP installer again. If it's not on the phone, just copy it over again real quick. On A/B devices ROMs get flashed to the opposite slot. Things like Gapps, Magisk, etc get flashed to the current slot. We need Lineage on both slots, so it must be flash again. Flashing it twice only needs to be done the first time as we need to get rid of OOS. For updates it just gets flashed once. After the TWRP installer has run, back out to the main menu, and choose reboot, then recovery:
Once back in TWRP flash Lineage again. From TWRP's main menu choose install. Then navigate to your ROM .zip location and click on it. Then swipe to confirm flash.
Now run the TWRP installer again. Back out to the main menu, and reboot to recovery.
4.Optional, Gapps
Links:
NikGapps <-- For Lineage 18.1 (Use the R Folders for Android 11. I recommend the "Core" version. I also tested Basic though if you want that level of Gapps. I strongly recommend you grab setup wizard out of the R Addons Folder, I used the regular setup wizard, not the pixel one.)
MindTheGapps <-- It's worth mentioning here Lineage recommends MindTheGapps for 18.1. Take your pick. I personally use NikGapps as I can use a "leaner" Gapps package.
Now that your phone is back in TWRP for the last time before booting up Lineage, it's time to install Gapps if you want them. This step is optional. Same as the other steps here, go to install, choose your OpenGapps package, Then navigate to your .zip location and click on it. Then swipe to confirm flash.
5. Very Optional, Magisk
These steps are very optional. However this is how I, root, pass safety net, and get a various apps to appear in the Play store.
Flash Magisk in TWRP. For Magisk 23, you now have to rename the Magisk.apk to Magisk.zip. Then flash it in TWRP. If you wanted to uninstall it, you rename it to uninstall.zip. If you already had an older version of Magisk installed, make sure you do not have it hidden / nenamed when installing Magisk 23 for the first time. Restore the original package before installing 23.
Magisk <-- Flash this right after Gapps.
These items are add-ons are flashed in Magisk after the first boot (Don't flash these in TWRP anymore):
MagiskHide Props Config
Busybox
To flash modules in Magisk press the puzzle piece icon. Then choose install from storage. Now just choose your addons. After flashing the icons it will have a reboot icon at the bottom. You can reboot or you can press back and flash another. After you are done reboot.
You will also need a Terminal Emulator. I personally use:
Terminal Emulator for Android
Once all these are installed the first step is setup Magisk. Under Magisk go to settings:
In version 20.4+ Magisk Hide is no longer on by default. So make sure the Magisk Hide, Hide Magisk from various forms of detection switch is flipped. Then press Hide Magisk Manager. This will bring up a box for you to choose a random name for the Magisk Manager, type whatever you want here. You can leave it Manager if you wish, but I typically change this.
Now open Magisk again. It will ask you to download it again, click ok, then manually open the app again as it says. Now we need to open Magisk hide. This is now under the shield icon, then click the arrow at the top:
These are the apps you don't want to know that you have root. Less is better. You can cause instability problems by just choosing everything. My general rule of thumb is, Google, steaming video, music, and payment apps get selected. In my experience if I come across an app that needs it and I didn't select it, I just clear cache and/or data and re-open the app and it works. There are some big multiplayer apps that ban hardware / people, so do your research (don't ask me, I don't play those games).
Next time to change the device fingerprint using MagiskHide Props Config Module. We do this using the terminal emulator. In the terminal emulator, type "su" to gain root privileges. Then type props to run the module:
Now it's just following the menus. Choose option 1 - Edit device finger print. (type 1, hit enter)
After this you will see a menu of devices. It doesn't matter what device you pick really. If you want apps / Google to think you have a OPPO or Samsung pick one of those Fingerprints. However there's a bit more to passing Safety-net than that. Since Google has changed how things work not all those fingerprints that used to work will work now. Also now you may get an error when you turn on the phone because of the security dates. The OP6T Android 10 fingerprint has no issues at this point, so use that if you want:
After choosing the fingerprint you want, it will ask you if you want to reboot. Choose yes. After rebooting, you may need to clear the cache from the play store for some apps to appear in it. You should now pass safety net. Check this in Magisk:
6. Very Optional, Ad Blocking with a Host File.
You can block many things with a hosts file, most popular would be ads. I've been use StevenBlack's host file which is a compilation of several hosts files. This is located on Github:
https://github.com/StevenBlack/hosts (Scroll down you'll see the options of what you can block)
Direct link to the hosts file I use. This will block Adware / Malware.
Unfortunately for quite some time now on this device you can no longer just use a root browser to swap the hosts file. The easiest way is to use TWRP.
First we have to make the hosts file. The hosts file must use unix / linux line endings. If you are using linux, don't worry about this, just create the file. If you are using Windows, the easiest thing to do is use Notepad++ (Free).
Notepad++ Downloads
Next one other caveat. The hosts file is quite large. I've never had much luck copy and pasting it from any other browser than Firefox (Windows or Linux), but however you get it into Notepad++ is not a big deal.
Once in you have the hosts file into Notepad++ go to Edit, EOL Conversion, and Choose Unix (LF).
Now save the file as "hosts" no ending. This does mean under file type you will need to change it to All File types *.*. Move this hosts file to your phone. Then reboot to recovery. From the main TWRP menu, choose mount. Then mount system:
Hit the back button and go to the advanced menu. Choose File Manager:
You will find your hosts file under /sdcard, wherever you placed it. In my case I placed it in a folder called ROMs. Once you locate it, press and hold it for a moment, and relase. Then choose copy file:
At this point you need to tell TWRP where you want to paste the hosts file. It belongs in the /etc folder. The only hic-cup here is depending on what you were doing in TWRP this could be (on this device) /system/etc or /system/system/etc (you will see similar folders to the image below if you are in the right place). Once you are there, press "paste?" button in the lower right corner:
After this just swipe to confirm:
You can now reboot the device, and your hosts file should now be in place. Your ad block should now be active for all apps as it's global for all connections.
7. Reboot to system.
Updating Lineage​
1. Flash Lineage.
Reboot to recovery. You can use the advanced reboot menu, or Volume Down + Power while turning the phone on. Don't wipe anything. From TWRP's main menu choose install. Then navigate to your ROM .zip location and click on it. Then swipe to confirm flash.
Lineage will replace TWRP, so you need to reflash TWRP as well. Run the TWRP installer again. After the TWRP installer has run, back out to the main menu, and choose reboot, then recovery:
2. Optional, Gapps (if you installed them once you must continue to install them or do a clean install)
Links:
NikGapps
Now that your phone is back in TWRP for the last time before booting up Lineage, it's time to install Gapps if you want them. This step is optional. Same as the other steps here, go to install, choose your OpenGapps package, Then navigate to your .zip location and click on it. Then swipe to confirm flash.
3. Reboot to system.
Last updated​Since I don't want people to have to wonder if these instructions are current, I am going to periodically test and update this post with my results. Please note I'm testing with a 6T, TMobile 6Ts are different. You can generally assume previous versions of LOS and OOS were also tested, but if you are unsure feel free to ask in this thread.
Last tested with:
OOS 10.3.7 and LOS 17.1 12-31 with TWRP 3.4.0-2
OOS 10.3.11 and LOS 18.1 05-27 with TWRP 3.5.2_9-0
This method has also been tested with:
OOS 10.3.3 and Omnirom 5-24 MicroG and Omnirom 5-24.

Cliff Notes
*TWRP 3.5.0_9-0+ Must be used with LOS 18 / 18.1
- Backup everything to the PC, so you will need to copy all your data over.
- Sync all your accounts, etc.
- In TWRP format data. Reboot recovery (This step wipes the device, make sure you backed everything up!)
- Factory Reset. (This is the slider at the bottom, do not Wipe system, do NOT Wipe Dalvik / ART, do not add anything else)
- Flash Lineage
- Flash TWRP Installer
- Reboot to Recovery
- Flash Lineage (This is only the first time, to get the AOSP rom on both slots, only do this for the first install)
- Flash TWRP Installer (This is only the first time, to get the AOSP rom on both slots, only do this for the first install)
- Reboot to Recovery (This is only the first time, to get the AOSP rom on both slots, only do this for the first install)
- Flash Gapps (Optional)
- Flash Magisk (Optional) (Remember for ver 22 the Magisk.apk gets renamed to Magisk.zip, can also be renamed to uninstall.zip for uninstalling)
- Reboot to System.
- Then you should be able to setup the device, copy everything back over. Restore your data.
After this you should be able to update Lineage as normal.
- Reboot to recovery
- Flash Lineage.
- Flash TWRP Installer
- Reboot to Recovery
- Flash Gapps. (Optional, but if you flashed them once you have to keep flashing them.)
- Flash Magisk. (Optional)
- Reboot to system.
- No loss of data, or anything.

Thanks for the guide, able to flash los 17.1 successfully.

How to go back to OOS?
Does anyone have a guide on how to go back to OOS after flashing Lineage according to Lineage's instructions?

Back up your data, use Step 1 of these instructions. That will put OOS back on your phone.
MSM Tool, always my least favorite option, but always an option.

Massive thanks for your instructions!
- at first, I tried upgrading from LOS 16.0 to LOS 17.1. I followed the instructions on the wiki, but it landed me in the qualcomm crashdump mode.
- after that I ran into your instructions, and tried to follow your update guide, but it didn't help (not very surprising I guess, but I haven't had much to lose at this point ).
- after that, I just followed your fresh install guide (i.e. flashing the fastboot room and starting from scratch), followed every step and it worked!
I wonder if it's worth updating lineage OS wiki and pointing to your instructions? There is bunch of people in this thread, who also bricked the phone into crashdump, so perhaps it could help to prevent it for someone else.

Updating to LOS 17.1 ?

Initially I had problems with updating LOS, so I returned to Stock. As more people attempted to install LOS, and this fine Original Poster "Ohio" offered such excellent, and detailed instructions, I have been running LOS 16 since February.
However, I have not updated it, since I have had Zero Issues.
But to clarify, you used this method to update to LOS 17.1 ?
- coming from LOS 16 - without first returning to a fast-boot ROM ?
Did you up-date GApps accordingly during this Flash ?
Thank You, in advance, for any assistance!
:good:

Hi, I updated my previous reply to make it a bit more clear!
Yep, I was on LOS 16. Haven't had any issues, but figured why not update if I'll have to do it eventually
So I downloaded 17.1 and used the wiki instructions, which messed the phone up
Ended up flashing fastboot rom and starting from scratch, flashed gapps and magisk according to OhioYJ's instruction and it worked.

I was using carbon ROM previously, had to move to OOS latest for flashing the lineage 17.1, believe it needs to be done if you are coming from pie, people know better correct me if I am wrong here.
As Karlicoss mentioned, it's better to follow the method posted by Ohio.

Cliff Notes Versions
Installing Lineage
- Install fastboot ROM boot it once. Just to make sure everything is good.
- Reboot to fastboot.
- Boot the image of TWRP.
- Run the TWRP installer, reboot to recovery
- You backed everything up right?
- Factory reset (This is the slider at the bottom in the wipe menu).
- Format data. (This is the button that says Format data in the wipe menu)
- Do NOT wipe cache, do not Wipe system, do NOT Wipe Dalvik / ART, do not add anything else, Just Factory Reset and Format Data. After doing those two Reboot to Recovery one more time. You must do this after formatting data.
- Now transfer Lineage and TWRP to your phone, Windows / Linux should see TWRP fine as a media device when plugged in.
- Install Lineage
- Run the TWRP Installer.
- Reboot to Recovery.
- Install Lineage (You need Lineage on both slots, so yes run it again)
- Run the TWRP Installer (yes again).
- Reboot to Recovery.
- Install Gapps if you want them.
- Install Magisk if you use Magisk. Do not install modules or other add ons at this point. Boot once and go through the setup and everything, then install your add-ons.
- Be aware the phone may restart once, then Lineage will start up and all will be good.
Updating Lineage
- Reboot to recovery
- Flash Lineage.
- Flash TWRP Installer
- Reboot to Recovery
- Flash Gapps. (Assuming you use them, if you installed them once you must continue to install them or do a clean install)
- Flash Magisk. (Optional If you use it)
- Reboot to system.
- No loss of data, or anything.
- No need to flash anything twice etc.

Usually this means you didnt format data, or you are using an old version of TWRP. Did you do a clean install?
I just tried it on my phone, was running 4-12 build, using 3.3.1-32 TWRP, updated to the 4-14 build, using 4-14 Gapps (nano), everything went smoothly here.

Just cycling airplane mode doesnt work? This isn't a TMobile 6T is it? You are in Sim slot 1? You maybe better asking in the LOS thread, and provide log it not working and then it working when you reinsert it. Im not quite sure whats going on there.

@OhioYJ So for an update you boot to recovery flash LOS latest version then flash twrp again and then reboot to recovery second time then format data to possibly decript encrypted system and, transfer files both gapps and magisk to device and then install gapps and magisk, lastly just reboot to system?

reply
yes it is a tmobile but it was flashed to global. TWRP is the version you are using. downloaded the lastest ROM. Weird it finds LTE at first then like I said when then phone shuts off LTE doesnt work til I take sim out.

No that would be ridiculous. Not necessary at all. You have something else going on, but I dont know what. My update procedure is exactly as listed on the OP, on two 6Ts, two different carriers.

A TMobile "converted" to global does not equal a global 6T. Logs posted in the LOS thread, may help out other TMobile users? The TMobile 6Ts introduce all sorts of quirks, and Im afraid I dont have any experience with them, so hopefully another TMobile user will be able to help.

Features
A quick glossary and primer on flashing & slots for A/B devices (like ours):
Spoiler: Show/Hide
- "Clean flash": Removing device protection & clearing user settings before installing a bootable system install zip (usually by either wiping or formatting data, see below).
- "Dirty flash": Flashing a ROM zip (usually upgrading to new version, sometimes just re-flashing the existing one) without wiping data or anything first.
- "Wipe data": Synonymous with "factory reset", accomplished from TWRP recovery by selecting "Wipe", then performing the "Slide to factory reset". Clears user data without erasing any partitions, removing encryption, or deleting contents of internal storage.
- "Format data": Formats the data partition itself, resets all file-based encryption keys, loses all contents of internal storage, and in fact deletes all "user 0" directories (this has some implications for internal storage before & after first boot).
- "User 0" directories are a series of directories that store userdata for the primary user, "Owner", and get created in various places throughout the filesystem on first system boot if they don't exist already. Anything you copy to "internal storage" while booted in recovery after "formatting data" will actually be copied to /data/media/ instead of /data/media/0/, and will become invisible to regular file browsing after first boot once the system has created /data/media/0, since the system will prefer to use that path for internal storage from then on (so you'll need a root file browser to delete things from /data/media, or just ADB sideload things instead of copying after formatting but before booting).
- "OTA package": Originally an abbreviation for "over the air", referring to how a software update could be delivered (as opposed to having to take your phone to a carrier's store for a firmware update via serial/USB connection). The common usage in Android circles is any installation zip file that actually includes a bootable system.
- Some partitions are duplicated (system, vendor, boot, and probably a couple others, but not data) and have a "slot A" & "slot B" copy.
- "Slot A" and "slot B" are absolute designations, but most installer zip scripts use the relative designations: "active" and "inactive". Whichever slot you're booted from currently is "active", and the other one is "inactive".
- Installing a zip file that's flagged as being an OTA package will 1) install the contents to the "inactive" slot, and then 2) flag the bootloader to switch which slot is considered "active" (and booted from) and "inactive" upon next reboot.
- The OxygenOS full OTA zip files and all custom ROM installer zip files are considered "OTA packages" and will trigger a slot switch on next boot after installation.
- You can install multiple OTA zip packages one after the other without rebooting in both the stock recovery and TWRP; they will all get installed into the correct partitions in the "inactive" slot, one on top of the other, and then it will swap active & inactive upon reboot.
- We don't use what are called "delta" updates, which can patch existing partitions by block or by file; we use full filesystem images. So for us, OTA zip packages are really just a bunch of partition filesystem image files all wrapped up into a "payload.bin" with some extra instructions & metadata/checksums, so when you flash a ROM, it overwrites entire partitions at a time instead of individual files or filesystem blocks within that partition. So if you've changed something in a partition like system that gets written as part of flashing an OTA zip, all your changes are gone. The only thing in the system partition afterward will be what was in the system.img that was included in the ROM zip payload.
- The partitions that crDroid, LineageOS, and most custom ROMs for OnePlus 6 & 6T install to when flashing are boot (contains recovery & kernel), dtbo, system, and vbmeta. Some ROMs (like Syberia) build the vendor partition from source instead of just trying to work with the existing OEM vendor partition, so they flash that one too when installing. So you definitely need to flash stock vendor before switching from Syberia or another source-built vendor ROM to one like Lineage or crDroid that uses prebuilt.
- "Prebuilt vendor" vs. "source-built" vendor partitions: when first trying to get a custom ROM working on a new device now that we have separate system & vendor partitions & Google's "Project Treble" is a thing, you'll often just leave the contents of the vendor partition alone, because that's where all the proprietary or device-specific stuff lives (manufacturer specific hardware drivers & interfaces, any DRM libraries, custom frameworks & selinux policies for talking to them), and you make a compatibility map of what framework versions you're compiling against in system and what vendor version they're compatible with or supersede or you overlay updated things that should replace stuff in the vendor partition and keep it in system_ext instead. But you're also limited in that if there are some things in vendor, you CAN'T work around it from the ROM side (like, OnePlus Camera working correctly). So often, once the basics are functioning, the goal is to move to building the contents of the vendor partition from source, because you then have the freedom to fix problems with sepolicy, library/framework mismatches, etc. and make things work with the custom ROM instead of only working with the OEM's flavor of Android, and you can still copy individual pre-compiled files from the stock vendor filesystem image if needed (like if there's no open-source equivalent for some driver). Unfortunately, OnePlus SDM845 (enchilada & fajita, the OP6 & OP6T) never got a proper source-built vendor bringup by the LineageOS team (upon which crDroid is based). And while Syberia has had source built vendor in Android 11 (possibly 10?), it was only done for enchilada and NOT fajita, it's not trivial to unroll & commonize what they've done to apply to other ROMs, and some of the proprietary files they keep are imported from other similar devices/similar chipsets rather than source-built (presumably because the OnePlus ones are modified in a weird way that the open-source components can't hook into, but still not ideal). So for fixing a lot of the issues we still face with lack of things working quite right, or hardware features not available in custom ROMs (especially compared to newer OnePlus devices like the 7, 8, or 9 series), we're kinda stuck, because you can't just implement it against the stock prebuilt vendor.
- "Updating firmware" simply means we're flashing updated contents from the manufacturer into all the OTHER partitions besides the ones that the ROM OTA zip touches. There are another dozen or more of those, besides system & boot, that the full OxygenOS OTA zip would normally write to when you install it. The contents of the system partition in custom ROMs for our device are generally built against a particular version of OxygenOS (mostly the contents of the OEM vendor partition), and we've recently had an entire major Android version update come through from OxygenOS. Some people are still on older firmware that is now dramatically different than what the current custom ROM was intended to deal with (that is, all the stuff from OxygenOS is still based on Android 10, while the ROM is expecting compatibility with Android 11), and while I tend to agree that OxygenOS 10 was better than the current state of OOS 11, that doesn't matter when you're talking about installing the custom ROM over it. So please, keep an eye out in the release notes for what the recommended/required firmware versions are, and remember to update (procedure below).
Notes on custom recoveries with OxygenOS 11 firmware:
Spoiler: Show/Hide
- My understanding (from people smarter than me) is that the android-11 tree of TWRP is kind of a mess at the moment. I had made some 3.6.0_11-0 unofficial builds for both enchilada & fajita, but now they don't even seem to boot and I don't know why. TWRP android-11 tree refuses to mount the system partition where it belongs, and so addon.d OTA survival scripts don't work correctly any longer (which means you're hosed if you use NikGapps and update while booted from a TWRP version ending in "11-0", or if you have Gapps installed as a module and forget to reboot recovery & re-flash Magisk after flashing an update from TWRP).
- Trying to `fastboot boot` an Android 9-based TWRP image (like official 3.5.2_9-0 twrp.img) after installing OxygenOS 11 doesn't work, and will drop you into Qualcomm Crash Dump mode. Don't try to flash it as your boot partion, either.
- Meanwhile, stock LineageOS-based recovery, for all its shortcomings, has working fastbootd (aka "Userspace fastboot", which is what happens when you go to "Advanced", then choose "Enter fastboot" and the background colors go from purple to orange) that lets you flash both slots at once and unlocks critical partitions, while the OnePlus OEM bootloader (where it says "Fastboot Mode" in a square, then goes to the big green "START" text over white & dark red terminal font type text) can't be used to flash every partition to update firmware. Personally, I still think of it as wannabe-class and not a "real" custom recovery until the Lineage team 1) implements userdata decryption so you can manage files in /data and install updates from internal storage, and 2) allows for a factory reset the way we've always all understood it ("wipe data") WITHOUT nuking the contents of internal storage for no good reason ("formatting data"). But since crDroid is LineageOS-based, it's what we've got, and fastbootd is the best way to update firmware.
- With all that being said, since it's likely TWRP will only get MORE broken with Android 12 looming large, we're officially only going to support the built-in LineageOS-based recovery & OTA updater moving forward, until things change dramatically. If you want to try different custom recoveries (new builds of TWRP, OrangeFox, PBRP, whatever), feel free; and let us know how it works! But you're on you're own doing that.
- And on the system update side, applying system OTA updates seems to work correctly using the built-in Updater tool (Settings > System > Updater) both with new OTA releases and when choosing a file from "Local Installation". It executes OTA survival scripts correctly from /system/addon.d/ as well. I've personally tested and it correctly preserved Magisk v23 canary and MindTheGapps & NikGapps (on tester fajita) and MinMicroG "system" install package on my daily driver enchilada.
- ...however it has an accidental dependency on Magisk, due to things beyond my control upstream in the ROM. Whoops. Won't work if you don't have Magisk installed.
- FLASHING the old official TWRP 3.5.2_9-0 INSTALLER zip (or newer) on top of OOS 11.x DOES seem to work for now, but you need to be in a recovery environment that allows you to flash that installer in the first place (either by booting into an already-installed TWRP recovery before updating firmware, or by having an Android 11 compatible recovery boot.img to be able to `fastboot boot`). I don't know if it'll keep working in Android 12 or with crDroid 8.
- Look, if you really want to stick with TWRP, I don't blame you. I made bootable Android 11 compatible TWRP images for enchilada & fajita back at 3.5.2, and they still work well enough to `fastboot boot` them and then flash the old official 3.5.2_9-0 installer zips. Look at the attachments at the end of post #2. Also, you may want to try one of Siddhesh's custom recoveries; they probably work even better.
- TL;DR: I prefer TWRP too but current official releases are kinda broken and it's a chore to get the old version installed correctly, so built-in LineageOS-based recovery and Updater app are the supported way to install & update moving forward.
Prerequisites:
- Make sure your bootloader is unlocked (and don't plan on relocking it ffs).
- Make sure you have a reasonably-current, working installation of android platform tools (adb & fastboot command line binaries & necessary drivers) on your computer, with a known-good USB cable (see links in post #2).
- Make sure you've downloaded the most recent full OxygenOS OTA installer zip (11.1.2.2), crDroid zip, matching crDroid boot.img, and whatever Magisk/GApps/microG installation packages you want to use to your computer (see links in post #2).
- Make sure you've backed up whatever data you want to keep to somewhere that's not on your phone; for a new install, we're going to format the data partition and you're going to lose everything from internal storage.
Let's get started!
Updating firmware:
- Reboot to bootloader (with no USB cable connected).
- If you're not already using the stock (LineageOS-based) recovery, you'll need to `fastboot flash boot path/to/boot.img`, substituting in the path & filename for the current crDroid boot.img that you downloaded as part of the prerequisites.
- Reboot to bootloader again (actually loads new bootloader that you just flashed).
- Use Vol +/- buttons to select "Recovery mode" and press Pwr button to boot stock recovery (white & purple on black color scheme, LineageOS logo in the middle).
- Tap "Advanced", then tap "Enter fastboot" (the already-selected first option), and color scheme should change from purple to orange.
- Follow the instructions for extracting the partition images from the official OxygenOS Updater full OTA zip you already downloaded using the "payload-dumper-go" utility, and flashing them one at a time, from https://wiki.lineageos.org/devices/fajita/fw_update, except for the very last command ("fastboot reboot").
- Since those instructions were updated for Android 12, and this is still Android 11-based & depends on using the OxygenOS prebuilt vendor partition contents, you'll also need to run fastboot flash --slot=all vendor vendor.img at the end of the list of commands in the linked LineageOS Wiki article above.
- If you're only updating firmware and were already on crDroid, you can just "fastboot reboot" which will go back to system. If this is part of coming to crDroid from another ROM, continue with the instructions below.
First time installing crDroid to your OP6T, coming from stock OxygenOS 11.x or another ROM (stock LOS-based recovery):
- Update to OxygenOS 11.1.2.2 firmware as described above if you haven't already.
- At the end of that procedure, (re)flash the crDroid boot.img to the `boot` partition of both slots, then reboot to recovery.
- Once you're rebooted into stock recovery (and lo, it was most purple), ADB sideload the crDroid installation zip. It might prompt you with "Install anyway?" on the phone, so don't just walk away from it.
- After the adb sideload has finished and the purple menu at the top comes back, hit the back arrow, then choose "Wipe data" (which WILL format internal storage -- you backed up as noted above, right?).
- Reboot to recovery (causes it to switch slots so any further installations will be on top of the slot that it just installed crDroid into).
- ADB sideload Magisk and/or any GApps packages you want to use. Please note that any time you install something via ADB sideloading, that the install file is technically renamed "sideload.zip" in transit by the ADB protocol, which might cause problems with installers that try to get too clever for their own good and alter behavior based on renaming the installation zip (like MinMicroG), so you might have to get even MORE clever with changing up installation order (like flash MinMicroG/GApps before Magisk so it won't install as a module. I dunno, talk to the package installer authors to get them to just build multiple packages or talk to the LineageOS devs to allow you to decrypt internal storage, copy stuff to internal storage via MTP, and install stuff from internal storage like a proper custom recovery (or at least maybe `adb push` to an unencrypted temp dir in the data partition).
- Reboot system.
- ???
- Profit!
OTA updating from Updater app with OOS 11.x firmware (recommended):
- This is the preferred way now. You just go to Settings > System > Updater, and... install an update. It processes addon.d OTA survival scripts correctly (tested with Magisk, MinMicroG, MindTheGapps, and NikGapps).
- Please note that there's currently an accidental depencency on Magisk being installed for this to work. I don't know if this will get fixed; that's definitely above my pay grade. This appears to have been fixed; huzzah!
- If you're trying to do a "Local Install" of the downloaded zip, please note you NEED to download on a computer & transfer to internal storage via USB cable; downloading files from an app on the phone associates it with a particular app thanks to Android 11+ Scoped Storage/SAF bull**** and will cause the file to be unreadable to the updater app process.
-- Old TWRP-based instructions below the fold (not recommended, but keeping for historical value... probably not accurate but I'm not going to update them more) --
Spoiler: Show/Hide
OTA updating from TWRP with OOS 11.x firmware:
You don't need to remove device protection; it works fine with PIN. Be sure you have a PIN set, or have looked up whatever that arcane chart of pattern > numeric incantations in case of pattern unlock. It's awful.
- Boot into TWRP recovery.
- Choose install, then select crDroid.zip, select additional zips, choose the TWRP installer zip, then slide to confirm flash.
- Reboot recovery.
- Choose install, then select Magisk zip (if using), select additional zips, choose GApps/microG (if using), slide to confirm flash.
- Please keep off of the grass, shine your shoes, wipe your... dalvik.
- Reboot system.
OTA updating from TWRP with OOS 10.x firmware:
- Don't. Update firmware to 11.1.2.2 first.
Reporting bugs:
I'm a parent of three young kids whose industry disappeared in the pandemic and is now full-time house husband & parent-in-charge while my wife is teaching full-time, I'm trying to save my small live-event-turned-streaming-studio company in my spare time. I'm doing in-home caregiving for a family member overnight one day a week. This is the back-up spare-spare-time hobby. I'm not a software developer nor do I know any programming languages, I just wanted a ROM with signature spoofing support and more customization than the unofficial microg-compatible LineageOS builds. So if there are bugs or feature requests, I go over to the crDroid dev chat and ask if someone has time to hold my hand & help. Don't make me get yelled for annoying them, mmkay? That said...
- Logs/screenshots/recordings or it didn't happen. Either the built-in Matlog app, or Syslog (free, open source, available on Play store and F-droid) are your friends here.
- I try to keep an organized notebook of roadmap, feature reqeusts, bug reports, etc. I won't always be able to fix it, but I'll at least look and do my best to ask the actual devs.
- I don't sign into XDA much, so if I haven't said anything, check out the Telegram group. Lots of helpful folks there.
- Please keep your questions in this thread instead of PMing me with them directly, so that the entire class can benefit from the discussion and you can find out if it's just you or if this is a widespread issue.
It's your device to use the way you want of course, and I use Magisk & microG and like to tweak things myself. But don't expect much support if you:
- didn't do a clean flash.
- aren't using the built-in kernel.
- are using extensive modifications (besides Magisk) like Xposed/Riru, Dolby Atmos, Viper4A, etc.
- immediately start using "finalize.zip" or flashing migrate restore zips instead of following the actual instructions.
- are running decrypted.
- re-locked your bootloader for some reason... you're on a custom ROM; don't do that.

Notes:
- crDroid 7.x (based on Android 11 & LineageOS 18.1) is no longer being actively developed, and I don't know how long someone on the dev team will keep merging monthly security updates. I'll try to keep building releases as long as there are updates, but all my limited time is focused on 9.x/Android 13 bringup now. We're in maintenance mode now, so any outstanding bugs are likely to just remain for perpetuity.
- Yes it supports package signature spoofing permission for microG compatibility out of the box (but will work without ANY GApps/microG implementation installed as well).
- Maintainer does not use GApps, so cannot answer questions about which packages work best from firsthand experience. In general, go with the smallest package you can and then install other Google apps from the Play Store. Please note that if you replace the stock dialer with Google Dialer, you may lose access to the Phone Info menu (*#*#4636#*#*) until you install another dialer. For recommendations, see https://wiki.lineageos.org/gapps.
- Requires OOS 11.1.2.2 firmware (last official release). You should consider using an Android 10 ROM if you want to continue using Android 10 firmware.
- Tested against latest Magisk 24 (with zygisk instead of magiskhide), works well.
- No there won't be official builds with inline GApps; please don't ask.
crDroid 7.30 - May 2023 ASB release notes/changelog:
Changelog since v7.29 official release:
- Merged May 2023 Android Security Bulletin from upstream.
- Whatever the ROM dev team changed upstream in LineageOS and crDroid sources (not much? they're busy with Android 13).
- No changes to device-specific files.
Known issues:
Fajita-specific:
- If you use App Lock and/or Face Unlock, you'll likely run into issues with the FOD circle view starting to flicker randomly into view when it shouldn't be there (like it's not dismissing properly because one part of the security handling is fighting with or doesn't notify the other part that it's done and doesn't need to try to accept a fingerprint any longer). As a knock-on effect, this will also cause "Disable Night Light when FOD is visible" to freak out. I have one person who doesn't use either report that they were getting the random FOD circle anyway, so... if you're having this problem, please make sure you've given MatLog permission to manage files so that it can actually save logs to internal storage and capture a logcat & send it to me. Logs or it didn't happen, etc etc.
Common:
- No f2fs-formatted userdata support, sadly. Doesn't work with the prebuilt vendor partition required for this version of Android. You'll need to reformat data to ext4 before being able to boot (you can fastboot flash the crDroid 8.x or 9.x boot.img if you need a recovery that will let you choose).
- Google Hotword recognition might be kinda broken right now (on more than one custom ROM/device, not just us), and may cause some screw-up that prevents microphone audio from being allowed to go anywhere else if it's enabled.
- If you are stuck at "Android is starting..." looping endlessly, then press power, reboot to bootloader, and follow the instructions for updating firmware to OxygenOS 11.1.2.2 in the first post. It doesn't wipe data, you shouldn't lose anything.
- Some screen-off gestures may not work, due to limitations beyond my control; don't use those gestures. Sorry.

(Please note that since crDroid 7.x/Android 11 for this device depends on the prebuilt OxygenOS vendor partition, you'll also need to add fastboot flash --slot=all vendor vendor.img to the list of commands in the instructions, just before the final fastboot reboot.

hi dev thanks for this rom i have successfully installed now, so there is a small info i like to share, that is installing any version of nikgapps apart from core nikgapps will result in bootloop or after even format the data, rom will boot but set up screen says it crashed, so i have installed with core version of nikgapps, rom booted successfully. that's all i have info to share now.

Hi dev ROM is working fantastically after installed all the application I used before, so thanks for it, it has enough customization thanks for it too.

Does NOT work on Verizon.

Hi devs i don't know the reason why this happening, the problem is when i change default launcher to nova launcher system ui automatically crashes, i can't specifically pinpoint the reason, but after launching the Paytm app for first time then paytm also crashed so i don't know what to do now. I have attached logcat from matlog so I think I have captured required info.

Thanks for the ROM. Where is the best place to get A11 gapps?

Hi LiveDisplay color profile doesn't work ,setting a profile ,once you exit it resets back to normal again

Excellent ROM.
Thanks!

Hi dev i attached a video, in which i try to explain a problem, i can't pinpoint say amazon app only having this kind of problem, but i can say irresponsible of which app suddenly ui will have some kind of problem, it will appear from nowhere after that phone will hang and i need to restart the phone or else battery drains very fast. Kindly look into it. I reinstalled the rom two time freshly, even though it having same kind of problem presist, but i really loved one good feature that is finger print working fantastic even after reboot. OS is not crashing and reboot by itself, app also not crashing but suddenly some part is acting wired. Anyway i will upload the video for proof. I have attached gif file as per xda rules.

I have one last idea in my head instead of using app called migrate to take back up of application installed in my phone and restore to newly installed rom. Better use play store to install all app one by one and see there is any difference, i really love this rom thats why i reinstalling freshly again and again to see any difference possible

I've never used micro g a whole lot in the past but I'm all for it now due to the unbelievable amount of permissions apps ask for and while I love Android I'm no Google person either. I flashed 7.2 CrDroid two days ago and didn't install gapps. Then I went back in twrp and flashed micro g and fdroid from (stable) nano droid installer thread here on XDA. Going to read up more about micro g ..etc.. Op, if you are testing anything that has to do with this or anything feel free to msg me anytime. Ill run whatever through everything possible and gather logs if need be and send them to you properly. Thanks for this rom!! Great job!! Always loved CrDroid! Think i 1st used CrDroid back in 2013 or so. Fantastic rom!! My Screen time on 7.2 CrDroid.

!DISCLAIMER!
Most people I know (including myself) who used my Guides and steps, did that with success many times. If you don't follow exactly the steps or you do a mistake during the process, I do not take any responsibility for any unexpected results or damage that may happen. However I am here to help if something goes wrong, just ask in the thread.​
AMD RYZEN FASTBOOT FIX
Some AMD Ryzen Systems may have problems to recognize your device in fastboot. Try the following ways:
1. Install AMD Ryzen Chipset Drivers.
2. Enable USB Debugging at device (Settings > Additional settings > Developer options > USB Debugging) and give authorization after connecting it to PC.
3. Use USB Hub.
4. Use USB Type-A 2.0.
5. Download this .bat file (unzip it) or manually create a .bat file with these lines below, and run it as an administrator, then reboot:
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbflags\18D1D00D0100" /v "osvc" /t REG_BINARY /d "0000" /f​reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbflags\18D1D00D0100" /v "SkipContainerIdQuery" /t REG_BINARY /d "01000000" /f​reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbflags\18D1D00D0100" /v "SkipBOSDescriptorQuery" /t REG_BINARY /d "01000000" /f​Check the steps an another user did to make it work here.
If this doesn't help, unfortunately you have to use Intel System.
UNLOCK BOOTLOADER
Note: Some AMD Ryzen Systems may have problems to recognize your device in fastboot. [Read the AMD Fastboot Fix Guide above]
Please keep in mind by Unlocking Bootloader the device will reset and all your data will be lost. Make a backup of your data first to PC or to USB.
1. Create a Mi account on Xiaomi’s website.
2. Add a phone number to your Mi account.
3. Insert a SIM into your phone (If you haven't added already).
4. Enable developer options in Settings > About Phone by repeatedly tapping (7 times) on MIUI Version.
5. Link the device to your Mi account in Settings > Additional settings > Developer options > Mi Unlock status. Also enable USB Debugging.
6. Download the Mi Unlock app (Windows is required to run the app).
7. Run the Mi Unlock app and follow the instructions provided by the app.
8. Reboot your device into Fastboot mode. For that simply turn off your device, press the Power Button + Volume Down (–) button at the same time. Then connect the device to the Windows PC/laptop via a micro USB cable.
9. After device and Mi account are successfully verified, the Bootloader should be Unlocked and your device will restart by itself.
INSTALL CUSTOM RECOVERY
Fastboot Method (No Custom Recovery currently installed)
Note: Some AMD Ryzen Systems may have problems to recognize your device in fastboot. [Read the AMD Fastboot Fix Guide above]
1. Make sure your Bootloader is Unlocked.
2. Enable developer options in Settings > About Phone by repeatedly tapping (7 times) on MIUI Version.
3. Enable USB Debugging in Settings > Additional settings > Developer options > USB Debugging.
4. Download a custom recovery of your choice. [You can find a recovery of your choice in my Collection]
5. Download the portable Minimal ADB and Fastboot and run adb.exe
6. Reboot to Fastboot mode by pressing Power Button + Volume Down (–) and keep holding both buttons until the word “FASTBOOT” appears on the screen, then release.
7. Once the device is in Fastboot mode, connect your device to PC and verify you can find it by typying in adb: fastboot devices.
8. Flash Recovery by typing in adb: fastboot flash recovery <recovery_filename>.img (The file may not be named identically to what stands in this command, so adjust accordingly).
9. Reboot to Recovery by typing in adb: reboot recovery or manually hold Power Button + Volume Up (+) until you boot to Recovery.
10. Done! You now have a new Custom Recovery installed.
Recovery Method (Custom Recovery already installed)
1. Download a custom recovery of your choice. [You can find a recovery of your choice in my Collection]
2. Reboot to Recovery by holding Power Button + Volume Up (+).
3. Press Install Image.
4. Locate the recovery.img you recently downloaded.
5. Select it and choose the option Recovery and Flash.
6. Go back and Reboot to Recovery.
7. Done! Your new recovery should be installed.
MAGISK ROOT SOLUTION
The easiest way to root your device is via Magisk, it should work in all ROMs, Stock and Customs.
Install Magisk:
1. Install latest TWRP Recovery. [Read the Install Custom Recovery Guide above]​2. Download the Magisk [You can find it in my Collection]​3. Reboot to TWRP Recovery by pressing Power Button + Volume Up (+) and flash it.​4. Reboot and check whether the Magisk app is installed. If it isn’t installed automatically, manually install the APK. [You can find it in my Collection]​Note: From Official TWRP Recovery 3.5.1 and onwards (and other recoveries based on that), Magisk.apk can be flashed as apk without the need of rename it to .zip. So you can simply flash the Magisk.apk in TWRP.​Manually Creation of Flashable Zip:​Download the latest Magisk APK and rename the Magisk.apk → Magisk.zip.​
Uninstall Magisk:
Flash the Uninstall.zip in TWRP Recovery and reboot. [You can find it my Collection]
If Magisk App isn’t uninstalled automatically, manually uninstall the app.
Manually creation of Flashable Uninstall Zip:
Download the latest Magisk APK and rename the Magisk.apk → uninstall.zip
Uninstall Magisk directly through the Magisk app. Simply press the Uninstall button.
DISABLE FORCE ENCRYPTION (DFE) & Encryption
[You can find it in my Collection]
Disable Force Encryption
Disable Force Encryption (a.k.a DFE) is flashed during installation of a custom ROM to avoid the system encrypting /data partition when the devices boot for the first time.​Some ROMs are not encrypted by default and so is not necessary to flash DFE. However if your ROM comes with encryption by default you can always flash DFE after clean installation of ROM and always after every update or flash or you can use any custom recovery like OrangeFox, Pitchblack, Skyhawk Recovery Project which can automatic flash DFE after every flash.​I don't recommended to use DFE if you don't switch ROMs frequently and you are casual user. Beside the fact that if you lose your device your data are not protected, many people get in confusion while doing OTA or manually updates, which if the ROM is encrypted by default and flashed DFE and in next update you forget to flash DFE you will lock out from your data and you wil get into bootloop (use custom recoveries mentioned above to avoid that).​​
Encryption
Warning - This works only on clean flash:
1. Flash ROM.zip in recovery
2. Mount vendor partition in recovery (for some reason does not mounting with newer TWRP).
3. Flash encrypt.zip.
4. Reboot to system.
Note:
The encrypt zip needs to be flashed after every update.
So flash ROM.zip and follow with encrypt zip.
Encrypted ROMs are recommended if you are stable and casual user of a ROM. Encryption have the benefit to protect your data, in case you lose your device for example. ​Always use the latest TWRP Recovery so you can be able to decrypt the data by filling the same lock screen password you have set in ROM.​Some ROMs are not encrypted by default but devs provide an Encryption.zip (script) which can encrypt the ROM. Same as DFE you need to flash it after clean installation of ROM and always after every update to stay encrypted and not get into bootloop. Unfortunatly there is not any custom recovery automatic doing that like with DFE, so you must be careful, avoid doing OTA updates and flash it every time you manually update a ROM.​
BATTERY TIPS
Advanced Guide
Simple Battery & Charging Tips
Improve your SOT
Battery Calibration
Steps:
1. Discharge your phone fully until it turns itself off.
2. Turn it on again and let it turn itself off.
3. Plug your phone into a charger and, without turning it on, let it charge until the on-screen or LED indicator says 100 percent.
4. Turn your phone on. It's likely that the battery indicator won't say 100 percent, so plug the charger back in (leave your phone on) and continue charging until it says 100 percent on-screen as well.
5. Unplug your phone and restart it. If it doesn't say 100 percent, plug the charger back in until it says 100 percent on screen.
6. Repeat this cycle until it says 100 percent (or as close as you think it's going to get) when you start it up without it being plugged in.
Overheating
Following reasons will lead to device heating issue:
During the initial setup after purchase or when restoring data.
Downloading large files.
Using apps that require more power or using apps for extended periods such as:
Playing high-quality games for long time.
Recording videos for extended periods.
Streaming videos while using the maximum brightness setting.
Using the Screen Mirroring / Smart View feature (connecting mobile to a TV).
While multitasking or when running many apps in the background i.e:
Using Multi window.
Updating or installing apps while recording videos.
Downloading large files during a video call.
Recording videos while using a navigation app.
Large amount of data for syncing with the cloud, email, or other accounts.
Exposing device under sunlight when temperature is high around you.
Extensive usage of mobile hotspot and tethering feature.
Using device in areas with weak signals or no reception or in roaming network.
Charging the battery with a damaged / unapproved USB cable.
Device's multipurpose jack is damaged or exposed to foreign materials, such as liquid, dust, metal powder, and pencil lead.
Solution:
Turn off Wi-fi, GPS , bluetooth and other connectivity options when not in use by dragging the notification panel.
Decrease screen brightness.
Close background running applications.
Too many applications installed in device may result in device heating since their corresponding process will keep on running in background. It is advised to uninstall un-necessary apps if not using them.
Avoid using apps like GPS, data dependent apps or graphic intensive games for longer duration since they require more energy to function, causing device to heat.
It is advised not to use device while charging as it may cause the device to over heat.
General:
DO:
Use manual brightness or dim the screen.
Turn off notifications for apps you don't use. Better still, delete/disable the apps entirely if you don't need them.
Enable battery or power saving mode when you want to extend your battery life.
Use the power adapter that came with your phone. Other chargers can charge slowly/faster but they can also damage your phone or battery.
Turn off bluetooth, location tracking, and Wi-Fi (unless you are actively using it)
Turn off print services from bluetooth connection preferences.
Avoid extremes of heat and cold. If your phone gets very hot or cold it can strain the battery and shorten it's lifespan.
DON'T:
Have Bluetooth or Wi-Fi turned on constantly.
Leave apps running in the background. Instead restrict background usage off apps that you don't need running.
Push email means your device is always listening for new email which drains alot of battery.
Drain your phone battery all the way to 0% or charging it all the way to 100%. Keep it between 20% - 90% for longer battery lifespan.
The more advanced the graphics and animations are (games, videos, photos, animations), the harder the processor and graphics chip in your smartphone have to work. More activity means more battery use.

How to block ads on Android.
General:
Always prefer Open Source or well popular Programs, Apps, ROMs, Kernels & Stuff.
Open Source doesn't mean it's 100% safe but it's unlikely to have something suspicious, since you and other users can check the code in GitHub or in any other code hosting platform the "stuff" is hosted.
Prefer ROMs & Kernels with SELinux Enforcing. You can find informations here.
Always download and install Apps, Programs, ROMs & Stuff from official sources and do not use redirection links from different sites. Google is your friend to find the official source of the stuff you want.
Always check the permissions an app requires, before download and install it to your device. If an app ask for permissions which has nothing to do with the app functionality then it's should be reconsider or ask the developer why these permissions needed.
If you want to avoid Google and Play Store (De-Google), you can choose a ROM without GApps preinstalled like LineageOS and use F-Droid client which is an installable catalogue of FOSS (Free and Open Source Software) applications for the Android platform. The client makes it easy to browse, install, and keep track of updates on your device. Note that not all apps from Play Store will be available in F-Droid. Only Open Source projects. You can find alternatives though.
Alternative you can use LineageOS for microG or any ROM which support signature spoofing and can support microG.
For Windows use the default Windows Defender & Malwarebytes to scan your files whenever you want (Prefered before open or install them). Also use the addon/extension uBlock Origin in your Browser. These should be enough for normal users.
For Android Do not use any antivirus - antimalware since it's useless, just check what apps and from where you installing.
Always verify the source of addons/extensions in your browser. Avoid installing random and unpopular addons/extensions. Keep it minimal and clean, so browser can be fast and safe, no need bunch of extensions.
If you are using VPN, always check the terms and rules of the provider. Avoid random VPN Services.

Using a VPN will not keep your browsing habits anonymous, nor will it add additional security to non-secure (HTTP) traffic.
Recommended is to encrypt your data/files always before uploading them to cloud with tools like Cryptomator.
Always use unique and strong passwords for each of your accounts.
Use awarded open source Password Managers like KeePass or KeePassXC for Desktop and KeePassDX for Android to manage your passwords and have them with you safe, encrypted and secure. Must be noted you can use the same database file between these programs.
Always enable 2 Step Authentication wherever is available for your accounts.
You can use apps like Aegis Authenticator.
Do not open or click on links attached in unknown emails you may get. Always check the adress of the email and verify it's legit from the official source.
Create and use "burned" email for accounts/sites you have concerns but you definitely want to try them. Do not use your personal or business email.

2. Unlock Bootloader. [Read the Unlock Bootloader Guide above]
3. Download: [You can find everything in my Collection]
Custom Recovery of your choice.
Custom ROM of your choice
GApps (be sure you have selected Platform: ARMx64 and the proper Android version of the ROM you are going to flash) if the ROM you are going to flash does not include. [Optional]
Magisk Root Solution [Optional]
Disable Force Encryption [Optional]
4. Move all these files in one folder to your Internal Storage or to External SDCard if you have.
5. Install Custom Recovery. [Read the Install Custom Recovery Guide above]
6. Reboot to Recovery Power Button + Volume Up (+)
7. Installation:
Steps without external SDCard:
Select Wipe > Advanced Wipe
Select Dalvik / ART Cache, System, Data, Vendor, Cache and then Swipe to Wipe.
Flash ROM > GApps [Optional] > Magisk [Optional] > DFE [Optional - Not Recommended]
Go back and select Wipe > Format Data > type yes [All your data into Internal Storage will be lost]
Reboot Enjoy!
Steps with external SDCard:
go to Advanced > File Manager > External_SD and delete all folders in ur ext sd card (For example you should delete: Android, .android_secure, LOST.DIR, DCIM, etc) except your personal files/folders and the folder with your custom ROM/Gapps/Magisk/DFE you want to flash.
Each app on your phone with the WRITE_EXTERNAL_STORAGE permission may create files or folders in ur sdcard. Most of these folders have once been created by one of these apps and many of them may be deleted with a few exceptions (e.g. Android, .data, .android_secure, these contain important system or app data like a game's downloaded content):
.android_secure: apps installed and then moved to sdcard
Android: app data/cache
data: app data
.estrongs: ES file manager
LOST.DIR: sort of trash folder (collects recovered files after phone crashes)
DCIM: phone gallery's photos and previews
OTA-update: Over The Air update service
ppy_cross: an unknown third-party app's data.
So I recommend to delete them so you can put your phone/sdcard in a clean state and is guaranteed to be able to re-create these folders.
Select Advanced Wipe
Select Dalvik / ART Cache, System, Data, Internal Storage, Vendor, Cache and then Swipe to Wipe. [All your data into Internal Storage will be lost]
Flash ROM > GApps [Optional] > Magisk [Optional] > DFE [Optional - Not Recommended]
Go back and select Wipe > Format Data > type yes [All your data into Internal Storage will be lost]
Reboot Enjoy!
DIRTY INSTALL YOUR CUSTOM ROM
Note: Before you start flashing, keep in mind the ROM you dirty flashing MUST be the same with the one you have already installed.
1. Make a full nandroid backup, just in case something goes wrong. You can use TWRP to do that. (TWRP > Backup > Select everything) [Optional]
2. Remove all Magisk modules. [Optional]
3. Reboot to TWRP and Wipe Dalvik / ART Cache, System, Vendor, Cache.
4. Flash the ROM > GApps [Optional] > Magisk [Optional] > DFE [Optional - Not Recommended]
5. Reboot and Enjoy!
I've skipped some explanations, because if you are going to dirty flash, you already know for example how to boot to TWRP.
