Impossible to encrypt Mi5 - xiaomi.eu rom

Hi,
for the installation of the xiaomi.eu rom I formatted data partition, losing the marshmallow default encryption.
Now I installed xiaomi.eu 8.0.10.0 rom and I'm trying to re-encrypt my device through setting --> additional setting --> privacy --> encrypt device.
After I choose to encrypt it, a black screen with green android appears for just few seconds, and then the phone reboot to system.
What I've have to do in order to re-enable encryption?
Thanks a lot,
Angelo

Same problem on 8.0.12.0 rom

I don't think encryption would work on custom MIUI builds, since the devs needs to disable all flags related to it. My guess is that it's kernel removes the forceencrypt flag and does not add the encriptable flag as replacement, so the kernel don't accept that volume as an encryptable one.
I believe the best way on this case would be extracting the original kernel from a unmodified miui version and changing those values yourself to see if it works.

TWRP, System writing, Supersu, Impossible?

I have had my fair share of problems modifying android before but I have never had a phone flat out lie to me and say an operation was successful and actually nothing happened at all.
Have had my nexus 6 for a year or so now. Have had minor issues rooting / modifying marshmallow in the past but I figured out it was all caused by the system partition having basically 0 free space. Made a huge mistake and installed to the latest 7.0 OTA. Wanted to simply enable tethering and edit the thermal config to not shut cores down. Should be as simple as pulling the files, editing them, pushing them back to the phone in twrp with the system partition mounted and thats the end of it right? Wrong.
First of all twrp 3.0.2 refuses to let me touch the system partition without some giant prompt about how its going to make itself stick and offer to root the phone. Simple enough I have seen it in previous versions I say yes as usual except twrp proceedes to immediately spew a bunch of superuser files that do nothing throughout the system partition without asking me if I want root. Dumb but whatever. I mount /system as read write and I go edit and replace my two files like usual (build.prop and thermal config). No matter if I ADB push or use twrps built in file manager it claims the file replacement is successful. Reboot into android and not only have both files not been touched (Verified by adb pull) but the recovery gets overwritten with the factory recovery anyways. (NEVER had issues with twrp sticking on marshmallow. Now after every reboot it gets wiped out)
Second of all if I select yes to twrp mounting system as writable and it does its spewing as I mentioned before then installing SuperSU instantly causes the phone to not boot. Rewrite the boot.img to factory and it boots fine OR Rewrite the clean factory system image and the SuperSU boot works fine. But modifying /system with twrp and then running supersu at the same time is a no go. TWRP is obviously doing something stupid to system that pisses off supersu so undoing twrps mess or uninstalling supersu makes it bootable again.
I dont even want root! Everyone is claiming you need to run "settings put global tether_dun_required 0" as root along with adding the usual "net.tethering.noprovisioning=true" in the build.prop to get native tethering working again! On 6.X only the build.prop edit was needed to get it working.
So long story short. I just want native tethering to work and to tweak my /system/etc/thermal-engine-shamu.conf . Is there anyone here who has done this successfully on nougat? I feel like its all twrps fault but im far too tired and frustrated to try another version tonight.

You must be running an old version of TWRP. Update to the latest, as the latest no longer offers to root your device for you. The version of superuser included was ancient and caused the device to bootloop.
As to TWRP being overwritten Android 7.0 I believe does that on a stock system. If I recall, there is a script that needs to be modified to prevent it.

It's stated in the op he's using twrp 3.0.2.

I misread his post then. I wonder if perhaps he is running TWRP via fastboot instead of installing it.

[GUIDE] OOS v4.0.3 ---> FLASH & ROOT STOCK -OR- CUSTOM ROM WITH EASE & CORRECTLY

[GUIDE] OOS v4.0.3 ---> FLASH & ROOT STOCK -OR- CUSTOM ROM WITH EASE & CORRECTLY
If you think that I need to add more information to this guide, please post your request. I'm not able to guess what you want from me to add to this guide.
Thank you!
INTRODUCTION:
This guide is mainly for users who tried flashing OxygenOS v4.x.x the easy and short way (like in post #9 in this thread), which had issues in the process.
I covered the most common issues with flashing OOS v4.x.x in this guide. However, you can use this guide to flash OxygenOS (latest Stable and Beta versions)
and root them OR flash your custom ROM. Just follow the instructions.
Now, you ask “why I decided to write this guide?”. Well here’s my story:
I had FreedomOS v1.7 with Google apps installed (including Dialer and Contacts from OpenGApps), encrypted, official twrp (v3.0.2-1), Xposed (v3.1.1), framework (v87),
AdAway v3.2, YouTube AdAway and SuperSU v2.79 (stable). Also, stock kernel, no Dolby ATMOS or A.R.I.S.E apps.
So, when OOS v4.0 came out, I waited for FreedomOS v2.0 to come out too. Once it did, I downloaded the ROM, OpenGApps, modified twrp .28 and started
the flashing process (I backed up my data first).
First, I flashed twrp .28 (had no problems booting into it), and clean flashed FOS v2.0. I selected “Yes” in “Pin/Pattern backup in data partition”, so I wouldn’t have issues with encryption. I selected the regular apps (for OOS to work properly) and installed the OS.
When it was done, I rebooted the device to the OS. I was confused with the new “dm-verity” message popping from nowhere, but the OS booted successfully.
When I rebooted to the twrp (to install OpenGApps), it asked for a password. I couldn’t enter the right password, because it wouldn’t accept any and it blocked
my access to my internal storage.
I started panicking, looking for answers, and I was afraid that I bricked my phone. However, after some research, I calmed down. I realized that my bootloader was still working and could roll back to OOS v3.2.8 (with stock recovery), which I did. From there I flashed FOS v1.7 and waited for more information about the new Nougat update for OnePlus 3.
Now, I’m using Stock OygenOS v4.0.3 with Stock Kernel (see FAQ #16) and so far, no issues (no dm-verity message or password upon entering modified twrp).
I tried to repeat the dm-verity issue and fixed it (see FAQ #6). I was so frustrated that no one posted a proper guide on how to fix these issues, or they were too advanced. I didn’t want to mess around with the core of the system too much. Therefore, I decided to post a simple-to-follow guide.
DISCLAIMER & IMPORTANT:
I am not responsible for any damages done by this guide. You are tinkering with your phone and held responsible for that. This is not an advanced guide. Therefore, I will refer you to the advanced guides when needed. Furthermore, this guide is based on the issues that I and other users encountered while
flashing OOS v4.x.x ------------>***BACK UP PERSONAL DATA BEFORE PROCEEDING ANY FURTHER***
This guide is intended for owners of OnePlus 3. But, after some poking in OnePlus 3T forums, you can use this guide. The only differences the OnePlus 3T
have are a newer processor, newer front camera and a different color from OnePlus 3. Make sure to use the appropriate tools (Stock recovery, TWRP,
OxygenOS v4.0.3, etc.) for OnePlus 3T. Again, I will not be responsible for any damages caused by this guide.
Please follow this guide to get rid of: dm-verity, encrypted twrp, encrypt or decrypt your device (as OnePlus 3 comes encrypted by default), change your file system from EXT4 to F2FS (vice versa as well). Also, flash a Marshmallow or Nougat Stock OOS (Stable or Beta versions), root them OR unroot your device, OR flash a custom ROM.
As far as I know, tested and read in forums, Android v6.0.1 (OxygenOS v3.x.x) supports only EXT4 file system, and Android v7.0 (OxygenOS v4.x.x) supports both EXT4 and F2FS file systems. However, F2FS is recommended for Android v7.0 (OxygenOS v4.x.x). When you perform, a full factory reset in OxygenOS v4.x.x, the file system changes from EXT4 to F2FS. ONLY “Data (userdata)” is affected by this. If you want to go back to Marshmallow, OxygenOS v3.x.x will change your file system from F2FS to EXT4 when you sideload it.
OxygenOS v4.0.3 still comes with some issues, bugs, and some rooting services are not fully supported yet (i.e. Xposed for Nougat). Luckily, OnePlus released kernel sources of Nougat, and we need to wait a little longer for Xposed and other rooting services to be supported. Therefore, I advise staying away from it,
for a little while, until those issues are fixed, and new ones don’t pop up. Also, until rooting apps are fully supported. Follow OnePlus community forums and
XDA forums for updates, troubleshooting, and solutions for your issues. MAKE SURE TO BACK UP YOUR PERSONAL DATA, time to time.
Before posting questions or issues or requests, check FAQ and posts in this thread. Thank You!

[I][SIZE="4"][B] * I'LL BE USING OOS v4.0.3, OFFICIAL UNRELEASED TWRP v3.0.4-1 AND FreedomOS
v2.3 AS AN EXAMPLE FOR THIS GUIDE. OTHER VERSIONS OF OOS AND TWRP
(PROVIDED) ARE APPLICABLE TO BE USED IN THE GUIDE (ONLY WHAT I TESTED).

* If you do have dm-verity issue, file system change issue or password upon
entering TWRP, then continue to Section A (DM-VERITY).[/I][/COLOR]
[/B][/I][/SIZE]
A - PROCEDURE (DM-VERITY):
Code:
[I][SIZE="4"][CENTER][B]***** Check FAQ #5 before proceeding any further! *****[/B][/CENTER][/I][/SIZE]
Boot to bootloader by holding Volume Up and Power buttons.
Connect the phone to the computer via USB cable.
Go to your ADB folder (for me it is C:\Android\). Press “Shift” and click the right mouse button. Click on “Open command window here”.
In the console write “fastboot devices” to see if your computer recognizes your OnePlus 3.
When you could see that your device is recognized, write “fastboot flash recovery recovery_op3.img” to flash Stock Recovery of OxygenOS.
Disconnect the device, press volume up once, then press the power button once to turn off the phone.
Boot into recovery by holding Volume Down (-) and Power button down for a few of seconds.
Now, for some people, it will ask a password. If not, continue to #9 and ignore #8. If it asks you to enter a password to decrypt your data, choose “Forgot password” and let it erase all your data and let it reboot. (MAKE SURE YOU BACKED UP YOUR PERSONAL DATA BEFOREHAND). Most likely, it will reboot to the OS, so boot it to recovery again. Go to #10.
For those who doesn’t have to enter a password, press “English”. Press “Wipe data and cache” > “Erase everything (Music, pics, etc.)” > “This cannot be undone, continue?”. Moreover, let it wipe your data. Most likely, it will reboot to the OS, so boot it to recovery again. Go to #10.
Code:
[CENTER][I][SIZE="4"][B]AT THIS POINT IF YOU HAD DM-VERITY ERROR/ISSUE, IT SHOULD BE FIXED AND GONE.
IF IT STILL APPEARS, DON'T WORRY IT WILL BE GONE AFTER #12
IT CAME BACK TO ME ONE MORE TIME, BUT I GOT IT FIXED.
***** Check FAQ #6 for more information *****[/B][/I][/SIZE][/CENTER]
Select “English” > “Install from ADB” > “Ok”. Connect your phone to your computer. Go to your ADB folder (for me it is C:\Android\). Press “Shift” and click the right mouse button. Click on “Open command window here”.
In the console, write “adb devices” to see if your computer recognizes your OnePlus 3.
When you could see that your device is recognized, write “adb sideload OnePlus3Oxygen_16_OTA_041_all_1702081756_0f1e56a75f.zip”
to flash OxygenOS v4.0.3. (See FAQ #4 and #17 if you have issues)
Reboot and you have OxygenOS v4.0.3!
Sign-in into your Google account and Download the “DiskInfo” app from the Play Store. Launch it, and press “Data (userdata)”. You should see:
- Encrypted: yes
- Decrypted block device: /dev/block/dm-1
- Mount point: /data
- File system: f2fs
A. If you see that it is in F2FS file system format, proceed to Section C (FLASHING YOUR CUSTOM ROM) OR Section D (FLASHING AND ROOTING STOCK OOS OR UNROOT).
B. However, for some people (for some reason) it does not happen. You would see that your file system format (for userdata) is still on EXT4. Don’t be frustrated. A little bit more work needed to be done. Therefore, go to Section B (CHANGING FILE SYSTEM FORMAT AND ENCRYPTING OR DECRYPTING YOUR DEVICE). It will solve that problem.
Code:
[I][SIZE="4"]* Your phone needs to be encrypted by default. It comes like that from the
manufacturer. See the following links:

[/I][/SIZE]
B - PROCEDURE (CHANGING FILE SYSTEM FORMAT AND ENCRYPTING OR DECRYPTING YOUR DEVICE):
Go to: Settings > Security & fingerprint > Encryption (located at the bottom). Make sure it says “Encrypt phone (Encrypted)”. To make sure
you will need to do a factory reset.
Now go to: Settings > Backup & reset > Factory data reset. In “Optional” select “Erase internal storage” and press “RESET PHONE”. Confirm by pressing “ERASE EVERYTHING”.
It will reboot to Stock Recovery and wipe your data. When it’s done, it will reboot to the OS.
Again, download the “DiskInfo” app from the Play Store. Launch it, press “Data (userdata)”. Now you should see (it wouldn’t show “Encrypted: yes” at all):
- Mount point: /data
- File system: f2fs
Now go to: Settings > Security & fingerprint > Encryption (located at the bottom). Make sure it says “Encrypt phone” and that you can press it. (DON’T ENCRYPT YOUR PHONE WITH THAT OPTION)
Now you successfully changed your file system to F2FS and decrypted your phone!
Code:
[I][SIZE="4"] * With Official TWRP v3.0.3-0 and modified TWRP v3.0.3-x v16 (from [user=3873953]@eng.stk[/user])
you are able to use the phone in encrypted mode, password request at
boot up and with Stock or rooted OOS v4.0.3 (Also, I tested it myself).
* Therefore, I will ask you to encrypt the phone back again. Proceed with
the following instructions:
[CENTER]***** Check FAQ #9 for more information *****[/CENTER][/I][/SIZE]
Reboot to Stock recovery v2.0
Select “English” > “Install from ADB” > “Ok”. Connect your phone to your computer. Go to your ADB folder (for me it is C:\Android\). Press “Shift” and click the right mouse button. Click on “Open command window here”.
In the console, write “adb devices” to see if your computer recognizes your OnePlus 3.
When you could see that your device is recognized, write “adb sideload OnePlus3Oxygen_16_OTA_041_all_1702081756_0f1e56a75f.zip”
to flash Oxygen OS v4.0.3. (See FAQ #4 and #17 if you have issues)
Reboot your device. Now you back to being encrypted and “userdata” was changed successfully to F2FS file format on Stock Oxygen OS v4.0.3!
Go to Section C (FLASHING YOUR CUSTOM ROM) to properly flash your custom ROM. *** IT’S YOUR CHOICE ***
OR Go to Section D (FLASHING AND ROOTING STOCK OOS OR UNROOT) to remain in stock, root or unroot. *** IT’S YOUR CHOICE ***
C - PROCEDURE (FLASHING YOUR CUSTOM ROM):
Boot to bootloader by holding Volume Up and Power buttons.
Connect the phone to the computer via USB cable.
Go to your ADB folder (for me it is C:\Android\). Press “Shift” and click the right mouse button. Click on “Open command window here”.
In the console write “fastboot devices” to see if your computer recognizes your OnePlus 3.
When you could see that your device is recognized, write “fastboot flash recovery twrp-3.0.4-1-oneplus3.img” to flash Official Unreleased TWRP v3.0.4-1.
Disconnect the device, press volume up once, then press the power button once to turn off the phone.
Boot into the TWRP by holding Volume Down (-) and Power button down for a few of seconds.
It takes a little bit more time to boot to blu_spark’s, Official and Unofficial TWRPs. Be patient.
Code:
[I][SIZE="4"] * The “PASSWORD UPON ENTERING TWRP” should not be an issue any longer (only
if you followed the whole guide). It is caused by the TWRP being modified
(has an issue with encryption), not being officially released and fully
supported for the Nougat update. Versions “.28”, “.22” and “.19” are known
for that issue. Therefore, DO NOT USE THEM. If one of them works for
you, then use it at your own risk.

FAQ (Q&A):​
Q: I can’t boot into TWRP! What to do?
A: Try using the previous TWRP or Stock Recovery.
[*]Q: I can’t boot into the OS! What to do?
A: Most likely some of the OS files are damaged or executed incorrectly. Try flashing or sideloading the OS again.
[*]Q: I can’t transfer files to my OP3 after wiping Internal storage OR Data folder/s in TWRP! What to do?
A: Don’t panic. Reboot to TWRP. It will create a folder so you can transfer files again.
[*]Q: I got an error sideloading the OS. Why is that?
A: Sometimes it occurs when the USB cable is wiggled side to side (the process stops at 92% with an error). Try again without touching
or moving the USB cable and the phone. Alternatively, it could be that USB debug is not enabled (not sure about that).
[*]Q: Is there an alternative way to get rid of dm-verity issue?
A: One simple command-line (enable) in bootloader can solve it. Check this post: https://forum.xda-developers.com/showpost.php?p=70698410&postcount=112
Otherwise, check this thread: https://forum.xda-developers.com/oneplus-3/how-to/fix-device-mapper-verity-simple-trick-t3530685 This guide uses the .28 twrp
(NOT RECOMMENDED, BUT USE TWRP FROM @eng.stk) to use Stock Recovery, which I think is a bit more complex.
OR: https://forum.xda-developers.com/showpost.php?p=70415499&postcount=33
My guide uses only bootloader, Stock Recovery and TWRP from @eng.stk. Either way, they are the same guides.
[*]Q: The "dm-verity issue" came back after flashing OTA of stock OOS v4.0.2 via the TWRP! What to do?
A: Simply follow "Section A" instructions until #13. After you sideloaded the OTA it will be gone. It happened the second time when I tried to
flash the OTA via TWRP. Therefore, don't flash OTA of stock OOS v4.x.x via TWRPs. Only via Stock Recovery v2.0
I got it fixed only after sideloading the OTA via Stock Recovery v2.0 (Check post #29 for more information)
If it still doesn't work check this thread and read it thoroughly: https://forum.xda-developers.com/oneplus-3/development/recovery-official-twrp-oneplus-3-t3539129
For more information, read FAQ #12
[*]Q: Your guide to change file format doesn’t work, OR I want to change “Cache” and “System” to F2FS as well. What to do?
A: Simply go to this link and at your own risk: https://forum.xda-developers.com/oneplus-one/general/guide-formatting-ext4-to-f2fs-losing-t3352116
Furthermore, @cpt.macp mentioed in post #34 in this thread that "/system and /cache need not to be f2fs . Oneplus Supports only /data
as f2fs and nothing else ."
[*]Q: I can’t log in into Snapchat after a clean flash of my desired custom ROM or after rooting my device. How to fix this?
A: I had the same issue, and it doesn’t occur to everybody. Before DIRTY flashing (wiping System, Cache and Dalvik only) the custom ROM
-OR- rooting your device, install Snapchat and log into it (on stock OOS v4.x.x). It might be a SuperSU (root) issue with Snapchat
(they enforced their security with rooted devices).
Also, OnePlus 3 has an issue with on-screen navigation bar. So, disable it in the "Buttons" menu until OnePlus fixes the glitch/bug.
[*]Q: Why did you choose TWRP v15 from @eng.stk -OR- Official TWRP v3.0.3-0 -OR- Unofficial TWRP v3.0.3-0?
A: They all work with the phone being encrypted, requesting a password on bootup to the OS and support F2FS file system.
.28 – had issues with encryption and F2FS file system, but for some users it works wonders.
.22 and .23 – I did not test, but I have read that .23 worked (decrypted).
.19 – Tested and solved the password issue, but had a mouse pointer in the middle of the TWRP (wasn’t a big deal). Worked in decrypted mode.
P.S. The official TWRP has issues with the name of the device. If you encounter those issues, then let the developer of the ROM
you're using know about it. So, he could fix it (it's a small fix). OR use TWRP v15 from @eng.stk. Unofficial TWRP is to be used
with LineageOS 14.1 & Experience v10 ROMs. Also, here is the reason why: https://forum.xda-developers.com/showpost.php?p=70593986&postcount=53
Also, Official TWRP v3.0.2-1 doesn't support Nougat. Therefore, you won't be able to boot to this TWRP. Don't use it for Nougat.
[*]Q: I am experiencing a battery drain. Why?
A: Facebook was the main issue for that, but it is now fixed (some users said that it still exists). I use Freedom OS v2.2 and no
issues so far with the battery. I got 5 hours SOT (Screen On Time) with 45% left (on the first day), and 5½ hours SOT with 26%
battery left (on the second day). Now, I think the OS is balanced because I get almost 8 hours of SOT. Try looking for a solution
in the forums. Also, disable mobile data when using WIFI and vise versa. Furthermore, battery life may vary with the applications
you use on a daily basis, screen brightness, how much and long you touch the screen, etc. (See the attached thumbnails)
[*]Q: I am experiencing issues with the Play Store app (It’s stuck on downloading). Is there a fix?
A: When you first launch it, it tries to update itself. It will crash 1-2 times. After that, everything works just fine. Also, uninstall or don’t
install Truecaller app (well known to cause this issue). It was fixed in OOS v4.0.2, but some users still experience this issue.
In addition, if nothing works, then try uninstalling the Play Store app and reinstall it via OpenGApps. For those who are not rooted,
try finding the Play Store app via the web (install it under your own risk, as I'm not responsible for the damages).
[*]Q: Why do you use stock recovery to sideload the OS?
A: First of all, you’re going to sideload OTA of Oxygen OS, which you can’t flash in the TWRP (some people can and you might get dm-verity
issue). Secondly, the stock recovery is simple and easy to use. Thirdly, If you flash the OTA from the official TWRP, you will get a dm-verity
message. Besides, OnePlus provided only with "OTA" zips and not "signed flashable" zips.

[*]Q: What if I want to go back using Oxygen OS v3.2.8 (Andriod v6.0.1) or custom ROMs based on it?
A: Simply instead of using Stock Oxygen OS v4.0.2 OTA in this guide, use Stock Oxygen OS v3.2.8 OTA.
It will bring back EXT4 file system and you can use Xposed.
[*]Q: After clean flashing my Custom ROM in TWRP, I get the following message: "No OS Installed. You Sure You Want
To Reboot". What to do?
A: Try dirty flashing your Custom ROM. (Source: https://forum.xda-developers.com/showpost.php?p=70622460&postcount=5291)
[*]Q: Android System WebView is disabled in the Play Store. When I try to enable it, it won't do anything. Unless I tap
it rapidly and it's still in disabled mode. What to do?
A: No need to worry here. It is normal due to Chrome being the new WebView in Android Nougat.
(Sources: http://www.androidpolice.com/2016/07/20/google-explains-chrome-will-become-webview-android-7-0/ AND https://productforums.google.com/forum/#!topic/nexus/Ni35XW6eRR0

[*]Q: Should I flash a custom Kernel (ElementalX or Blu_spark) on a custom ROM?
A: You can, but you might have CPUs being on max load and overheating issues (it's not caused by the kernel itself).
They work best, and only, if you have stock OOS v4.0.2 installed and rooted with SuperSU v2.79 Stable. Yes, for some
users the custom kernels work. But, for some they won't, due to firmware issues. You can try them on your Custom
ROM, but it's not guaranteed to work. The developers of FreedomOS and ExperienceOS solved this issue.
**Some users found a solution by setting SELinux to Permissive mode instead of Enforced.
I do not recommend setting your SELinux in Permissive mode! (as well as the developer of ElementalX)!

[*]Q: I'm getting the error (cannot read "image.zip") when trying to sideload Stock OOS. Why and how to fix this?
A: For some reason, the thread added a space in the OOS file name. If you copy the file name for Stock OOS v4.0.2 from this thread,
make sure it doesn't have spaces in it (-OR- in any other file -OR- in the console).
** Also, make sure to enable USB Debugging in Developer Options.
** Follow these guidelines separately (if the first one doesn't work, use the second or third guideline):
Reinstall OnePlus Drivers using the attached zip (OnePlus_USB_Drivers_Setup.zip) and try again. In addition,
make sure your file name is not ending with ".zip.zip" or written like that in the console.
Bootup to your OS and connect the phone to the computer (make sure to choose transfer files mode).
Copy Stock OOS v4.0.2 OTA zip to the device and reboot to recovery. Select "Install from Internal Storage",
look for the OTA file and install it.

Very easy to follow guide. I ended up at B8 "Now you successfully changed your file system to F2FS and decrypted your phone!". I would like my phone to be encrypted, but if I do it through the OS, TWRP does not accept my password for the data partition?

Hi, i have oxygen os 4.0.1 rooted and twrp v11 bluspark...But its normal when i deletet some file i dont see immeditely the free space unti i reboot the phone...this happened sometimes and sometimes not...Its a bug?

I have flash as you post, when flash done i check file system by diskinfo, it displayed "userdata not mounted". how do i fix it. plz help me. thank you very much.

Lol this is just what I did:
1. Flash latest @eng.stk TWRP, swipe to allow modifications
2. Wipe system, data, cache
3. Install 1.4GB 4.0.1 zip
4. Wipe dalvik and cache
5. On Mount, check Mount /system as read-only
6. Reboot to system
You now have stock 4.0.1 system, kernel, and recovery.
7. Boot to recovery. TWRP is overwritten by the OOS 4.0.1 recovery.
8. Wipe everything. /data is now f2fs
Optional: flash TWRP, swipe to allow modifications, and do not check Mount /system as read-only to keep it.
No issues at all.

Thank you! Solved my problem with Dm-Verity. Do you think, for the future *4.0.2* update or whatever number will be, that we will be able to flash OTA via TWRP or we'll need stock recovery? Only full zip with TWRP?

You might want to change that TWRP v12 back to v11. Eng.stk found some issues with v12 and pulled it.
And great guide BTW ?

Seems like "sideload"ing OOS v4.0.1 didn't change your file system, correct?
I would recommend to start over. When you are done B7, "sideload" OOS v4.0.1 to encrypt the device again. After that's done, continue to section C.

I think it's not normal and you should see an immediate change in your free space.
I couldn't find any information about that.
Your best options are to follow this guide (if you didn't already) AND/OR post this issue in OnePlus 3 community forums.

Did you "sideload" stock OOS in stock recovery OR flash custom ROM via TWRP (I think this one)?
Also, where did you stop (section and number)?

Yes, that might be the easy way when you have no issues. But, this guide deals with common issues (dm-verity, twrp password etc.) users face when they tried to update to OOS v4.0.x
If you'll face these issues in the future, you'll know where to find the related guide to fix them.

You could flash OTA via TWRP (full size zip and not the small 40mb zip), but I'm afraid that it might "break your root" (you wouldn't have it anymore). It can be fixed by flashing SuperSU.
Technically, you could dirty flash (wipe System, Cache and Dalvik only) the new OTA. If you would have issues after dirty flashing, post your bugs/issues, and most likely you would have to clean flash the OTA.
Give it a try (backup your personal data and dirty flash) or wait for user feedback on the new OTA.

I wish I had found this guide before but never mind. I was following original rooting guide by Naman on my OP3 running stock OOS 4.0.1. I used twrp v28 of blue spark and as observed by many I ended up in encryption issues and couldn't take nandroid backup so I didn't proceed.
Now, it seems it has been fixed with latest twrp (v11) by blue spark. My /data partition is already f2fs and cache is /ext4.
What steps should I follow to get back correct recovery and hopefully root as well? I am hoping that I do not need to sideload 4.0.1.

I've had all of the issues in this guide. So, I decided to post one because nobody posted in-depth guide to deal with OOS v4.0.1
Also, TWRP v28 has issues with encryption being on and F2FS issues too. It caused all of my problems. I was a bit lucky to find TWRP v19 (had a mouse pointer in the middle of the TWRP, no big deal). It worked with EXT4 and F2FS file systems but wasn't perfect due to working only in decrypted mode.
It seems like you don't have any issues. Am I correct? (No password request in TWRP, dm-verity message)
If you don't, go to section "C - PROCEDURE (FLASHING YOUR CUSTOM ROM)".
About file system - leave it be. Only "/data" should be F2FS, "/Cache" and "/System" as EXT4. To much work to change them to F2FS and TWRP formats them to EXT4 when you wipe them.

[OOS][Stable][OP6T Global][OP6T Tmobile] Oneplus 6T stable OOS guide thread

OOS stable for Oneplus 6T Global ​
This thread is an attempt to make things clean for OP6T users.
It will contain latest zip links for OOS stable.
It will contain a brief guide on how to root, install TWRP , how to update with or without those elements.
6T global edition is supported by thread readers and me, and T Mobile converted specific concerns will be handled by community under the supervision of @Scott, thanks to him for the help.
It will not contain basics like ADB and Fastboot connection with a computer. Experiment, read, there are many and many tutorials on the internet for that. Don’t forget there is a world outside XDA and that you can perform a search on any search engine to grab information.
It will not cover by decision the ‘patching boot.img’ method for gaining root. It’s not necessary to use it when we have a working TWRP and Fastboot. If you want to try it search on the internet about ‘extracting boot.img from payload.bin’ and then use Magisk Manager to patch it.
Please NO discussion about: Magisk itself, custom kernels, debloating (whatever method you want to use), custom ROMS… Only STOCK STABLE OOS.
If you just want to flash custom kernels, no need to have TWRP, Ex Kernel Manager and Franco Kernel Manager for example can take care of that (see Play Store to grab those apps), and backup your stock kernel.
ALWAYS USE LATEST VERSIONS of the different tools used. Don’t ask for help if you’re using 6 months old TWRP or Magisk. Update it first.
First a bit of what I have understood about our phone, and its main specificity, i.e A/B slots.
A/B slots, what else ?​
This structure is meant to enable to have two different versions of the SAME ROM, one slot will contain the previous version of the ROM, the other slot will contain the updated one. If you are on slot A and running 10.3.0, the update process will lead to have 10.3.0 on slot A and 10.3.1 on slot B. On next boot the bootloader will automatically boot updated one (i.e slot B will be flagged as the active one). In case of issues during boot process the bootloader will switch the active slot back to the ‘old’ version(here slot A) that was booting fine.
This means that IT’S NOT a dual boot feature!! If you want to run a custom ROM it’s better to have the same custom ROM on both slots and not a mix of OOS and custom ROM. But that’s already OT so let’s stay focus, each custom ROM should provide clear instructions about that.
Having a slot phone means that there is no Recovery partition. So if you ‘fastboot flash boot twrp.img’ it will overwrite your boot partition and thus the ROM kernel and can lead to issues. The .img file is only meant to be temporarly booted. Recovery (stock or TWRP) is a part of the boot ramdisk.
Some simple facts about slots and flashing in TWRP:
Flashing a whole ROM (OOS for example) will automatically flash it to the currently inactive slot and switch it to be the active one (that works also with stock recovery, when performing a ‘local update’)
Flashing a ROM overwrites completely the boot partition (in recent Android versions, flashing process is using partition RAW images and not files like it was before): that means that TWRP and Magisk (if present) will be ERASED.
Flashing TWRP installer will flash it AUTOMATICALLY ON BOTH SLOTS (and will erase Magisk if present)
Magisk (and GAPPS but it only applies to custom ROMs), when flashed with TWRP is only flashed in ACTIVE slot. That’s why you must REBOOT to recovery BEFORE flashing Magisk to have it installed on the active updated slot. And that explains why you must flash it last.
That said, if you stay on OOS, YOU DON’T care about slots, just remember those basics to understand why you have to respect some steps, and let the recovery take care of slots. Messing manually with them results often in soft bricks

If the above doesn’t work anymore just let me know I’ll find something else.
FYI you can still go to Oneplus website but they take time to update it to latest version… And there is no archives.

ROOTING (+/- TWRP)​
Magisk zip is to be found here
TWRP latest .img and installer are to be found here
Don’t use all-in-one tools, you’re a grown up person you can to it by yourself. Yes you can.
If you're not rooted and run an OOS version older than 10.3.1, update your phone normally to latest OOS stable version then do as below
If you’re not rooted and running 10.3.1 or higher, those are the simplest steps to gain root.
Unlock your bootloader (will wipe everything…): “fastboot oem unlock” from a computer (see beginning of OP to know why I don’t detail this) with phone in fastboot mode
Grab latest Magisk zip on your phone and latest TWRP .img on your computer (AND TWRP installer .zip on your phone if you want to install TWRP permanently). Boot in fastboot mode your phone.
Then :
“fastboot boot twrp_latest.img” (adapt to the name and path of your twrp file)
within TWRP, flash TWRP installer .zip if you want to keep TWRP
flash Magisk zip (always AFTER flashing TWRP)
Reboot
(you can theoretically use the TWRP feature ‘install recovery ramdisk’ to avoid flashing twrp installer but never tested)
Note: please STOP using blue_spark TWRP!!! Support for OP6T has been stopped long time ago, only OP6 twrp is still actively supported by eng.stk (errors are mandatory if you flash it on 6t). I even see people that use a 3.2.x version of blue_spark...

UPDATING WITHOUT ROOT​
If your bootloader is locked (meaning no root no TWRP, factory state), the update process is trivial, OOS (or Oxygen Updater if you use it) will grab a patch file (around 100MB max usually) and will apply it and will ask you to reboot. Everybody should be able to do this as it’s the normal way every phone on earth updates itself… If major changes are present sometimes you’ll have the whole ROM file. It doesn’t matter anyway it leads to the same destination.
If your bootloader is unlocked but without root, the only difference is that OOS (or Oxygen Updater) will download the WHOLE ROM (around 1.8GB) and will apply it then ask for rebooting
UPDATING WITH ROOT (+/- TWRP)​
Whole ROM update is mandatory. You can wait for System Update to download it or grab manually the zip file or use Oxygen updater. You then go in Settings > System > System Update > clic on the upper right cogwheel then choose ‘Local Update’ and select the zip file (If you download the OTA .zip file manually you must place it in the root of user data, like /data/media/0/ i.e the user internal storage, or eventually in the .OTA folder if there's one. If you use Oxygen Updater or System automatic donwload it will be right placed).
The following update method is the preferred one (even if you have TWRP, recommended by some TWRP devs) due to frequent changes in partitions by OnePlus
apply the ROM update via Settings > System > System Update > Local Update
DON’T REBOOT
Open Magisk Manager
[If you have TWRP, go in Modules menu, clic on ‘+’ and choose latest TWRP installer zip file on your phone. Don’t use Retention A/B Script Magisk Module I had issues with it] [then stay in Magisk Manager and do the next step]
On main screen of the app clic on ‘install’ next to Magisk paragraph
On the pop up menu confirm ’Install’
On the next pop up menu clic on the last entry: install on inactive slot (after OTA update)
Then only reboot.
The order can be changed (the most important thing to preserve is Magisk, TWRP is easy to flash back):
Update without taking care of TWRP, just Magisk part ("install to other slot after OTA thing")
Once rebooted to updated system, flash TWRP as a module with Magisk Manager
Install Magisk again using Magisk Manager ("direct install" option)
There are infinite debates about uninstalling or not Magisk Modules before updating. Most of the times nothing to touch, sometimes there could be issues, instead of uninstalling perhaps just inactivate them by precaution before updating.
Note: If you are rooted and run an OOS version older than 10.3.1, the above method should work, but you can also update your ROM to latest stable without taking care of root/TWRP and then root again as described in post #2
If you want to try TWRP way:
Reboot to TWRP
Flash OOS update
Flash TWRP installer
Reboot to Recovery
Flash Magisk
Reboot System
IF YOU ARE INTO A SOFT BRICK​
Don't forget the Vol+/Vol-/Power_button combo that can save you from a non responding phone...
If you can boot in fastboot mode, flash the stock ROM with fastboot. A little trick is to edit the flash-all-partitions**.bat and remove ‘-w’ (-w means that the partition will be wiped before flashing) from the script, it will prevent personal data wipe. Or flash manually all partitions one by one, without ‘-w’ flag evidently. Some partitions can’t be flashed with fastboot, for that once booted back to OOS, download and install by ‘local update’ method the same ROM version you’ve just restored with fastboot (see the linked thread to know why, emojis issues for example sometimes).
If you can’t go in fastboot mode, use Oneplus MSM tool. See there and there.

Thank you for the time and effort for this thread as I just came from a Sony XZ1 as I was a bit confused by the different posting on how to do what...

Thank you for taking the time to do this. I am now subscribed

Very nice. Subscribed. Thank you.

I've been trying to do this for the past 8 hours.
Here's what I do, please tell me where am I going wrong
- msm 9.13
- update to 9.17
- local upgrade to 10.3.1
- boot system to enable oem unlock, usb debug
- boot to fb, unlock bootloader
- boot system
- boot fb, boot twrp
- flash twrp, both slots
- reboot twrp
here I get different results:
- try to install magisk, all internal storage encrypted. sideload, but still no cigar. try to install on both slots by rebooting twrp to a and b and sideloading magisk, still no cigar
OR
- flash magisk, boot system, no magisk
OR
System boots, we have root, we have everything, but file manager shows emptyness. Can't modify any files on internal storage. Via phone and via PC.
Now tell me what am I doing wrong, please

I think you should format data after unlock. I think it's kinda safety feature if some1 try to get into your storage by unlock bootloader. But wait by some1 to confirm

As far as the change log, that could be a challenge. I have never been able to find the full change log for the international version. The T-Mobile Version is here: https://www.t-mobile.com/support/devices/android/oneplus-6t/software-updates-oneplus-6t. Because this is something we can direct link to, I dont think it should be included in full text here on XDA. I think a link the in first or second post under "useful info" would be sufficient.
As far as the international version goes, I know every verison number by heart.. worst case scenario, I could just google each OTA version and grab the change log from the from the first Android news site that pops up. Unless someone else knows of where one might be at? We could also start at version 10.0.0 because I feel anything older than that is irrelevant.

For changelogs it could be done eventually by grabbing them on the net. There is clearly something between Oneplus and changelogs....
I'm ask for an extra reserved post to have more space and avoid too long posts.

Awesome. I've been running a converted TMobile phone and can't wait b for them to related A10 so I can have android pay back without root

[ROM][OFFICIAL][enchilada][11.0]crDroid Android[v7.30]

NOTICE: crDroid 7.x (Android 11) is now in maintenance-only release mode, and will probably be End-Of-Life'd soon.
I'll be merging monthly Android Security Bulletins from upstream as they're available, and pushing releases, but they're blind builds at this point and I don't have time to troubleshoot them any longer.
Please consider updating to crDroid 9.x (Android 13):

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 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 (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.
- Tap "Advanced", then tap "Enter fastboot" (the already-selected first option).
- 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/enchilada/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 OP6, 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, 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 canary (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:
- 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.

Looking forward on this one, thank you for the effort!

Hopefully android auto and face unlock are working. Thanks in advance.

After running the Rom for 5 days now I can confirm that it's very stable and has tons of customization. Unfortunately though android auto is not working. face unlocking, camera, etc works fine. Would appreciate it if you could fix the android auto issue in the future build.

Anyone else having issues with GPay? I'm using Magisk, hidden, and GPay still won't work.

Is it possible to update crDroid from 6.13 to 7.2 without data formatting (keeping application and data)?

Hey, I have the twrp-3.3.1-18-enchilada-Q-mauronofrio TWRP installed on my Oneplus 6, do I still need to upgrade it to the one which you are recommending? I'd rather go with the one that I currently have and not go through the hassle of updating the recovery. That being said, obviously you would know much better.
Please guide
TIA

Twrp 3.3 should work fine with the rom. You can keep using it if you want to. However, there is no extra step to use 3.5 vs 3.3. You have to flash twrp after flashing the rom so you can upgrade to 3.5 by just flashing it instead of 3.3.

Quick questions, this rom have smart charging feature?

Firstly, I just want to say this is the most awesome ROM I've tried and i've sat here for a week trying every rom I could get find on the net. It's almost flawless... except for a few hugely killer problems that will sadly make this ROM unusable for me... even though I love it soooo much and if only these things worked... this would be the most amazing ROM ever.
1. After installing GPS doesn't work.
2. When I get a phonecall... I hear the ring... but nothing happens on the screen... so I can't pickup the call. I see after i got a missed call... but i can't answer calls when they're calling... even if I go to the homescreen from whatever app i was using when i got the call... click on the phone icon.... still nothing. Can't answer the call.
3. Text messages simply don't arrive. If I flash the rom back to stock Oxygen OS ... then the text message comes through. But it's a bit late when you're trying to get a verifiaction SMS sent to you to open an messanging app. Can't use the app because i can't get the verification SMS.
If these three things get fixed... omg this will literally be the best ROM ever.
There is a 4th issue... and for me it's important... but it's probably not any fault really of crDroid ROM to be fair...
Very surprisingly... and I just wanted to see if it would work.... kali nethunter for Oxygen OS which is for droid 10 installs over the top of this rom which is droid 11... to much surprise! ...and almost flawlessly... only issue is it doesn't recognise HID interface.
Man... with these 4 things working... this ROM together with nethunter would make for the most badass hacker pentester phone on the planet... save only for the exact same thing on a oneplus 7 or 8 pro.
Many thanks to the devs of this awesome ROM... who hopefully can get 1, 2, and 3 working in the not too distant future... pretty please?
4 is more of a hope and a prayer... but it would be soooo freaking awesome.

You have been positing this in more than one thread. This has nothing to do with any rom, and is related to what you are doing with your phone or the phone itself. Telephony is flowless on every Android 11 custom rom for Oneplus 6. And so is GPS, which literally connects in seconds.
First thing you should do is: disable wifi calling, because if your provider doesn't have the feature (or you are not provisioned for it), that could cause your problems. Next, uninstall any mode you might have. Try calling without Gapps.
Also, if you ever used Syberia Rom, you got custom /vendor, which would not work with other custom roms that use stock /vendor. So, you need to re-flash full stock rom onto both slots, which is a pre-requisite for flashing most custom roms. Then follow directions for installing a custom rom.
