going to back to custom ROMS - OnePlus 3T Questions & Answers

hello, I used to be a custom ROM junkie in the past but after some time i got bored and never did it again.
now looking at my current device which i never installed a customer ROM before its quite old as its running Android 8 and i would like to jump to 10 or 11.
I am confident i understand the process but its been a few years and i have some questions:
-for example this is the 1st device i encrypt so i am not sure if this affects.
-the device has no custom recovery so i have to start there but not sure if i have to remove encryption or if its ok.
-Also i would like to see if you have any advice for me or somehting i should pay attention beside install TWRP, format all but storage and install zip file for custom ROM
Thanks

You've missed all the fun with the upgrade to OOS 9.
So, you'll need to upgrade your firmware to 9.0.6 because all the latest ROMs require it. Take your time and carefully read https://forum.xda-developers.com/on...5-0-8-firmware-barrier-t3941164/post79758055.
You do not need to remove encryption (depending on how you upgrade your firmware).
If you've got a locked bootloader (which I'm expecting you do), them you need to unlock it so that you can flash TWRP. And unlocking will wipe all data from your phone. So backup everything you want to keep to your PC.
If you don't boot into recovery after flashing TWRP and install a patched boot image (see https://forum.xda-developers.com/on...ty-disable-oxygen-os-t3922324/post79357241)or flash Magisk, and reboot your phone, you'll lose TWRP because OOS automatically restores the stock recovery.
So the order is:
1. Backup
2. Unlock bootloader
3. Flash TWRP
3. In TWRP flash patched boot image (remember you're still on OOS 5.x so use the right one!) or Magisk.
4. Have fun moving to a custom rom.

[Solved] Official Oxygen OS 5.0 boot loop problem for rooted users

Update: A working solution is listed below for reference.
A detailed tutorial for encrypted and rooted Nougat OOS users on how to flash Oreo OxygenOS without running into the infamous boot loop issue.
Step 1: Remove all fingerprint & pin from the device
Step 2: Backup everything on your PC/Laptop
Step 3: Reboot the device to TWRP bootloader
Step 4: Using a PC/Laptop, flash Blu_Spark TWRP via ADB command
Step 5: Reboot device to TWRP
Step 6: Wipe dalvik, cache, system & internal partition
Step 7: Format device
Step 8: Copy Oreo Rom & no_verity_mod file onto your device
Step 9: Flash Oreo under TWRP
Step 10: Flash TWRP again
Step 11: Reboot to recovery again
Step 12: Flash Magisk Beta for root (I used Magisk beta 14.5)
Step 13: Flash no_verity_mod file
Step 14: Reboot into Oreo Oxygen OS
Your device is now decrypted, rooted and running the latest stable Oreo OxygenOS build.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Seeing as a couple of forum members have messaged me regarding the official update of Android Oreo, I would like to make a proper discussion thread for it.
I just want to make it clear that HatRiGt has made an outstanding effort by making a tutorial thread. -> ([OFFICIAL] [Stable Oreo 8 ] Oxygen OS 5.0 Update [Tutorial-Root] [Mirror] by HatRiGt)
With that said, I believe the title is somewhat misleading. Since a lot of members are under the impression that this Oreo update will be a simple and straightforward process like all previous Nougat updates, except for it's not.
Stock OxygenOS
Rooted with Magisk v14
TWRP Recovery
Device already encrypted
Almost everyone with the device configuration listed above has run into some sort of serious issues, such as boot loop, file system decrypted/corrupted, or a complete data loss.
So far, it seems like the few groups of members that have managed to update their device without any data loss are either users that have flashed the Oreo Beta rom, or users with a non-rooted & stock recovery device. Almost everyone else is facing some form of issues.
I understand that some people have suggested that rooted users should first format the internal storage, before proceeding with the Oreo update. I personally feel that it is an inconvenient method of OS update, since many of us have a huge collection of photos, media files and app settings etc... to worry about.
The purpose of this thread is to address the aforementioned problem for rooted OOS users and to come up with a solution, so that everyone can enjoy this latest stable release of Android Oreo.
Any comments or thoughts are welcomed.
Maybe a stupid idea, but I am a bit noobish in this. Running stock 4.5.15, rooted, K2 TWRP and Magisk.
Is it not an option to just flash stock recovery (via ADB or Root Toolcase), then remove/deinstall Magisk and use the OTA update? After that flash Blue Spark via ADB, reflash Magisk and be good to go?
Unfortunately this is my daily driver company phone so I haven't the time to experiment with it at the moment.
I had some issues trying to dirty flash mine. Didn't know about others' troubles until after the fact.
I ended up with the black screen and blue notification LED. Everything encrypted and unable to go anywhere in recovery mode. Had to do a full wipe and image load; I also am not sure if I had been running my backups for a while, so this could be a lesson learned.

Still experiencing the exact same problem.
The problem is, I can't transfer the zip to my phone to flash.
Under TWRP, any computer recognizes it as a mass storage, but even with adb push/sideload it doesn't work.
Does a full wipe help with that problem?

I saw the same thing. Unable to copy the zip file until I did the full wipe, which means no chance of recovering what was on it, but I'm cutting my losses.
I'm now stuck on the configuration stage, it's just sitting on "Just a sec..." for forever it would seem. Trying to update on Christmas day was a bad decision.
Root *shouldn't* cause issues. But that really depends on what has been changed by root
Twrp will though.
Flashing stock recovery should allow the ota to work without issues.
Having said that it's a major update so factory reset isn't a bad idea anyway.

I had the same idea, encrypted, rooted (no system modifications) and running twrp, I flashed stock OP5 recovery, and updated through the ota and ended up in a bootloop.
I did a nandroid to a usb before updating, but I still lost all internal storage files
so...the no verity is only for decrypted users right?

I appreciated the suggestion, but there are a lot of users with loads of files stored on the device, along with various other app settings, having to wipe the storage or perform a factory reset can be really troublesome. I believe that OnePlus pushed through this stable OTA update with the intention of a seamless update. Endless boot loops and data loss wouldn't be an ideal method of an OS update.
The way I installed the beta 2, was removing the pin and fingerprint before installing magisk through Twrp, at first I got stuck with bootloop, but made it come back to life after installing the ota through Twrp and booting back, removing my pin and then installing magisk.

Okay, so I've been thinking that maybe it's possible for us rooted Nougat OOS users to update to Oreo stable release without any form of data loss.
I've listed the steps to avoid any potential confusions.
You start with stock Nougat OxygenOS (Encrypted) with Magisk v14 (root) and non-Oreo compatible TWRP (e.g TWRP 3.1.1.1)
Flash an Oreo compatible TWRP (e.g Blu_Spark TWRP)
Boot up the new Oreo compatible TWRP
Flash OreoBeta 2
The phone should boot up OreoBeta 2 without any data loss
Dirty flash the official Oreo stable release via the new Oreo compatible TWRP
Flash Oreo compatible TWRP again
Flash Magisk beta for root access
Flash No-verity file
So the basic order of flashing should be Nougat OOS -> OreoBeta -> Oreo Stable
Any thoughts on this?
Are you sure flashing Open beta2 won't compromise the internal storage? I bet no one affords to loose previous photos, apps, settings, etc without full backup.
I've triyed this. All good till i flash 5.0 & Magisk & no verity....
Hello there and Merry Christmas.
I faced to this issue too, fortunately before to update to Oreo. I made a full backup of my data.
My OP5 was running under Oxygen OS 4.5.15 Nougat 7.1.1
Rooted with Magisk V14.5
TWRP Blue_Spark 3.1.1
First I have updated my TWRP to Blue_Spark 3.2
And then I've installed Oreo Oxygen OS 5.0 from TWRP with the full zip.
After the update, my op5 has been bricked and locked on blank black screen with a blue led.
To unbrick my phone I used a tiers softwate to install Hydrogen OS first.
After that I could installed TWRP Blue_Spark 3.2 and then flash to the full zip Oreo Oxygen OS 5.0
My OP5 works as well but...
Right now I'm blocked, Google who usually sends an SMS, does not offer me. Only the authentificatorator or the security code. : /
Be careful, print a Google code to access your account when you go to install Oreo.
I'm waiting for Google to do the right thing.
Hi,
I have a boot loop on my OP5.
I ddirty flashed Oreo and had twrp/magisk.
Any ideas to recover my data partition ? (I had fingerprint/pin)
Best regards,
1) What is that "no-verity" file?
2) Isn't the regular TWRP 3.2.0 good with Oreo?

Isn't a full wipe required even for Oreo Beta builds? Also thanks for starting this thread I'm really eager to jump into Oreo but would love it if no wipe happened.

I think it's possible to flash the Oreo Beta without a full wipe. And yeah, I've got way too much stuff on my device, so I can't afford to wipe my storage.

I never suggested either.
Oneplus don't test using twrp or using root.
Their prescribed ota route, as pretty much every other OEM, is unmodified system partition using stock bootloader.
Twrp or root will affect those and can cause bootloops.
Obviously there's a chance with so much diversity in installs that there can be an issue arises.

Read it all.
I have a Encrypted phone and I was able to recover all.
Actually I was able to restore my Nandroid backup.

Complete setup of Lineage OS

Since in my last post I made a complete mess out of my first time trying to root my K20 and install lineage I wanted to my make a separate post so that I can list all the steps I need to take to correctly setup my phone how I want it.
What I actually want
A rooted device
Lineage OS
Minimal excess files (A clean Install)
Current Steps
Unlock and flash recovery
Backup
Format Data! (It's important if you come from Miui)
Install Q Firmware + vendor
Install LineageOS followed by gapps
Reboot into system and setup device.
Reboot into recovery and flash magisk
Profit???
Feel free to tell me how stupid I am and what I need to add to the list or steps I should take to make this process better.
I also dont know if its possible to get recovery and rom on android 10 versions.
Thanks
Did these steps not work?

They may work as it but I was just wondering if anyone could go into more detail or if there was a better approach and from what Kollachi said there clearly is a better way that what I said.
Since I'm in stock ROM and haven't ever flashed AOSP ROM in this phone I'll just back off lol

I like the details steps but I have a few questions.
(Unlock and flash recovery) From what I can tell there are two recovery's Orange fox and TWRP
(Format data) Just format data or are there other sections I should format/wipe
(Install Q Firmware + Vendor) I have no idea what Q firmware is or what vendor you are referring to
(Install Lineage + gapps) Is there a specific version from the Mi 9T pro since the official site doesn't list it
Any of the two recoveries will work. Q firmware means Android Q. Wile data/cache dalvik that's it. Regarding firmware, there's a clear topic of Lineage OS in K20 Pro forum which is still in unofficially state

1. You can take what you want. Orangefox is based on TWRP.
2. Format data is needed if you come from miui. If you did it you are good to go. But it wouldn't be false to wipe system, dalvic, cache
3.https://downloads.akhilnarang.me/MIUI/raphael/ --> Take 10.4.6.0 or 10.4.8.0 (Android 10 = Q)
4. No there is no specific version.

I would recommend the latest TWRP from here
https://forum.xda-developers.com/k2...icial-twrp-xiaomi-redmi-t3944363/post79823568
The dev is an official TWRP dev, so this version, or something very close to this, is likely to become official in the future.
OrangeFox is a heavily modified TWRP and has a lot of added functionality specific to MIUI. If you wanted to stay on stock MIUI, but debloat and have root, etc. then OF would be the better choice, as it has functionality that lets it play nicely with MIUI (it can remain installed when OTA updates are installed)
As someone new to flashing on Android, I would suggest downloading a 10.4.x fastboot ROM from the site I pointed to in your other post, then follow the same procedure to flash the ROM.
Make your choice based on Kollachi's info and what's important to you (HD Netflix - choose Indian, or a working NFC - choose Chinese)
However you MUST change the flash option to 'clean all'.
At this point you've got a nice squeaky clean starting point.
Boot into the ROM at least once, though it's not necessary to go through all the setup.
After that follow Kollachi's steps but you can now ignore the step to flash vendor and firmware as it's all part of the fastboot ROM already flashed.
Wipe cache and dalvik, format data.
There is no official LOS for this phone yet. Hopefully it will go official in the future.
For now just get the current Android 10 based LOS from here.

When ever I think I have the process memories and I follow the steps on my screen I still somehow **** this up and I cant understand how.
My current steps include
Flash the fastboot with the ROM that you linked me in my first post
Flash the recovery with TWRP (Every time I have then tried going back into TWRP is failed to work and prompted the original MIUI recovery)
Install the TWRP zip from custom recovery to try and fix the issue above (Only had this work once on orangefox and then never had success again)
So now I try to just flash the recovery and boot to it using CMD and it works fine
Move the lineageOS files from my PC to the phone SDCard
If I wipe data and the caches as suggested then the lineageOS zip is now go and I am back to flashing the fastboot ROM to restart the process
I know this might seem like im either stupid or just not getting it but could you or anyone else please make a bullet pointed list with links to what I have to download in order to actually achieve this since I cant do anything correctly even when trying to follow the steps.
(Im going to sleep since I have been trying to do this for hours now and I will check reply's in the morning.
Thanks for the help so far EVERYONE

I just told you what I have done and I'm running it so far without issues.
Robbo just said you should flash the whole Chinese or indian rom but I don't like his steps because:
1. File is much bigger
2. MiFlash is just meh
3. If you forgot to change the flash process you are bricked if you don't take the correct firmware for your phone.
Default option in Miflash is set to "Clean all and lock". Every time you use it, you will need to change it into "clean all" or something other.

Yes flashing the whole fastboot ROM does add the risk, if you forget to change the flash option, but you are guaranteed a clean slate and so less likely to have any niggling issues that nobody else has. I would bet large sums of money that many of the issues you see on here, where only one person has some problem and everyone else is fine, would be solved by fastboot flashing MIUI before installing the ROM of choice.
If you know what you're doing and know when you'll be OK with what you've got and know when it's best to start clean, then going with the vendor and firmware is easier.
But if your unsure and new to flashing on Android phones, I will always suggest go with the overkill and know you've got the clean slate to start with.

It's sounds like the main issue is stock recovery is being restored. This is something that MIUI will do when it boots up.
When you first install TWRP you cannot boot into MIUI before booting to TWRP as you instantly lose TWRP. So you need to boot into TWRP first in order to do something to prevent it being overwritten.
Options are
1
Code:
fastboot boot TWRP.img
2 Use the button combo whilst still in fastboot - power and vol+, hold both until the phone vibrates and the initial logo appears.
Now to keep TWRP you need to either flash a custom ROM, flash Magisk or flash the dm-verity script.
In your case you want to flash LOS, so now you've booted into TWRP go ahead and continue with the steps given.
Also, wait until after you've formatted data before copying everything over. You can access the phone as an MTP device when in TWRP, so you'll be able to connect it to a PC and drag everything across, or you can stick everything on a USB OTG pen, if you have one, TWRP can read data from them too.

The exact problem I have is that I cant transfer any files to the device after formatting the data. I follow the steps correctly and I get into TWRP successfully and then everyone has told me to format the data then install lineage but I cant install the OS if formatting the data removes it.
Get device into fastboot
Flash revocery with TWRP
power the device off
hold volume up and power
boot into custom recovery
format data
move lineageOS onto my device
install lineageOS
reboot
done.
This is the list of exact actions I am doing with no results is there something I am missing or something that is in the wrong order.

The exact problem I have is that I cant transfer any files to the device after formatting the data. I follow the steps correctly and I get into TWRP successfully and then everyone has told me to format the data then install lineage but I cant install the OS if formatting the data removes it.
Get device into fastboot
Flash revocery with TWRP
power the device off
hold volume up and power
boot into custom recovery
format data
move lineageOS onto my device
install lineageOS
reboot
done.
This is the list of exact actions I am doing with no results is there something I am missing or something that is in the wrong order.

After format data, reboot your device into recovery again and transfer LOS, gapps and all files you need.
Format data kills the storage.
I always used to reboot from TWRP back in to TWRP after formatting data, but I've recently seen someone saying that they just unmount data then remount it again. I haven't tried it myself but it certainly makes sense and would be quicker too.

Yes I did that and it worked, unmounting and remounting helps detect the storage in PC

Few questions regarding rooting and flashing.

Hello XDA fam, I just picked up a 3T and unlocked the bootloader.
I was just wondering what the general flashing process was for this
device (A3000). Also a tad confused about this dm-verity ...
disabler zip, is this and format data required every time you flash a
new ROM?

Dm-verity warnings are similar to the unlocked bootloader screen you get, but are red. You get them if you are running stock OOS and modify the system partition.
You don't need the dm-verity disabler unless you've got a dm-verity warnings screen.
Note that you cannot disable the unlocked bootloader warning you get every time the phone boots except by re-locking the phone.
Another thing to note: if you are running stock OOS and flash TWRP, then TWRP will be replaced by the stock recovery when your reboot the phone unless you:
- use a patched boot image like the one from @Xennet's thread https://forum.xda-developers.com/oneplus-3t/how-to/dm-verity-disable-oxygen-os-t3922324/post79357241
- use a custom kernel, or
- use Magisk.
Flashing using TWRP is just like any other phone. If you're changing ROMs then you need to do a clean install (wipe /data and/system).
Some ROMs don't handle an encrypted phone (most Android 10 ones except for Los and PE), so you you have to remove the encryption before using those ROMs (TWRP>wipe>format data).
Finally if your phone is unlocked and running OOS 5.x or lower, and you want to upgrade to OOS 9.x then you'll either have to:
- remove the encryption (but can re-encrypt after installing 9.x) or
- use the modded firmware (that keeps the 5.x bootloader and keys) so that you don't have to remove the encryption. See https://forum.xda-developers.com/on...-5-0-8-firmware-barrier-t3941164/post79758055

Wow thank you for the detailed info, I really appreciate the insight.
I am currently running the latest OOS update 9.0.6 I believe.
Once I have TWRP installed do I swipe and enable modifications?
Flashing Magisk afterwards avoids the bootloop and allows me to
keep TWRP in place of the stock recovery as you said, correct?
So installing most ROMs seems fairly straightforward, following
the flashing instructions. However if I were to install an Android
10 ROM wouldn't formatting data remove all zips and everything
from the internal storage? So at that point I'd have to copy back
all my ROMs and zips back to the phone in TWRP and flash from
this point correct?
Sorry for the loads of questions, my most recent device was a
Note 9, which has a locked bootloader, so it has been a while since
I have flashed anything or used TWRP.

You don't need you enable modifications of the system partition. Any zip you flash will make the system writable if required.
So, just flash Magisk.

Correct. So it's best to take a backup of your current system and backing up everything on internal storage (/sdcard) to an external drive or PC.
The fastest way to take the backup is to use ADB.
Code:
adb pull /sdcard

You'll find that nearly all the rom, kernel, and recovery development threads are under the OnePlus 3 forum in https://forum.xda-developers.com/oneplus-3/oneplus-3--3t-cross-device-development as they are unified: good to flash on both the 3 and 3T.

Updating a rooted Redmi 8 with custom recovery

Hey guys I was wondering something I haven't installed the latest update yet and my phone is rooted and has TWRP on it soo not sure if i can just update with all that or like i should restore the phone to its original state then update
Last version of TWRP I tried (3.4.0-0) did not work properly with Android 10, don't know about the new 3.4.0-1 because I switched to OrangeFox which can decrypt Android 10 without issues.
As for the update process, you need to get the Recovery ROM update package, you can download it from the official xiaomi site, put it, Magisk and your kernel if you use a custom one either on the phone's internal storage or even better your SD card and flash from recovery in this order:
1. ROM
2. Kernel
3. Magisk
4. Wipe Dalvik\cache
5. Reboot to system
I did it exactly like this a few times now, granted it was with xiaomi.eu instead of stock but the process should be the same.
This should just update the phone without wiping anything and with maintaining root, just make sure to do it from a recovery that can decrypt the phone.

Well I have a few questions
By recovery ROM you mean from here https://c.mi.com//miuidownload/detail?device=1900376 the full ROM? like I just flash the ROM file using TWRP well OrangeFox version right and it will keep all my apps and data
Yes, you flash the rom from mi.com.
Don't "just" flash it or you'll loose root and OrangeFox, flash in this order:
1. ROM
2. Kernel
3. OrangeFox (I added this step because you are on official MIUI and the update will replace your custom recovery unless you re-flash it after the rom.)
4. Magisk
5. Wipe Dalvik\cache
6. Reboot to system
Before flashing make sure you are flashing the right rom for your variant and region.
Other than that, you should be good, I updated like this three times and had no data loss.

Question Downgrading from stock A12 to Xiaomi EU A11

I'm planning to go from stock 13.0.2 A12 to Xiaomi EU 13.0.10 A11. Based on what I read, this is what I have to do:
- Unlock bootloader (which will factory reset the phone).
- Start fastboot mode.
- Connect to PC.
- Download the ROM (Recovery for RN11, since it's downgrade I'll have to factory reset but it'll already be done during bootloader unlock)
- Run first_time_installation.bat (or something like that).
Are these steps correct? This will be the first time I flash a ROM and I really don't want to mess it up. Thanks in advance!
The first step is correct, you must unlock the booloader. However, you can't install Xiaomi.eu ROM on fastboot mode, that's only for stock ROMs. If you try to do that using a custom ROM, it could brick your phone. For Xiaomi.eu (or any other custom ROM) you need to install first a custom recovery like TWRP: first downlaod the custom recovery file, then copy it into the storage and then install it. You can do the last 2 things with CMD commands . Then copy the custom ROM file like any other file into the phone's storage, restart the phone on recovery mode and install the ROM from the TWRP interface. I did it like a month ago, I don't remember all the details though. Just look for a tutorial, it's not that hard.
Good luck.

Haha thanks for your reply! This came a bit late, it has been exactly a month since I flashed but I hope this could help someone else. Spes/spesn is listed as recovery on the list but the Android 11 versions only come in Fastboot. When I unlocked bootloader, I had already prepared Pixel Experience and Xiaomi.eu ROM. PE's recovery gave me bootloop so I used the next thing available and flashed Xiaomi.eu .bat file.
I was a bit worried when it was stuck on the same screen for 15 minutes but then it loaded with no problem. Not really sure if I did the right thing or I was just lucky
Indonesia global rom work call recording mi dialer and step counter intalled in eea and no problem
