Backup your stock recovery per this post. If you are too lazy, I can upload my backup from .104 build (C432) to Mega.
Download twrp_bkl_0.7.img from this post and place it in same directory with your ADB.
After successful backup as precaution disable any locks like pattern/PIN/password/fingerprint, reboot to bootloader (fastboot):
Code:
adb reboot bootloader
Then flash new TWRP recovery:
Code:
fastboot flash recovery_ramdisk twrp_bkl_0.7.img
After successful flash reboot device and immediately after confirming command below unplug USB cable and HOLD and keep holding VOLUME UP button, if you won't the new recovery will be overwritten by stock and you can try again.
Code:
fastboot reboot
Tested by myself on Honor 10 8.1.0.104 (C432) with unlocked bootloader and installed already Magisk 16.4 with Magisk manager 5.7.0, Magisk ramdisk persisted after installing TWRP recovery, system boots normal.
Next step after unlocking BL, installing Magisk, installing TWRP recovery -> flashing GSI AOSP, LOS or RR. Only reason I bothered with installing TWRP was that GSI image of LOS and RR don't include opengapps, only AOSP does, so without TWRP you can't have opengapps with these two GSI ROMS.

Nice work. ?
tried to install GSI RR OS, but ending in bootloop, also even after resizing system partition to maximum (TWRP / wipe / resize) opengapps still showing error 70 about insufficient space (which makes no sense, so they really seem to have wrong detection of A/B instead of A for Huawei/Honor devices), though these gzr gapps seem to install successfuly, now if I could figure out the damn bootloop
potential reasons for bootloop - previously installed magisk, wiped also system not only data/cache, installed through fastboot while TWRP there and not only stock recovery, ???
edit: i guess will try flash GSI through TWRP again, quite a waste time to wait each time like 9-10 minutes to find out it can't boot
edit 2: so even flashing through TWRP doesn't help, just stuck on android animation for 10 minutes and then it restarts (and even if you do fatory reset through huawei erecovery it doesnt change anything). maybe can try to restore everything and not wipe system before installing, just factory reset through TWRP (though I remember I read somewhere it's not reliable and it is better to do it through system, but I think that one wipe also internal storage which I wanna avoid)? back to rooted EMUI with TWRP for now, don't have time to try various combinations
edit 3: flashing over TWRP backup without wiping system doesn't help, so it seem it's gonna be magisk or replaced stock recovery i guess, otherwise no idea
BTW the lack of feedback here and trying from other users it's very depressing. they boasted million phone sales and i am the only one in the whole world trying to install TWRP and GSI ROM on this phone?

Don't be disappointed the lack of feedback from users is not many power users have got their hands on this model.
And also we are having different builds.
From the day one I am trying to rebrand my device but no success .
Once I have rebranded to EU I will try and let you know.
Did you flash open gapps nano package through twrp in gsi image?
Did it give you the same error?
tried just pico opengapps as on all phones i flash, that's the smallest, but always end up with error 70 not enough space despite resized system partition in TWRP and many GB available, the other unofficial GZR zero gapps build i mentioned seem to be flashed successful in TWRP, but in any case no luck with booting

Did you format your phone before trying GSI ?
Try formatting phone and remove some system apps and then flash gapps it will mostly solve the problem.

Don't be upset – e.g. I didn't receive my Honor 10 yet. You won't be the only one for sure, you're just the first one to do it, which is super nice for others because it motivates them to do so as well!
Just wondering: does it make a difference for TWRP wether I own the 6gb or 4gb version?

I did factory reset (data, both cache) and also wiped system partition, gapps would be the least issue, as I said that GZR should work, but my system doesn't boot, no matter how times I wipe everything through TWRP or stock recovery after flashing system.img, since they say it's normal to hang at first boot and then wipe and then it should boot, but it doesn't work for me. also of course tried to power off phone since some people said it helps to do it after flashing. what I haven't done it's fastboot -w which should be some better wipe. some people say also you should remove magisk ramdisk, though I forgot to back up original, backed up just stock recovery. and also I haven't tried to flash everything with stock recovery, though first flash I did was through fastboot anyway and not through TWRP and it didn't make difference
so last few things left to try:
- fastboot -w for total wipe of data (better than TWRP? though it should be same as Format data in TWRP which wipe everything including internal storage which I wanna avoid since backing up 15GB TWRP backup file it's kinda annoying and my system has problem to do it)
- flash with stock recovery (I have backup, no big deal)
- remove magisk ramdisk and flash with stock ramdisk (forgot to make backup, can't replace)
though I am tired of it for now, spend last night like 4 hours dealing with it until 2AM and I also need to take care of children

I don't think RAM has something to do with anything, but that sounds like Chinese version since EU has always 4GB and only difference is storage, so you will have different ROM

So I just read more about the GSI/Treble stuff and it said somewhere that modifications like Magisk probably lead to problems with the GSI flash.
Which is why I would try to get rid of the magisk ramdisk first.
I'm not an expert in this at all but maybe this helps.

yeah, now if someone could extract for me from 0.104 firmware for C432 that stock ramdisk, because I have some problems with mega to download it and I just need the stock ramdisk, nothing else, I have stock recovery backup but forgot to make ramdisk backup

edit 2: tried to replace magisk ramdisk with ramdisk from Honor View 10 BKL09 (same as our working TWRP) but it seem I end up after flashing it, wiping and flashing system.img in TWRP/erecovery bootloop, it's not showing android booting logo like before (but hey at least no need to wait 10 minutes to find it's fail) and either go to huawei ercovery, if I perform factory reset there then it boots to TWRP, but can't boot anywhere else besides these two

I requested this image. Recovery has been established. When I enter the recovery, it requires a password to decrypt the system partition, I enter it (the same after switching on the phone), but a message is displayed that the password is incorrect. help me please.

The problem is currently we don't have full
ROM to revert to stock and if we brick our device there is no proper way to revert to stock.
Our model even doesn't have SD card support.
Just wait for some time for someone to provide proper way.
When i flash a treble rom, I have a bootloop. I returned back with eRecovery directly on the phone.

We do have a way to download full ROM.
http://pro-teammt.ru/firmware-database/?firmware_model=COL-L29C432
1. Search here for your exact model (change numbers after C432 to find ROM for your phone) and search for your rom version (B104 or B120)
2. Double click on "filelist" on the same row as FullOTA-MF
3. From filelist link menu download update.zip file (it should be really big, like 2+GB)
3. Extract UPDATE.APP file somewhere (eg. Desktop)
4. In settings of HuaweiUpdateExtractor (link: https://forum.xda-developers.com/showthread.php?t=2433454) uncheck "verify header checksum" and open UPDATE.APP
5. Extract any img (Be it ramdisk.img, ramdisk_recovery.img or system.img) file that you need from UPDATE.APP via HuaweiUpdateExtractor
You just got whoole stock rom and img files that you can flash. Tested by myself with flashing back original ramdisk, ramdisk_recovery and system.img and everything worked well.
This thread is meant to address all the common hurdles that are commonly faced by people who are new to treble devices (chef to be specific) and help them to troubleshoot/avoid some small yet critical steps during flashing new ROMs and working with fastboot and recovery in general. It will be continually updated with new stuff as it goes along.
I will be referring to the Motorola One Power and Moto P30 Note as chef only from now on.
The unlocking guide is available in This XDA Thread!
IMPORTANT:
1. Flashing refers to the process of doing a clean flash, with the inclusion of fastboot -w command
2. Latest ADB and Fastboot drivers are required to be installed, else the installation may halt mid-way.
3. Stock ROM refers to the Android One ROM for the Motorola One Power [XT 1942-2]
IMPORTANT: AS OF RIGHT NOW, PEOPLE WHO HAVE INSTALLED STOCK PIE (EITHER VIA UPDATE OR FIRMWARE) WILL NOT BE ABLE TO USE ANY OTHER ROM OTHER THAN THE STOCK PIE ROM. RADIO INTERFACE LAYER IS BROKEN IN OREO SOURCE BUILT ROMS AND THAT CURRENTLY INCLUDES LINEAGE 16 SO PLEASE WAIT FOR PIE SOURCE CODE FROM MOTOROLA FOR THAT TO BE FIXED.
1. I unlocked my chef . How do I flash TWRP in place of the stock recovery?
Solution:Currently you cannot as there is no recovery partition in the device. You have to manually boot TWRP onto the device using fastboot to use it. Follow as directed:
Boot the device into fastboot mode
Use command fastboot boot <path/to/TWRP.img> to boot TWRP temporarily.
2. I am done with TWRP and I want to flash Lineage OS 16 on my chef. I simply flash the .zip archive right?
Solution:No. Before you flash anything,
Take a backup of atleast your EFS and PERSIST partitions using TWRP and off-load it for safekeeping to restore in future if needed. You can also trigger a full backup if you require.
SUPER IMPORTANT: Flash this .zip file to copy the System A/B partitions. If this step is skipped, you will be responsible to brick your own device. THIS STEP IS ONLY REQUIRED ONCE AND ONLY ONCE IN THE LIFETIME OF YOUR DEVICE! YOU WON'T BE NEEDING THIS THE NEXT TIME YOU FLASH ANY ROM. .
After that, flash your dearest custom ROM and get going.
For Lineage OS 16, follow This XDA Thread.
3. I am done testing LOS 16, I want to flash a GSI. Shall I use a stock Vendor Image for the GSI on my chef?
Solution:No. The stock Vendor image is causing bootloop issue in most GSIs. It is recommended to use Lineage OS Vendor to flash a GSI on chef. So flash LOS and then flash your favourite GSI.
Also, Super Important: for those who haven't used lineage before flahing a GSI, it is required to boot Lineage OS first before flashing a GSI.
4. I am done experimenting, I want to go back to the stock image. How do I proceed?
Solution:Follow this XDA thread for it. And don't install OTA updates directly from the device. It will come in the next step.
5. I want to install OTA updates on the stock ROM. How do I proceed?
Solution:Follow this XDA post for it. The installation process is described here. You have to be clever enough to get the appropriate OTA update.

Anyone have flashed GSI ROM? FOr me after flash GSI HavocOS have bootloop :/
DIdn't flash copy system A/B partitions, stuck on bootloop with custom roms.
Watched some youtube videos and didn't read this post before flashing custom ROM. Flashed Custom ROM without flashing A/B partitions. Now I have a phone stuck on bootloop when done anything in TWRP. or I can use my phone with stock ROM installed by fastboot method.
Installing or restoring anything from TWRP results in boot loop.
Restoring the backup I made before flashing, completes the restoration process normally. But when rebooting to system, TWRP prompts me that no OS is installed. If I reboot anyway, its either stuck on bootloop or reboots to recovery and asks me to try again or factory reset, or boots into bootloader mode.
Installing custom ROM begins with Step 1, takes a bit time and starts step 2 and shows completed. Doesn't echos any comments. But when i reboot, same prompt shows saying no OS installed. Reboot anyway and stuck on bootloop or reboots to recovery and aks me to try again or factory reset, or boots into bootloader mode.
Now I installed stock ROM with fastboot method and phone is boots up into system just fine.
Sometimes TWRP can't mount anything.
So am I stuck with stock rom or is there any solutions?
Also, installing stock ROM with fastboot mode showed this error in between scripts
(bootloader) is-logical:xxx_a: not found
and
(bootloader) is-logical:xxx_b: not found
but is able to use the phone just fine with stock ROM.
After some time I got a second Axon 10 and I spend some time figuring out what was possible with this phone in terms of root, custom ROM etc.
My results are as follows.
What is working:
Android 9 + Magisk and TWRP
Android 9 + TWRP + Custom ROMs (LineageOS 16 and patched GSI)
Android 10 + Magisk and TWRP
Android 10 + Magisk and MicroG flashed via Magisk (= stock ROM without Google Services)
Android 11 + Magisk
What is not working:
Android 11 + Magisk + TWRP (TWRP logo flashes randomly but TWRP does not load).
Android 11 + Magisk + MicroG (the nanolx patching script does not work with Android 11 as of yet)
Encryption in Custom ROMs
Method to flash files via EDL
Unzip / unrar my files into the backup\full folder of the EDL tool and choose restore + full in the tool.
Unlock Bootloader:
Before you try any of the files, you MUST unlock your bootloader!
BACKUP of your data as it will be lost!
Download the EDL tool from this Thread
If your phone is not on android 9, you must go back to Android 9 first. e.g. by using my Android 9 1.9 backup.
After you restored it, restart while holding the volume + key and do a factory reset / format data.
Boot into EDL again and unlock the bootloader.
Now you are on android 9 with unlocked bootloader.
From here you can follow the other guides in the form and install TWRP or lineageos. Or flash one of my files below.
Flashing EDL files:
Unzip / unrar my files into the backup\full folder of the EDL tool and choose restore + full in the tool.
I put all my files into this MEGA account: MEGA
Android 10 version 2.9 Magisk + TWRP
Android 11 version 3.5 stock
Android 11 version 3.5 Magisk
Android 10 version 2.10 stock
Android 10 version 2.10 Magisk (TWRP can be flashed with Magisk)
Install MicroG:
Only works on Android 9 and 10.
Before you install MicroG you must patch the stock ROM to allow for signature spoofing.
The patcher script I used is on https://downloads.nanolx.org/NanoDroid/Stable/ When I write these lines the up-to-date-version is NanoDroid-patcher-23.1.2.20210117.zip
Reboot.
Install MicroG from the Magisk repository.
After a restart there will be error messages that google apps keep crashing. With each warning, disable the apps one by one.
When you reboot again, no errors should appear and MicroG should report that it is fully working.
You can add the Bromite Framework and give F-droid system rights. Both are available from the Magisk repo.
Updates will likely install the Google apps again and uninstall Magisk...
Revive phone:
Not really related, but I bricked my phone several times.
If your phones does not boot anymore or hangs in a bootloop, try accessing the EDL mode.
The easy way:
Boot while holding volume -
The hard way:
Old Volume +, volume - and power until you end up in EDL. The screen will be black, so it helps if you have the Phone connected to Windows and can hear the system sound when the USB sees a connection.
In anyway you can then use the EDL tool to restore / flash an EDL image.
On custom ROM support:
Well there is LineageOS 16 by Unjustified Dev. https://forum.xda-developers.com/t/rom-unofficial-zte-axon-10-pro-9-lineageos-16-0.3992127/ It works well. But has a patch level that is outdated by now.
On top of it you can install the GSI ROMs created by Rafyvitto. The latest one is Resurrection Remix https://forum.xda-developers.com/t/...nofficial-resurrection-remix-q-8-6-7.4172527/
with a security patch level of mid 2021. Which is recent enough to use. The stock roms are not much better.
With both Custom ROMs, encryption is not working which poses a privacy/security risk when your phone is stolen. Do not forget that your phone does not only contain your photos and data but also your passwords to your accounts.
Added Android 10 2.10 files.
Its nice to see anything new for this phone. I wish I can use these roms but I have the American version.
Hi and thanks for your work and your files.
I'm stuck on "Loading the programmer: prog_ufs_firehose_sdm855.elf >>>", if I try to recover your edl files with EDL Tool, v 3.25.
I have to choose option 2: "Restore Full EDL from backup", right?
Is there a way to check if the bootlaoder is really unlocked?
Thanks in advance
OK, I was able to solve the problem with the "programmer" and try the backups. The next step was almost clear. The device is stuck in bootloop. I've already tried all the backups I could find on Mega. After the EDL Tool has done its work and the device has restarted, the mobile phone goes into the boot loop. And now? So the starting position was: Android 9 with an open bootloader. Maybe someone has an idea?
After I couldn't get the device out of the bootloop, I flashed the A2020G_PRO_V1.6_FULL_EDL via MiFlash and then did an OTA update to 1.8.
Then I tried unlocking the bootloader again, which unfortunately didn't work. The flash is carried out without errors, but the device then apparently does not start in the desired Fastboot mode.
Thanks for your guide. However am I missing something with the Android 11+Magisk installation? I restored all the correct files and everything flashed correctly, however upon reboot there is no Magisk installed anywhere. Did a factory reset after the flash and still not there. Tried installing Magisk via his github and tried patching the boot.img again and it says success but after rebooting it says Magisk is not installed.

Maybe you need to switch the slot in TWRP. It sounds as if you install it to the other slot (like A) an then boot B. Or vice versa.
