Huawei P10 VTR-L29 (dual SIM) and Lineage 18.1, 19.1, 20 - Huawei P10 Guides, News, & Discussion

Works!
But you have to solve some basic problems:
Unlock bootloader. Solved here: https://github.com/mashed-potatoes/PotatoNV
You have to patch the recovery_ramdisk original partition. Patch with The Magisk https://github.com/topjohnwu/Magisk
Take the recovery_ramdisk partition from the latest full upgrade file VTR-L29 9.1.0.297(C432E5R1P9), VTR-L29C432B185
Download the lineage .img file https://sourceforge.net/projects/andyyan-gsi/files/. You will need the -arm64_bgN.img.xz version
Reboot the phone to fastboot mode and execute command: fastboot flash system xxxxx-arm64_bgN.img
fastboot reboot
After reboot the phone go to the erecovery (Volume up to 3 secondes) and do wipe data / factory reset
Boot phone in to clean Lineage system and do the first Lineage configuration
Reboot phone to fastboot mode
Flash the Magisk patched recovery_ramdisk partition: fastboot flash recovery_ramdisk magisk_patched_recovery_ramdisk.img
Now you have a full working Huawei P10 with Lineage 18.1, 19.1 or 20.x system, but every time you will have to boot the phone with "Magisk boot cheat" means Volume Up + Power button. When appears the Huawei logo release all buttons. https://topjohnwu.github.io/Magisk/install.html
Not necessary - permanent boot to recovery cheat. When the phone boot and the yellow text on black wallpaper appers, use the first option and go to eRecovery (Volume Up for 3 seconds). In eRecovery select Wipe data / Factory reset, confirm and reboot the phone. The phone will reboot to recovery and will boot in to the Magisk root boot system (the wipe will not be called).
Go back to point 11 state. The RAM card have not to contain a /dload directory!!!!! Power off the phone. Press Volume Up + Volume Down + Power and release all buttons, when Huawei logo appears. Now you will see aclean EMUI screen which will respond - OS Upgrade not successfull. Go to reboot and the permanent Recovery reboot byte will be cleaned.

here's a great alternative for magisk

that's for EMUI "9.0"
works great, i did test some magisk module such as uka tool and it works without any issues.

[How To] Magisk 13.2 on B19

After days of trial and error, I can conclude that B25 has serious issues with Magisk - Magisk Manager will fc on every root permission prompt, the Magisk app is also not usable. I've raised this issue here as it seems it is producing a code 14 error on opening the database. This problem seems to be B25 or Axon exclusive.
Since B25 stripped bootloader and caused the Magisk to crash, I see no reason to use it and to get Safetynet to work, rolling back to B19 is the next best move.
I will describe my process (which involves a wipe) and successfully get Magisk 13.2 to work and Safetynet all passed without extra modules.
1) Download the B19 EDL (B19-NOUGAT_FULL) and have MiFlash ready
https://forum.xda-developers.com/axon-7/development/edl-emergency-dl-mode-twrp-unlock-t3553514
2) Flash B19 EDL by using
Code:
adb reboot edl
3) Boot to stock recovery by pressing Vol Up+Power, choose a wipe/reset
4) Boot to Bootloader, install TWRP
Code:
fastboot flash recovery twrp-3.1.1-0-ailsa_ii.img
5) Boot to TWRP and sideload Magisk 13.2
Code:
adb sideload "magisk v13.2.zip"
6) Boot to system
7) Enable USB Debugging and run
Code:
adb reboot disemmcwp
Magisk should be working and it should pass the SafetyNet check. You now have a clean phone to play with and stay away from B25.

If you're stuck/bricked/bootloop while going back from a Custom ROM to Indian Stock

See guys, we do not have an option to install stock C675 if everything is wiped. ( I mean to say something equivalent to EFS partition where imei resides ). Then what best can be done here is get your device working in Lineage and try some apn creation fixes which I'll post below for Volte. If it works, well and good. If it does not, we need to wait and swap sims till we get the official stock system.img and boot as well as recovery ramdisk out from a dev or Honor's side. They do not have it in their database and so its difficult for them too to install it from scratch as they need every rom partition and in the treble devices, its a different way than samsung's odin or Mi's flashtool.
Now follow the exact steps below which I did and got a working device :
Things to download :
Berkley TWRP Official, Lineage OS - [ 1. system.img from Garbage folder. (Latest) , 2. ROM zip to update the ROM to latest from TWRP later.] , Stock Recovery from XDA, Luk's Gapps.
1. Install Berkley Official TWRP latest one from XDA thread (with NO mod) through fastboot.
2. Always use the button combination (power+vol up) to boot to twrp as soon as it gets flashed and you remove the wire.
3. Once it boots, wipe data, system,cache. After that, go to "Format data" option in TWRP and format it. (Its different than wipe)
4. Restart in TWRP.
5. Go to fastboot mode from TWRP and flash stock recovery through fastboot by using ramdisk command.
6. Flash system.img which you downloaded through fastboot and then as soon as it gets installed, do not boot it and instead go to stock recovery from button combination and click on factory data reset. Once done, let your phone boot.
7. Once you boot, setup your phone and flash TWRP Image through fastboot again. (Do not wipe anything on that.)
8. Once flashed just boot to TWRP and flash Lineage 15.1 "zip" as well as gapps through ADB sideload or USB drive. Do it one by one, first OS zip and then reboot to TWRP and do the same process for Gapps zip. Just make sure, you do not wipe anywhere after step - 4.
9. If you follow the exact process, you get a working ROM.
Credits : I would like to thank Luke for Lineage 15.1 . If we are midway, we have no other option to go back to C675 and this is the only option mentioned above to get a Bug free device other than Volte and camera. For camera, there are stock ones available for Magisk.

[RECOVERY][IME][22.06.2020][OFFICIAL] TWRP 3.4.0-0 for HTC U12+ aka Imagine

Code:
*** Disclaimer ***
All flashing is done at your own risk!
While nothing from this thread should break your device,
don't come back here blaming anyone if it does!
Hello Guys and Girls,
the title is obvious: Here is a twrp build for the HTC U12+. I spent quite a bit of time together with the dear @Captain_Throwback to get everything working.
At this place a huge thanks to @Captain_Throwback for helping me, even though not having the device at his hands!
Instructions:
With A/B devices the command
Code:
fastboot flash recovery recovery.img
is not possible, because these devices generally don´t have a recovery partition any longer. The recovery sits now in the ramdisk of the boot.img.
So how do we get TWRP on it?
The first option is to just boot TWRP temporarily with the command
Code:
fastboot boot twrp.img
. This will just boot up TWRP, not actually flash it onto your device. After rebooting the phone, TWRP will be gone. This is a great option for those, who just like to flash their phone one time, don´t want to modify the boot.img and don´t need a permanently installed TWRP.
The second option is to use the twrp flashable installer zip to install TWRP permanently to your ramdisk from the booted TWRP or magisk manager! Installing from Magisk Manager was made possible by @osm0sis!
So you see there are generally 2 steps needed on A/B devices now.
First booting TWRP. Second flashing the installer zip.
But and now comes HTC into play. When permanently flashing TWRP zip touchscreen gets disabled, because HTC added a nasty little check into the touchscreen driver. If it detects that the phone is in recovery mode it disables the touchscreen.
Luckily we found 2 ways around that!
First way is to have a custom kernel, that has this check patched out!
Second option is to use a zip we provide here, that also patches your kernel, to avoid tripping this check. The downside of flashing this zip is that all commands like
HTML:
adb reboot recovery
, hitting reboot to recovery in magisk manager and finally reboot to recovery in TWRP are not working and only boot to the OS!
How to temporary boot TWRP:
1. You need a working fastboot and adb environment! Your device´s bootloader must be unlocked!
2. Download the twrp.img provided in this thread and copy it to your fastboot folder (pay attention that firmware version matches)
3. Open a command prompt in your fastboot folder!
3.a While your phone is booted to the OS and USB debugging is enabled, type:
Code:
adb reboot bootloader
4. You need to fastboot boot twrp currently
Code:
fastboot boot <filename of the twrp.img>
example:
Code:
fastboot boot twrp-3.2.3-2-ime.img
5. Wait for twrp to be booted
6. You´re now in TWRP
7. Please note that you need to fastboot boot the TWRP every single time you need it. After a reboot it will be gone!
8. Important:
Please note that
Code:
fastboot boot twrp.img
(like done in step 4) will also break OTA functionality. More about this in the FAQ.
How to permanently flash TWRP via the .zip installer
1. Make sure you have a working fastboot and adb environment! Your device´s bootloader must be unlocked!
2. Download the flashable TWRP installer zip provided in this thread!
2a. If you´re on a stock kernel that has no touchscreen fix for recovery included please also download the touchscreen_hexpatcher.zip
3. Flash the TWRP-Installer.Zip from the booted TWRP or Magisk Manager on your phone (hit the + while in modules section)
3a. Important: Directly afterwards flash the magisk zip from TWRP or Magisk Manager
If you don´t flash it you will only be able to reboot to TWRP, regardless of the option you choose
4.Only needed when on stock kernel without touchscreen fix:
also flash the touchscreen_hexpatcher.zip from TWRP or Magisk Manager
Be aware that flashing touchscreen_hexpatcher.zip will make touch work when using stock kernel but render all recovery related commands unusable.
This includes
Code:
adb reboot recovery
, reboot to recovery from magisk manager and reboot to recovery from inside TWRP.
To get into TWRP you first have to reboot to bootloader and from there on to TWRP/Recovery!
5. Reboot
6. Congratulations: you can now reboot into your permanently flashed TWRP
How to permanently flash TWRP via the TWRP.img file inside TWRP
1. Make sure you have a working fastboot and adb environment! Your device´s bootloader must be unlocked!
2. Download the twrp.img file from the offical twrp site
2a. If you´re on a stock kernel that has no touchscreen fix for recovery included please also download the touchscreen_hexpatcher.zip
3. Boot to TWRP. Navigate to Advanced -> Install Recovery Ramdisk -> Choose the twrp.img downloaded earlier. Wait for the flash to be completed successfully and do either 3a or 3b.
3a. If you want to be rooted flash the magisk.zip
3b. If you don´t want to be rooted navigate to Advanced -> Fix Recovery Bootloop to be able to boot into system
4.Only needed when on stock kernel without touchscreen fix:
also flash the touchscreen_hexpatcher.zip from TWRP or Magisk Manager
Be aware that flashing touchscreen_hexpatcher.zip will make touch work when using stock kernel but render all recovery related commands unusable.
This includes

To get into TWRP you first have to reboot to bootloader and from there on to TWRP/Recovery!
5. Reboot
6. Congratulations: you can now reboot into your permanently flashed TWRP
Few tips and tricks:
1. You need to mount ext_sd card before you can access it in the file manager
2. Go to mount and click on mount usb storage to access the ext sdcard when connected via USB
3. Don´t forget you can connect an usb device via usb-otg to backup/flash stuff from/to an usb storage device

Touchscreen hexpatcher | Mirror (AFH) - SEE IMPORTANT NOTES BELOW:
Only needed when on stock kernel without touchscreen fix
Flashing touchscreen_hexpatcher.zip will make touch work when using stock kernel but render all recovery related commands unusable.
This includes "adb reboot recovery", reboot to recovery from Magisk Manager and reboot to recovery from inside TWRP. To get into TWRP you first have to reboot to bootloader and from there on to TWRP/Recovery!
Known Issues:
MTP is disabled in official TWRP. This is currently an issue on several A/B devices. - Enabled since 3.2.3-1
Official TWRP can´t decrypt HTC Firmware on Android Pie!
NOTE: The unofficial TWRP image has MTP enabled for fastboot booting ONLY.
fastboot booting TWRP mounts the system RW and breaks ability to take an OTA.
Please take a look at FAQ, found in the 2nd post here. It contains more information
Bug Reporting:
If you have an issue, the first step is to post a recovery log so we can determine the cause of the issue. This is done in recovery using Advanced -> Copy Log, or adb pull /tmp/recovery.log. Once a log is uploaded we can determine how best to proceed. NOTE: Posts that are reporting bugs or issues without an accompanying recovery log will be ignored! Additionally, providing details about your device setup, including variant, firmware version, and exact steps to reproduce your issue will also be helpful in diagnosing the problem.
We need your help!

Tips on how to build TWRP for the U12+ yourself:
To build TWRP you need to use this branch as your device tree:
https://github.com/freak07/android_device_htc_ime
Additionally you these commits from gerrit to your twrp tree!
https://gerrit.omnirom.org/#/c/android_bootable_recovery/+/31760/
https://gerrit.omnirom.org/#/c/android_bootable_recovery/+/31207/
https://gerrit.omnirom.org/#/c/android_bootable_recovery/+/31021/
Depending on the base you're building for, you may need to comment/uncomment the PLATFORM_SECURITY_PATCH flag for your respective build if you want to fastboot boot the twrp.img. If the patch level of the image doesn't match the patch level of the current system, decryption will not function when fastboot booting the image. If installed via zip, the patch level doesn't matter, as it is automatically updated from system using @topjohnwu & @nkk71's resetprop.

F.A.Q.:
Q: Which TWRP.img to choose for my current Security Patch State
A: For the old base 1.15 use on of the unoffical 1.15 release found in the OP.
TWRP Image 3.2.3-1.img decrypts devices, which run firmware on the 1st June Security patch State.
TWRP Image 3.2.3-2.img decrypts devices, which run firmware on the 1st September Security patch State.
The zip installer (also from the 3.2.3-2 release), however, will work on any patch level, but if you're on stock kernel, you will still need to flash the hex patcher or a custom kernel to have working touch when rebooting into recovery mode.
Q: I´m not able to fastboot boot the recovery, because the command won´t execute properly.
A: Update your adb and fastboot binaries to the latest one found here:
https://www.xda-developers.com/google-releases-separate-adb-and-fastboot-binary-downloads/
Make sure you´re using the original cable.
Make sure you are in bootloader mode.
Try different USB ports on your machine.
On windows make sure you have the latest usb/mtp driver installed properly when the phone is connected in bootloader mode.
Q: I flashed the permanent twrp installer zip and now my touchscreen is not working.
A: This happens when you´re on stock kernel and did not flash the hexpatch-touchscreen zip found in the OP.
Q: I flashed the permanent twrp installer zip and the hexpatch-touchscreen zip found in the OP. Now commands/actions like
Code:
adb reboot recovery
reboot to recovery button in magisk manager
reboot to recovery button in TWRP
are only booting me straight to the OS.
A: As mentioned in the OP flashing the hexpatch-touchscreen zip will break the reboot to recovery command and associated actions.
To get to twrp reboot to bootloader and from there choose reboot to recovery with volume buttons and confirm with the power button.
Q: I flashed the permanent twrp installer zip, booted to the OS and lost root
A: Directly after flashing the twrp installer zip flash the magisk zip to keep root!
Q: I only fastboot booted TWRP but now my OTA functionality is broken.
A: Fastboot booting the twrp image trips a check, this check isn´t able to determine if system has been modified (because it receives no output) and subsequently assumes it has been modified.
this breaks verity on system and probably vendor. Resulting in non existing OTA functionality.
If you are interested in a more detailed explanation please follow this link:
https://github.com/TeamWin/Team-Win-Recovery-Project/issues/1301
to check if system has been modified check the following path:
"/sys/fs/" + Current_File_System + "/" + block + "/lifetime_write_kbytes"
Current_File_System is ext4 on the U12+
block is related to your boot_slot. so check the partition table here:
https://forum.xda-developers.com/u12-plus/how-to/guide-how-to-root-u12-magisk-tips-tricks-t3802583
if you´re on slot A: system_a is sda18
if you´re on slot B: system_b is sda19
Example:
I was on slot B so the file I needed to check was: `/sys/fs/ext4/sda19/lifetime_write_kbytes`
if this file shows 0 system was not modified. Any other value means it was modified and you will not be able to take an OTA!
Same check applied for vendor! you just have to adjust the path.
Slot A vendor: sde19
Slot B vendor: sde40
Example to check if vendor_b has been modified: /sys/fs/ext4/sde40/lifetime_write_kbytes
To restore OTA functionality follow this post:
https://forum.xda-developers.com/showpost.php?p=76606113&postcount=3
or alternatively:
1. after updating your device via RUU or OTA, patch the boot.img with magisk (look at my guide thread)
2. run the following command on either a terminal shell on the phone or via adb shell on your pc(don´t forget to grant su permissions) to obtain an untouched system.img:
dd if=/dev/block/bootdevice/by-name/system$(getprop ro.boot.slot_suffix) of=/sdcard/system.img
3. store this system.img somewhere safe
Additional info:
you can also backup vendor this way!
dd if=/dev/block/bootdevice/by-name/vendor$(getprop ro.boot.slot_suffix) of=/sdcard/vendor.img

Q: Is there a way to restore OTA functionality and keep using TWRP?
A: Yes there is. Please read below! thanks to @osm0sis who came up with the idea!
Temporary Workaround for TWRP mounting /system as RW
the issue linked here: https://github.com/TeamWin/Team-Win-Recovery-Project/issues/1301, which is causing TWRP not being able to mount system as read-only, results in a non pristine system partition after booting TWRP once.
The following file will allow TWRP to mount system as read-only (and therefore keeping OTA functionality)
That means after the following procedure, you can restore an untouched system.img, keep TWRP flashed on your device and simultaneously be able to take OTAs!
Instructions:
1. Download the following file https://www.androidfilehost.com/?fid=1322778262904004337 and extract it! (also as attachement to this post)
2. Copy/Replace the .twrps files to
/persist (make sure to grant the correct permissions afterwards! 0664 | rw-rw-r-- )
/storage/emulated/0/TWRP
with the one you just downloaded
3. When now booting/flashing TWRP system will get mounted as read only.
4. You can now restore a pristine system.img to your device! TWRP shouldn´t mount it as RW now!
5. Check if everything worked by following the guide above (check file lifetime_kbyte_writes for your active system partition)
A huge thanks to @MassStash for testing all this!

noob question: can I format data partition and install magisk without force encryption flag like HTC 10? or is that impossible without decrypt the partition?

I didn’t try it.
If you could try it and report back to confirm that would be great :highfive:
Nice work guys. Thanks @Freak07, @Captain_Throwback and all others who are still with as, as well as those who had to leave to soon - you'll be remembered.

Might be a stupid question but did you try booting in fastboot? AFAIK it only works in fastboot

Yes that too, just hangs at booting... It is the same procedure at the U11. You boot TWRP in Bootloader and flash from Download Mode. Fastboot is the command for both.

Not the person you replied to, but since I have the same problem, I followed the steps in OP, and since it's only 2 steps, I'm sure the other person performed the "adb reboot bootloader" step.
Ah, Ok. Interesting, it worked the first time for me, have you tried redownloading the TWRP img and trying it again? If so, then it may be a problem specific to your device, in which case @Freak07 should be able to help you out better

Ah, yes, I forgot about that lol. I do apologise, I'm quite tired. If it still doesn't work after redownloading then you'll need to wait for @Freak07 to help you out, as I mentioned above. Apologies that I couldn't be of more help and I hope you two manage to get it working

To both of you.
Try both bootloader and download mode for booting. Although only bootloader should work for booting.
Make sure you have the latest fastboot and adb drivers!
Try different usb ports.
What happens if you try to fastboot boot a stock boot.img?
Thanks @Freak07, @Captain_Throwback. TWRP_3.2.2.0_Imagine.img is worked.

Great news! Thanks everyone for your hard efforts! Get my U12 at the end of the month so looking forward to flashing. Hopefully Lee will have a nice ROM for us by then too

Tried all available USB ports, two different cables. Where do I get a stock boot img for US Unlocked? Also while in bootloader, the only command that works is "fastboot reboot bootloader". "Fastboot reboot" and "fastboot reboot download" does nothing.

Could you please post everything from your terminal?
And update the fastboot and adb binaries with the one from the following link for your current OS beforehand
https://www.xda-developers.com/google-releases-separate-adb-and-fastboot-binary-downloads/
No it doesn’t matter I did the same.

You can extract it from the US firmware zip linked in the firmware thread.
Is fastboot devices showing your device?
Did you update your fastboot and adb binaries to the ones found here for your OS?

Low and behold after updating the binaries twice and redownloading TWRP.img for the third time, it finally booted to TWRP. Cancelled decrypt and kept "Read Only". Flashed your Kernel successfully except for preload error due to not mounted. Rebooted and everything seems good, shows Kirisakura_1.0.
Thanks for the help!

Xiaomi Mi 10 5G bricked after reboot (successfully flashed before)

Hi. I just received Mi 10 and tried to flash it with xiaomi.eu rom (native one - Global which doesn't support 2 SIM). It was pretty hard as it often declined to boot to the system. Finally I able to flash it successfully and ROM detects both SIM cards. But another problem appears: randomly after reboot phone lose `system` and `data` partitions and stops booting while nothing was touched.
In TWRP (using Chinese TWRP 3.4.1b-0313 by wzsx150) it shows that `data` partition is empty (what cannot be as it contains a lot of apps data) and unable to mount `system_root`. When I ask to reboot to system is says "No OS installed! Are you sure you wish to reboot" that is also strange - OS definitely as installed. One more time - no operations on system partitions were done before device bricked, it just randomly stops booting. While after last installation I rebooted it about 10 times to ensure it works. And after night - it goes to fastboot screen again. While without reboot it works for a long time (before boot uptime was about 6 days).
Device were unlocked after 7-days timeout successfully.
Actions I am doing to flash device (using Linux):
`fastboot flash recovery recovery-TWRP-3.4.1B-0313-XIAOMI10-CN-wzsx150.img` - TWRP flashed ok (I also tried other version include one specified in this thread: Ultimate guide to install stable or Dev rom from Xiaomi.eu)
Boot to TWRP
Format (not wipe) data: re-create FS (i.e. create ext4 FS) and format.
Copy `xiaomi.eu_multi_MI10_20.6.18_v12-10.zip` to device (or use external OTG storage)
Flash it successfully
Copy Magisk 20.4 to device
Reboot to TWRP and flash Magisk
Wipe cache
Reboot to OS
Pass first-time setup, install apps
Reboot couple of time to ensure everything works
Any idea what happens? I ab actually ran out of idea - it is not first phone I am reflashing and not the first Xiaomi device (before used Mi 6 reflashed with LineageOS for about 3 years) and it is first time I see device has probably corrupted data/system partition.
One note: after booting to flashed device I setup fingerprint and pattern for unlock. After reboot when phone cannot boot into OS TWRP doesn't ask for pattern (while in normal situation is should, latest TWRP how to unlock with pattern). It makes me think that at the boot moment partitions already corruppted.
Do that for clean installation:
flash fastboot rom (https://mirom.ezbox.idv.tw/en/phone/umi/) China Stable
when phone is open, shutdown. open fastboot and flash this recovery (https://androidfilehost.com/?fid=8889791610682877442)
in advance wipe section select dalvik, data and internal strorage then wipe
reboot to recovery again, in wipe section do Format Data, then reboot to recovery again
connect pc, put latest eu rom zip to phone then flash
restart and do the first setup
reboot to recovery again and flash Magisk

Can't get root back on SHT-W09 after installing latest Magisk

All,
I'm looking for suggestions on how to restore root to my Huawei MediaPad M5. I recently updated Magisk to stable Manager 8.0.7 and Magisk build 21.4. However this caused me to lose root on the tablet. The tablet is on Android 8.0.
To restore root, I tried the following steps:
1) Downloaded Huawei tablet image 8.0.0, build 200, for the SHT-W09 (C567) USA model
2) Extracted Ramdisk image and copied over to the tablet
3) Opened Magisk and selected Download and Patch File
4) Magisk patched the file and saved it in my downloads folder
5) I then transferred the patch file back to my pc
6) Opened my Fastboot folder that had the patched image
7) Booted the tablet into fastboot mode and tested with command "fastboot devices"
8) After verifying I had a connection, I typed "Fastboot flash ramdisk patched_boot.img"
9) The file was flashed to the tablet
10) I rebooted the tablet, but I still don't have root
Any ideas, do I need to use the command "fastboot flash boot magisk_patched.img"?
Thanks,
Rick
Rick,
I managed to root my CMR W09 C567 EMUI 8.0.0.200 by flashing this older version of Magisk directly within TWRP:
Release Magisk v20.4 · topjohnwu/Magisk
Miscellaneous This release is mainly focused on stability and bug squashing. Please be aware that MagiskHide is no longer enabled by default. Since Google has enabled hardware-based key attestation...
github.com
It does all the work of patching the boot file withing TWRP, and when you reboot into system, there will even be a Magisk apk already installed. Do not upgrade afterwards.
The TWRP that works for me is:
[RECOVERY][UNOFFICIAL] TWRP 3.2.2-1
This is for the Mediapad M5. NOTE: Decrypting data is not currently supported. MTP also does not work, but you can use adb to push and pull files. Team Win Recovery Project 3.x, or twrp3 for short, is a custom recovery built with ease of use...
forum.xda-developers.com
The command to flash:
./fastboot.exe flash recovery_ramdisk TWRP-3.2.2-1-MediapadM5.img
PS. You evidently need to have an unlocked bootloader. Mine was locked, but I managed to use the test point method and PotatoNV program. This requires removing the screen (I busted mine--had to replace from AlixExpress).

Hello zentico, is your M5 model SHT-W09?
I have a similar issue: after upgrading my SHT-W09 to latest 9.1.0.360 firmware I patched the recovery_ramdisk-image with Magisk v23.0 and it didn't boot :-(
I was able to pach the same image for recovery mode but in that case I had only limited root access. The only solution I found up to now: using the "old" patched recovery_ramdisk.image which was patched with Magisk v20.4
Edit: looks as if there are existing several C432-360 images. I got the LGRP4-OVS as this was the only version available on firmwarefinder but my device identifies as "P2" most likely that's the reason why it's not booting.

Hi!
I have the exact same tablet, but I'm unable to find the full update to patch magisk and root it fully, where/how were you able to obtain the full ota and extract the image?
Mine is SHT-W09 8.0.0.200(C567)
Thanks!
