EDIT: Hey guys, so since the previous post I have tried numerous things - most notably manually flashing the system, boot and recovery images directly with fastboot. While I was able to do this (using B361 and currently B320) the phone got stuck in a bootloop even though the official recovery successfully did a factory reset and cache wipe. I am fairly certain that if I can get the rollback image to flash I will be able to revert back to stock - but currently this is proving to be difficult. Flashing the rollback image directly with dload fails and I'm currently considering flashing the image through fastboot. Checking the image on firmware extractor tool shows the following:
CRC
CURVER
EFI
RECOVERY
RECOVERY2
VERLIST
VERSION
What extracted image will I be able to flash through fastboot? Thanks for any help in advance
Hey guys,
Firstly I have read through and tried all the usual methods of trying to get back to stock (MM or Nougat) after upgrading to B361. I am currently unable to flash any images through the dload method (not rollback, not nougat, anything). What I've tried flashing (all failed):
L19C185B361 (full)
L19C185B220 (full)
L19C185B210 (full)
L19C185B320 (OTA)
Official rollback image
This is the path I followed:
L19C185B210
MM LOS
L19C185B220
L19C185B320
L19C185B361
(Tried to reflash L19C185B361, failed)
Rollback, failed
TWRP L19C185B220, messed up system partition
Rollback still failed
L19C185B220 still failed
L19C185B361 still failed
Currently running a TWRP flash of L19C185B321, a beta leak image that doesn't work properly
The TWRP running is the Nougat TWRP (MM TWRP not working) leading me to be believe that there is still an official Nougat presence somewhere on the system. I hace an unlocked bootloader, fastboot and adb access but no root. Any help will be greatly appreciated as I've been struggling for over 10 hours now.
Bump - changed the thread question in the hope of getting help
Hello Guys,
It's now possible to downgrade P10 Plus from Oreo to Nougat
Disclaimer: I'm not responsible what happens to your device or if you active some nuclear missiles in the process
Prerequisites:
Oreo Firmware on your P10 Plus
Nougat Firmware for P10 Plus
HWOTA 8 from mankindttw https://forum.xda-developers.com/mate-9/how-to/guide-mate-9-flash-oreo-update-package-t3699522
Rename the files according to this guide:
https://forum.xda-developers.com/mate-9/how-to/guide-mate-9-flash-update-package-t3593108
Access to fastboot and adb
Downgrade Nougat
A. Put update.zip, update_data_public.zip, and update_all_hw.zip files into HWOTA8 repack directory.
B. Run repack.bat to update zip files.
C. Go through "Flash Update" steps and use repacked zip files.
D. Enter recovery and do factory reset.
Flash Update
A. Use Vol-Dn + USB Cable to boot into fastboot mode.
B. Use Replace_Recovery.bat in HWOTA8 to flash TWRP recovery.
C. Disconnect USB cable, use Vol-Up + Power to boot into TWRP.
D. Create "HWOTA8" directory in MTP sdcard.
E. Put hwota8_update.zip, MHA_RECOVERY8_NoCheck.img, and three huawei update package (update.zip, update_data_public.zip, and update_all_hw.zip) files into "HWOTA8" directory.
F. TWRP install sdcard hwota8_update.zip, it will reboot and install update automatically.
Hi!
I got this message when I flash the repacked (L29C432B164) zips with HWOTA8: "Software install failed! - Failed to check the update files. - Please download the package again."
Whats wrong? I've followed these steps, but it failed.
When I put Oreo .311 zips without repacking, but renamed (tutorial) in the HWOTA8 directory on my sdcard and install [hwota8_update.zip] with twrp it installs normal incl. verify BUT there is no change. Everthing is like before.
On my P10 (normal), after a factory reset with .311 it's now on build no. 8.0.0.046(01BN).
I cant downgrade to nougat or update back to .311
What can I do? Any suggestions?
Downgrade work only with rollback firmware like B217

Ok, than I have to wait or is there another way to leave the 8.0.0.046(01BN)?
There is a rollback firmware on firmware finder.
Gesendet von meinem VKY-AL00 mit Tapatalk
Do I need to install the rollback with firmware finder, manually flashing the zips with twrp or with HWOTA?
Install the rollback firmware via proxy in FF

Vtr is not vky therefore it's P10 not P10 Plus
Why I cant repack ?
Downgrade Nougat
A. Put update.zip, update_data_public.zip, and update_all_hw.zip files into HWOTA8 repack directory.
B. Run repack.bat to update zip files.
C. Go through "Flash Update" steps and use repacked zip files.
I run "repack.bat" from Windows 7 it says the 7zip.exe are not compactible, any suggestions ?
How the repacked zip files loock like? I have downloaded the C432 Roolback firmware from Firmware Finder, must I repack them to ?

Rollback contains 3 zips, I think just 2

You didnt answer me on my Question
Becouse a lot of user dont understand and get confused I have made a new tutorial for Rollback from Oreo B321 C636 P10 plus, to Nougat VKY-L29 C432 B181 or other region like C185 or C636
BE CARREFULL AND READ THIS - Do exactly like this description and you will not fail
If you read 2 files , dont aske "can I use 3 files" , becouse there is writen 2 files
Also dont aske can I use "this" or "this" becouse you can only use this what is written and than you have no error.
For Rollback from Oreo B321 C636 P10 plus, to Nougat VKY-L29 C432 B181 or other region
like C185 or C636
What you need:
Access to fastboot and adb or Minimal ADB and Fastboot installed on computer( in root C: )
HWOTA8 from mankindttw https://forum.xda-developers.com/mat...ckage-t3699522
Nougat Rollback Firmware for P10 Plus
I used this firmware becouse I have a 432 model:
VKY-L29C432B181 ( its a rollback for C432 on FirmwareFinder ) only 2 zips or
VKY-L29C432B185 ( its a new rollback for C432 on FirmwareFinder will lock bootloader ) only 2 zips
update_full_VKY-L29_hw_eu.zip and update.zip
Extract the downloaded HWOTA8_2017110501.zip to C: on Computer
Now Create "HWOTA8" folder in EXTERNAL sdcard, in this folder put only
from the extracted HWOTA8_2017110501.zip this 1 file:
MHA_RECOVERY8_NoCheck.img
also this 2 files from downloaded firmware:
update.zip - dont rename
update_full_VKY-L29_hw_eu.zip - rename to - update_all_hw.zip
for VKY-L09 instead of update_full_VKY-L29_hw_eu.zip you download the update_full_VKY-L09_hw_eu.zip and rename as abow described
and this moded - hwota8_update2.zip ( downloaded here as atached file )
It is moded so you need only 2 firmware files for Rollback and NO need to Run repack.bat to update zip files.
SO LETS GO
ON PHONE Use Vol-Dn + USB Cable to boot into fastboot mode.
flash TWRP8_3.0.3.img > comand: fastboot flash recovery_ramdisk TWRP8_3.0.3.img
we use this TWRP becouse it is in HWOTA8 ectracted folder
Boot into TWRP and install from external sdcard hwota8_update2.zip, it will reboot and install update automatically.
After reboot you have Nougat B181 or B185 ( depend what you chose ) on VKY-L29C432
Thats How I did it in 15 minutes
Yes If you have another model not C432 you must download the 2 firmware files for your model region
I'm not responsible for any bricks.
If you fail you didnt follow exatly the tutorial
Reading is the Mother of Knowlege.
Woow Great Thank you

MHA_RECOVERY8_NoCheck.img file is fo Mate 9. It is the reason of my hard bricked Mate 9 Pro. It even doesn't support Mate 9 Pro; how can you think that it will fix your case?
Just try rollback otherwise wait for Official release of Oreo.
This worked fine for me,it took just over 10 mins and I'm back on nougat. I'd previously been on stock Oreo (rooted) and treble (I have a p10 plus VKYL29)
Hi all,
I am on a P20 Pro EU Version (CLT-L29 C432) with firmware 106.
What I wanted to do is update from 106 to 107. I have:
- unlocked bootloader
- TWRP installed (tried with official and Pretoriano80 version {https://forum.xda-developers.com/huawei-p20-pro/development/recovery-twrp-3-2-1-0-t3779400})
- Huawei Firmware Finder
- Patched bootloader from here as well back when the only possibility to install magisk was via patched bootloader (self-created from 106 boot img)
What happened so far is:
1) got the official update notification -> small OTA install failed -> received full update -> failed
2) tried install via TWRP with downloaded OTA from https://forum.xda-developers.com/hu...rmware-release-clt-l29-8-1-0-107c432-t3779167 -> tells me zip is corrupt (=failed)
3) install via twrp and select update.zip in Huawei Firmware Finder folder -> zip corrupt -> failed
4) installed via dload method - tried small and large update file --> "Software install failed"
so yeah. i dont really know where to go from here and the google maps issue is really bugging me, so i def want to update
appreciate any help
OTA fails = you have TWRP installed
TWRP installation fails = TWRP cannot install these OTA files (what I know of)
Install orig recovery and use the FF proxy method.
thanks @fregor - do you by any chance know where I could download it? I could only find firmware files
use the initial method download the ota unzip it put it in folder named dload and proceed to the update by turning on ur phone while pressing both volume keys
just tried with the 500mb ota and get a "software install failed"
will try with the big one if i somehow find the DL location of it
alright man, I have downloaded the full update via FF. when i unzip the "update.zip" i always get a file is corrupted error. happens on mac and on windows :/
AND downloaded it from here http://pro-teammt.ru/firmware-database/?firmware_model=CLT-L29C432&firmware_page=0 --> software install failed again
kinda lost now tbh
thank you all for your assistance - what helped in the end was using zxz0o0's tool HuRUpdater. It flashes FULL official firmwares without the online check. Can be found here: https://forum.xda-developers.com/honor-9/development/tool-flash-official-firmware-recovery-t3769279
i need help to unbrick my p8 lite 2017,
to start my phone was with "cust c555 pra-lx1 emui 5.0.1"
my initial idea was to debrand the phone, but all the guides I tried failed, always returning to the original ROM stock,
then i backup my oem info image, custom.bin and build.prop...
then I wanted to change the method, trying to install oreo emui 8.x, with this guide: https://forum.xda-developers.com/honor-9/development/tool-flash-official-firmware-recovery-t3769279
but result was failed, (I only have a doubt, when I was downloading the zip file hueuupdater via twrp I was doing it from the elite twrp and not from the twrp nochek oreo.....)
* last attempt was flashed via elite twrp an oem info file img (of a fw base nougat nobrand, corrected for my model pra-lx1)
after having opened the file oem, the problems have started, the phone does not go in fastboot mode, it does not go into e / or twrp recovery, it turns on and always restarts, I tried to flash a fw using the dload method but it does not work, I tried to reinstall the fw via erecovery using the wifi but does not start, always error .". Getting Package Info Failed"
now I really need help to restart the phone, someone is kind enough to help me or suggest a proper guide, to unbrick my phone?
thank you
i solved with correct oem info eu!!
Try Firmware finder for huawei + erecovery method , which is :
- download firmware finder on *another android phone* and search for exact phone model (ex : PRA-LA1C185)
- choose the very first firmware down the list
- Get an update thorugh dns >> Manually >> Register update
- After that , reboot your bricked phone into erecovery by ( power + volume*+*)
- press download recovery and last firmware
- wait till getting package
- by now should firmware start downloading
- let phone complete it's work and reboot
Hope that's work for you ?
I've managed to revert from the LineageOS 17 back to stock firmware after a lot of trial and error. I had not been able to find anything on this site detailing this so in the spirit of giving back, here's what I did to revert back to stock firmware. I accomplished this on a BAH-L09.
TWRP must be installed. I did this with twrp_3.3.1-0.img.
Boot into recovery mode.
Grab this firmware: Huawei MediaPad M5 lite BAH-L09 hw ru BAH-L09C170B271CUSTC170D001Firmware7.0.0r1EMUI5.105014LUH [androidhost.ru].zip
Extract the multiple archives inside of the zip file (including the .tar) with 7-Zip until you have the Update.APP file.
Use the Huawei Firmware Update Extractor (HuaweiUpdateExtractor_0.9.9.5.zip). Drag the Update.APP file into the interface and extract all to a location.
(Note: This just hung at the end but I was able to use the resulting IMG files)
Copy VENDOR.img, SYSTEM.img, BOOT.img, RECOVERY.img to an SD.
In TWRP, install/flash the corresponding IMG files. RECOVERY is vital.
Wipe DALVIK/Cache.
Power off.
Restart again into Recovery, this time it will be EMUI/Huawei's recovery.
Factory Reset/Wipe; Wipe Cache.
Your tablet should now boot into stock firmware.
This is how I managed to get back into stock firmware. I attempted these steps with Huawei MediaPad M5 lite BAH-L09 hw eu BAH-L09C100B270CUSTC100D001 Firmware Android 7.0 EMUI 5.1 05014LSM [androidhost.ru].zip to no avail.
I hope these steps are helpful to anybody who requires the stock firmware. Don't forget that you can effectively unbrick your device this way if you can access fastboot and flash the recovery partition (fastboot flash recovery twrp_3.2.0-0.img).
