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.

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.

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 guys. A while back I bricked my la1 and found a lx1 rescue box (which worked). However I would like to update it to emui 8 single sim for the la1 and can't because of my oeminfo being for lx1. I have the update.app for the new firmware and have installed honor 8 oeminfo (PRA-LA1) on my Huawei (PRA-LA1). Not sure what I should flash from the update.app as there are different img files from the usual recovery, boot, cust etc.

You can't update to a newer version of Android using the update.app... the device will refuse the package and it will fail ...you have to wait until the OTA update arrives.

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 ?
In the searching for an EMUI5 firmware I have stumbled upon an EMUI8 one that my phone can have installed, I got this from the Firmware Finder:
Code:
Firmware approved for install
Build: PRA-LX3 8.0.0.360(C605)
Also there are other that says FULLOTA-MF-PV, FULLOTA-MF or just FULLOTA, which one should I use?
Now, in Multi-Tool I have an option to "Unbrick" the phone by flashing several images, can I use that to also flash a new firmware, in this case EMUI8? Though I haven't found a boot.img file when I extracted the update.app file. Even if I shouldn't use Multi-Tool can I extract the update file with Huawei Extractor and then flash everything with fastboot commands?
I can't access erecovery because in the past I have flashed something there (that's why I was looking for a EMUI5 firmware, so I could restore the stock recovery), I can only access fastboot&rescue mode, when I tried updating the OS from the phone itself (I had an update that said it includes May 2018 security patches) it rebooted to an error message. I have everything unlocked in this phone.
So i just Got the REALME UI 2.0 update via System Updater and i downloaded is IMMEDIATELY.
But when i tried to install it via ORANGEFOX RECOVERY. It gave me error saying "this Package is for RMX1931L1" and couldnt install on this device.
Can please someone explain what it means, and how can i install this package.
EDIT. 1 : First i installed unofficial TWRP
than i installed C.38 ozip to get Stock recovery than i Relocked Bootloader (which wiped everything internal memory and everything) than i rebooted and checked for update. Got the A11 update downloaded it and Flashed it.
And now i am on A11 stock Locked bootloader and Working Fine.
BTW i live in INDIA
I think you're going to hard brick your device if you've got the bl unlocked and try to flash the official update through OrangeFox. My suggestion is to move the ota file to your pc, relock the bootloader if you're on rui1.0, then move the file and flash it clean, with the bl locked.
How did you even get the update, where do you live?
