Can not upgrade to B390 (C432)

Hi,
I'm on C432, unlock bootloader. (It's a debranded phone).
I can't update. to B390.
I did a clean install of B386 using TWRP (flash the 2 zip file, clean cache). B386 works fine.
Update from phone did upload the B390 update, it rebooted into Huawei recovery and it failed at 12%. "Software installed failed".
So I've tried with TWRP (I have downloaded the B390 from Firmware finder) and it fails on update.zip with an error 7.
I've tried various versions of B390 (from Firmware finder) and they all fail when trying to install update.zip from TWRP.
Flashing back B386 with TWRP works (no errors when flashing update.zip).
It seems the update.zip from B390 tries to look for something missing in my phone....
Any ideas ?
Thanks !

Stay on B386 unless you're really keen for the latest security update.
Peace.

I can' t even go back to B182, B383. Only B386 I can install (hopefully). This tells me that something is corrupted in my phone.
I have the following error with TWRP:
assert_failed: block_image_verify("/dev/block/platform/hi_mci.0/by-name/system", "package_extract_file("system.transfer.list"), "system.new.dat", "system.patch.dat")
ERROR 7
With other update.zip, I also have
assert(update_huawei_pkg_from_ota_zip("UPDATE.APP"));
What's wrong in my phone ?

albelushi7 the problem is that update.zip fails with TWRP because of the assert.
I guess the problem is because my VENDOR, PRODUCT, VERSION are probably corrupted (or may be other partitions).
I can't flash them using fastboot.
I looking for a TWRP backup of these partitions for a L09C432 model. Can someone share a backup of these partitions ?
(Even a full backup with B390 installed for a L09C432 would be great !)
Thanks !

I'm going crazy with this. Tried to rollback to MM everything time I try to flash, it fails.
Either by
- TWRP : Update.zip fails with ERROR 7
- Huawei updater + HiSuite
- 3 Button methold and dload folder.
I can only flash B386. It works fairly OK but with some random crashes.
I don't understand what's wrong with my phone. It was an Orange phone, debranded to C432. I had several updates without any issues and problem came since B383.
Could not update with Phone updater to B386. Did with TWRP. But now, I can't install anything. Only B386 can be installed !!!

same thing happen with my phone. now, i use c185 with b390. you should try the same.

So you flashed the OemCust for C185 and it worked ? Good to know !
You were on C432 before ?
Did you try revert back to your original OemCust ?
Thanks !

Hi! I had the same problem. I solved it in this way:
Backup app+data with titanium
Revert to MM with the official procedure, upgrade via updater to nougat and install, always via updater the updtes until B390. Works everything.
The I reunlocked bootlader via adb, install twrp, rooted and restore apps with titanium.
Long procedure, but it worked

How lucky ! I did install MM Rollback and then MM (C432B136). I was on stock recovery and bootloader locked.
Update B136 -> B160 : Ok
Update B160 -> B182 : Failed
Now I can barely install anything (B386 anymore, it used, now it doesn't). Only TWRP...

When I downgraded to MM I was already on b182. I immediately had the nougat update available.

[Q] how to update after rooting (magisk) ?

Hello
I was on B180 (PRA-LX1C432) rooted with magisk
No updates available in settings/update firmware, but connecting to PC HiSuite B194 appeared (which seems to be for Honor 8 lite by the way). It downloaded it, pushed it to phe phone, but when rebooting it goes to twrp... so obviously I'm still on B180
I imagine we have to flash back stock recovery before updating ? And then twrp again, magisk flash, etc ?
Thanks !

About OTA over magisk I found that on P9 forum:
1) unroot by Magisk Uninstaller, find the download link in the post https://forum.xda-developers.com/sho...63&postcount=1
2) flash from TWRP original stock boot img
3) wipe Dalwik and Cache from TWRP
3) flash from fastboot original stock recovery
4) let it make OTA update but select in the System Update settings to use Full (not differential) update - it will not delete your apps and settings
maybe the safest way indeed...
But as I "catch" the full ota, maybe I can use fastboot to flash only system and boot, and the reflash magisk to patch new boot img ?
anyone ?

Nobody updated after root ??

Ok, this is what I did and happened:
- In TWRP, flash magisk uninstaller script: ERROR 1. After reboot magisk was still here. That was a bad start...
- So I opened magisk app, click Uninstall and then Complete Uninstall. After that I made a reboot as asked, and device rebooted twice.
- Then, went to download mode and flashed stock recovery. And reboot.
- Then went to settings/updates/download latest full ota. It downloaded but refused to start the install process claiming to free up more than 900MB... Nothing on my internal sdcard so I had to uninstall some apps... cool !
- Then it reboot and installed the update
- First boot took a while, I still have "this device cannot be trusted" on start, and OEM unlock in settings is grayed and ON, so I think the bootloader is still unlocked
- Theme and wallpapers were reset with the update
For now I don't have flashed back twrp neither magisk .

In the meantime have you flashed TRWP and Migistik ? And again: do you have still to update your signature or something went wrong in installing fw B194.
Lastly: what do you mean by "went to download mode and flashed"...

[HELP][SOLVED] Bricked my P8 Lite 2017

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 ?

Flash stock updates when twrp is installed

I found an easy and convenient way to flash Huawei updates when twrp is installed. No data loss. In my case I updated from June to July patch without any hiccups.
1. Download the HWOTA8 folder zip to your device and extract it to the root of your SD card. I provided the link at the bottom of the tutorial.
2. Download the Huawei update and wait till it finished.
3. Boot to twrp and go straight to the HWOTA8 folder.
4. Now install the hwota8_update.zip, this will install a special no check version of the stock recovery.
5. After reboot you'll see a failed update attempt, ignore the message and boot to system.
6. Now that we have the stock recovery you can go straight to the update app in the settings and install the update.
7. After 5 minutes the update should be finished and the device will boot to system.
8. The bootloader will be still unlocked so you can modify again with twrp, magisk and so on. No data loss.
