P9 lite rollback problem

Hello sir
I lost my Bluetooth keyboard and many other apps and setting after rollback Huawei p9 lite by vns l21 c185b300 firmware
Hello,
i bet you flashed wrong package when you update FROM rollback package...
I mean you have to download FULL-OTA correct package size.... it's like 1.7/1.9 gbytes or something similar.. (not the smallest)
Dload method again and see if all working now..:fingers-crossed:
Best regards..
P.S.: firmwares that ends with 0,2,4,6,8 are for dual sim,
firmwares with 1,3,5,7,9 for single sim (example VNS-L21C185B150=dual sim/VNS-L21C185B151=single sim)

Undo Rollback P9 lite?

About a year ago a did a rollback on my Huawei P9lite from Android 7.0 to 6.0. Now i want to update it back to the latest version available.
The phone won't do it automatically and I also can't find the right package online to do it manually. Does anyone have some advice on how to do this?
The current build is VNS-L31C900B160 (It also used to be C432 for europe instead of C900)
The phone hasn't been tampered with aside from the rollback.
Thanks in advance
Jenson

Will a factory reset help? Or will I still be stuck on C900?

P10 Lite (WAS-TL10) Stock ROM files

Hello all,
I'm looking for the stock rom (EMUI 5.0/Android 7.0) firmware files for my newly acquired P10 Lite (WAS-TL10).
Bought it at AliExpress, was supposed to ship with Android 7.0, but got Android 8.0 on it.
Unfortunately I need Android 7 for the sole purpose of verifying some Huawei allegations in which they pretend my app is not working properly with HMS Core version lower than 2.5.3! A version you can't find anywhere on any devices, but those Huawei phones running Android 7.0!
I say they pretend because they've made-up all kind of new rules for the past months to just prevent my apps from being published in China, as explained here: https://www.3c71.com/android/?q=node/2784
Any help would be much appreciated.
This is the only Android 7 Stock firmware I could find:
Huawei P10 Lite Dual

Thanks but the download link doesn't work at all. I've found hundredth of such links but none works. This one ends-up with 'an error occured'.
Is it the same for you or are you able to download the file?

I'm sorry, I should've checked the link first, it seems like these files were removed from Huawei servers, however, there's AFH which, luckily, has the nougat firmware.

Try to downgrade to Nougat using Hisuite (official and safe way to do the downgrade). A7 firmware will not help you, there's no way downgrade (with locked bootloader) . Try chinese Hisuite :
https://mega.nz/file/1p9xyIRL#bx1M6zXqtrR38okQd4YqkYvmLfRaOBDJ2snjd8W7kqk
If the rollback option is not available with your HiSuite ("switch to the older version" or "Earlier version"), you must downgrade to the lower Oreo build version number doing the dload method (flashing Service ROM for your model and region).
Hi...
Like @-Alf- said you can try it this way. If it doesn't work for you. Search this forum for Service Rom to downgrade from emui 8 to emui 5. But be carefully by using any method. Make a full Backup of your System before doing any change. If you will downgrade to emui 5 for unlocking the bootloader. Better think about to use the Dc-unlocker for that. It will cost 4€ to get the unlock code. But its without risk to brick your device and it doesn't waste time to get it. You need to choose wat is more important for you.
So good luck

Thanks all, I was able to downgrade to EMUI 5.1, which allowed me testing very old HMS Core (2.5.2) somehow and its upgrade mechanism. Not sure I needed that device as it seems EMUI 5.1 didn't come with AppGallery at all, LOL.
Now I'd like to upgrade back to sell the device, but I haven't found a way to do so... Hi Suite tells me device is up-to-date, and OS system update tells me the same

Build number is WAS-TL10C636B187
I found a firmware, but it doesn't seem compatible ( Warsaw-TL10HK 8.0.0.371(C636)_Firmware_8.0.0_r1_EMUI8.0_05014HTC ) because upgrade says there is no update file on SD when I put the dload folder on it.
EDIT: That firmware contained zip files instead of .app, so I extracted the .app files and recreated the expected structure, and it processed the update using OS menu ( *#*#2846579#*#* ).
If any-one need the modified file, let me know.

Have you tried to upgrade via eRecovery & Wi-Fi?

No idea what that is lol.
After modifying the dload folder to have .app files (instead of .zip), the phone took the upgrade (editing previous post). New build number is WAS-TL10 8.0.0.371(C636).
I can now upgrade/downgrade between Android 7 and 8 for testing. That's pretty useful, so thanks to all.

WARSAW is the Name of the Phone...an p8 lite 2017 is called Prague or an Samsung S6 Edge is called zerolte
If you try to flash a firmware with another Region like C432 for Europa on a Device with C636 Asian Region...the verifying of the Update Package will not pass and update proceed will abort.
If you want to change the Region of the Device you need to use HWOTA Method for that...in the Script during configuration comes the Question to change firmware or to change location.
But be carefull by changing the Region cause the Devices for the different Regions could have different hardware integrate. Hardware like modem and so^^
OK thank you, i think modified firmware provided by 3c will work on my device as is has the same code of region c636 and the firmware flashed on my device is Asian pacific (c636)

Jfyi, the Huawei update server is down since February, so Firmware Finder is dead. Therefore, it is also not possible to use HwOTA or HuRupdater (unless someone has the necessary files stored on the disk).
