Hi,
Have been messing around lately, but have bought a new phone now so I want to restore this one to its original stock rom.
I have the L31C432 dualsim version, but after I did a wrong flash, It now stands on L31C900B160.
I want to restore it to a stable version for L31C432...
Phone is unlocked and rooted and have TWRP installed.
(in P9 toolkit I see is it missing custom.bin , local.prop (Pro-Mode & App-Twin , It also says the model is a VNS-L11)
Can anyone help me restoring it please ?
Thanks

Hi all,
i own a p9 lite that was on Nougat VNS-L31C432B381 and i decided to rollback to MM. Following Huawei website instructions I downloaded two packages (rollback package and MM) and with 3 buttons method I flash first the rollback package and then MM. All went right and the ROM was stable. After a while of testing (that's why i went to MM), I decided to upgrade to nougat again. From updater it download and install the new android version (1.25 GB). After reboot I noticed that some system app was missing (file manager first). At every reset/factory reset some system app disappear. I repeated the procedure to rollback and upgrade again with the same result. The only way to use the device was to reflash MM and don't upgrade. Here some information I found:
- my starting version was Nougat VNS-L31C432B381
- now I'm on VNS-L31C432B160 (B160 isn't for dual sim? i have the single sim version) stock recovery bootloader locked
- updater try to install VNS-L31C432B370 (instead of B371?)
- if I try upgrade throught updater SN became something like ndr90 test key
- I tried to restore data,syste,vendor,oeminfo ecc.. from backups made with TWRP in Nougat (maybe wahile i was on MM, I'm not sure). It show the correct SN but ROM was still unstable
- I thought to try install full Nougat ROM but i didn't find any package
Can someone help me?
Thank you
The B37x update that the phone automatically finds after rollback doesn't work and will take you to ndr90 test key as you found out B160 is dualsim so you should flash the 161 one. Then use this guide to update through firmwarefinder/proxy https://forum.xda-developers.com/huawei-p9lite/how-to/how-to-b388-nougat-maybe-b381-guide-t3612072
If you want to unlock your bootloader you can also flash B3xx through twrp. If not, the guide above works fine.

Hi Mara-X and thank you for you answer.
After I write the post i found the B161 package and i decided to give it a try. After flash (all ok) I launched updater again and it download the B371. The update went well and now i'm updating at B381 again throught updater. I think, when it was done, i'll factory reset the device for a clean install. So it seems the problem was B160/161 -single/dual version.
Hey , i need help , i changed my oeminfo with kernel files by missclick. Now when phone is booting red screen appearse.
my build number is ALE-L21C432B614

Edit#1:I fixed that problem by downgradeing my phone back to android 5.0 and then update with OTA
Hello. I have a p9 lite, VNS-L31, which now mounts a twrp elite as recovery. I would like to find a way to go back to the last official version of the huawei (the B405 if I'm not wrong).
Thanks forward ; )
Use the dload method
Use this, 5 min of work and you will have device back in stock and on Nougat ?

Hi, I'm in a sticky situation
I downloaded a custom recovery (revolution custom recovery) and wanted to install lineage 14.1 on my phone. I installed everything properly and still my phone doesn't get past the startup animation. After that I thought it was because of the recovery so I installed I TWRP (which should be compatible) through the existing recovery. And now. I'm stuck between loading screens and don't know what to do. I managed to get to the erecovery of EMUI and charged up my phone. Since I don't want to break anything else I'm asking for help.
Change data partition to ext4.
How yo recover
Flash sotck EMUI rom from consumer.huawei.com using 3 buttons method. You'll be able yo use your phone, but I think Google services doesn't work (in my case) so try again yo flash lineageOS. Good luck

Hello dude, ok you got L31 model phone, but, except for Revolution recovery,
you did not give any more info about the firmware you had before flash custom recovery.
Neither info you wrote about lineageOS and other TWRP you tried to flash.
No one can help you without these basically info, so post here...
Best Regards
Hello there,
I would like to flash a LeaOS - Lineage 18.1 on my P8 lite 2017 (the ROM by @AltairFR) because honestly it looks amazing.
I have a device fully unlocked and ready to be flashed through fastboot.exe
But some part are unclear to me, like the stock rom version that HAS to be installed before the flash.
I’d like to stick to 8.0.0.412(C432)_Firmware_EMUI8.0_05014FSP but honestly the DLOAD method (putting UPDATE.APP on a sdcard then lowlevel restore) has not worked for me and put me
on a weird emui 8 8.0.0.046 version when i use it with genuine Prague firmware and i feel tutorials about this phone are now obsolete to be relevant
With that in mind, i am reluctant to follow the @AltairFR tutorial https://forum.xda-developers.com/t/...ineage-18-1-for-huawei-device-emui-8.4371629/
I fear the phone is going to loop endlessly once newly flashed with LINEAGEOS LeaOS-20230112-iceows-pra.7z
Could you please give me more ideas to prepare my flash worryless ?
I am running PRA-LX1 8.0.0.366(C530) I restored via Huawei eRecovery (cf pictures)
Could you give me more steps (like updating to C432 firmly) please ?
Thank you.
