After a factory reset from recovery my Huawei P9 Lite VNS-L31 with emui5, root and revolution recovery brick.
I tried to install stock firmwares from erecovery, recovery and adb.
Use dload . Or the best way would be using rolback package to go back to mm and from mm use firmware finder proxy to install nugat . It should fix ur phone

First off
I have a vnsL31 p9lite on mm c432b160
Unlocked bootloader and frp
Can flash TWRP, can root, can unroot
Can access fastboot
I have b160 firmware and rollback package
I have b336 update and data hw eu zips
I have the Huawei update extractor
I have Revolution recovery
I have Meticulous recovery
I have EliteKernel
I have the OEM unlock code
I have c432oeminfo zip and oeminfo with a custom.bin
I have hisuite
Phone is working fine
My issue is that I can't upgrade the phone or downgrade the phone to any software at all.
Before my issue I was on b160 and upgraded successfully to b336 and used it for a long time. I then upgraded to b370 using firmware finder successfully. I then wanted to root nougat so I could uninstall some Google apps and tried the EliteKernel method, which didn't work and started going into bootloops. I then tried to downgrade to mm using the rollback package and then flashing b160 which worked successfully.
Then I tried upgrading back to nougat with firmware finder which didn't work, I had missing apps so I did the rollback method again which landed me on nrd90m testkeys. I followed a guide I can't remember to get back to c432 which didn't work either my phone then got bricked. It was stuck on bootloop and vibrated twice each time it tried to go past the Huawei logo. I couldn't access anything but fastboot. I then followed another guide to extract cust,boot,system and recovery images from the b160 update zip and flash those through ADB which worked and have my phone in working order.
My phone now shows build number as vnsl31c432b160 but model number as hi6250. I can't update the phone to nougat or reflash mm to get back to completely stock. Dload 3 buttons method doesn't work for b160 or b336, it goes to 7% then System incompatible error. Flashing the update zips through TWRP doesn't work either, I always get a zip error although it says done but nothing happens.
I want to get back to stock nougat or may even try a custom ROM as long as it is extremely stable. I am willing to root and unroot and do whatever need be to upgrade again. I think I have all the files necessary and should be able to follow any advice given
You must try flashing a OEMInfo for your model and correspondent firmware.. If you want, you can send me a PM with the details of your phone and I'll try to give you the exact files you need to use..
The model is VNS L31, it's dual sim and I'm currently on marshmallow b160 region c432, I bought it carrier unlocked. But the model number shows hi6250 now. I'll try flashing the oeminfo you give me and hopefully it works
This is what I mean, but it is a VNS L31
Hello. I have bricked my p9 lite l21 recently and managed to make it work again hovewer now I have c432b161 firmware and cannot upgrade it further. Huawei ota does not find any updates, i have tried through the firmware finder app but even when the app shows its compatible, it still wont update (vol - + power updater shows information about it not being compatible). I have also tried installing it manually by twrp but the error 7 shows up. I think i have already tried b370, b371 and some others. What firmware should I install now to be able to update it to emui 5?
Hello i have a classic P8 Lite with branded software, and i had a root with kingroot (or something like that) after unroot, the Update app notify me with a new system 300MB update. After download it fails on 19% while installing and reboot back to homescreen. So what can i do if i want a non-rooted android 6? Download B565 (android 6) version via app " Firmware Finder", and try to update? But i dont want to brick my phone... thanks for your replies!
What is your build number?
Ale-l21svkc150b181
You must debrand(change region) to europe that you might have android 6
In 5.0.1 you mustn't have unlock bootloader
Download b170 rom and b524 rollback
Flash in local update
Flash in dload b170 vendor file
Flash in dload rollback b300 file
Flash in dload b170 rom file(2gb file)
Flash in dload b170 vendor file
Download b610 update file europe for p8 lite ale-l21
Install in local update
At the first, i must lock my bootloader again? It is the same like unlocking, but i type relock ?
You have unlock bootloader? No,no may be unlocked
Kingoroot unlocked bootloader, its weird for me too. And i must download B524 and B300 rollback? But why rollback ? I have 5.0.1... and what is vendor file?
Hi friends
I have P9 Lite (VNS-L31) Android 6.0
I want to install official update. I downloaded the package in settigs menu. I'm using TWRP. So update is not installed. I guess I need to use stock recovery. Where can I find it? How to flash stock recovery? Same the flashing twrp?
Yes,you'll have to flash stock recovery before applying your update.
You'll have to find the firmware of your version (B1XX),then extract the recovery using Huawei extractor (available on XDA ),and finally flash just like you flashed TWRP.
I have unlocked the booloader long before.
I have downloaded and managed to reboot to TWRP. (https://forum.xda-developers.com/p10-lite/development/recovery-twrp-3-2-1-0-t3783447)
I have downloaded supersu zip and "flashed" it with TWRP. (https://forum.xda-developers.com/p9/development/root-supersu-2-81-emui-5-t3612258)
I rebooted P10 lite and start supersu app, it told my no ROOT.
The P10 lite is a Janpanse version WAS-LX2J at EMUI/Android 8.0.0.
