Hello.

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
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

After converting to dual SIM you can upgrade to Nougat via TWRP, unpack B370 onto SD card, then flash update.zip file, go back to main TWRP menu and flash second file ...hw_eu.zip. Reboot system. Use TWRP 3.0.2-0 .
But converting to dual SIM may cause problems with next system updates, includÃng OTA and Firmware Finder (IMEI and infos in partition Vendor).
You can try also this solution bellow, with this method you can choose firmware, wichever you find most convenient :

It works fine (self experience). Good luck!
EMUI 8 works great on Honor 8, But if you're not interested in it or any other treble ROM and you want to go back to EMUI 5.x, here's the easiest method.
Just go to eRECOVERY and select "Download and Recovery". Connect to your WiFi and it'll automatically download the Stock ROM and install it. No Hassle.
Note: I only tried this on Indian version of H8 (FRD-L02). And you'll need to have EMUI8's eRECOVERY, which you'll already have if you tried EMUI 8 or any other Treble ROMs.
Finally eRECOVERY has some use!! :highfive:
