Hello,

I had my Mate 8 NXT-L09 with Nougat but I had the TESTKEYS version, I used a rollback package and then installed an old ROM and my phone went from being a nxt-l09 to a nxt-l29 and I can't upgrade.

Device NXT-L09
Location Movistar Ecuador

Had TESTKEYS nougat version upgraded using Firmware Finder.
I now have NXT-L29C432B170 and update fails.
I think I'm with version NXTC900B100

I have no TWRP Backup

Anyone knows how to solve this? I might be able to call Huawei Ecuador and get the required files, I have a VIP card if it matters..

I had the same problem but I managed to solve it. I would explain how to do it but I'm too lazy to write it in English.

I speak Spanish
