Huawei Mate 8 Test Key?

I re-rooted my cell phone a few months ago and as I'm, I have of course managed to delete the entire operating system. 😉 After a few days, I finally managed (by rolling back to Android 4) to make my phone functional again.

However, I have now only one test key and somehow not come back to the original firmware.

Here is some information about my mobile:

Model: Mate 8
Manufacturer: Huawei
Android: 7.0
EMUI: 5.0
Build number: NRD90M test-keys
Model Number: NXT-L29
OEM unlock: disabled and grayed out
FRP: locked
Bootloader: unlocked
TWRP: not installed

I hope someone can help me and would be very grateful!

Yours sincerely

Elias

Install TWRP
Install Android or Cynamoigenmod

Originally download Samsung firmware and install it via Odin

You can get Roms from sammobile.com

I keep getting this error message:> fastboot flash recovery twrp-3.0.2-0-next.img target reported max download size of 471859200 bytes sending 'recovery' (22020 KB) … OK [0.626s] writing 'recovery' … FAILED (remote: Command not allowed) finished. Total time: 0.637s

Sorry for the bad formatting. On the cell phone that does not seem to work so well.

Take odin and install the download mode for ne rom
