I've tried every way of downgrading to stock B132 and installing the official B510. No luck. :/

Go to B125 (HuaweiNews or Huaweiblog) then go to B510. You'll have no problems.

Did this with absolutely no hitch. Took 20mins for all firmware versions to be flashed individually.

Unhappy sete01

Installed in B507's ruins I have not returned to the factory B 107 rom tried this three-button dlod mappás variation
from the phone and the ROM update failed!
B 506 - B507 always instalálni.
Unfortunately, the ROM backup is gone, they have a bad SD card.
I would really appreciate if someone could help.
