Update. It does not work . My freaking phone is bricked:crying::crying::crying:
TWRP works the force update programm too, but my bootloader of the phone is still locked.
Sad that no ones there who can help.
Your Device is FRP-Locked, and that's not so easy to solve, because FRP is Firmware-Recovery-Protection, what specific is therefore that You cannot anymore flash a Firmware! There are many Videos on YouTube for solving, but for that You must be able to boot into System, because FRP-Unlock works over Google! Can You boot into System? - In case not, there is nothing You can do! The only way for recover than is over Huawei-Support!
