Hi,


I try lock backdoor in Huawei Mate 20 (Android10) but after reboot still - FB LockState: UNLOCKED.

fastboot oem backdoor set 1

- not working (Backdoor command not supported)

fastboot oem hwdog certify set 1

- not working

fastboot oem hwdog certify close

- working but the command returns OK and after reboot FB is unlocked


I did downgrade to Android 9 via DC-Phoenix but no change*
