Hi, there. I have a note 9 pro, but it's still freeze on miui 12, android 10 and security patch of 2021-03.
I tried with an hard reset to fix the problem but nothing changed. So I tried to unlock the bootloader to make a manual update.
After miflash said to wait the classical week, I tried also with the OEM Unlock feature but the prompt shows me this error:
fastboot flashing unlock FAILED (remote: 'Token Verify Failed, Reboot the device').
Is there something else I can do or try now? Keeping a resetted device for a week is very annoying.
