I have been trying to install an Android 13 GSI my Nokia T20 WiFi tablet (Model TA-1392) reached its final update ever. However, in order to flash the GSI onto the tablet, it said that I needed to unlock the bootloader to do so. That hasn't been working either, as it gives me this error:
(remote: 'Unlock bootloader fail. fb_verify_unlockkey')
Help? Many thanks,
Saturanium Update: The only command that I could use that did not register as an unknown command was
oem unlock
; which registered something other than
(remote: 'unknown cmd.')
