I can enter fastboot mode and try to do something from PC(Linux) but nothing working. I had tried to format cache and userdata but it throws error
FAILED (remote: not support on security)
I read sowere i have to check some device's settings using
fastboot oem device-info
but it only prints 3 dots in terminal and does nothing. Same if i'll run something like
fastboot oem mbotnrobmotnhomb
Tried to repeat everything with sudo but nothing changed. USB debug is on. What could be wrong with device or PC and can it be fixed?
