I want to unlock bootloader using fastboot for GSI rom. I did everything but once i try to unlock it doesnt do anything. I run fastboot flashing unlock but it goes with: FAILED (remote: ‘unknown command’) fastboot: error: Command failed. I made sure the phone is connected to PC, i have enabled OEM unlock and USB debugging, i dont think im doing anything wrong. I tried the MIUI app, but it just doesnt send me the code. Any help?
