The phone has a custom firmware MIUI 10, instead of the factory Android 9.0
Now I'm trying to set myself root rights. I go into fastboot, enter the command "fastboot boot" - an error. "fastboot divices" - displays once, I write a second time - a black screen with the text "Press any button to shut down". I can't use unlock_critical
fastboot flashing unlock_critical
FAILED (Write to device failed (Unknown error))
fastboot: error: Command failed
When I tried to lock or unlock the bootloader (once it miraculously happened to do it) again an error.

When trying to lock:
fastboot flashing lock
FAILED (Write to device failed (Too many links))
fastboot: error: Command failed

When trying to unlock:
FAILED (Write to device failed (Unknown error))
fastboot: error: Command failed

If I try to install something (for example, download an image) again mistake. As a result, I can not do anything, because the black screen after each command. What to do?

It is not clear why he had to change the firmware at all.
Recently, I have this model updated to Android 11
, put another launcher instead of the poor Google one and enjoy life
. But in general, yes. on w3bsit3-dns.com now
