how did you manage to unlock the bootloader? i get constantly the message "not connected to device" in mi-unlock.
tried with different drivers, in different methods. everything it needs in developer settings is turned on.
still didn't manage to establish connection to unlock..
so it's a fastboot driver issue...
If the phone is not detected with "fastboot devices" there is no way to unlock the bootloader, hence the error you receive
