I try to unlock my redmi 3 pro with mi flashunlock. i have enabled oem unlock, usb debugging and fastboot mode in developer options. i booted my phone in fastbootmode. i have permission to unlock and when i connect my phone to the pc miflashunlock recognizes a mi device next i press unlock and after a countdown it says: Couldn't verify device. can't get info, connect again and gives me the option to try again. Can anyone help me? What am i doing wrong?
