If I enable usb debugging and set usb configuration to file transfer you should be able to unlock your bootloader.as far as flash all.bat if I extra t your miui rom it’s under firmware folder in the extracted folder

Error occured when i was flashing , “Flash tz_a error”.
I highly appreciate your help.
