ow i wasn't aware of that, thank you very muchThat's what I am trying to save you, some money! Those guy that say they have authorized Mi accounts are just flashing your phone regularly and then charging you money for it. If you can access fastboot, all you would have to do is either format your internal storage or access EDL by typing in the ADB command <fastboot oem edl> and flashing a stock rom using the MiFlash tool. If your device is accidentally locked, you just need to unlock it again using the MiUnlock tool. These guys claiming to have authorized unlock codes are scam artists!
