- Click on additional settings and then enter Developer Options. Activate "OEM Unlock".
- Click "Mi Unlock Status" in the Developer Options. Touch "Add account and device". Add your device for unlock
- Activate "USB Debugging" again from Developer options

- You need to download and install the USB Driver first.
- Download Mi Unlock Tool. Run "miflash_unlock (or mi unlock.exe )" with an orange icon as an administrator. And login to the program with your Mi Account.
- Power off the device. Press and hold the "Power Key + Volume Down" key for 5 seconds at the same time. The "Fastboot" mode will open.
