1. Enable Developer Options by tapping the MIUI version (or Build number) seven times in Settings > About phone

2. Navigate to Additional settings > Developer options and toggle on both USB debugging and OEM unlocking

3. Boot the phone to fastboot mode and connect it to a PC

4. Run fastboot oem unlock-go

5. The phone would reboot and you'll see Unlocked message on the screen

How to enter flash mode

Press and hold Volume Down + Power until you see a fastboot logo on the screen.

Follow the Installation guide and your device wiki page.
