Finally, choose a mode between clean all, save user data, or clean all and lock. I recommend clean all and lock in case you just want to upgrade and not make any more modifications to your device in the future. This option will also lock the Bootloader.

Update MIUI!

Now press flash and automatically the process will start, after a few minutes the phone will start and you can use your updated device. Enjoy!

That's it!
That’s it!


Upgrading via Fastboot is a really simple and fast process, as well as safe. I recommend it to those who want to receive early updates to MIUI 12. Bye!
