Greetings friends. The new version of the Android-based operating system MIUI 12 released this year, is still being deployed with some devices missing. On many of them, you can already install the update officially via Fastboot. In this post, we will show you how to Update MIUI 12 via Fastboot.
To perform this process you need to have the Bootloader unlocked. You can check our guide by following the link below:
Download MI Flash Tool. MI Flash is the tool you will use to flash the ROM. You can download it by following this link:
Download the ROM for your device, you can do it from
Xiaomi Firmware Updater, select the model of your device and the ROM you want to download. Remember that the ROM must indicate that it is for Fastboot otherwise it will not work. Then extract the file with WinRAR
Unzip the ZIP file of MI Flash Tool. After that, run MI Flash Tool as administrator. Then go to the driver’s tab and press install.
Then press Select to choose the directory where the ROM is, finally press ok.
Shut down your phone manually, and hold Volume down key and Power button to enter Fastboot mode. After that press the refresh button.
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.
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!
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!
