MIUI 12.5 System

As we know, in December, at the Xiaomi Mi 11 new product launch conference, Xiaomi first released the MIUI 12.5 system. The MIUI 12.5 update brings much more privacy-centric features, app optimizations, notification improvements and some minor visual improvements. The new skin update also brings a new feature called MIUI+, which enables mirroring your phone to a Windows PC. The MIUI 12.5 is available for the following devices – the Mi 10 series, the Redmi K30 series, the Redmi K20 series, the Redmi Note 9, the Mi 10 Lite, the Redmi 10X series, the Xiaomi CC 9e/CC9, and the Redmi Note 7 series.

Although Xiaomi hasn’t exactly marketed the MIUI 12.5 update as the kind that brings forward interface changes, there have been several tweaks with the Control Center and MIUI Camera, coupled with many new animations. This is quite understandable considering that Xiaomi always wanted to promote MIUI 12.5 as the kind of update that’s keen on improving what’s already on the table and further optimizing it.

Besides all of this, it is quite possible that after updating your phone you may face a number of problems, failures and bugs. So after the release of MIUI 12.5, many Xiaomi phone users are not happy with the performance of MIUI 12.5 and most of them want to downgrade from MIUI 12.5 to MIUI 11.

What If You Can’t Downgrade MIUI Version

We have to accept that you can’t downgrade MIUI version in some smartphones from MIUI 12.5 to MIUI 11. Because Xiaomi decided to stop this option and introduced Anti Roll-Back (ARB) ban. This is also related to Android 10 and the latest changes in Google security policies. Probably, we will see the Anti Roll-Back will be place in every other Android 10 or newer devices, by Xiaomi.

The smartphone which is released after the 2nd half of 2017 might be affected by the ARB ban. This means if you have MIUI 12.5 Android 10, then you can’t downgrade from MIUI 12.5  to 11.

Anti-Rollback Protection

Xiaomi implemented anti-rollback protection in the latest versions of MIUI. Google’s anti-rollback security is a feature of Android Verify Boot 2.0. It prevents the device from booting.

Xiaomi anti-rollback protection

Anti-rollback protection is necessary to prevent attackers from loading older software on a device that’s susceptible to an exploit. The most significant difference between Google and Xiaomi’s implementation is that Google’s anti-rollback protection can be disabled if you unlock the bootloader while Xiaomi’s can’t be disabled.

Once you install a build with anti-rollback protection enabled on a Xiaomi device, you can’t go back.
