Today, MIUI announced in the community: In order to maintain system stability and ensure the security of the device, the recent Red Rice 6 Pro introduced the 'anti-rollback' mechanism. MIUI domestic development version 8.7.30 and above and stable version V9.6.16 And above, will not be able to downgrade back to the old version of the development version or stable version.
If you have previously updated your phone to version 8.7.30 and above, or stable version V9.6.16 and above, please don't try to downgrade and brush back the old version, which will cause the phone to brick.
Before the Red Rice Note 5 introduced the 'anti-rollback' mechanism, the Red Rice 6 Pro is another model of Xiaomi that does not support 'rollback'. In fact, Google built a built-in Rollback Protection in Android 8.0 system. (rollback protection) security feature that prevents the device from rolling back to the old firmware version.
According to Google, the reason why the 'Rollback Protection' function is built in the Android 8.0 system is mainly due to the comprehensive consideration of the security of user data information. After all, there is a high possibility of security vulnerabilities in the old version of the Android system firmware.
