EMUI 10.0 / Magic UI 3.0 (Android 10) can now be rolled back to the official version of EMUI 9.X / Magic UI 2.1 (Android 9) using HiSuite, without downloading any intermediate packages. To ensure that the rollback succeeds, read the instructions carefully and perform the steps as instructed.

The following are precautions for roll-back.

Rolling back to an earlier version will erase all data on your device. Use an SD card, computer, or Cloud storage to back up all important data before rolling back your phone, and make sure all backed up content is complete and effective.。

If HiSuite is installed on your computer, click the version number in the lower left corner of the page to check if it is the latest version. Make sure HiSuite version is 9.1.0.303 _OVE or above.

Before rolling back the phone, make sure your phone has not been upgraded using non-official updates. Otherwise, the roll-back may fail and unknown issues may be introduced.
