    • This upgrade method will erase all the contents of the phone, please be sure to backup first.
    • The Rollback build should be installed twice. In the first installation, it deletes a few system apps. So you must follow these steps twice to install it a second time.
    1. Download the latest ROM upgrade zip package from the specified server.
    2. Copy the Rollback package to the phone storage.
    3. Go to Settings -> System -> System Updates -> Click top right icon -> Local upgrade -> Click on the corresponding installation package -> upgrade -> System upgrade completed to 100%.
    4. After the upgrade is complete, click Restart.
    5. Update successful.

    Want to go back to Android 10? Download the Rollback package from the links below:
