This Method seems to work only H83020a firmware version(Link). So if your phone is running on H83030c (Oreo 8.0) Latest version, then you need to flash H83020a version.
Download H83020a KDZ file and after downloading this file use Uppercut Tool and Choose Upgrade, after that click on flash.
Before any operation, you must take backup and do on your own responsibility because you can not hold me responsible for any loss.
