Those who updated to EMUI 9.1 Beta Firmwares and hated the EROFS and can't enjoy root can rollback to EMUI 9.0.
I was able to rollback from 9.1.0.135 to 9.0.0.200.
-Download the latest HiSuite.
-Click on "Update"
-Click on Previous Version
- HiSuite will then start to Download the EMUI 9.0 firmware, in my case it downloaded 9.0.0.200. Probably because this is the last EMUI 9.0 firmware.
- One download is complete it will proceed to install the firmware to your device.
- Once complete, you device will reboot to recovery and complete installation.
Note: This process will delete all your user data.
Goodluck!!
