TWRP works in ONEUI 3.1. I flashed it but after it boots to the system and I reboot it or shut it down I get only official binary are allowed to be flashed, and I have to go back to stock. Latest U3 Android 11 M31S. Do you have any kernel for this model?

Hi ,

Thanks a lot for the TWRP support.
Although I'm able to successfully complete all the above steps , once i boot into system KG state is triggered and i end up getting the error "Only official released binaries are allowed to be flashed".
and the device goes into KG state = prenormal and its locked for 7 days.
i also tried flashing RMM_Bypass_v3_corsicanu , but no luck as it is throwing ERROR : " cant mount /system_root .... aborting"
(currently M31s is running on Android 11)
Kindly Help.
Thanks

You don't need all this hassle just connect to internet and open browser then check kg status, must be checking.
