Thanks a lot for this! Helped me with OOS 9.5.4 on OnePlus 7 Pro.

Yeah! For me too with OnePlus 7 Pro!
Btw if anyone used a guest user, he should change number 999 to 10

I tried the su command under emulator but it says "su: not found" is this because I am not rooted?

Yes.

This worked for me.

looks like it's an error with parallel apps oder multiple users. since i do not use something like that, i just removed this user with the android terminal emulator:

su
pm remove-user 999

everything was fine after that

I upload android10 to mimix3. I uploaded settings and made copies of TWRP. I wanted to restore copies and error 255.
I found a way to fix the error on the internet.:
I have installed: twrp-3.3.1-17-perseus-mauronofrio.img
Ok. Let start. Install from Play store: Android Terminal Emulator.
Open Terminal and type:
$su (hit Enter)
#pm remove-user 999 (hit Enter)
Should come up: Success: removed user

And now i have problem with USB. Camera and other applications show: mount USB.
What can I do next?
