Sorry, i’m a new to this and did not know it.

I have another problem while testing:
My ROM has no wireguard-support so I had to compile myself.
Dirty flashing back to original (AICP) ROM caused stock on the lockscreen.

Is there any option to force android to use the userspace-version to test both version without erasing the whole flash?
What files should i remove in order to avoid the lockscreen issue?

Thank you in advance,

Robert
