Hello there ! My S20 (SM-G980F/DS) device runs BeyondROM (A12, OneUI4). Can I wipe and install LOS 18 on it ? If not, how would I downgrade to OneUI3 ? Thanks !
You don't need OneUI 3. I successfully flashed this on Oneui 4 just fine. Besides, sboot makes it almost impossible to downgrade. 120hz works like a charm.

    FAQ

    Reporting Bugs
    DO NOT Report bugs if you're running a custom kernel or you installed Xposed
    Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)
    If it is a random reboot, grab /proc/last_kmsg. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)
    If the problem disappears after running "setenforce 0" from a root shell, grab /data/misc/audit/audit.log

    Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. Please also do not report known issues. Any bug not reported in the bug report format below may be ignored.
