How to wipe MIUI theme settings without format data & resetting phone?


Aug 8, 2011
Mi 9 SE - After I upgrade from MIUI 11 weekly to 12 weekly I have a problem the notification panel background is gone. invisible transparent.

In miui 11 I used a custom theme.

I tried to change to default miui 12 theme but the problem bug still not fixed.

I have root access. Can I reset or default the MIUI theme but not wipe the whole data?
