im willing to test it out ive been looking for something that changed the notification background and stuff for ages because moar wont change it and whenever i try to change it myself by just adding a new one and changing the name to what its supposed to be it doesnt work but which one should i use LP or KK? the LP one looks like its for 5.1 thats the only reason i ask and im on 5.0
It should be the LP one.
If that's somehow wrong, the worst case from an incompatible Xposed module is a bootloop, and you fix that by getting into Safestrap, choosing file explorer, and creating a file called "disabled" in /data/data/de.robv.android.xposed.installer/conf/
Alternately, there's a flashable zip file somewhere that puts the "disabled" file where it needs to be
Then you reboot, get into Xposed and turn off the offending module. Then use a file explorer to go delete that "disabled" file and reboot.
If you run Wanam and GravityBox simultaneously, you'll probably end up with two battery icons next to each other, but there shouldn't be any catastrophic effects.
