A noobie queston perhaps, I have seen there are 2 options for the AddOn zip, one is the regular zip and the other is system as root,what is the difference between these two and which one should I download and flash?
A genuine question since I can'...
Try uninstalling the current one and try flashing sdk22 after that.
Everything about xposed for lollipop is on this post http://forum.xda-developers.com/showthread.php?t=3034811 ;post should help a bit.
I think XPosed should work on any bootloader,only depends on the versions that xposed supports but by now it should support almost any android versions,anyone can correct me if I'm wrong here.
