Root access was working just fine a couple of days ago (it was still working after I updated to 2.4.20), and now for some reason, when I try to access TitaniumBackup just now, it says it can't access "/xsystem/bin/su" I tried replacing BusyBox, but BusyBox Installer couldn't get root access. I tried downloading the SuperUser app, and that still can't get root access in TitaniumBackup. I've tried running fix permissions from recovery. Anyone have this same problem? or know how to fix it?
