I have a Samsung galaxy tab 2 7.0 p3110 jellybean 4.2.2 rooted with cyanogenmod 10.1.3 and clockworkmod. I want to downgrade to jb4.1 but never made a nandroid backup of 4.2 to remove cyanogenmod 10.1.3. How can I safely downgrade to jellybean 4.1 without brickin my tablet? I don't mind staying rooted but I'll do whatever is needed to remove this awful jb4.2os.
