i updated to iOS 7 when beta 2 was released and have never really had a problem, but then about two weeks ago i restored it from the ipods settings so it would stay ios 7 as i was having problems with music.i then got the activation error that im sure you all know about so i connected it to iTunes and put it in dfu mode and tried to restore it to 6.1.3. i have the right ipsw and everything but i cant get it to restore, ive looked at nearly every you tub video on it but nothing works.
