I had been using my Ipod touch 4g when it suddenly stopped working (blank screen). I put it down to a low battery and charged it. This did not seem to work. I have now come to the conclusion that I have to restore it and start again. When I connected the Ipod to the computer and when to iTunes it say it has detected an Ipod in recovery mode. I did the restore and the Ipod shows the Apple logo with the status bar at 0%. I have googled and tried downloading firmware but that has not worked. Any help would be great.
