Impossible to Update and Restore iPod 5 touch
I have forgotten the passcode for my iPod touch 5 and it now says 'iPod is disabled'. I have tried to restore it to factory settings but it seems impossible. After I put the device in recovery mode and connect to my PC iTunes says 'iTunes has detected an iPod in recovery mode. You must restore the iPod before it can be used with iTunes'. I click on the Restore button and it says it has to update to ios 6.1.3 before it can restore. It starts downloading the update but before the update finishes downloading (40 mins) the iPod comes out of recovery mode and iTunes says it cannot connect to device as it is locked with a passcode. I then get stuck in an infinite loop. I put the iPod back into recovery mode and goes though the same process but doesn't detect that it already has the download so it downloads it again (40 mins) and so on etc........
What do I do?
