I would start with
Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased.
If recovery mode does not work try DFU mode.
I got my USB to connect to my laptop, plugged it in then it came up with 'iTunes has dectected iPod in Recovery Mode' Blah blah blah, I tried restoring it, then it came up with this; iPod Software Update Server could not be contacted' I tried my network settings and they were all fine, and my Internet is fine. Please help.
If my parents find out they'll kill me!
