Q: iPod wont restore

what is the error number? its written in brackets. -1 or -51 or 4001 etc..

Get help with iOS update and restore errors - Apple Support

find your error number, and fix that issue. maybe itunes or your computer is out of date.

if you have another computer that you can try, try that one

go through itunes again and try to restore. try another 2 or 3 times. see if you get the same error each time.

is the cable a 3rd party one or a genuine apple usb cable?

perfect, should be less issues!

+check your security software. if you have antivirus or antispyware, try disabling it temporarily for 15 minutes

programs like AVG, Norton, McAfee can cause some issues when attempting to restore.

+restart your computer

+uninstall and reinstall itunes

+check for windows updates - several times (if necessary) until no more are available.
