can't update my ipod keep getting an error message (4000)

Hi there LucRaynbow,

Thanks for using Apple Support Communities. It sounds like you are getting an error 4000 when trying to update your iPod. Make sure to unlock your iPod before trying to update it using the computer. If the issue continues, try updating wirelessly instead by going to Settings > General > Software Update.
