Here's a cut and paste of the relevant instructions from the iTunes: Specific update-and-restore error messages and advanced troubleshooting document.
Rename, move, or delete the iOS software file (.ipsw)
iTunes uses "ipsw" files to restore your iPod or iPhone. If those files are unusable, then try deleting them, renaming them, or moving the file to a different directory. This will cause iTunes to download a new copy of the IPSW. When a restore issue is specific to a user, it is likely due to an unusable .ipsw file. If removing the .ipsw file does not resolve a user-specific restore issue, then the issue is caused by other user-specific security software settings or iTunes preferences. Creating a new user will also cause new .ipsw restore files to be downloaded in the new user. You can find the ".ipsw" files in these locations:
