These errors typically occur when security software interferes with the restore and update process.
FollowTroubleshooting security software issues to resolve this issue.
In rare cases, these errors may be a hardware issue.
If the errors persist on another computer, the device may need service.

Mar 1, 2013 12:20 AM in response to AnaMusicby lesormonde,Hi Anamusic,
Pending the reponses on this question, using a different machine is the next thing I intend to try.
However, I do not have easy access to one and am trying to avoid taking a day off and travelling 50 miles to the Apple store.
Even if I did manage to restore from a different machine, what would that mean in terms of subsequent IOS updates on my MBP?

Mar 1, 2013 12:25 AM in response to lesormondeby AnaMusic,Error 21 can be an indicator that the Device has been Jailbroken... If this is so, then that is the source of your issue....
Unauthorized modification of iOS

If not... then try on another computer and if no joy then it requires a visit to an Apple Store for evaluation.
