can't upgrade JB ipad2 to 5.0.1: error 21

[leland]

Hi all,

Each time I try to upgrade my JB iPad2 to 5.0.1 I get Error 21 while restoring as part of the upgrade.

Can anyone help?

Thus far I've tried:
-Rebooting/restarting/etc
-Changing TinyUmbrella so that set Cydia hosts on exit is NOT set
-Breaking my junction for the backup

Can anyone help?

Take a look at this sticky: http://www.ipadforums.net/jailbreak...lsafe-method-restore-current-version-ios.html

I've heard it works great in helping people to go to iOS 5.0.1 - even if you're not jail breaking.

So, give it a try?

Tried that and am in DFU mode. But now... "the iPad could not be restored because the firmware file is not compatible"

AAARGH!!!?!?!

How the hell do I upgrade to 5.0.1?

Ok, and now it works... Bizarre. Honestly I don't think I did anything other than plug and unplug the iPad to restart iTunes. God help someone who has to troubleshoot Apple stuff for a living.
