Is their any possible ways of undoing a update. I recently just updated my ITouch to 4.3.3 but it stopped me from using the Jailbreak apps. it tried to jailbreak it again with snowbreeze but don't know why a error occurred while restoring and won't let me restore it. i'm thinking now is their anyway to undo the update.
you have several options as listed by the other posters..
A. you can go back to a previous iOS version if you have SHSH saved, use Tiny Umbrella to check.
B. there really isn't a reason to revert to older iOS as 4.3.3 can be jailbroken with redsnow 9.6rc17
C. so you can restore using Apple ipsw 4.3.3 and then jb with rs 9.6rc17 or..
D. you can custom restore by creating an already jailbroken 4.3.3 ipsw using snowbreeze 2.7.3
hope this helps explain the answers the other posters have already generously provided.

If you're talking about undoing an update, i.e. going back to the firmware version pre update, then yes it can be done.....but, you need to have shsh's for the downgrade
