How to recover a jailbroken iphone?

Today, i was jailbreaking my mother's iphone (because i have jailbroken my ipod touch) and it asks me to go into DFU mode. I went into DFU mode ad it started to jailbreak. There was an unknown error saying the phone is missing something. I forgot what was missing. She had an iphone 4, but she also had an iphone 4s. I jailbroke and failed at the iphone 4. She uses the 4s, though. I tried recovering it on itunes but it failed. It said "Unknown Error (21)". Now its stuck in i don't know what the heck it stuck in (DFU? Bricked?) someone please help.

Added (1). Sorry, i meant "How do I recover a DFU/Bricked/Recovery Mode iphone 4?"
Also, i used Redsn0w beta 3.

EDIT: ok never mind, my mother fixed it.

If it was jailbroke before on 5.1.1 its bricked.

Its screwed because you can't send it back and you can't recover it sorrz. *Bricked

  • How to recover pictures from an iPhone? I forgot the password on an old iPhone and don't care if I have to reset it to it's factor settings but there are some pictures on the phone that I really want. Is there a way to bypass the password just to upload the pictures before I reset it? I no longer have the same computer so I can't even connect it to the same iTunes server I had it with before. Hope someone out there knows how to do this.
