I jailbreaked my iPad 2 earlier, and today I tried to update to the iOS 5.1 from the settings icon on the iPad 2. After doing so, I entered a recovery loop and I cannot get out. I did not have any shsh saved, and I tried to fix recovery using Tiny Umbrella, but it did not work. I currently have my iPad 2 in a dfu mode. Can someone tell me how to remove the jailbreak from the iPad, permanently if possible, and how to fix my iPad 2 to normal? Any help would be appreciated. Thank you very much.
