I am getting really frustrated and was just reminded of why I would never jailbreak again. All I want to do is UNDO this absinthe mess and go back to my stock iPad and cannot. It is very frustrating and I would be very grateful if someone could help. I have the new iPad. Downloaded the Absinthe untethered and now I have a jailbroken iPad. Great. Cydia is installed. I backed up my iPad right before I did it. It has the latest Apple firmware. Now I want to go back to the way things were yesterday and cannot. If I go into setting and choose erase all contents and settings, it doesn't work. I just get that black screen with the spinning thing for hours. I try to restore in iTunes and all I get is either error 21 or 1600. I have tried recovery mode, DFU mode, etc. NOTHING works. I either get error 21 or 600. So it appears that now I an stuck using it jailbroken. WHY? Thank in advance for any help.
