I'm at the breaking point. I've been trying to restore my iPad 2 firmware all day today, and have had no such luck. Between trying 2 seperate firmware versions, 3 computers, and many a trial and error, I have absolutely nothing to show for it. My iPad 2 wifi only is currently at ios 5.1.1, and I am trying to restore to the same version. I also have shsh saved for 4.3.5, and would be willing to downgrade if it'll just work. The reson I want to restore is that the iPad has become super laggy and slow, apps keep crashing and some don't even open, and I just want to start it fresh. The problem I'm having is I keep getting various error codes while I try to restore. So far today I've gotten errors 21, 1600, 1601, and 3194, and it just seems like each solution to each specific error code causes one of the others to start again. I could use any and all help, whether through a teamviewer session or Skype, just anything would help. Thanks again.
