First the basics, I have an ipad 2 32gb never been jail broken. Two days ago I was using my ipad with no problems. I sat it down for a few minutes and when I came back to using my Ipad, it was in recovery mode. When I go to plug it in to restore it I get an Error 21. I've looked for fix's but they all Involve the ipad being jailbroke, which mine is not. How can I get it out of recovery mode? I tried putting it into DFU mode and then restoring and no luck. I've heard about TinyUmbrella but not sure how it would work with an in-jail broken Ipad. There has to be a way to fix this. Any help would be great. Thanks.
