Hi there I made this account hoping somebody on this forum will have an answer for me. My ipad 2 (GSM) running on 5.1.1 (Jailbroken), was running fine for a couple of months now. Sadly, my pc crashed and when I hooked up my ipad he needed to "activate" again. This activation however did not work (because of the Jailbreak I think ?) I tried to restore to the original 5.1.1 but that gave me errors. 21 / 3194 / (I fixed these) , then I tried to use tinyUmbrella and the ssh server , then I got error 1600. There is NO way I can restore it to 5.1.1 Anyone got tips ? I tried almost every possible application on the market. It still just starts and asks for activation => apple activation not working, try again... Thank you so much !
