I have a problem when going to Restore an IOS 5.0.1 on my iPad. Previously I was using IOS iPad 4.2.1 and I have tried to do a restore without creating a Custom IPSW, but in the iTunes window appears Error 3194. Finaly I use iFaith 1.4.2 for Build Custom IPSW, and iReb for make my iPad to DFU Mode. When Restore Software to the iPad on iTunes window appears Error 37. I have to repeat the process several times, but still appear it in iTunes window, and now my iPad didn't work. Please help me about this problem. Thanks!
