Hello i'm new here anyway. I got a replacement Ipad from apple store, When i got home i tried to update to IOS 5.0 from 4.3.5 until the error message came up (3194). I Google it and tried 2 method: 1. Go to c:\windows\system32\drivers\etc\hosts, Edit it and add #18.104.22.168 gs.apple.com Then go DFU mode and recovery pointing to my firmware 2. get "tiny umbrella", Uncheck "set host to cydia" but grayed out Start TSS server, enter recovery mode, go to itunes and recovery pointing to my firmware. Note: I also tried to pointing it to my current ipad firmware 4.3.5 More information of my ipad 1: 16GB (Obviously not helpful maybe) 4.3.5 Jailbroken (tethered) IOS 4.3.5 I got the latest version of Itunes, tiny umbrella & windows is fully updated.
