HELP!!! I have tried to restore my iPad from the Settings but it stucked in an endless rebooting process (loading over and over). First trial, i got the message error 3194 which I resolved with TinyUmbrella (TU) Second trial, i got the message error 21 which I could solve by putting the iPad in Pwned DFU Mode (or Safe DFU Mode): Third trial, i finally got the message error 1600; I could not do anything to it. I have checked whether I was really in Pwned DFU mode (Redsnow and iREB confirmed it) or whether my firewall and antivirus were desactivated or whether I should customize my IPSW file with Redsnow; but there is nothing to it, I'm still stuck with the error 1600. Any idea please?
