I recently tried to upgrade my iphone that has been jailbroken and it crashed I then tried to restore it back with itunes but it crashed again. I tried to go into DFU mode and tried to restore through redsnow but it still doesn't work. i tried a different version of redsnow and it shows that my iphone is in WTF mode. Plz help me out with this. what should I exactly do to restore the iphone back to its factory settings..??????????????

BTW i have an iphone 3g
