Need help. Iphone black screen, can't find solution!
Hi everyone! I have iphone 3gs,but it doesnt work, only black screen and apple logo ( greenpoison logo). I tried to restore firmware to version 4.2.1 with Itunes, but it didint work out error apears (3194). Then I tried jailbreak it with redsn0w and it also didnt work out cuz the same black screen appears. Finally. i tried to jailbreak it with greenp0ison and nothing changed. Anyone can help? Any suggestions ?
P.S. I took iphone from repair yesterday, but there was no Wi-Fi, so i did system restore in the iphone and then all the problems started. I think mender had jailbreaked it with greenpoison. (because of reboot logo).
