hi guys i have an Iphone 3GS and i cant get it to work anymore. before things went wrong i had my iphone (not jailbroken) plugged into my iphone speaker set and suddenly it rebooted and went to restore mode. First thing i did was connect it to itunes and try to restore it. however, itunes failed to restore it due to a unknown error. Im not able to turn it off but i am able to put it in DFU mode. so i tried to jailbreak it with redsn0w_win_0.9.10b4 and first it looked like it was succesfull. it started up like it used to and got the configuration wizard. but after a certain amount of time it automatically rebooted and brought me back at the configuration again. ive send it to the repair fabric but they said they couldnt do anything and they send it back. i think they didnt do **** so im asking you guys if you have any idea to fix this. thank you for your attention and i hope you can help me!
