So today i bought an iphone 3G for super cheap. The guy said it had turned on earlier but at the time it would give a white screen and flash if you pushed the lock button or pressed on the screen. I took it home and put it in recovery mode and then my computer recognized it but then i tried to restore it and it game me the error 23 (The iPhone could not be restored unknown error) I tried DFU mode..... same thing. The iPhone wont turn on normally but it will go into DFU and recovery mode and show the apple logo and the connect to itunes picture but it appears as if the backlight is broken because it is very dim. So i am just wondering what needs to be done to repair it. Is it a LCD issue or a battery problem? All help is appreciated, Thanks.
