Iphone 3gs apple logo flashing
I have an iphone 3gs that does nothing when not plugged in but when i plug it into the computer and the apple logo will come on and go off. I plug it into the wall charger and it boots up but says the phone needs activated and wont let me do anything else and when i unplug it to plug it into the computer it shuts off. I have put it in dfu mode and it goes to restore but at the end of the process when almost done the phone shuts off. ive looked up every way possible to fix it and have done everything but have had no luck..
