the phone is in a restore mode noe but i am trying to get it into dfu mode... i try to hold both the home and the power and it shuts off, then comes on and then cuts right back off after 3 sec if i still hold the buttons... i tried even swaping parts with a working iphone (that has no sound now see other post) since the home button worked on that phone and still couldnt get it to respond... would that mean that there is a problem with the board itself? any suggestions would be great thanks
