Ok, so I am completely new at this business. A friend of mine purchased a verizon droid 2 global and was attempting to make it work with at&t. I have no clue what he has done to it but it will not even turn on. He said if I can fix it I can have it. When I plug it in to charge a little white light comes on by the port but no screen or back lighting on the keyboard does. I plugged it into my computer and the computer doesn't even show it as being plugged in. Any help would be appreciated.
