Then the connections on the phone may be causing the problem. did the phone get wet or was it exposed to moisture? If you are able to, look at the connectors and see if they look discolored or not clean. you can try cleaning them but be very careful. if that does not work it may be a hardware issue and the internals may be showing to the OS a problem that does not exist or one that is not visible to you.

You already tried the reload so if none of this works it may be truly hardware and either repair of replacement would be appropriate depending on cost.
