When I've recently gone to charge my Sony Ericsson C905, a message has come up saying "battery cannot be charged. You must use a Sony Ericsson battery". The battery is a genuine SE battery so I bought a new genuine SE battery to try in the first instance but still got the same message! I believe that the charger port or block is possibly faulty and can be replaced but I have no idea how to get the part out of the phone! Please does anyone know how to do this and what "tool" I may need? Thanks
