Definitely worth a try. You will lose all your data on the device when you restore via Sony PC Companion. Make sure you get the model number correct. There is usually a white tab on the side that you can pull out of one of the card compartments that has the model number on it. Otherwise the model number may be on the back or bottom of the phone instead.
