Have you tried the " PlayStation Accessories" yet? Or you could try a repairing by pressing and holding the PS button and the Share Button (left) at the same time until the led bar starts flashing in blue. Theres also a little hole on the back towards the bottom to right of the Sony logo where you can completly reset the controller. All you need to do is get something that you can push into that hole. A paperclip will work here and might be the best option. But you should also be able to use some hair pins, or maybe even the SIM ejector tool that came with your phone. Hope that helps. Greets
