Hi can someone please help me. I have a black mp4 player which doesnt turn on (dont know why).Before it used to show a blue screen with a yellow timer icon. I dont know how to open it. I was tried to use the dead player recovery guide but got as far as the Adfu update.inf part. I have been told to try updating my firmware but cant because my pc doesnt recognise my mp4 player. Please help
