Are you checking hold switch and doing steps below 1. Toggle the Hold switch on and off. (Slide it to Hold, then turn it off again.) 2. Now press and hold the Menu and Select buttons until the Apple logo appears, which may take about 6 to 10 seconds. You may need to repeat this step''. I think this is the best way before taken it to Apple store or centre.
