You can reset your iPod and see if that works or not. Press and hold the Sleep/Wake button and the Home button at the same time for at least ten seconds. iPod will automatically restarts and return to home screen. If it not restarts after holding the button for 10 seconds, hold down the Sleep/Wake button and the Home button until it get turns off and restart itself.
Let me know if that didn't worked...Only click Accept after it worked. Best Regards, Ashik
Note : Put it to DFU Mode while connected to computer and also in DFU Mode your iPod will remain blank. Let me know if that didn't worked. Only click Accept after we solved the problem. Best Regards, Ashik
