Q: my ipod notifications bar came down and wont go up so now i cant do anything

Try:

- Reset the iOS device. Nothing will be lost      

Reset iOS device: Hold down the On/Off button and the Home button at the same time for at

least ten seconds, until the Apple logo appears.

- Restore from backup. See:                                               

Restore your device from an iCloud or iTunes backup - Apple Support

- Restore to factory settings/new iOS device.                       

- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.
