Make sure you have the Current Version of iTunes Installed on your computer

You may need to try this More than Once... Be sure to Follow ALL the Steps...

Take your time... Pay particular attention to Steps 3 and 4.

After you have Recovered your Device...

Re-Sync your Content or Restore from the most recent Backup...
