You have to force iPod into Recovery Mode:

1. Turn off iPod

2. Connect USB cable to computer; leave the other end alone

3. Press and hold the Home button down and connect the docking end of cable to iPod

4. Continue holding the Home button until you see the "Connect To iTune" screen

5. Release the Home button

6. Open iTune (make sure you have the newest version of iTune)

7. You should see "iTunes has detected an iPod in recovery mode"

8. Use iTune to restore iPod

Note: You need to be patient and repeat the above many times to recover your iPod

Update Server

Try:

- Powering off and then back on your router.

- iTunes for Windows: iTunes cannot contact the iPhone, iPad, or iPod software update server

- Change the DNS to either Google's or Open DNS servers

Public DNS — Google Developers

OpenDNS IP Addresses

- Try on another computer/network

- Wait if it is an Apple problem
