ipod touch does not recognize the charger (or any charger)

Try the not charging topic of:

iPod touch: Hardware troubleshooting

Also try another cable and look at the dock connector on the iPod. Look for abnormalities like foreign material, bent or corroded contacts and cracked or broken plastic pieces.

Put your iPod Touch in DFU mode, restore and update it with iTunes.

Here's how:

• Connect the iPhone to your computer and launch iTunes
• Turn the iPhone off (hold down the power button at the top of the iPhone)
• Hold down the sleep/power button and home button together for exactly 10 seconds, then release the power button
• Continue to hold down the Home button until a message appears in iTunes telling you an iPhone in recover mode has been detected

• When you are in DFU mode your iPhone screen will be completely black
