iPod touch: Hardware troubleshooting
- Try another cable. Some 5G iPods were shipped with Lightning cable that were either initially defective or failed after short use.
- Try another charging source
- Inspect the dock connector on the iPod for bent or missing contacts, foreign material, corroded contacts, broken, missing or cracked plastic.
- Make an appointment at the Genius Bar of an Apple store. I suspect a hardware problem due to the hotness. If iTunes can't see the iPod then uor only hope if to contact a data recovery company for getting data off the iPod. If you have an iPod backup you can restore another iPod, iPhone or iPad from the backup to get the data that was in the backup
