The problem is more with the hardware of the ipod touch I believe. I tried multiple cables, ports and docks. There is no recognition by the iPod that any cable/dock has been plugged into it. I saw no need to reinstall iTunes, since the iPod doesn't recognize it has been plugged in.
I tried the same cables and docks with another iPod touch 4th gen, and that iPod worked fine in all of them,
Now the battery is dead with no way to recharge the iPod.
- 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.
