Restore iPod errors to Sad iPod icon and sometimes plug into wall.

@alienozi The older iPods required that they be disconnected from the USB port and plugged into an external power adapter i.e. wall charger. Once plugged into that it would perform the final step of the either restore or update.  You must use a firewire AC adapter to finalize the restore process. A USB AC adapter will not work. It syncs, but does not finish it's restore process without Firewire. While the iPod does technically charge over FireWire, the port that you're using has to be able to supply the necessary voltage. Some FireWire ports, as well as USB ports, particularly those found on laptops, don't necessarily supply a charging current, and therefore the iPod won't charge from such a port. The port needs to be powered in order for the iPod to charge from the USB port.  Your Android or any other USB charger will not work.
