Jailbreaking voids the Apple warranty and also means that you will not get any support from Apple, including from this Apple forum. Jailbreaking can't be discussed in this Apple forum.
You can try putting the iPod into DFU mode and see if that will let you restore and remove the jailbreak:
Some jailbreaks cannot be removed and in some cases will permanently disable your iPod. If that happens to you, then you will have to buy a new iPod; Apple will provide no support, warranty or out-of-warranty, for a jailbroken device.
You're on your own from here. We can provide no further help with a jailbroken iPod in these forums.
Put your iPod in Recovery Mode and restore the iPod on iTunes. It will reset the iOS firmware.
Settings>>General>>Reset>>Erase All Content & Settings
PLUS if you received any unknown errors on iTunes just give it a few hours or a full day....it means your iPod is trying to repair it self from being JAILBROKEN.
