i tried restoring it due certain lagging issues. and what do u know i get the 1604 method. i googled halfwawy across the world and tried almost everything(reinstall itunes, restore on different computer) but to no avail. then i stumbled upon DFU. i tried it, and now it gives me a 2001 error. is my ipod stuck like this forever? can anyone clarify whether this is a hardware or software issue? and yes, i've exhausted my warranty.
