Hey, yes I know downgrading via iTunes isn't possible as it won't sign older firmwares. I am on 3.1.1 and have the ECID n SHSH backed up locally. Now I want to fresh clean my iPod and restore it to 3.1.1 so need a tutorial for that. I repeat 3.1.1 firmware and mine is a iPod touch 3rd gen. Any good guide/tutorial for the same would do. Thank you.
