I have a disabled Ipod touch I can not restore.

I have a 8gb 4th Gen ipod touch. Someone had left it at my church and never came back for it so it is now im my possession. Just one problem, it is disabled permanently and says to connect to Itunes. Well, I put it in recovery mode and tried to restore it that way.. It loaded for 4 hours and then went back to the lock screen like nothing happened. So I updated the ipod and itunes to the latest versions and tried again. Still got nothing. So I tried to put it in dfu mode... and it all seemed like it was working and then when it said it was finished I turned it back on and went right to the lock screen like nothing had happened...

Did I miss somthing? Does anyone have something else I could try? This is driving me crazy. Thank you!!
