Trying to upgrade 3G 3.1.3 to 4.0.1...Possible?

[lansa]

So, I have an old 3G (3.1.3) that I just jailbroke with jailbreakme. I then proceeded to install ultrasn0w thru cydia. After rebooting, I try to go into cydia and immediately get kicked out, just crashes back to homescreen. I did save my SHSH before I did the unlock.

My question is, is it possible to restore to 4.01 in iTunes? I tried doing it but kept getting error 3002. I have Tinyumbrella running, but it only shows iphone 3G with 4.xx firmwares. Anyone can help me with what I need to do to restore to 4.01 if possible?

Hashes are needed for 4.x.x firmware but not needed for 3.x.x firmware on 3G
