    Hey, Im on 3.1.2, or 3.1.3 i don't remember, Im using an iPhone 3GS jail broken with blackra1n. Im trying to use a custom 4.0 FW i made with pwnage tool. Everyone says it'll work once I'm on 3.1.2 or 3.1.3.

    I go to restore on my MAC 10.6 with itunes 9.2 but then I get error 1604. So I cant get it to restore, I'm trying to revert back to a clean 3.1.2 but iTunes says its going to verify the firmware and then says my iPhone isnt eligible for this firmware. how do I fix it or get rid of the 1604 error?

    I think you have the new iBoot so you can't use a 4.0 custom firmware and you have to find your SHSH files before you can downgrade. I don't know where to get them all I know is that they are stored on cydia servers.

    You would have known if you backed up your SHSH's

    If you hit 'Make My Life Easier' on Cydia, it would be backed up

    At this point, I would just go to 4.0, and wait for the jailbreak
