iOS 4.0 to Pwned 4.0

[csjo00]

Long story short, I decided to "live on the edge" and try to jailbreak 4.1 with the an unofficial Pwnagetool and it didn't work.

So I successfully downgraded from 4.1 to 4.0 and I'd like to get it jailbroken with Pwnagetool. I have a custom 4.0 firmware and everytime I try to restore to the custom firmware I get an error (1604, maybe) and it just throws me out.

If you haven't figured out already, I have a 3GS with old bootrom..

I figure I'm just missing something that is right in front of my face.
So.. Any and all help will be appreciated.

To use pwnagetool = custom firmware, your phone needs to be already pwned = accepts unsigned code. The last JB the pwned a 3GS iPhone was 3.1.2. Thus, you need to downgrade to at least 3.1.2, JB with Redsn0w, and then, you can start to restoring using custom firmwares.

Lovely. I don't have SHSH for 3.1.2. ... I do have it for 3.1.3 .. Looks like I have to go find that Spirit2Pwn deb file..

Edit: Looks like spirit doesn't work with iTunes 10... So I used jailbreakme.. Hopefully when they release the new 4.1 jailbreak it won't be userland and someone releases a patch like Spirit2Pwn

If the 4.1 jailbreak is not userland (i.e., if it uses a bootrom exploit), then it will not be necessary to have a Spirit2Pwn-like patch. Presumably any such jailbreak would patch out the signature check for pwned firmware.
