    I jailbroke on 4.0 with sn0wbreeze, and at first i thought all the stuff in cydia would work on 4.0 (Silly me

    ) So i decided i wanted to downgrade back to 3.1.2. Now since i am on a custon IPSW file, does this mean i have to downgrade to 4.0, then to 3.1.2? Or can i just go straight from a custom IPSW file straight to 3.1.2?

    iPod touch 8gb 2g MC model (Just a heads up)
    Thank you in advanced

    Before when i accidently updated from 3.1.3 jailbroken with spirit, to 4.0, i had no idea what to do.. But then i read somewhere that you can just go back to 3.1.2 whenever you want. I don't think i have the blobs saved unless they're on saurik's server?
    But my question is, could i just downgrade right away or would i need to go to a clean 4.0 first?

    if you have an MC model, then you can downgrade without blobs

    Blobs are handy, but I think you should be fine with going straight from custom 4.0

    Straight from custom to 3.1.2 will work fine. Just DFU Restore.

    You're going to have to use iRecovery to boot out of Recovery Mode once the Restore finishes.

    I think blackra1n does too, doesn't it? Not sure about that, though.
