    Default iPhone 3G, 3.1.3 to 2.x without SHSH
    Hello guys!!
    Well, i have an iPhone 3G (normal, SIM free) with:
    - iOS 3.1.3 (restore with TinyUmbrella from 4.2.1 to 3.1.3)
    - Bootloader: 5.09 [G2M3S2]
    - Baseband: ICE-05.15.04
    - iPhone SIM-free
    - i do NOT have any SHSH of any firmware

    can i downgrade this phone from 3.1.3 to 2.x (2.0 possible) with DFU (ireb) -> iTunes -> TinyUmbrella ( exit recovery)
    ??
    P.S. I do not have any shsh so could you please help me? Is it possible, also, jailbreak it with ios 2.x firmware ? Thanks

    There were no shsh prior to 3.X firmware. It's possible to get back down to 2.X firmware using an old version of pwnage tool but why would you want to go that far back?

    Because everything in os3 is some kind of slowly... Well i have a lot of problems with pwnage tool because on Windows 7 it come with an error "pwnage tools has stopped to run" with netframework update to 4.5 ..... Other ways to downgrade to ios2?

    You will need a Mac to do it I believe. Not much will work with 2.X, most apps won't even install on it, really isn't worth the trouble. 3.1.3 I would say is the best firmware in terms of speed and compatibility.

    Edit: Did find these if you are dead set on doing it:
