    I have a iphone 3g without a sim card that I'm trying to jailbreak so that i can use without sim card.

    I can't seem to get it into DFU mode trying dozens of times. (I've had no problem on any other phone) so I wanted to use DFU-IPSW. I made the IPSW with redsn0w, but don't know how to proceed from there.

    When I select IPSW it says it is not supported by this version of redsn0w.

    any advice?

    With the DFU-IPSW SHIFT-restore(win) or ALT-restore(MAC) in itunes at the end of the restore the phone should go into DFU.

    form the Dev-Team:
    "In redsn0w, go to “Extras->Even More>DFU IPSW” and select an IPSW that is currently being signed for your device and that you’d normally be able to restore to without any hacks. redsn0w will create an “ENTER_DFU_” version of the IPSW that you can restore to just like any other IPSW, except that now you’ll be dumped into DFU mode towards the end of the restore (WARNING, your screen will remain completely black…the only way to even know its on is that iTunes and redsn0w will detect it!). The technique used by this feature is 3 years old but surprisingly still works today!"
