    Being unable to enter DFU mode is more likely that either your home or power buttons are broken (hardware). Or that you have the timing wrong

    thanks. i did get to dfu. but now i'm stuck on waiting to reboot. any suggestions?

    also how can i upgrade to 3.x without going to 4.x? I've downloaded 3.1.3 but don't know how actually upgrade. would this allow me to use jailbreakme?

    Thanks

    Unplug then replug the USB, that generally fixes waiting for reboot. Otherwise try a different computer or USB port.

    There is nothing stopping you from upgrading to 3.1.3 (Apple does not restrict the 3G from loading any iOS 3.x.x version like it does with the 3GS and newer).

    If you want to prevent your baseband from being updated, then you need to use pwned/custom IPSW iClarified - iPhone - How to Jailbreak Your iPhone 3G on OS 3.1.3 Using PwnageTool (Mac) or the Preventing baseband update as a last-ditch effort [iPhone Dev Team] technique.

    There are two good reasons for preventing baseband upgrade:

    1. retain ability to unlock
    2. retain ability to downgrade back to 3.0
    3. risk that baseband upgrade fails - phone bricked


    negatives of preventing baseband upgrades
    1. newer basebands may have better network performance
    2. newer basebands may have better battery life
