    Hey there, I'm trying to jailbreak an iPhone 3G for a friend of mine.

    He bought it from an auction house for 80$ and the power button is broken.

    When the iPhone powers on, it just says "iPhone Disabled" on the screen.

    I know that I should be able to restore it in iTunes, but it gives me an error that I should unlock the iPhone with a passcode first, but there is no passcode entry.

    I've tried iPhuc, ect. tools to place the iPhone in recovery mode, but the fact is that the iPhone has no data connection with windows while it is locked.

    If I can just restore it to a fresh firmware, I know the steps to put it in DFU for jailbreaking, I just need to put the iPhone into recovery mode and any help would be greatly appreciated.

    DFU mode = recovery mode.

    DFU does not equal recovery mode; they are different.

    To get past the "iPhone disabled" screen you need to put it into DFU (recovery mode will not work for this). The disabled screen is from the iPhone having a passcode lock on it; you will lose all the data on it but DFU and restore to whatever firmware you want; I would suggest 3.0 to preserve the baseband incase you want to unlock the thing.

    DFU=device firmware update, right?

    I'm going to restore it to 3.0 firmware definitely.

    I've taken the iPhone apart and disconnected the battery to force a shut-down.

    I then held the home button while connecting it to iTunes, putting it into restore mode.

    I've created a custom firmware that should force it into dfu mode once restored.

    I'll post progress here!

    Correct - DFU mode bypasses the current OS installed and allows you to upgrade or downgrade your OS (usually).


    You will need to put it into DFU mode to get past the iPhone disabled screen. I am not sure how you plan on doing this with any custom firmware but it may be possible.

    If it doesn't work; you will have to figure out how to get into DFU mode to do the restore.

    Whoa. You guys don't need to panic if it's at "iPhone disabled" ssh in with an ssh over USB tool, delete /var/Keychains/, then reboot.
