    Well normally you could get out of DFU mode the same way you get in, by holding the power button and home button down until the apple logo shows up. But considering your power button is broken, that won't work..
    Now I'm wondering how did you get into DFU mode in the first place?

    Modern jailbreaks don't even put idevices in dfu, or they do it automatically without user interaction. If something went wrong a device could still end up in dfu mode. OR, there is a way to modify a ipsw file to enter dfu upon restoring it.

    I see. Lol, are you answering my question or the OP's? :confused::p

    Anyway as you said there is a way to modify an Ipsw file to enter DFU, is there a way to do the opposite, modify the file to exit DFU? Probably not, lol, just curious as that could be a solution

    I thought I quoted your question but apparently I clicked the reply button. I used the instructions here to get in DFU mode:

    http://www.iphonehacks.com/2012/07/...n-dfu-mode-with-broken-home-power-button.html

    What redsn0w does is it garbles up a file that isn't checked by iTunes until the after the restore, but that is important enough that iOS doesn't function without it. Your device would normally turn on and iTunes would check that everything is working properly, but iOS is messed up so badly that it can't even get to that stage. When something goes terribly wrong during boot, the device will put itself in DFU mode. At least that is how I understand it.

    Based on that, I don't think there is any way to modify an IPSW file to get a device out of DFU mode, as an unmodified and original version SHOULD automatically put the device out of DFU mode, and any other mods that you can do to the IPSW won't get past iTunes verifying it.

    Download tiny umbrella. It has a feature that can kick your iPod in and out of DFU mode. It worked for me when my iPod had issues with an iTunes restore.

    If it is in DFU mode, you can also just let the battery drain completely and when you recharge it, it should kick back into a regular restart.
