    Today my iPod randomly shut off and the screen wont turn on. When I plug it in my computer makes the noise and when I put in in DFU etc. it makes the noise as well. When I try to restore using iTunes, I get error 3791 and when I try restoring using a .ipsw I get error 21. I've searched up some other posts put none of their solutions seem to work.

    My iPod is jailbroken with GreenPoison and I am willing to wipe everything from it to get it to work again.

    Can anyone help me out?

    Please dont tell me to just hold the power and home button, Ive tried that many times

    Attempt a restore with recovery mode instead of DFU and see if that will work. Be sure to try restoring to a stock firmware. If that doesn't work, then try a custom firmware.

    Edit: Custom fw only works if you have SHSHs saved, if you don't well then you'd have to use stock since I don't believe iOS 6 can be made into a cFW yet.

    I think the issue is that I am stuck in recovery mode. As soon as I plug my ipod into the computer, iTunes says it is in recovery mode and needs to be restored. When I try to restore is gives me error 3791. I've tried the regular update and also 5.0.1, 5.1.1. 6.0 gives me error 21.

    And yes I have removed all apple associated things from my hosts file.

    I have also tried iREB but as soon as it counts down, it finishes and says my ipod is in DFU state but nothing on the iPod changes

    iTunes will say it is in recovery whether you are in dfu or recovery. If you do not have the iTunes+USB screen, you are not in recovery but are in DFU.

    Do I have to shut my ipod off to enter recovery mode? I cant tell if my touch screen is responsive because the screen is off, not even just black. This makes it hard to tell if my iPod is actually shutting off

    EDIT:Since I couldnt seem to get recovery mode to work, I put my iPod id DFU and clicked "Fix Recovery" in Tiny Umbrella. A Recovery device popped up on the side and now my iPod has a white screen. Not sure what to do from here

    EDIT2: It now went to a black screen and loaded the GreenPoison Boot screen I think.(black screen with white text) It is now stopped at the bottom of this screen

    Is the screen on though? If it is, you can do recovery mode as long as it is ON.

    Only sort of. The only time the screen turns on if it is the white screen or the black one with text. As soon as i try to enter recovery the screen turns off

    What is the sequence you are using to try to enter Recovery mode.

    You don't power it off for recovery mode. While the phone is on, hold home and power simultaneously. The phone's screen will go blank, at that time release the power button and hold home until you get the itunes+usb screen. Keep the phone plugged into the computer during the entire process.

    Ok, if you keep trying and it still won't go, are you able to attempt a restore with iTunes regardless? If so, try again and give me the error number so we can see what the current state of it is right now.

    Edit: Just saw your update, do you still get the same error number by clicking "restore" rather than "update?"

    I don't think I've heard of a 3794 either, are you sure that's the correct error number?

    Ok. Have you ever edited your host files before, or used TinyUmbrella on the machine you are using to restore?

    If you have TinyUmbrella and the option is checkmarked under Advanced, uncheck point to Cydia on exit.

    Also, have you attempted a shift+restore to stock iOS 6 yet?

    I've unchecked it. I just tried to restore to iOS 6 and I receive the same error (3194).

    Just to clarify, should I have #74.208.10.249 gs.apple.com in my hosts file or not?

    That should be correct. I can't imagine why you're receiving 3194 while restoring to a fw Apple is signing, as well as having returned your host files back to normal. Is there another machine that you can try on?

    I'll go try on another machine right now. The .ipsw file i used to shift+restore was the 6.0 from Download iPod Touch Firmware / IPSW Files . That would be the correct one to use, right?

    Yes. It wouldn't hurt to grab the ipsw from here on MMi in the Downloads section, as I know all of our ipsw's work well. But I don't think there's a problem with your ipsw considering you're yielding a non-related error. Up to you.
