    Default iiPhone stuck at Recovery mode, 3194 error when trying to restore

    I might just butt in here as I'm getting the 3194 error Olethros. Sorry I know there have been postings about it but I am trying to figure out whether I can get iPhone to work again at the moment without waiting for new jailbreak. I believe it is stuck in DFU mode, iPhone has black screen and is recognised by itunes.
    Originally I tried to jailbreak using pwnage tool 3.1.4 in December, which was stupid I gather after some research for myself. I have tried to restore to 3.1.2, 3.1.3 & 4.0 all with various errors on both OS X, Windows 7 32-bit and XP, and on various itunes versions also.
    Most recent error is 3194 which I understand means apple aren't signing firmware version anymore (4.0 update attempt), I am getting this with itunes iPhone 3GS 16GB, iBoot -359.3.2. I don't have any SHSH's saved as iPhone was never jailbroken.
    Only way to get iphone to come back to life to restore to 4.2.1 and have it locked to original carrier or is there a way to force iPhone into restore mode?

    You've threadjacked a somewhat unrelated thread. Also, your specific problem has been asked and answered quite a few times here on the forum.
    So i've moved you to a separate thread.

    OK, you've done a lot of stupid things, lets start!
    iBoot -359.3.2 = new bootrom 3GS, meaning you have to be very careful with pwnagetool custom IPSW (they generally don't work. The exception being iOS 4.1 - with a 4.1 SHSH)

    By restoring with a custom 3.1.3 or 3.1.2 IPSW made with pwnagetool 3.1.4 you have probably corrupted your LLB and which leaves the device in DFU mode because the LLB is the first piece of software that the bootrom tries to load.

    There are no known exploits or ways to get around the SHSH requirement on a new bootrom 3GS (or any iOS device newer than this). You absolutely need a valid, SHSH for the OS you are trying to restore, even if you are restoring custom IPSW.

    It is an incorrect assumption to make that because the device was never jailbroken you have no SHSH saved.
    The only way to be sure that there are no SHSH on file for this device is to get the ECID (which you can find when the device is in DFU mode) and click the "manual ECID" button in TinyUmbrella, this allows you to manually enter the details for your device and then it will appear in the left sidebar. You can then highlight your manually created device and click "Save SHSH" this will give you a definitive answer on whether you have any saved SHSH or not.

    Now where we go from here, depends very much on what you find out from TinyUmbrella. If you discover that you indeed have no SHSH saved. Then 4.2.1 is your only solution (as Apple is not signing anything earlier)

    Okay, restoring iOS 4.2.1 requires iTunes 10.1 as a minimum.

    If you have saved SHSH, then you have more options, depending on what SHSH you have saved.
