    Helloooo !

    I am desesperate... Yesterday, I tried to update my ipad2. It was on IOS 6.0.1 (I think), to move to Ios 7, to update the apps.
    So, when I start the update, it rebooted, then shows the apple, then the itunes logo with the usb cable.

    I started iTunes, connect the ipad, and click on restore. and I got this error :
    The ipad can't be restored ; unknown error (21).

    and if I click on "shift+restore", in order to choose an image ; I do have "the ipad" can not be restored, unknown error (3194)"...

    I got the .shsh copy from cydia. So... what shall I do ? I cannot use anymore my iPad, and I am pretty sure it is not a hardware problem...

    please heeeelp

    Kind regards
    Miss K

    hello,
    thank you very much for your help
    So, I read your tuto, and by following it ;
    I succeed to reach the Dfu mode (itunes told me that he detected an ipad in recovery mode)
    Then I download the ios 704 (to have the latest version...)
    my ipad is an ipad2A1395, it was jailbroken with 6.0.1 (I think)
    so I choose =>
    WiFi Only

    7.0.4 - http : //appldnld.apple.com/iOS7/031-1...a_Restore.ipsw
    (should I used WiFi Only - Hardware Revision A ?)

    Then during the restoration, iTunes said : the ipad cannot be restored ; unknown error 4014

    glups ?

    This error means that there's a problem with the USB connection.

    Try using another USB cable; a different USB port; add or remove a USB hub between iPad and computer.

    thank you. I am a bit surprised by the cable problem. I will go the apple shop this afternoon, with the ipad to see if they can do something for me, and maybe to buy this cable... I keep you up to date !

    Honestly? No, not really. Apple has changed the verification process so much that saving SHSH blobs from iOS 6 on is more of a habit than anything. Maybe a bit of a hope, too - in that someone might one day figure out how to use them again. But, they haven't, yet. :)

    Still, I save mine (using Tiny Umbrella, which is updated to save iOS 7.0.4 blobs). They take up little space and it's an easy process... So, I save as this action fits neatly into the "well, you never know" category... :)

    Oh, and the only ones you can save are for iOS 7.0.4 as that's the most current one being signed by Apple.
