    You cannot downgrade an iPad 2. You are stuck on 7.1.1.

    Try to restore.

    You can downgrade an iPad 2, if you have SHSH blobs for for 4.3.X and 5.X.X. But they must be properly signed and it's more difficult for 3G iPads than it is for WiFi only iPads.

    I haven't done this in a while, but do you not still need to run tinyumbrella while you're restoring?

    I don't believe you can? It hasn't been possible from the A5 chip onwards, and the iPad 2 has the A5 chip, same as the 4s, which also can't be downgraded.

    Unless there's something special about the iPad 2?

    If the screen is black and you get a need to restore message in iTunes, then you ARE in DFU mode.

    Not sure why it gets stuck at the waiting for iPad message at the next step. This happens even if you try to restore to 7.1.1?

    No one has found a bootrom exploit for the A5, A6, and A7 chips yet. People have found bootrom exploits for A4 and previous chips.

    A bootrom exploit needs to be discovered in order to install an unsigned iOS version, with shsh blobs.

    The special thing about the iPad 2 is that is had a public release of iOS 4. The thing that makes A5 devices non-downgradable is that Apple changed how the SHSH blobs work starting with iOS 5 so that they can only be used once. If Apple never changed that, you would be able to downgrade A5 devices. A bootrom exploit is not needed to downgrade them or A3/A4 devices. It only helps in getting past Apple's one time only check. There is one small exception to this rule for A5 devices, restoring from an iTunes restored (cannot be factory or OTA) iOS 5.X to a higher or equal version of iOS 5 as long as you have properly signed SHSH blobs with an APT ticket.

    If you are unable to restore to iOS 7.1.1, it is possible that the iPad is having problems.
