    Hi,
    Yesterday I accidentally dropped my iPhone 4 (only from a couple of feet). After that, I tried turning it on, it did, but stuck in Apple logo mode (looping).

    Now, the iPhone is not responding to anything, I cannot put it in DFU mode. No matter what I do, I can't get the Apple logo to come out! When I connect it to my Mac, I don't get anything on iTunes..

    How can I figure out the problem? I can disassemble it (I have some experience), but how can I figure out where the problem lies? How can I know which hardware parts are causing the problem?

    It is a bit weird :/ I have dropped it a billion times, never the screen got cracked, or got in any issues. Now, a simple drop made a huge problem!
