    I have a 4s that won't boot.
    It will show the apple logo but then the apple logo dims for a second then turns off.
    ITunes will recognise then phone but when I try to restore it will die just after the loading circle. Right before the progress bar is supposed to appear.

    I can force the phone out of recovery mode but it just starts the boot crash loop

    Has anyone got any ideas how to sort this?

    I can get into dfu mode but nothing changes.
