Hi All, I'm hoping somebody can help, my Swann DVR4-1300 appears to have been bricked during a firmware upgrade, The update appeared to be working, message on screen etc, but then it rebooted and hasnt booted since. I'm hoping that there is a way to debrick these units with a ttl cable or something like that Does anyone have any idea how i can accomplish this? Thanks In Advance
