I have apparently tanked my Phantom 3 Professional while attempting to update the firmware. I have tried everything I can think of to no avail and DJI said I would have to send it in for repairs. It still fires up, rotors spin, there is just no signal from the camera to the screen. I tried putting the camera on another bird but it would not connect on that one either. Anyway, with the new Phantom 4 having just been released I am thinking instead of paying for a costly out of warranty repair just trying to sell it for parts. It's only been flow a few times and never crashed. Anyone ever done this with any luck or am I just wasting my time.
