After successfully upgrade of the new controller to my Phantom 2 Vision plus, I ordered one for a friend. Out of the box, all was normal with the green LED lights coming on when powering up. In the middle of the firmware update, suddenly all lights went off and the computer said no device connected. And that was it-nothing. I was able to charge the battery with the USB cable (as the red light turned green) but nothing else. So the battery works, but the controller will not come on. The board may have been fried, but that is only speculation. Any suggestions or explanations and more importantly how to get the controller to work again would be greatly appreciated. Thanks!!
