I spent the night upgrading the Phantom with the new board so I can use the H3-2D. After I completed the install of the board, I connected the 8p wire for the gimbal and then mounted it to the bottom of the Phantom. Powered it all on and the gimbal vibrated for 2-3 seconds then stopped. LED on back shows a solid orange. It doesn't work at all. Through the Assistant software, everything is updated and recalibrated and all that jazz. The software is showing that the tilt lever is responding to movement, so that's good. The gimbal just won't move at all. Not even to face the wrong direction like most people talk about. I'm not using the "GCU V1" so I can't hook up the USB cable and do what that other thread says about plugging in and running through the other program (which isn't my issue right now anyway...). Is there something I'm missing? It won't even vibrate any more. Other than the LED, it appears to not work at all. Thanks!
