I also can not calibrate the gimbal. I'm doing the activities mentioned or first rc vision assistant and later assistant and plug the Phantom and gimbal runs until the cable connection. How to remove the cable and restart the gimbal do not work. From purchase gimbal I worked two days and stopped working. Sometimes the fifth turning gimbal later works and does not work again. What to do ??
And here's a video of the calibration
In your calibration I did not see you first make sure the new controller box is checked? There is a selection between the old style controller and the new one.
