Currently setting up a new Phantom 3 advanced. Updating to firmware 1.2.8 The Drone updates fine. The RC does not update. The current RC version is 1.1.5. The DJI online technical support is telling me that the 1.2.8 firmware does not update the RC and that the RC running 1.1.5 is fine. It sounds like they are just trying to push this issue aside. Is the 1.1.5 version correct and updated? Tried multiple card readers, multiple usb sticks, the gimbal method with no result.
