What doe's it mean? How can I upgrade the camera of my Phantom 3 Professional? When I switch on my Phantom3 Pro the camera make a "crazy" ballet. I've inserted a micro SD with the last firmware, but the front led becomes green and red without stopping and without sounds. Finally it blinks green and again red and green, not a solid green. I specify that the DJI GO app says "Camera requires Upgrade" after a substitution of gimbal with another repaired P3P gimbal. Is there anyone who can help me?
