I have a Mavic Pro platinum that crashed and I am working on repairing it. It appeared that it was mostly body damage and I was able to replace the casing and the landing gears. When i insert and turn on the battery, everything turns on and the lights, camera and propeller motors all engage. Unfortunately, it won't connect to the RC or make a wifi signal. The linking status indicator light does not turn on and it won't connect to Assistant 2 on Mac or PC. Any recommendations?
