My DJI Phantom Advanced took a tumble during landing. My propeller caught the pavement and flipped the drone over on its back. Propellers still going full speed I managed to pickup drone and turn off. Tops of propellers grey/black color is rubbed off a little. No physical damage to props or body of drone. Now done will not fly, error compass needs calibration. When attempt to calibrate compass I receive error "To Strong Magnetic Interference Detected. Ensure that there are no magnets or metal objects nearby and hold the aircraft at least one meter off the ground when calibrating." Attempted several attempts to hold drone away from me in an open field and slowly turn clockwise, no luck. It passes horizontal then goes to vertical test.... then gives failed message. Also, something new... during calibration I hear a female voice say P-ADDI mode several times. She was quiet before. I have tried to degauss the compass on the back right leg of drone using a magnet. Also calibrated IMU. Both have had no effect. I believe the compass is working because I am getting a reading on the MOD value of 1700-2200. When I attempt to fly I get "Compass noise too high, Contact DJI customer support if problem persists after restart" I am confused. Any help would be much appreciated. My little done will not fly. Internal sensor damaged? PCB Board? Not sure... Please see screen shots.
