I am a landlord as well as a Mavic 2 pro owner. A renter that has come upon hard times has offered me his mavic 2 pro. Sounds good right, NO! When it is turned on, only the fan starts up. No gimbal action, no lights, no prop start up. I did update firmware. I get an ESC error, with the usual restart the call DJI. No other error code. Any suggestions? the craft does not appear to be damaged in the least. any thought on what it will take to get this to fly?? I would like to help this renter out, but I don't need an expensive paper weight. Thanks in advance
