Edit: Fixed! The motor-ESC connection needs to be strong. To get solder to stick when splicing wires, sand the coating off the wires and then tin, otherwise it won't stick. Will the motors start if one motor is disconnected? My story: I attempted to take off on a windy day at the beach and my drone tipped backwards and two motors froze up with sand, so I turned the unit off. Unable to disassemble the frozen motors I ordered two new motors. Those came in today. Because of the silicone used at the factory near the solder joints, I decided to cut the wires and splice/solder them further up the wire. I was surprised to see that DJI only uses two strands of wire. I attempted to tin them using flux and solder and the solder just wouldn't stick. Plan B was to splice the wires by hand and use heat-shrink tubing to protect and hold them in place. After completing the first motor, I attempted to start the motors and got the "ESC status error". I updated the firmware and re-calibrated to no avail. I read that this error can have many causes, one of which is a lack of communication between the ESC and motor. I disconnected the new motor and attempted to start (three motors connected) and got the same error.
