i replaced the 2 pair of propellers which is stored downward inside the MM bag. Saw the youtube video that's the reason why we will get this error cause when we put our mavic mini down into the bag, the propeller will be accidentally pressed down on the hinge of the bag.
Glad it solved your problem and happy flying.
With many "motor error" solved by replacing the propeller. I have been convinced that the propeller of MM is soft & flimsy, extra care is needed.
The reason behind of the motor error is, in 1.00.5 firmware update, DJI added a mechanism to detect unusual motor speed.
An uneven prop could cause the motor to spin to the max thus trigger the error.
Interestingly, you could monitor the motor speed using "CsvVIew" after every flight, which I did it nowaday. You might try swap back the old prop and did a motor test.
