ESC Status Error means that one of Speed Control chips returns status other than "All OK".
Since you replaced the motor, you probably know which one is it. If you want to be sure, you can get this information from flight recorder log in the aircraft (DAT file). Information there also includes the status code returned. Though I'm not sure if anyone knows which status code means what..
Anyway, possible causes:
- The new motor is damaged
- The new motor is soldered incorrectly
- While soldering the motor, you damaged the ESC electronics
Try checking things with multimeter, check continuity and resistances. If one is out of ordinary, you have the cause.
