After a crash, the drone does not detect its gps / IMU module. There is no apparent damage on the drone, but it can’t detect gps anymore, the gimbal doesn’t move, and the IMU reports an error. With that, the drone motors won’t start. Everything else works. Still can take pictures, make films, etc. Could a gps/IMU module have been broken at impact, but not no physical damage in the outer shell?
Yes. It could be as simple as a connector becoming loose or a quick calibration. There was some laptop software that would do a complete calibration. You could get it from DJI website. I have had to replace broken components but first I would do a gps and IMU calibration.
If calibrating the drone does not restore the GPS, try replacing the module. I made a detailed video tutorial here DJI Mini 3 Pro GPS Module Replacement
Man I have the same issue, but I open the Drone and discovery the flat cable of gps are broken. Just buy one in alyexpress and be happy. In YouTube have a video whit disassemble mini 3.
