I replaced the ribbon cable,the other cable, and the vibration board for the gimble. I did the gimble recalibration with the DJI GO4 App. This fixed the operation of the gimble. Next I did the forward sensor recal with the DJI Assistant2 app done on the laptop. This took care of the forward senor error and allowed the drone to go into GPS mode. The gimble no longer operates after doing the forward vision recalibration. I have attempted gimble rec with the DJI GO4 App again with no success-can't get past 5%.Can the DJI assistant 2 app on laptop be used for gimble calibration? I appreciate any help.
