I have the e800 propulsion system installed with an A2 flight controller. I updated the firware via the esc assistant and everything works fine, but when I unplug the battery and plug it back in the esc's no longer recognize the motors. I can update the firmware again and it works again, but then the same things happens everytime I turn the power off and back on.
The other odd thing is that when I am updating the firmware on the esc it says I am upgrading from version 1.02 to 1.02, which leads me to believe that the esc has the correct firmware already and its another problem. Does anyone have any suggestions on how to mitigate this problem?

Hey, I have problems that one of my ESC 620S doesn't detect the motor, the DJI ESC assistant says "motor is not connected" though is already connected, I already replacing the motor and still "motor is not connected". Anyone know how to solve this?
