I am new here so sorry if I ask a trivial question. Actually I am trying to upload the rover 4.0 firmware on the a black Cube and, it connects, erase, then upload the firmware. But what happen is, when I got a panel telling me to click OK when I heard a tune, the cube switch off. Then when I replugged the USB on the computer, the black cube is blinking orange - which is always a bad sign…
Can you tell me how to do from there?
