I too had a dead h3-3d (does nothing when I power up the phantom, no self test, nothing) it was getting power because its light was green. I was able to short out the 2 points on the gimbal. Then I could only update the firmware using Phantom Assistant V3.0 (wouldnt work on V3.2). With that said I was successful in updating the firmware of the gimbal but it still wont do ANYTHING when I power up the Phantom and now there is a red light on the gimbal. Has anyone else experienced the same issues as me and gotten the gimbal to work? If so how?
