Ok need some help here. Looks like my new Inspire 1 is a lemon. Came to me with a bad TB47 and the USB on the transmitter does not work, so no DJI Go access. Here is my dilemma, this morning before I knew of the USB issue, I upgraded the firmware on the AC. Now the transmitter won't upgrade to the new firmware because of the USB issue and I'm stuck with the AC in the legs down position instead of travel mode. I think the only way I'm going to get that fixed so I can send the unit back is if I can downgrade the ac firmware to match. Does anyone know what the last Inspire 1 non v2.0 used for firmware? Also does anyone know of where I can find FW outside of v1.3, 1.810 or v1.910?
