I have an original C2 from Kickstarter which has not been updated to the latest firmware and is showing A 1.3.2, B 1.3.1, C 1.2.5, this unit is working fine with my Canon 7D.
The unit I received yesterday, was updated from Firmware 1.0.0 upon arrival to the latest A 1.3.2, B 1.3.1, C 1.3.0. This version does take power from the camera but does not communicate with it and is therefore unable to do anything. There is no error message, but I am informed that the USB on my camera is not active (the 7D does not have wifi and the USB is not disabled, I can control it perfectly with my original Kickstarter C2 and via cable with my PC).
Is it possible to roll back the firmware? Is anybody else having this same issue?
