Using a 5D mkII with 2.0.4 Firmware and 0.1.8 Magic Lantern
I have Hawk Woods external V-Lok batteries going into the 5D mkII via a Hawk Woods dummy battery.
When turning the camera on the camera screen says that the camera cannot communicate with battery and asks whether to use it anyway. I (obviously) select 'Yes' and then initialise Magic Lantern.
The normal ML display appears BUT the camera will not enter into the record mode when the 'SET' button is pressed. ML instead crashes.
