I have a zenmuse xt 640 30hz being used on an Inspire 1 v2. It was working perfectly for several months then I recieved the update notice a couple months ago. I updated to the most recent firmware and now my TIFF images show up black and the videos recorded play back in an extremely compressed rate ( a 10 minute video will show as a 3 minute video and will play extremely fast and blurry). I have not been able to find the previous version of the firmware and its causing me a lot of problems with my inspections. please help.
