HELP!! I just found out this morning that the new firmware is available to support DNG RAW. I watched the video and followed all the steps shown. After inserting the SD card and turning on the phantom, the camera light flashed as shown. I then turned the phantom off and on again, but the camera is dead! No light on the back of the camera. When I connect to the DjI vision app, I get the message 'connect to phantom 2 vision failed'. Anyone else experienced this? Can i downgrade the firmware and start again? My fear is that it won't respond to any further firmware versions.
