I've been trying to update the firmware on my Typhoon H and not having much luck. I downloaded the firmware up date from the Yuneec web site onto a micro SD card, stick it in the camera and follow the instructions on You tube. I get a message that says no firmware on SD card, no update. Tried 2 SD cards, same thing. I tried unzipping the Zip file and same message. Wonder whats going on? Should I update the controller first? If I do and the update still doesn't go into the H, am I screwed?
