You're right, it shouldn't be that difficult. I started by attempting to update the firmware by plugging the camera into my Mac and using the desktop software GoPro Quik. After several attempts I always got the same results, would update to 66% and stop. The update screen would disappear and the firmare didn't seem to make it onto the camera.
When attempting to update using the data card it would go through the motions of installation as apparent by the screen on the GoPro but would never complete. Finally it did however after persistance.
