Yeah, the hacked 0000 includes a "good" certificate so the goggles won't pester your about the firmware.and goggles with 0015 or 0020 will allow you to take off without drone firmware update? I would call it a clear oversight on DJI part, they released 0020 for the drone to kill certificate hack and once downgrade was possible bumped ARB on 0015 to prevent downgrade yet on goggles that are required to fly the drone they didn't block nothing on 0015 and 0020...??
