If you want to use DJI Goggles 2 with DJI Air Units and Caddx Vistas you have to upgrade the firmware with DJI Assistant 2. But if you previously used WTFOS to get MSP Displayport OSD, you have a problem. DJI Assistant will say “Cannot Load Firmware List. (4-10) Please retry”. It means you have to completely uninstall the WTFOS from the Air Unit or Vista. Plus, do some extra magic to stop the ADB server with wtfos-remove-adb command. This video is a detailed tutorial on how to doit.
Plus, let’s talk about compatibility with DJI FPV Goggles, DJI FPV Goggles V2 and firmware downgrade.
