We Found the Hidden Menu of DJI FPV Goggles! DJI Digital FPV System firmware has been released, what impressed me most about the new firmware is the 50Mbps bitrate mode. But note that it is only available in FCC areas.
The Air Unit has been unlocked before, but it needs to be unlocked again after updating the firmware. The unlocking method is simple. Create a new TXT file and name it "naco.txt". Then directly type a number "1" in the file and save it. Copy and paste this file to the SD card, and insert the SD card into the Air Unit. Now is the time to witness the miracle!
There are only three channels in the 50Mbps bitrate mode.
In 25Mbps bitrate mode, there are eight channels.
Then create a new "TXT" file, name it "naco_pwr.txt" and type "pwr_2" in the file and save it. Copy and paste the file to the SD card and insert the SD card into the Goggles. Now the hidden menu will be shown. A channel is added in 50Mbps bitrate mode and the max power now can be set to 1000 mW or 1200 mW. (If the Goggles have been unlocked before, unlocking is not required.)
