Instructions on how to update from the DJIRCFCC guy.
AT YOUR OWN RISK THERE IS A WAY TO UPDATE DJI RC FROM 01.03.0100 TO LATER UPDATES (01.03.0500) AND KEEP THE FCC ACTIVE
UPDATE THE RADIO TO 01.03.0100, INSTALL FCC (MAKE SURE IT WORKED) AND IMMEDIATELY WITHOUT TURNING RADIO OFF USING DJI ASSISTANT UPDATE TO (01.03.0500)
THERE IS A COOLDOWN OF 2 HOURS BETWEEN FCC INSTALLS, TURN RADIO OFF AND YOU WILL BE ABLE TO INSTALL FCC AGAIN ON THE NEW FIRMWARE AFTER THE COOLDOWN
AFTER THIS YOU SHOULD BE ABLE TO UPDATE TO FUTURE UPDATES AND STILL BE ABLE TO APPLY FCC, BUT ALWAYS TRIPLE CHECK THIS PAGE OR SEND A MAIL
BE CAREFUL AS THERE IS NO WAY TO GO BACK IF SOMETHING GOES WRONG AND YOU WILL BE STUCK IN CE
