I'm concerned about upgrading firmware since I understand that one must log into the DJI website before each flight since the firmware version 0800 has come out. Many times, I'm flying in areas that are "dead zones" and there's no connection to the internet. My second Mavic Pro, I just received from DJI has that version on it.
My first Mavic Pro, now about a year old, has never been updated and flies perfectly and always has. Never crashed either or even come close to having a crash. I never have my Nvidia Shield IPad connected to the world wide web during any and all flights.
I used a friend's new IPhone 8 to activate the second Mavic Pro on DJI's website (my account), since I was in fear of the activation process affecting my Android, Nivida Shield that I have been using on my first Mavic Pro AC and RC controller.
Anyway I can get rid of the .0800 firmware in the 2nd Mavic Pro AC and get it down to a firmware version like .0400 or lower ?
