the only thing was It had a prompt that you had to agree on..saying you was responsible for your settings, not dpi.lol but iam telling my experience,,,taught and make jokes but that what mine did..

I did the upgrade also and it set everything back to default,,well after that I wentback and set mine back to my settings and they worked but one thing was my iPad video coming back was delaying or jerky almost freezing up for a few seconds, so I like the older FW.
Dont worry about that,,,ive had mine miles away and at times lost signal and it came home, I did it just to see if they wouldwork and they all did..,I have other dji quads and all return,,,when comming home you will regain signal...I love all them
