Hello and great forum! I have been scanning through a lot of posts and googling the past couple days about the problem I am having with no luck. I am sorry if this has been posted but cannot find it. I received this on Monday the 7th. I got everything charged up and took it up to my property to try out. I could not get this to flash all green on gps mode. I tried a little later with the same results. The land is in the country with no obstructions at all. I even tried at my apartment and the same thing. All I get is the three red and one green flash. Is there something I have to do? I didn't take this apart or anything like that. I called dji support and they just said maybe it was doa and to return it. That may be the case but I was hoping for some troubleshooting first. Thanks for any help.
