I have owned my Phantom 4 for a couple of years now. I have upgraded it several times without a problem. Have read a number of posts from guys that have had problems upgrading and couldn't help wondering what they might be doing wrong. Well all of a sudden I am having a problem with the latest upgrade from DJI. I guess it's not "if" it's "when". I use the assistant 2 app as I always do and it gets to about 98% and says the upgrade failed, try again, same thing. Now when the P4 and the remote are on, the light on the remote just flashes red and green. I also tried the DJI app and basically the same thing. I also have the Litchi app but can't get to it because the remote seems to be locked. I have also tried resetting the remote, no joy. I am sure open for suggestions.
