First, I'm already in the US and have that option set. Second, I never said it was "grayed out," I said I was limited to the default channels, that the "hack" or mood or whatever didn't change anything. I tried downloading the rar file again, maybe something happened when I un-compressed it. (I don't see why it needed to be compressed anyway). So I will try it again. Like I said in my first post, when I opened a copy of the config file, it was empty. I went to the same link that was posted earlier. Also, should I take the file out of the folder it comes in before I put it into the "android\data\dji.pilot\files" folder? ( not sure if I wrote the complete path here, but when I transferred it before I had written the path down from the instructions at the link.)
