I got my advanced and was updating the firmware. Light on gimbal was blinking as expected, red and green. Came back maybe 10-15 min later and light was solid green. Figured it was done and turned phantom off. Loaded up txt file and it just said updating... Or something like that. It didn't say success or anything like that. However when I load up the app it lists the firmware as 1.6.4. Did it complete or not?? I did a test with no propellers indoors and it acts like it takes off fine. When I formatted the card again and tried to update again the phantom is just doing the startup sequence lights and gimbal light is solid green.
