I've been able to update 2 of my Inspires to 1.2.1 without any issues. However my third one gave me a weird issue. I've linked a youtube video so you can see/hear what's going on. The sounds it made went on for the entire 20 mins it took for the update to complete. I finally heard the D--DD from the camera meaning updated was successful and when I checked the log file it also said "success". As you can hear in the video, the camera is still making the standard DDDD sounds while performing the update. It's the very loud beeping that is coming from the ESCs that I've never hear before. I just wanted to find out if anybody else had this loud beeping from the ESCs when performing the update.
