Decided to pull out my P3P and dust it off and refresh the firmware as it was out of date by two updates. During the process, I was able to get a positive upgrade and then an abort listing. Next thing I know is that the PHantom is sitting there beeping real loud and constantly. No break in the beeps whatsoever, so I tried about everything I knew like starting over and still the same beeping. I did notice that on the screen of the iPad that the battery cells were all showing a zero balance on each cell but the battery itself was showing 3 plus lights constantly lit up. Any suggestions on a possible cure. Thanks for any help.
