The P3 firmware update procedure is about the same as the camera update on the P2V.
Actually its almost exactly the very same thing But with out any reports or any one bricking any thing yet whats so ever.
I have had one or more of almost every phantom made so far and for the life of me I cant even try to find any thing about the p3 that is in any way shape or form a step backwards.
The biggest problem I have had so far was when I could not get one of the camera settings to work yesterday I had to turn off my tablet and turn it back on and then that on setting that was not working right for taking a 5shot group of bracketed photos that was only taking 3 at a time. and then it worked. Not any thing I can even hardly say was any big whoop.
