I just "upgraded" to the new firmware, ver 3.16. My Phantom is now completely useless, delivering a constant Red-Yellow flash. It keeps telling me to calibrate. When I begin the advanced calibration, I get a MC Temperature error. I followed instructions, letting it set for 10 minutes, only to get the same error again. I repeated this several times with the same results. I even resorted to placing the Phantom in the freezer for a few minutes, then attempting to calibrate. Same results, MC Temperature too high. Any suggestions? Box it up & send it back to DJI? Throw it out? I'm not only out the money I spent on it, I'm also now losing money in unrealized earning because I can't rely on it to work... ANY suggestions appreciated.
