It seems like everytime I need to do an update on the P4P, I get to 99% and the update stalls out and never shows 100%. After 10min or so at 99%, I shut everything down, unplug cables, and then plug back in and start controller then aircraft like ready for a flight and it then shows aircraft status as updated. Does anyone else have this problem, or am I doing something wrong during the update? I always start the update process on fully charged battery and controller. Thanks for any advice.
