Wookong M latest upgrade

[flybywire]

Hi

I've just had a slight brush with the latest DJI Wookong M firmware/assistant software-5.24/2.02.  I attempted to update the firmware (like a good boy should) plugging my micro USB cable into my new Bluetooth LED module, it failed every time!   :'(  Several reboots and a re-install later, I finally shrugged off this heat induced brain lapse and plugged the cable direct into the main controller unit (as before b/tooth), yes, it worked, now runs latest fware. 
Probably says this on dji's website, but don't read such stuff!  Now I have added new serial number for 1 waypoint function(at last!), it's off to plan a route between A&B!! :laugh:
