I recently tried to do a firmware update because my Mavic Pro is "unable to fly" until I finish the update.
I've tried twice now and the update fails when it reaches 100% and restarted the equipment between both attempts.* Attached is a screenshot of the error "reason" (Reason: 0x020b0004)
I've tried the firmware update twice this morning and can't fly my drone until I resolve this.
