Looks like from the log file the update reached ~90% before the M210 was powered down.  Z30 is now inop and no longer functioning.  It runs through its gimbal test, but after that nothing, including movement and video feed.  Retried firmware update and the log file says there in no need to update due to same or newer version.  Any help would be much appreciate.
