I HAVE A M300 RTK, LAST DAY IT ASK ME TO UPDATE SOME MODULES  OF THE DRONE AND I DID IT, LATER IT ASKS FOR RC UPDATE, I ALSO INSTALLED V 05.01.0200. THEN IT ASKED FOR THE AIRCRAFT UPDATE, BUT IT GETS STUCKS AT 87%, I TRIED TO INSTALL IT ABOUT 10 TIMES UNSUCCESFULLY. THEN I TRIED TO GET BACK IN VERSIONS OF THE FIRMWARE AND HAPPENS AGAIN THE SAME THING AT 87% THEN THE MESSAGE ERROR (UPGRADE TIMEOUT, DEVICE DID NOT RESPOND (1-0-6)

AFTER RUNNING PROCESS SERVERAL TIMES IN COMPUTER DJI ASSISTANT, IN THE REMOTE CONTROLLER, DOWNLOADING THE FIRMWARE AND DOING AN OFFLINE UPDATE IT GET STUCKED

WHEN I FORCE SHUTDOWN CLICKING POWER OR DISCONECTING BATTERIES IT STARTS AGAIN WITH A LOT OF PROBLEMS, IT SAYS IT HAS VERSION 05.01.0100. IT DOES NOT RECOGNIZE BATTERIES IT SAYS BATTERY AUTHENTICATION FAILED, IT SAYS LEFT BATTERY IS NOT INSTALLED AND SO MUCH MORE PROBLEMS THE THING IS I CANT FLY.

THE QUESTION IS
IS THERE ANOTHER WAY TO UPGRADE FIRMWARE? ANY CLUE ON HOW TO FIX THIS PROBLEM

THANK YOU
