Im getting reports that users are having ftp access errors or ftp timeout errors when trying to rollback from the 1.04.0100 firmware using the dumldore tool. Usually this is because the Mavic gets the wrong IP address and can't connect to the aircraft. This will show you how to manually set the proper IP address to fix.
