Re: Canon 200-400 Firmware - Any issues during/after update?

I obtained my EF 200-400mm L 1.4x used from BandH this past week. S#1100000237 came with version 1.0.0 firmware. As usual, having updated firmware in my 60D and 80D in the past, I went to the Canon Support page and downloaded the updated firmware to a 4GB card formatted first in the computer (Win 10) which showed the requested file but although my 80D recognized the file, it would not update. Then I formatted in the camera and copied the file from my computer onto the card. New file recognized and successfully loaded to the lens.
