Firmware Update Failed on the 2nd Canon with Same SD

Recently I've done firmware update on my two old Canon EOS cameras using the same SD card, specifically, EOS 7D and EOS M3.  I did it to M3 first, then 7D.  But the update failed on 7D due to this error:  "Update file cannot be found.  Please check the memory card and reload the battery and try again."

File Not Found During Cannon Camera Firmware Update

There are two (2) ways to fix this.

  1. Reformat the SD card before copying the firmware file into it for firmware update if you don't mind losing all files.
  2. Simply remove or temporally save all  DCIM\CANONMSC\*.CTG file(s) in the SD card to someplace else before firmware update.

I did it with the second approach.  As soon as the camera detected the firmware file, the update went smoothly.

  1. How can I remove the firmware update program because I followed all the rules

    1. Are you referred to the firmware file itself that you copied into the SD card for update? If so, what tool you used and how you copied the file are what you should use and how you could delete the file.

      If you are talking about the built-in program in the camera which picks up the firmware file for update, it would be better to consult with canon and see their development possibilities.
