Before I upgrade, can someone confirm that the md5 checksum for the .fir file is..
Not sure why Canon don't publish this rather than just the file size.
After having upgraded the firmware across many cameras through the years, it is almost 2nd nature now to just download, unzip, copy file to root of card, and put it in a camera with a fully-charged battery. I believe the upgrade process within the camera will also do a preliminary check of the file with its header to validate the file.
With today's more secure download tools, I no longer really have had a need to check checksums of files, as many tools already do that to provide guaranteed delivery to the end user, like FTP, browser support, etc.
