I have downloaded the 1.0.2 firmware, but when I try and update, either through the utility or via the SD card, it states I cannot downgrade the firmware. I have 1.0.1 installed currently. Anyone know how to resolve this?

Remove the other card and try again. At least for many users, including me, the update succeeds only when the card that doesn't have the firmware update file is removed from the camera.

Hi Larry,
Greetings. This is a very good point. The old upgrade instructions, at least for my camera (R5 C) specified that you had to use the SD card for firmware upgrades. While it didn't say to remove the second card, most did which ensured the camera was reading the firmware file correctly.
The R5 mkII's instructions no longer state that. It doesn't specify a card type or say which has to be used. I've seen posts from others on various sites who have used their CF ExpressB card for the update successfully. Slowly things are changing since (for example), the R1 has two CF ExpressB slots.
Typically, when the "firmware could not be downgraded" error message displays. It's because an older version of firmware exists in the root of the card the camera is attempting to read from.
In this case, I would look at both of my cards individually and see if v1.0.1 exists on one of the cards. Formatting that card or removing the card that contains the older update should work.
If this is happening with Canon Connect, the version that is being downloaded to the card should be verified. Hopefully this will help others if they're experiencing this issue.
