Hi can anyone help? I cannot update the new update is not recognised on my car, and I cannot do it by plugging camera into pc, I usually put the update on a memory card, and the camera does the rest, but it says not the correct updater, and doesn't recognise the file at all in downloads, when I connect the camera, and search.

Hey @peterduran Sorry to hear you are having challenges. The outline most believe is the safest and cleanest way to do the update.
To start no lens on the body, fresh battery and a formatted CF/SD card. Only one card, the one that has the firmware loaded should be in camera. The CF card is what I use on my R5 Mk II.
Firmware updates are cumulative so you do not have to update sequentially. What does that mean to you, updates can go straight from v1 > v5, there is no reason to make the updates in between releases if you missed one/some .
Notable elements when updating Firmware:
If you follow the procedures exactly and the update fails you may want to delete the original download from your computer, this includes the file in your download folder. Reformat the card used for the firmware update. Download a fresh file from Canon and attempt the process again with a clean file. Files can become corrupt during the download or the unzipping process.
Please be aware that you can also use the EOS Utility to update camera firmware. The software to download is located in the second section of the application on this linked page: Canon EOS / PowerShot / SELPHY Apps & software
I would like to thank shadowsports and Waddizzle for helping me tighten up this thread. Their contributions are appreciated and valued!

I, too, am having one hell of a time updating my R5 II firmware. If you ever figure it out, please let me know how you did it. Best of luck.

Thank you for the reply, it was just not recognising the file at all, I have resolved it now, by formatting the card and uploading it again.

Hi, I had to format the card again, then put the file on it again, and it worked fine, it was possibly my fault for using the card for trail cams and then popping it in the camera, I didn't want to use my CF express card, as I have some saved things on that.

Thanks to you folks, I have made some progress. However, the camera (R5 II) does not recognize the file on my CF card. Note that there are already four files on that card, and I have no idea what they are. CRM, DICM, Misc & XFVC. I put the unzipped firmware update as the fifth file on the card. Should it be placed in one of the preexisting files?
When I go to the firmware in the camera menu it states that the firmware update must be on the card. It is on the card, but obviously not in the correct place.
Where do I go from here, coach?

"Note that there are already four files on that card,"
The CRM folder is for RAW Movies and inside you will find sub-folders named "reel_*****" and in there you will find *.CRM files. The DCIM folder has your still images, both Raw and JPG or HIF. Misc. is what it is and I'm not sure what Canon stores there, maybe temp files or your saved configurations. The XFVF folder contains the "reel" sub-folders with standard MP4 movie files.
But it sounds like you are doing it right. Extract the file with the "FIR" extension from the downloaded archive, DMG for Mac, ZIP for windows (although ZIP will work on both systems), drop the FIR in the open area of the card (root) not any of the folders, and put it in your camera

To add Newton post make sure that the CF card is the only card in the camera. If you have two cards in the camera it may be looking at that empty card.
