EOS R5 C Firmware update 1.0.9.1 still running after 45 minutes

I have updated firmware on this camera several times before and never had a problem. This time, the process started, but is still running after about 45 minutes. The instructions indicate it should take about 10 minutes. 

Am I in trouble here??

Greetings,

In trouble.  You might be.  Mine took about 9 min.  This is average.  The update should be performed with a freshly formatted SD card installed.  The CF card should be removed. I use a fully charged battery and usually have a USB- C PD attached. (Though this is not necessary)

Having a lens attached is fine, but I wouldn't have any other accessories attached.  (Flash, grip, etc).

It's important not to touch any buttons once the update process is started. If your update hasn't completed within 10 minutes, it's not going to finish by waiting.  

Here's what I would do.  Open the memory slot cover.  Eject the SD card.  Turn the power switch to off.  Close the cover.  Wait 10 or 15 seconds power on the camera to photo mode.

What is the result?

Now power the camera off. Wait 10 or 15 seconds and try video mode.  What is the result? Check the listed firmware version.  

It will likely be 1.0.8.1 or previous whatever you were running.  If this works (and you'll be very lucky if it does), I'd go through the entire process again. Freshly formatting the card, copying a fresh download from the Canon USA website VSD13.fir, and going through the upgrade process again with a fully charged battery.  I wish you luck.  Let us know the outcome.  I hope you won't have to send the camera in to be reflashed.

Thanks for your response, Rick (shadowsports). It turns out that miracles do happen. After about 2 hours of flashing red light, I went to bed. There was a battery pack connected to the camera, so I figured there was no harm in letting it run as long as it could. When I awakened, 7 hours later, the camera was off and both the in camera battery and the battery pack were discharged. I put a fresh battery in the camera and powered it up in video mode, and the red light began flashing again. I went out to get coffee. When I returned, no more flashing red light. I followed your advice about switching to off, then photo, off, then video. To my astonishment, the firmware indication is 1.0.9.1 and the camera seems to function just fine. No idea why this was a successful update, as everything seemed to heading in the wrong direction. I'll have to go out and shoot some images and video today to verify that the camera functions, but given what I've seen have no reason to doubt that it will. Case closed.....I hope.

Greetings ,

This is extremely good news and one of those "count your lucky stars" outcomes.  Very happy for you.  If you were prompted to set date and time in cinema mode, you should be in good shape.  I recommend you perform an ABB with the body cap on.  Test the memory card extensively to be certain you can count on it.  Again, very pleased to hear you were able to recover.  😊
