Hi and welcome to the forum:

The image, on its own, is not very informative, so explaining what is going wrong would be helpful.

At a guess, I suspect your update is stalled at 99% completion - is that correct?

Thanks for the reply.

It did not reach 100% and resetting with battery removal did not work.

Is your camera able to start up again, or is it now dysfunctional?
Did you have a fully-charged battery and a clean, Full-Sized SD card for the firmware?

Yes, you are right. The camera is dysfunctional. I have followed the instructions in the manual, but still, the issue persists. I have inserted a new battery and an SD card.

Thank you for responding, but you did not answer my questions in order to assist you.
Just to be clear... Will the camera turn on normally? Can you see a display of some kind. For example if, having turned it on, you press the Menu button, do you get to see the menu?

Greetings,

If the FW update did not complete and the camera does not function "dysfunctional", there is no way to reset the camera or its settings to defaults. You will need to contact Canon Support and send it in for service and/or repair.

I have been waiting for an hour, but my device is still stuck at 99% completion. Additionally, the camera is not functioning properly and requires me to remove and reinsert the battery. Even after doing so, I am still receiving the same message and it continues to reach 99% again. None of the buttons on the device seem to be working.

Thank you for keeping me updated about the camera reset. I found a suitable location to have it checked at a repair shop.

Greetings,

No problem. I am very sorry your update didn't complete. Normally its a simple process that completes in a few minutes.

Last attempt. Remove all accessories form the camera. (Example) Lens, grip, etc. Remove the card and battery. Press and hold the shutter button for 20 sec. Replace (insert) only the battery. Power on the camera. If it goes straight to the firmware update (progress), the FW is corrupt, and it will need to be repaired.

Press the menu button and see if the main menus return. I suspect they won't but this would be a final effort to recover the camera. All signs point to an incomplete FW flash.

Hi Farooqi,

Since I'm having the exact same problem in my EOS camera, could you share how did the store managed to fix it (did they assist you remotely, or did you send the camera to them?) did the fix was done easily in place or did they need to take it to the lab? And how much did it cost?

Thanks!
