Update EOS 40D Firmware

How do I update the firmware for my EOS 40D? Are there any simple instructions? The instructions on the canon website are really confusing.

Hi Txmason!

 

Thank you for posting!

 

First, please make sure you have downloaded and extracted the firmware.  The firmware can be downloaded from the Canon USA website below:

You can update the firmware in your camera by connecting your camera to your computer and using EOS Utility.  Please follow these steps:

Re: Update EOS 40D Firmware

Canon site has rejected my Serial number for some reason.  So:

 

Download the firmware the unzip the .fir file

Format a CF card in your camera

Remove the CF card then connect it to your computer

Copy the .fir to the root of the CF card

Eject the CF card from your computer

MAKE SURE THE CAMERA BATTERY IS WELL CHARGED!!

Insert the CF card in the camera and power on

Go to the Spanner ...    (3rd and bottom option is Firmware ver. n.n.n)

Put the camera down on a surface

Scroll down to this and press the SET button on camera

It should now see the new firmware file and offer upgrade

Follow the menu and let it run through to completion undisturbed

You can look but not touch

On completion, you can reformat the CF card to remove the new firmware file.

The job's a good 'un.
