1) Once the EOS-1D X camera is updated to Version 2.0.9, it cannot be restored to a previous firmware version (Version 1.0.2 through 2.0.8).
2) It is recommended that the latest application software*1 be used, once the EOS-1D X is updated to the firmware Version 2.0.3 (or later) from older firmware (Versions 1.0.2 through 1.2.4). Certain previous versions of these applications do not support functions which are added by the new firmware.
3) Accompanying the enhancements to the functions, the instruction manual has also been revised. Users are asked to download both the latest firmware and the instruction manual. You can download the latest instruction manual from our Web site.
4) As a result of this fix, cameras with Firmware Version 2.0.7 (or later) will not be able to read the "camera settings file" created with cameras running Firmware Version 2.0.3 (or earlier). If you require the "camera settings file", please create it after updating to firmware version 2.0.7 (or later).
Updating to a newer firmware version than the one already installed on your camera can improve the device’s overall performance and stability, resolve various issues, and add support for newly developed features or enhance existing ones.
On the other hand, downgrading the camera’s firmware can recover its functionality in the unlikely event the currently installed version is faulty or the device’s performance dropped after an upgrade. However, bear in mind that applying an earlier build might not always be possible.
It is recommended that changing the camera’s firmware be performed when the new release resolves an issue that your device has been encountering, or adds a new feature (or enhances an existing one) that could prove useful for you.
This process isn’t intended to be destructive, but still, it’s best to save all your personal data and configurations before applying a different firmware. Moreover, make sure that the battery is fully charged and don’t use the camera’s buttons while the installation is in progress.
When it comes to the update method, usually, you must copy the firmware file onto a compatible memory card, insert it into the camera, and browse from the menu to the device’s update section.
However, each device has various ways to enter the update mode and particular steps that should be taken for a successful upgrade, therefore make sure you read the product’s installation guide.
That being said, if you consider that this firmware improves your device in any way, then hit the download button and get the desired version; if not, check with our website as often as possible so that you don’t miss the update that will boost your camera’s performance.
