About Firmware Update Utility:

Applying a different firmware version than the one already installed on your camera can improve the device’s overall performance and stability, resolve various issues, add support for newly developed features, or recover the device’s functionality from a state you don’t enjoy.

This process isn’t intended to be destructive, but still, it’s best that you 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, the utility basically searches online or in any given location for a compatible firmware file, alerts you if a suitable version has been found, and asks for your approval before initiating the upgrade.

So all that’s left for you to do is to click on the download button, get and install the update tool, and run it in order to search for a different firmware version. Also make sure you check back with our website so that you always know when this utility is able to find a new firmware.

  It is highly recommended to always use the most recent driver version available.

Try to set a system restore point before installing a device driver. This will help if you installed an incorrect or mismatched driver. Problems can arise when your hardware device is too old or not supported any longer.
