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. 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.

Moreover, make sure that the battery is fully charged and don't use the camera's buttons while the installation is in progress. 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. 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. However, bear in mind that applying an earlier build might not always be possible. 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. 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.
