To update the firmware on a Yealink T46S, first download the latest firmware version from the official Yealink support website. Then, access the phone’s web interface by entering its IP address in a browser, navigate to the "Upgrade" section under the "Settings" tab, and upload the downloaded firmware file to initiate the update process. Make sure not to power off the device during the update.
