It's useful to update your firmware - there are new features being added which can sometimes depend on firmware updates.
To update your firmware, follow the directions in the chrome app (go to HELP --> DOCUMENTATION -- UPDATES AND FIRMWARE). Follow the directions for your operating system. Please read the directions and follow them to the T - otherwise it may not work.
You can always confirm what firmware version is installed in the Chrome app by going to DEVICE --> FIRMWARE.
thanks for the hot tips
