How to Update Chromecast to the Latest Version 2025

Updating your Chromecast helps improve performance, strengthen security, and reduce casting issues. Many users never touch the update process because Chromecast normally updates itself. Still, there are times when you may want to check the firmware version, start a manual update, or force a new installation. This guide walks you through everything you need to know about how to update Chromecast, from automatic updates to advanced firmware refresh methods.

How to Update Chromecast Automatically

Chromecast updates itself automatically whenever it remains powered on and connected to Wi-Fi. The device quietly downloads new firmware in the background and installs it once the file is ready. You may see a loading animation on your TV during the installation process.

Keeping your Chromecast updated is important because many connection issues, including the untrusted device message, are often linked to outdated firmware. Leave your Chromecast device plugged in overnight and avoid turning it off frequently. This gives the device enough time to check for updates and complete the installation without interruption.

How to Update Chromecast Manually

You may prefer to take a more active role and start a manual check. Chromecast does not allow users to download firmware files directly, but you can trigger a new update attempt through the Google Home app. This method is helpful when your device appears to be stuck on an outdated version or when you encounter recurring streaming issues. Below is how to update Chromecast firmware manually.
