How to Update Your Chromecast Firmware Automatically

Google automatically pushes out new Chromecast firmware, so in most instances you should have the latest available version. However, such rollouts are often staggered, so the latest firmware version may take time to install. Here’s what you can do to try and prompt an automatic update.

1. Go to Google’s Chromecast support page to check the latest firmware version available for your Chromecast device.
2. If you haven’t already, download the Google Home iOS app or the Google Home Android app .
3. Ensure your Chromecast is powered on and ready to receive a Cast signal.
4. Make sure your smartphone and your Chromecast are both connected to the same Wi-Fi network.
   To quickly check both your smartphone and Chromecast are connected to the same Wi-Fi network, open a cast-enabled app such as YouTube and tap theCast icon. Your Chromecast device should appear. If it’s not showing, you may need to reconnect your Chromecast to the network.
5. Open the smartphone app and locate your Chromecast device, then tap the device icon to get an overview of it.
6. Tap thegear icon to open device settings.
7. Scroll to the bottom of the page to reveal the Cast firmware version. This is the current firmware your device is running.
   
8. Compare your device’s firmware with the latest available version on Google’s Chromecast support page (step 1). If the firmware version on the Chromecast support page is newer (a greater number) than the build you have on your device, you can try to encourage an automatic update via the Google Home app.
   If both versions are the same, you have the latest available firmware and don’t need to do anything else.
9. To try and encourage an automatic update, make sure you’re still in the Device settings page (step 5).
10. Tap thethree horizontal dots icon.
11. A pop-up window will launch with additional options. TapReboot to reset your Chromecast device .
    
12. Your Chromecast dongle will shut itself down and automatically restart. During this process, it will try to download and install the latest available firmware.
13. If the firmware is available, the installation process will show on your connected TV.

15. To check your Chromecast is now running the latest firmware, repeat steps 3 through 5.
    As noted, Google rolls out firmware updates in stages. If the update hasn’t yet landed for your device, wait a few days and try the process again.
16. That’s it! Your Chromecast should now be automatically updated.

How to Force a Chromecast Firmware Update

If new Chromecast firmware is available, but your device hasn’t updated, you can try to force your Chromecast to download it.

This process is a little more complicated than an automatic update, and it’s not guaranteed to work. However, it’s certainly worth trying if you can see the firmware is available but it hasn’t yet pushed to your Chromecast.
