Chromecast update is taking longer than expected

To enjoy the latest and greatest features available on Chromecast, your device may need to update to the most recent software version. The update can take up to 10 minutes.

To update successfully, follow the steps below:

  • Ensure your TV is powered on.
  • Ensure the Chromecast is tightly plugged into the HDMI input in your TV.
  • Ensure the Chromecast is tightly connected to the power supply and the power supply is plugged into the wall outlet.  

Look at your TV to check the status of the update.

The update is still installing on the TV

When the update is installing, a blue screen will appear on the TV with a spinner and % progress in yellow next to it. Wait for the update installation.

Once your Chromecast has finished updating you will get a “Ready to Cast” message on the TV and the Chromecast will also be shown in the device list of the Google Home app.

The "Downloading/fetching update" message appears for a long time

If the download is moving forward but moving slowing, give the download 20-30 mins to download. It is possible that your internet speed is slow. If the download is stuck at a certain % for a long time, there might be something wrong in your router settings. There is known issue with certain router configurations that can cause slow downloads.
