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.
