Chromecast updates automatically, but you can check the status and restart the device if an update is stuck

Your Chromecast receives updates over the internet without you having to do anything. Google pushes updates to Chromecast devices automatically, usually overnight when the device is idle and plugged in. However, if you want to check whether an update has already been installed, restart the device to unstick a stalled update, or see what version you are running, you can do that through the Google Home app on your phone.

Updates typically take 10 to 15 minutes to install once they begin. During an update, your Chromecast will not respond to casting commands, and the light on the device may blink or change color. You should not unplug the device during an update, as this can corrupt the software.

Key Takeaways

  • Chromecast updates happen automatically when the device is plugged in and connected to Wi-Fi, usually at night.
  • You can check your device's current software version and restart it using the Google Home app on your phone.
  • If an update appears to be stuck, unplugging the device for 30 seconds and plugging it back in will usually restart the process.
  • You do not need to do anything to receive updates—Google sends them to all Chromecast devices on a rolling schedule.

Check your Chromecast version in the Google Home app

Open the Google Home app on your phone or tablet. Tap and hold the Chromecast device you want to check. At the bottom of the screen, tap the settings icon (a gear or three dots, depending on your device). Scroll down to "Device information" or "About." The current software version will be listed there.

If you see a version number but are not sure whether it is the latest, you do not need to compare it manually. Google automatically sends the newest version to your device. If your Chromecast is connected to Wi-Fi and plugged in, it will receive the update within a few days.

Restart your Chromecast if an update seems stuck

If your Chromecast has not updated in more than a week, or if it is unresponsive to casting commands, a restart often fixes the problem. In the Google Home app, tap and hold the device, then tap the settings icon. Look for a "Restart device" or "Reboot" option and tap it. The device will restart in about 30 seconds.

If you do not see a restart option in the app, you can unplug the Chromecast from power for 30 seconds, then plug it back in. Wait for the light to stabilize before trying to cast again. This manual restart will not erase any settings or paired devices.

Make sure your Chromecast stays connected to Wi-Fi

Updates only read when your Chromecast is connected to the same Wi-Fi network as your phone or tablet. If your device has disconnected from Wi-Fi, it will not receive updates. In the Google Home app, tap and hold the Chromecast, then tap the settings icon. Look for "Wi-Fi" or "Network" and confirm the network name matches your home network.

If the device shows "Not connected" or a different network name, tap the Wi-Fi option and reconnect it to your home network. You will need to enter your Wi-Fi password. Once reconnected, leave the Chromecast plugged in overnight so it can read and install any pending updates.

Leave your Chromecast plugged in during updates

Chromecast updates happen most often between midnight and 6 a.m., when the device is less likely to be in use. For this reason, you should leave your Chromecast plugged in and connected to Wi-Fi at night. If you unplug it during an update, the software can become corrupted and the device may stop working until you perform a factory reset.

If you need to unplug the device during the day, check the light first. A steady light means the device is idle and safe to unplug. A blinking or changing light usually means an update is in progress—wait until the light returns to normal before unplugging.

Factory reset your Chromecast if it will not update

If your Chromecast remains unresponsive after multiple restarts, or if the light stays stuck in a blinking state for more than 30 minutes, a factory reset may be necessary. This will erase all settings and paired devices, but it will also clear any corrupted software that is blocking an update.

To factory reset, locate the small reset button on the back or bottom of the Chromecast (it is usually recessed). Use a paperclip or the tip of a pen to press and hold the button for 10 to 15 seconds while the device is plugged in. The light will flash rapidly, then turn off. Wait one minute, then plug the device back in. It will restart and prompt you to set it up again through the Google Home app.

Frequently Asked Questions

How long does a Chromecast update take?

Most updates take 10 to 15 minutes from start to finish. During this time, the device will not cast. Larger updates or slower internet connections may take up to 30 minutes. Do not unplug the device while the update is in progress.

Will I lose my settings if I restart my Chromecast?

No. A restart or reboot does not erase settings, paired devices, or Wi-Fi information. Only a factory reset will erase those things. A straightforward restart is safe and often fixes update problems.

Can I cast to my Chromecast while it is updating?

No. The device will not respond to casting commands during an update. Wait until the light returns to a steady state before trying to cast again.

What if my Chromecast is not on the latest version after two weeks?

Check that the device is connected to Wi-Fi and plugged in. Restart it using the Google Home app. If it still has not updated after another week, perform a factory reset and set it up again. This usually resolves any software issues that are blocking updates.

Do I need to do anything to start an update?

No. Updates are automatic. You only need to make sure your Chromecast is plugged in and connected to Wi-Fi. Google will send the update to your device on its own schedule, usually within a few days of the update's release.
