To factory reset your Google Chromecast, follow these steps using the Google Home app:
- Open the Google Home app on your smartphone or tablet.
- Tap and hold the tile representing your Chromecast device.
- Tap "Settings", then tap "More".
- Finally, tap "Factory reset", then confirm by tapping "Factory reset" again.
- Wait for the reset process to complete. This may take a few minutes.
- Once the reset is complete, you'll need to set up your Chromecast again as if it were new.
This process will erase all personal settings and data from your Chromecast, returning it to its original factory state. This can be useful for troubleshooting issues or preparing the device for a new owner.
