How Do You Do a Hard Reset on Chromecast Ultra?

If your Chromecast Ultra isn’t working properly, or you’re planning on giving it away or selling it, then you can perform a hard reset. When you reset a Chromecast Ultra, the device is returned to its original factory state. Any customization is lost, and it’s removed from your Google Home. After you perform a reset, you will need to set up your Chromecast as if it were a new device before it can be used again.

If you don’t want to completely reset your Chromecast Ultra and remove it from your Google Home, you can try a reboot. The process is similar, and you can follow the process below, but select Reboot in step 5 instead of Factory Reset.

Here’s how to reset a Chromecast Ultra:

  1. Open the Google Home app.

  2. Tap your Chromecast Ultra.

  3. Tap the gear icon.

  4. Tap the more icon (three vertical dots).

How Do I Reset My Chromecast Ultra to a New Wi-Fi?

Normally, your Chromecast Ultra needs to be connected to the same Wi-Fi you used to set it up before you can reset it. If it isn’t, you won’t be able to connect to it with the Google Home app and issue the reset command.

If you’ve relocated your Chromecast Ultra or replaced your router and need to reset it to work with a different Wi-Fi network, then you can use the physical reset button. After you reset the Chromecast Ultra, you’ll be able to set it up with your new Wi-Fi network using the Google Home app.

Here’s how to reset a Chromecast Ultra with the reset button if you have a new Wi-Fi network:

  1. Make sure the Chromecast Ultra is plugged in and turned on.

  2. Push the reset button on your Chromecast Ultra.

Where Is the Reset Button on My Chromecast Ultra?

The Chromecast Ultra reset button is located right next to the indicator light, near the hard-wired HDMI cable. If you hold the Chromecast Ultra in your left hand and the HDMI cable in your right hand, with the shiny side of the device pointing away from you, you’ll find the reset button located directly to the left of the hard-wired HDMI cable. It’s set into the bottom half of the Chromecast Ultra, the side with the matte finish, directly below the seam where the matte and shiny portions of the device meet.

The button is a little difficult to push, but you will feel a click when it has been pushed in far enough, and the light should immediately begin to flash orange. It doesn’t take a lot of pressure, but the button is flush with the Chromecast case, so it can be tough to depress using your finger. If you have difficulty pushing the button with your finger, you may find it easier to depress with your fingernail or a small implement like a tweezer or screwdriver.
