How do you factory reset a Chromecast?

A Google Chromecast is a cheap and simple way to beam content from a computer or smartphone onto your TV. However, if something goes wrong or you plan to sell the device, you may need to factory reset the Chromecast.

In this guide, we’re going to show you how to do just that, no matter which version of the Chromecast you have. By the way, click on the link if you’re looking to mirror your iPhone screen on your TV.

Whichever device you’re using, there’s one universal method to reset it and that’s via a connected mobile device. The exception to this is the Chromecast with Android TV, which is detailed further below. For all other Chromecasts:

1. Open the Google Home app
2. Click on the appropriate Chromecast device
3. Now press the Settings icon (the cog in the corner)
4. At the top right, select More (the three dots) and, finally, Factory Reset

Factory reset a Chromecast without a connected mobile

If you haven’t got a mobile device connected to the Chromecast, you can still factory reset with the button on the device. Here are the instructions for each model:

Chromecast (1st Generation)

The 1st generation Chromecast is the rectangular version that you can see to the right.

1. While the Chromecast is plugged into the TV, hold down the button on the side (just next to where the USB cable plugs in) of the Chromecast
2. The LED will blink orange
3. When the LED light turns white, release the button
4. The device will then reset

Chromecast (2nd & 3rd Generation and Ultra)

The 2nd Generation, 3rd Generation and Ultra versions of the Chromecast are all circular and have a built-in cable for the HDMI. The 2nd Generation is shown here.

1. While the Chromecast is plugged into the TV, hold down the button on the side for at least 25 seconds or until the LED light starts flashing red
2. Once the LED light turns blinking white and the TV goes blank, release the button
3. The device will then reset

Chromecast with Google TV

Chromecast with Google TV makes use of a separate remote, rather than your own device (such as a phone, tablet or laptop) for controlling the output. It should look like the image to the right.

1. While the Chromecast is plugged into the TV and powered, press and hold the button on the back of the Chromecast
2. The LED will start blinking yellow
3. When the LED light turns solid white, release the button
4. The device will then reset
