Google Chromecast is a USB device that lets you stream movies, TV shows, and other content. In case you ever have trouble streaming media, you should know how to reset a Chromecast device. You may also want to factory reset your Chromecast before you sell it or give it someone else.
Instructions in this article apply to first-generation and second-generation Chromecast and Chromecast Ultra devices.Google
How to Reset a Chromecast
Before you begin, make sure your Chromecast is securely connected to an HDMI port on your television. The device should also be connected to a power source and your Wi-Fi network. If the device still doesn't work properly, take the following steps to perform a factory reset:
You must be connected to the Wi-Fi network you originally set up your Chromecast on for this process to work.
Open the Google Home app on your Android or iOS device.
Tap your Chromecast device.
Tap the Settings gear.
On Android, tap the three dots in the upper-right corner. On iOS, tap Remove device.
Tap Factory reset.
A warning message displays, asking if you're sure you want to reset the device to factory settings. Tap Factory reset again to confirm. Your Chromecast is reset to the state it was in when you first took it out of the box.
A factory reset clears all your installed apps and personal settings. There are a number of other steps you can take to fix a Chromecast that isn't working.
How to Reset an Older Chromecast
If you have an older Chromecast that uses a computer to configure its settings as opposed to a smartphone or tablet app, open the Chromecast application that was initially installed on the desktop or laptop when you first set up the device.
When that application interface is visible, choose the Chromecast that you wish to reset, then select Settings and Factory Reset to return the device to a like-new state.
How to Perform a Hard Reset of Your Chromecast
If the above directions did not do the trick for some reason, the last resort is to perform a hard reset on the device. While the Chromecast is connected to a TV and a power source, press and hold the button located on its side until the LED light on the device flashes white and the TV goes blank. At this point, release the button and wait for Chromecast to complete the restore process.
If you followed these methods and your Chromecast is still not functioning correctly, the hardware may be defective. Contact the Google Help Center for further assistance.
