Recover your Chrome device

Install a new version of the Chrome operating system on your Chrome device by going through the recovery process. You may want to go through this process if you’re having problems updating your Chrome device or if your Chrome device stops working.

All account information and data stored on your Chrome device, such as photos, downloaded files, and saved networks, will be deleted. Owner privileges for your primary account will also be reset. However, the actual Google Accounts and any data synced to these accounts won't be affected by the recovery process. After the recovery process is completed, you’ll be guided through the initial setup again.

 

What you'll need

Before starting this process, you'll need the following:

• A Chrome device, Windows, Mac, or Linux computer with administrative rights.
• A 4 GB or larger USB flash drive or SD card that you don't mind clearing.

Step 1: Check for the “Chrome OS is missing or damaged” message

If you see this message when starting your computer, please proceed to Step 2.

If you see the "Chrome OS verification is turned off" message, see the Chrome OS verification is turned off article.

If you don’t see either messages above but still want to recover your Chrome device, trigger this screen by pressing the recovery button on your Chrome device. Turn off your Chrome device, press this button, and while keeping it pressed, turn on your Chrome device again. In some cases, you'll need to poke the button by using a pin.

Step 3: Reinstall the Chrome operating system

1. Start your Chrome device.

3. Wait for the Chrome device to boot up from the flash drive.
4. Follow the instructions that appear on the screen.
5. On successful installation of the Chrome operating system, you will be prompted to remove the USB flash drive or SD card.
6. Remove the USB flash drive or SD card when prompted, and your Chrome device will automatically restart.

You should now be able to start your Chrome device as normal. Because the data stored on your Chrome device has been cleared, you'll need to go through the initial setup again. Make sure you sign in with your primary Google Account, because this account will be set as the owner account.
