Deprovision a Chrome Device
When a device is returned to CTL you must deprovision the device to allow for repairs to happen. It is very likely, to service you as fast as possible, that a replacment device will be sent back to you that has a different serial number.
Here are the steps to deprovions the device from Google:
Deprovision Chrome devices
To manage Chrome devices, admins first need to enroll the devices to their domain. Once enrolled, admins can view their devices in the Google Admin console and deprovision devices that are no longer in use, including Chrome devices that are returned or obsolete. Remember when using the Forced re-enrollment policy to deprovision devices that are no longer managed by your domain.
Chrome devices that have been enrolled display a status of Provisioned within the device list. The last sync time indicates the most recent time it has synced the device policies you set in the Admin console.
Deprovision Chrome devices
To remove devices that are no longer active and to clean up your Admin console, you can deprovision Chrome devices. Deprovisioning removes the following from the selected devices:
- Device policies
- Device-level printers
- Access to Kiosk Mode (including Public Sessions)
- Ability for the device to be enrolled in the domain
Do the following to deprovision the devices:
- Sign in to the Admin console at https://admin.google.com.
- Go to Chrome devices > Devices.
- In the device list, select the provisioned or pending device(s).
- Click More Actions and choose Deprovision.
- Choose "Same Model Replacement"
- In the warning message that appears, click Deprovision to complete the process.
- To view the list of deprovisioned devices, select Deprovisioned as the view option at the top left of the device list.
- The deprovisioning process does not affect the licenses used for Chrome device management. Once a license has been used, the license can’t be revoked and used by a different Chrome device.
- To provision the device again in the future, admins must follow the steps in the re-enrollment section.

Before using the utility, make sure that you have:
- A flash drive or other storage media that can hold at least 4GB and that you don't mind clearing.
- An extra Chromebook, Windows, or Mac computer with administrative rights and Chrome browser installed.
Create recovery media
If your Chromebook isn't working properly, you can use an extra Chromebook or another Windows or Mac computer to create recovery media. Otherwise, you can follow these steps on your Chromebook if you want to create recovery media to use later.
If you're using a Linux computer, follow the instructions listed after Step 6.

- Two options:
- Type in the model number of the Chromebook (ENGUARDE C3A for the CTL Chromebook) you want to recover to get the correct recovery image. You can find that number at the bottom of the error message on your Chromebook or on the recovery screen in the app. It downloads the large file each time you create an image. For multiple USB drives use the next step.
- Download the CTL Chromebook image file. Click the "gear" at the top right in the Chromebook Recovery Utility and select "Use Local Image".
- Click theContinuebutton.
- Insert yourstorage media into an open USB or SD Card port on yourChromebook or on your Windows or Mac computer. The tool will automatically detect the media.

The Chromebook Recovery Utility partitions the USB or SD media into different sections, which means you can’t store data on it unless you wipe the drive clean.
You can use theChromebook Recovery Utilityto erase the recovery files and partitions so that you can use the USB or SD media for storage again:
- Open the Chromebook Recovery Utility app and click the settings icon.
- SelectErase recovery media.

After you see the message saying that your recovery media is prepared for formatting, you may remove it from your Chromebook and format it using a tool provided by your operating system.
