How to recover:
This is covered in the Google pages shown here but I have reproduced them below as things change on the internet and instructions go missing.
Recovery option 1: Use the Internet
- On your Chromebook, select Recover using internet connection and follow the on-screen instructions.
- Shortly after you complete the instructions, your computer automatically restarts to complete recovery.
- Important: If you decide to choose a different recovery method at any point while you work on the instructions, press and hold Esc + Refresh , then press Power .
If your computer doesn’t have internet access or the option to recover with the internet doesn’t appear, you may be on an older Chromebook that doesn’t support this feature. Continue to
Recovery option 2: Use A USB Recovery Media
Step 1: Download a new copy of the OS
On the working computer, not the Chromebook with the error:
- If you’re using a Mac or Windows computer:
- Install Chrome.
- Open Chrome Chrome.
- Install the recovery extension.
- To open the recovery extension:
- At the top right of your browser window, click Extensions .
- Select the Chromebook Recovery Utility extension. If the extension popup doesn’t automatically appear on your screen, make sure it’s turned on.
- Click Get started.
- Click Select a model from a list, or type in the model number of the Chromebook you want to recover. To find this number, look at the bottom of the error message on your Chromebook screen.
- Click Continue.
- Insert your USB flash drive into the working computer.
- In the dropdown menu, choose your USB flash drive.
- Click Continue and then Create now.
- When you get a message that your recovery media is ready, remove your USB flash drive from the computer.
Recovery option 3 : Use A Linux PC
- On the Linux computer, download the Recovery Tool.
- Change the script permissions to allow execution with the following command: $ sudo chmod 755 linux_recovery.sh
- Run the script with root privileges with the following command: $ sudo bash linux_recovery.sh
- Follow the on-screen instructions to create recovery media.
- To continue to recover your Chromebook, follow the steps above.
Recovery option 4: If you can still log onto the Chromebook
It is possible one of the issue you face may be fixable using a Mr ChromeBox Script : https://mrchromebox.tech/#fwscript
