How to create “Chromebook Recovery USB” from Ubuntu Linux PC and save image for later use

Google has provided “Chromebook Recovery Utility” Chrome app to create Recovery USB/SD card Media to restore Chromebook to Factory Reset state. Usually Powerwash in Settings of Chrome can also restore back – it just restore back the Chrome OS installation. But this Chrome app utility will restore back the entire SSD to factory reset state (i.e., capable of wipe out all Linux paritions if you had installed ChrUbuntu, so that you claim back entire SSD for Chrome OS again).

chrome-osBut unfortunately this Recovery Utility Chrome app is not supported in Linux OS such as Ubuntu, Linux Mint, Fedora, Debian, etc. (it works in Windows and Mac Chrome browser installations only). As a developer friendly Google, there is an official Linux script to do this which is hidden inside this Recovery Help Page from Google.

What you need?
  1. Minimum 4GB USB Pen drive or SD Card
  2. Linux Computer (Chrome browser is not necessary)
How to do it?
  1. Download the Recovery script from Google official Repository here.
  2. Run: $ chmod 755
  3. Run: $ sudo bash
  4. Answer prompts sincerely – plug in USB Drive / SD Card while prompted, you are done!
  5. Remove the Media from Linux PC.
  6. I assume your Chromebook already shows “Chrome OS is missing or damaged” error screen. Shutdown Chromebook. Plug in Recovery Media we prepared.
  7. Power on Chromebook. It should automatically detect the Recovery media and start recovering. Hey! Now you have Fresh Chrome OS installation wizard!

Here are the Linux terminal session logs for your reference:

Shall I remove the temporary files now? [y/n] y

The recovery image is downloaded in a temporary directory under /tmp path. Before completing the script, you can copy this image to other directory for archival purpose if you need. Here is Linux terminal log for the same:
