Enabling Developer Mode

To unlock the capabilities of your Chromebook beyond its default settings, enabling Developer Mode is the key. This mode allows you to run software and commands that aren’t part of the standard Chrome OS experience.

Detailed Steps:

  1. Back up your data. Enabling Developer Mode will erase all local data on your Chromebook. Make sure any important files are backed up to Google Drive or another cloud service.
  2. Begin with your Chromebook turned off.
  3. Hold down the Esc + Refresh (F3) keys and press the Power button. This will reboot your Chromebook into Recovery Mode.
  4. Press Ctrl + D when the recovery screen appears (you’ll see a yellow exclamation point).
  5. Press Enter to turn off OS verification. This will prompt a screen that tells you OS verification is off, accompanied by a loud beep.
  6. Press Ctrl + D or wait 30 seconds to proceed. Your Chromebook will now transition into Developer Mode. This could take some time, usually around 10 to 15 minutes.
  7. Set up your Chromebook again. Once in Developer Mode, your system will reboot, and you’ll go through the initial setup process.
  8. Developer Mode is now enabled. Enjoy your newly unlocked Chromebook.


Enabling Developer Mode can be immensely powerful, equipping you with the tools to tinker with your device’s full capacities. The benefits include running alternative operating systems, accessing a deeper layer of Chrome OS, and developing new software. However, the downsides are significant; you will void your warranty, and your device’s security will be compromised as certain protection features are bypassed.

Using the Crosh Shell

While in Developer Mode, you have access to the Crosh Shell, a local command line interface for Chrome OS.

Detailed Steps:

  1. Press Ctrl + Alt + T to open the Crosh Shell in a new browser tab.
  2. Explore various commands such as shell to access the full Unix shell, help to see a list of available commands, or ping followed by a web address to check network connectivity.
  3. Use the shell for advanced tasks, like ping tests, network diagnostics, or ssh to securely connect to a remote server.


Gaining access to the Crosh Shell through Developer Mode gives you a level of control over your device more akin to traditional operating systems. This is an invaluable tool for troubleshooting or developers. On the flip side, it’s a gateway to potentially make system-level changes that could affect your Chromebook’s functionality.

Powerwash: Resetting Your Chromebook

If you test the limits with Developer Mode and need to revert to a stable state, Powerwashing returns your Chromebook to factory settings.

Detailed Steps:

  1. Backup your data. Powerwashing will erase all local data.

  3. Click on ‘Advanced’ at the bottom of the Settings window to expand the menu.
  4. Under ‘Reset settings’, click on ‘Powerwash’ and then ‘Restart’.
  5. Follow the on-screen prompts to reset your Chromebook to its original state.


Powerwashing is like hitting the reset button on your Chromebook; it can solve many issues by returning the device to its original configuration. Although it’s a useful feature, be mindful that you’ll lose all local files not backed up elsewhere.

Installing Linux Applications

With Developer Mode activated, installing Linux applications becomes possible, which traditionally wouldn’t run on Chrome OS.

Creating Recovery Media

Before diving into Developer Mode, creating recovery media for your Chromebook is a sensible precaution.

Detailed Steps:

  1. Insert a USB drive or SD card into your Chromebook. Ensure it’s at least 4GB and that you have backed up any files from it as it will be formatted.
  2. Open the Chrome browser and install the ‘Chromebook Recovery Utility’ from the Chrome Web Store.
  3. Open the utility and follow the instructions to create a recovery image for your specific Chromebook model.


Creating a recovery drive provides a safety net if you encounter any issues in Developer Mode. While it takes a little time and a spare USB drive, the peace of mind knowing you can restore your Chromebook is often worth the effort.

Accessing Full Chrome OS Shell

Developer Mode lets you access the full Chrome OS shell for more advanced customization and control.

Detailed Steps:

  1. Enable Developer Mode following the earlier instructions.
  2. Once Developer Mode is enabled, open the Crosh Shell by pressing Ctrl + Alt + T.

  2. Reboot your Chromebook and wait for the screen with the red exclamation mark.
  3. Press the spacebar when prompted to re-enable OS verification.
  4. Follow the on-screen instructions to restore the system to its default, secured state.


Disabling Developer Mode reinstates all security features and functions of your Chromebook, but it also deletes all your data in the process. It returns your device to its secure, streamlined state.

Detailed Steps:

  1. Insert the bootable USB device into your Chromebook.
  2. Press Ctrl + U at the startup screen to boot from the USB device.


This ability is extremely handy for those wishing to trial new operating systems or run live versions of software. However, booting unfamiliar software can potentially harm your system, so proceed with caution.

Enhancing Your Chromebook’s Performance
