How to Get Chrome OS Developer Mode

Chrome OS Developer Mode is a hidden feature that unlocks advanced functionality for tech-savvy users. This feature allows you to access the command line interface and install Linux applications. It also allows you to disable Google’s OS verification.

However, it is important to note that enabling developer mode will wipe all data stored on your device and require you to set up your Chromebook from scratch. This is why it is essential to back up your data before proceeding.

Enabling Developer Mode on Chrome OS can be a useful step for advanced users who want more control and flexibility over their Chromebook. Developer Mode allows you to access the Chrome OS shell, install alternative operating systems, and make system modifications. However, it’s crucial to note that entering Developer Mode will wipe your device’s data. Make sure to back up your important files before proceeding.

Enable Developer Mode On Chrome OS:

1. Understanding Developer Mode: Chrome OS Developer Mode is a state that allows you to access and modify the operating system at a deeper level. Enabling it is a crucial step if you want to install custom firmware, Linux distributions, or run developer tools on your Chromebook.

2. Backup Your Data: Before you start the process, ensure you back up all your important data. Activating Developer Mode will erase your local data, and having a backup is essential to avoid data loss.

3. Power Off Your Chromebook: To enter Developer Mode, start by turning off your Chromebook completely.

4. Access Recovery Mode: Once the device is off, press and hold the “Esc” and “Refresh” keys simultaneously. While holding these keys, press the “Power” button. This combination will take you to Recovery Mode.

5. Enable Developer Mode: In Recovery Mode, you’ll see a screen with a warning about Chrome OS being missing or damaged. Ignore this warning and press “Ctrl + D” to initiate Developer Mode. Confirm your choice when prompted.

6. Recovery Screen Warning: The system will display a warning screen, informing you that OS verification is off. Press “Enter” to proceed. Remember, entering Developer Mode disables some security features, and you’ll see a warning screen each time you boot.

7. Wait for the Transition: The transition to Developer Mode will take a few minutes. Your Chromebook will reset, and the transition progress will be displayed on the screen.

8. Set Up Chrome OS: Once the transition is complete, you’ll be prompted to set up Chrome OS like a new device. Follow the on-screen instructions to connect to Wi-Fi, sign in with your Google Account, and configure basic settings.

9. Developer Mode Active: After setup, you’ll notice a new “OS verification is off” screen each time you boot. This indicates that Developer Mode is active.

10. Accessing Developer Shell: To access the Chrome OS shell in Developer Mode, press “Ctrl + Alt + T” to open the crosh (Chrome OS Developer Shell). From here, you can run various commands and perform system-level tasks.

11. Disabling Developer Mode: If you want to disable Developer Mode and return to normal mode, you can do so by turning off your Chromebook, pressing and holding “Esc + Refresh,” and then pressing the “Power” button. At the Recovery Mode screen, press “Ctrl + D” to turn off Developer Mode. Confirm the transition when prompted.

12. Linux on Chrome OS (Optional): While in Developer Mode, you can install Linux alongside Chrome OS. To do this, use the “sudo crossystem dev_boot_legacy=1” command in the crosh shell to enable Legacy Boot. After enabling Legacy Boot, you can install a Linux distribution using methods like Crouton or flashing a custom firmware like MrChromebox’s firmware.

13. Cautionary Notes:

  • Be aware that entering Developer Mode has security implications, as it disables some of Chrome OS’s built-in security features.
  • Chromebooks in Developer Mode may boot more slowly, and you’ll see a warning screen at each boot.
  • Make sure to read and understand the implications of Developer Mode before proceeding, as it involves potential risks.

How to enable developer mode

There are many benefits to developer mode, including access to advanced features and Linux applications. However, it is important to remember that developer mode will remove some of the built-in security features of your Chromebook and may make it more susceptible to malware. It is also important to remember that enabling developer mode will wipe all data on your device and will void your warranty.

To enable developer mode, turn off your Chromebook and then press and hold the Esc key, the Refresh key (normally where F3 would be on a keyboard), and the power button simultaneously. When the Chromebook reboots, press Ctrl+D.

Once in developer mode, you will be able to use the Chromebook’s command-line interface and install apps that are not available in the Google Play store. You will also be able to modify system files and install alternative operating systems. This mode is not for beginners and should only be used if you have the proper technical knowledge.

What is developer mode?

Developer mode is a special mode that allows you to access the root file system and run programs on your Chromebook. This can be useful for developers and advanced users who want to make changes to the operating system or experiment with different features. However, it is important to note that this can also open your device up to security vulnerabilities and may result in data loss.

To enable developer mode, you must first power off your Chromebook. Then, press and hold the Esc and Refresh keys (usually the fourth key on the top row with an arrow circling it) on your keyboard. Once you have held these keys down, press the power button to turn on your device. Developer mode will then be enabled and you will see a message that says “OS verification is off”. This will disable the security features of your device, making it less secure and more vulnerable to attacks.

What are the benefits of developer mode?

Developer mode is a great feature for advanced users and developers who want to take advantage of the full capabilities of their Chromebook. It allows users to modify the device, install other operating systems, and access a command-line interface. It also allows users to create custom scripts and increase productivity with their Chromebook.

However, it is important to remember that developer mode may void the warranty of your Chromebook, and can lead to hardware or software problems if used improperly. It is also important to backup all data on your Chromebook before enabling developer mode.

To disable developer mode, press and hold the ESC and Refresh keys, then the Power button. When the message “OS verification is off” appears, press the Space bar. This will trigger a factory reset and erase all data on your Chromebook. To re-enable OS verification, press and hold the ESC and Refresh buttons again. This will return the Chromebook to a normal state.

What are the risks of developer mode?

Chrome OS Developer Mode is a hidden setting that allows you to access advanced features on your device. This can include a command line interface, the ability to install Linux applications, and more. However, there are also some risks to be aware of.

For example, enabling developer mode can make your device less secure and can lead to data loss. It can also void your warranty, so it’s important to be careful and only enable it if you’re comfortable with the risks.

To enable developer mode, switch off your Chromebook and then press and hold the Esc and Refresh keys simultaneously. Once the device restarts, it will display a warning screen saying that Chrome OS is missing or damaged. When prompted, press the space key to turn off OS verification. You’ll then see a message indicating that the device is in Developer Mode. From here, you can run commands and access the root file system.


Enabling Developer Mode on Chrome OS opens up a range of possibilities for advanced users, allowing them to customize their Chromebooks beyond the standard user experience. However, it’s crucial to proceed with caution, understanding the risks involved and taking appropriate measures, such as backing up data, before making any significant changes to the system.
