How to enable developer mode on a Chromebook

Before you Start

Caution: Modifications you make to the system are not supported by Google, may cause hardware, software or security issues and may void warranty.

Couple of things to note -
  1. You will have to turn of verified boot which mean you or anyone can install a custom (non google verified) image.
  2. This will give you access to root console/shell.
  3. All your local data will be erased. Your device will be essentially reset. All your cloud data will still be present.
So to sum up your device will be less secure. Do this on your own risk.

NOTE : This article in intended only for developers and advanced users.

If you are concerned about anything mentioned above this would be a good point to turn back.

How to enable developer mode on a Chromebook

  1. Press and hold 'Esc' and refresh key (the button with a circular arrow - which is in place of your F3). Holding these buttons press your power key.

  2. You should now see a recovery mode screen with an exclamation icon. Press 'Ctrl' + 'D'. You will see screen displaying press Enter to turn of OS verification.

  3. Press Enter. You will see a transition screen displaying message of transition to developer mode.

  4. After some time your device should reboot and start in developer mode. At the end you should see your normal setup screen with language, keyboard layout etc.

How would you test that you are in developer mode?

  • First of all you should be able to access shell (console). Press Ctrl + Alt + T. Then in opened console type shell. You should be getting access to your normal linux command line.

  •  You can also check your chrome setting. You should be able to see all new advanced setting available. You can also see Android internal setting here. You can very well go ahead tab on Build number in About devices and turn on Android developer mode to access developer options. You can use this to turn on USB debugging and adb.

That's it you are now in developer mode. You have root access and can do more cool stuff. But remember  - With great power comes great responsibility :)

NOTE :  If Ctrl + D is not working you  can press Refresh+Power to boot in developer mode with ctrl+D or hit space and wipe clean.
