Change the Serial Number on a Chromebook

    Follow

    The Chromebook will need to be deprovisioned so you can enter Developer mode.

    Ener Dev Mode:

    This will wipe your local data, so make sure to back anything up that you don't have stored in the cloud. To put your Chromebook in Developer Mode:

    1. Press and hold the Esc and Refresh keys together, then press the Power button (while still holding the other two keys). This will reboot your Chromebook into Recovery Mode.
    2. As soon as you see Recovery Mode pop up—the screen with the yellow exclamation point—press Ctrl+D. This will bring up a prompt asking if you want to turn on Developer Mode.
    3. Press Enter to continue.
    4. Press Ctrl+D - give it some time. It'll pop up with a new screen for a few moments, then reboot and go through the process of enabling Developer Mode. This may take a little while (about 15 minutes) and will wipe your local information.
    5. When it's done, it will return to the screen with the red exclamation point. Leave it alone until it reboots into Chrome OS.

    Serial Change Steps:

    1. Remove the R W screw from the motherboard
    2. After it boots into developer mode, press CTR+ALT+F2 the key, this should open a terminal
    3. In the terminal type "chronos"
    4. Then "sudo su"
    5. Then "vpd -l"


    This will list a bunch of information. You might see something called "serial_number" and "mlb_serial_number" depending on the chromebook. 

    To change an entry do the following:

    Example Code:
    'vpd -s "entry"="0"'

    vpd -s "mlb_serial_number"="enter your preferred serial"

    vpd -s "serial_number"="enter your preferred serial"

    After that type "dump_vpd_log --force"

    Then verify that the serial numbers have changed by typing "vpd -l" again

    Then reboot the chromebook by pressing REF+POW
