Here's your Unlocked BIOS.
You have to reinstall the OS through a Flash Drive made by "Chromebook Recovery Utility" and choose your Device Model.

try this and press and hold the Esc + Refresh + power button at once. When the Chrome OS is missing or damaged warning shows up, press and hold Ctrl + D simultaneously. Press Enter if asked to turn OS verification off. If doesn't work, reinstall.
