                Disabling SPI write protection, reflashing, and unbricking an Asus Chromebook C201
              
          
    ####Disabling SPI write protection
Put the Chromebook in developer-mode:

With machine powered off, hold down Esc and Refresh(F3) while hitting power button
At warning prompt, hit Control+D, then Enter at prompt about enabling developer mode
Machine will format itself

Now remove the write-protect screw to enable flashrom to flash new Coreboot/Libreboot.
Flip powered-off machine over and remove 8 philips-head screws. 2 are located under rubber feet.
