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.

Customize Chromebook Chrosh Shell Environment

Requirement: Chromebook, Common Sense, Commandline Ablity, 1 hour of time

Dear developers with a spare Chromebook lets inject a little personalization into your Crosh shell with custom fonts, the solarized theme, and extra secure shell options.

Also, keep in mind that the terms Chrosh, Chrosh Window, and Secure Shell all refer to various versions and extentions built around the ChromeOS terminal. Settings that affect the ChromeOS terminal are global.
