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.

1. Mastering Functions

A function is a mapping from one set, called a domain, to another set, called the codomain. A function associates every element in the domain with exactly one element in the codomain. In Scala, both domain and codomain are types.

Build Coreboot for ARM Chromebook - C201 Veyron Speedy

These instructions will take you through the step by step process of building and flashing a custom build of the Coreboot ROM to a Chromebook C201.

This guide expects you to have a Chromebook C201, and another ARM computer with Ubuntu installed. Specifically I used the Odroid XU2. You may be able to do this on an Intel platform, using a cross compiler. See the sidenotes section for more information.

Setting up your Ubuntu

Install dependancies

Update your Ubuntu aptitude and install the dependancies we will need.

sudo apt update

How to use matrix.org and vector.im as an IRC client

How to Join an IRC Channel on matrix.org

Join the room #freenode_<#channel>:matrix.org, replacing <#channel> with the name of the IRC channel. For example, in order to join the #prometheus IRC channel, join the room #freenode_#prometheus:matrix.org on matrix.org.

In vector.im, rooms can be joined with the directory symbol on the bottom left.
