Disabling SPI write protection, reflashing, and unbricking an Asus Chromebook C201
View asus c201.md

####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.

# This is a hack I wrote to overwrite $1 with the 4th Amendment.
# It's not pretty, it's not fast, but it works.
# If $1 is a device, when it's full, errors will be thrown and not handled.
# If $1 is not a device, the block device that it resides on will eventually
# fill up, if this script is left running.
# The next line will cause the script to exit on any errors, like
# when the device is full. Hey, I said it was a hack.

Relating to https://github.com/cryptocat/cryptocat/issues/502 , I think it is actually a very good opportunity to work on a development/release process that would strenghten the security and reliability of cryptocat software.
------------
The mains goals of these suggestions are:
- More stability of the security-critical code during the development and latest release.
- Better beta testing and less bugs/flaws in stable releases.
- Overall better documentation and making it easier for people to review our choices.
- Make it easier for the community to contribute. Many are willing, let's lower the barrier even more.

## Lines that begin with "## " try to explain what's going on. Lines
## that begin with just "#" are disabled commands: you can enable them
