So, it turns out that you need to overwrite the default firmware on the Chromebook in order to install one that will allow you to boot from external media and install an alternative OS.
My first attempt revealed that the manufacturer of this particular Chromebook had made the BIOS ‘read only’, but I learned that it was possible to bypass this by disconnecting the internal battery.
No big deal. I’ve had this thing apart before. Off to iFixIt I go:
ASUS Chromebook C523NA is a Chromebook laptop manufactured by ASUS that was released on October 23, 2018 and is compatible with the Google Play Store2. It is the first ASUS Chromebook to feature a NanoEdge design, for a larger screen but more compact design.
So after some reading I found a site offering a pretty straightforward tutorial on how to jailbreak and install other OSs on Chromebook. Apparently people are installing Linux, Windows and even MacOS on these things!
Today’s fuckery:
A few years back we bought my son a Chromebook for his schoolwork. At the time it seemed like a good choice because the price was right and the limited specs meant that it would pretty useless for much else. (Focus on your schoolwork, kid!)
The Chromebook ended up getting slightly bent in my son’s backpack, which screwed up the touchpad. Alas, old Chromey ended up forgotten in the ‘pile of old crap I refuse to get rid of’, until one day I decided to do some searching into repairing the touchpad, which I was able to accomplish by ‘shimming’ out to warped case a little bit.
Then Google decided to end support for Chromebooks.
Well, today I dusted the old girl off and began with the question: can one install Linux on this thing?
Turns out, the answer is ‘probably’.
Hell yeah, let’s dig in!

In my free time over the coming weeks and months, I’ll be working on a new version of my pentest dropboxes for IT and OT, and I’ll be turning the projects “Lemon” and “Motion”, which are still on paper, into reality.
And since people keep asking, I don’t have a sponsor and pay for everything out of my own pocket because that’s the only way I can stay creative and independent.
