VULNERABILITY DETAILS

Not sure if this qualifies or not but I was able to completely remove ChromeOS from the system and replace it with a custom seabios intallation and am now running Core i5 + 8gb ddr3 + I've removed the 16gb ssd and replaced it with a 256GB crucial m4 msata drive. I'm able to run ubuntu linux without issues, though Windows 7 works as well.

 Additionally as far as I can tell I should be able to run an external GPU through the system by making use of the spare mini-pcie slot using a custom made adapter though in practice this hasn't worked yet it does detect the GPU. (Tested with Geforce 750TI)

VERSION
Chrome Version: NA
Operating System: ChromeOS linux kernel 3.4 Previous (Ubuntu LTS 14.04 Current)

REPRODUCTION CASE
Put device into developer mode, run this chruboostu script I made (modified from chrubuntu script) https://github.com/austinksmith/Chruboostu once you're into Ubuntu 12.04. Once inside run this script by johnlewis, I personally used a custom build as my i5 stumpy model is the only one as far as I know that has been exploited this way. His builds officially only support the Celeron version of stumpy.  https://johnlewis.ie/flash_chromebook_rom.sh
