I saw that you've added the following to the documentation: "the cros-flash-replace script has to be made executable: # chmod a+x cros-flash-replace. This did *not* help in my case (so maybe not for others also) so I think it should say something else. By the way, the circle around the write-protect screw on the image is white, not red as said in the docs. > > Now I only need to figure out how to install a functional GNU system and > get rid of ChromeOS.
