Chrubuntu problem

Okay, I am VERY new to this forum. Anyways, I recently went out and got a Samsung Chromebook (ARM model). Being the linux junky I am, I put Ubuntu on it using these instructions: http://chromeos-cr48.blogspot.com/20...pha-1-now.html

I got everything up and running and was ready to fix the touchpad and keyboard. I found the instructions to do so from this video: http://www.youtube.com/watch?v=bKSeZUzPtog

BUT, while entering these commands in the terminal, I kept getting all these errors (maybe cause I'm a noob) so I closed the terminal and reboot the computer. It booted back into ubuntu but now my keyboard and mouse don't work AT ALL. If I take the chromebook off dev mode, it boots back into chrome.

If anyone has any idea of how to A: get the keyboard and mouse working on ubuntu, or B: somehow making chrome os the default boot without going into dev mode so I can re-enter dev mode and have it boot chrome os instead, so I can open the terminal and re-download ubuntu, that'd be a BIG help.

Again guys, I am very new to this. So you might have to put things in simpler terms for me. Also, sorry if I put the wrong prefix! Thanks guys!!
