I downloaded and gunzipped the chromebook image on my chromebook (in dev mode) and used the command in the documentation to try to put the image on a Lexar class 10 micro SD card in a Nexxtech sd adaptor. I used /dev/mmcblk1 as that is the device for sd cards on the chomebook. (making sure any existing partitions are unmounted)

Enter after being in dev mode, open the browser, press Ctrl + Alt + T to get a terminal
Then the commands are:

Code:
sudo su -
cd /home/chronos/user/Downloads
gunzip kali-linux-1.0-armhf-chrome.img.gz
umount /dev/mmcblk1*
dd if=kali-linux-1.0-armhf-chrome.img of=/dev/mmcblk1 bs=512k
After issuing that command, about 4-5 minutes into the write, the chromebook reboots.
I Log back into it and the chrome browser complains it was not closed properly.

So couple questions...
Is this process tested on the chromebook itself?
Is that supposed to happen?
Am I supposed to do it on another linux system?
Anyone having success or similar troubles?
