Samsung Chromebook 303c

[DonkiDroid]

I've been working every day for a few hours a day after work, in an effort to get past the demand for Username and password in Crosh/Terminal. I've tried everything I can find. Shell doesn't get me anywhere. "Root" and "root" in every way possible, does't work. The password I set up in "enable bugging" getting into developer mode doesn't work. My google credentials doesn't work. I've powerwashed...I'm at a loss. Is there a way to completely wipe the os and start with a live usb and clean slate? Anything would be grately appreciated. I've been working on this for a month.
I bought the chromebook from Amazon, it was "refurbished" and not even put back together right...the camera, touchscreen and track pad don't work. But I wanted to start the "rebuild" with a Kali linux distro - or anything that will get me closer to an os I can actually use to accomplish something. Now, its a matter of intense frustration and curiosity that drives me to gain absolute control of my chromebook and make it do what I want it to do - not what crosh/terminal limits me to.
I'm new to this field but am a very quick study if pointed in the right direction.
Thank you.

If you're still interested, sudo chromeos-setdevpasswd
may fix the password issue.
