Worked like a charm.
Worked like a charm from a flash drive Ubuntu 12.10 install.
If you're wondering, all your data is safe, it doesn't reset the phone.
The only issue I had was the SuperSU binary wouldn't update. So I uninstalled it directly from the Play store then re-insatlled from Play. I noticed that SuperSU was updated today. (Feb.23rd).
Thanks you for this!
