I rooted per the instructions.
The first time I ran the script superSu did not show up and chrome would not allow me to access any advance settings.
I ran it again and this time superSU is in apps, but when I run chrome and go to settings/advanced setting it still does not let me navigate to the right panel, nor will it scroll down to the "Under the hood" option.
I can type "under the hood" in the search box (top left corner) and get the right panel to populate but have no way to get there to set anything.
OK-- I figured it out - you need to use the touch pad to navigate.. the arrow keys do not work in this screen.... Duh!
