Hey Trip, I found something interesting. It might help you track down the capacitive button lighting issue.
Soon after flashing 012, I flashed the GApps package right away, so that when I booted up for the first time, I got the whole Google experience (google account) shenanigan.
And the capacitive buttons were lit up the entire time the Google sign intro screen was there.
Don't know if this would be of any help. Just thought I'd report. Can anyone else confirm?
