¡Do not operate the LED notifications!

I have a droid 4, but I have never been able to make the notification LED works except fastboot mode ; There shines green but not when charging or when notifications arrive work. Also me I tried with lightflow but not in root mode. If someone has a patch or know how to make it work I would appreciate a lot, now I have ROM: CM12.1
