Lights on HTC Desire Z not working

Dec 4, 2012
I have flashed MIUI 2.11.30 and I really like it! There is a couple of things not working the way it should.

Most important: None of the lights work, not on the menu, home, back and search key. And not on the keyboard when it is slide out....

In settings it says the light should be on, but even when I set that to: always, the keys light stay switched off.

Is there something I can do about this? Especially the menu keys not lighting up is annoying..
