Yesterday, I did what you say, but no luck. So I replace service.jar in framework, it does work, led notification (menu softbutton) now blinking, not just stay on when receive notification, and all soft button (back-menu-home) light like a wave when receive missed call. But, I faced a new problem, when I clear whatever in the notification bar my streak freeze, pull out battery to fix. So I decided to go back using default service.jar, and notification led working (just stay on, not blinking) but not bad
