As title says it just stopped working after I installed Fcam drivers and app. I tried rebooting but it didnt work. I was running power kernel and i thought that might be the problem so I uninstalled it but still nothing, then i uninstalled Fcam and drivers but LED is not working.

What worries me the most that LED doesnt even light up during startup (when you hold power button) and HealthCheck app crashes

Please help
