i am using nokia 3660. i dunno what i've installed, think it was philips camcorder (haven't do the crack file yet), seleQ and smsreminder. now my phone can't work! i can't press the menu button, nothing happens when i pressed that. when i press on camera and the others an error "system error" appeared. 
now i can't do anythign to my phone. i tried master reset by pressing *#7370# ( i can press the numbers though) but it's still the same~~
