Wow armond, the EXACT same thing happened to be while running Illusion. I couldn't factory reset in recovery, b/c that led to a bootloop when i pressed "yes". I wiped, cache/dalvik and phone worked for a little, had a hot reboot, and bootlooped again. By any chance are you running Ktoonsez kt747 kernel? And i eventually got it fixed thanks to Doc through ODIN. Best of luck!
