I want to know how to disable my boot up "thunder bolt" sound. I did some googling and alot of people say to rename
/system/media/FinalThunder.mp3 to something else, problem is... I cannot find this file on my phone. I am rooted, and searched everything on the phone for that filename but nada. Its not in the /system/media folder (in fact there are no files there except for 3 sub folders).

Ideas where this sound is coming from?
