Hello All, I was wondering if there was any way to change the DHD's default lock, unlock and low battery sounds. I downloaded a bunch of Crysis 2 sound effects and I'm eager to use them but I have no idea how. I read that I need to replace the lock.ogg and unlock.ogg files under System/media/notifications/ui. However I can't seem to find the System folder when I mount my phone as a disk drive on my PC even when I am viewing hidden folders. Any help is greatly appreciated.
