open up the phone settings then go to sound, make sure it's not in silent mode. If that is not the problem open root explorer, go to /system then /etc scroll down till you see the PowerOn_standard.snd file make sure there isn't a .wav after it.Tried to re flash and got the same results. Used root explorer to manually replace the sound file and still nothing. I must have muted a setting somewhere that I can't seem to find now.
. I removed it and haven't had any problems since .
