[MOD] Turn off Power on/off sound
I haven't seen this in our T Mobile Forum so I thought I would share.
I hate the horrid boot sounds of our device, so here is how to turn it off.
MUST HAVE ROOT ACCESS.
1. Download Root Explorer or another File Manager of your choice. (Personally I use Root Explorer because it automatically sets permissions.)
2. Navigate to System > Media > Audio > UI, to find "Poweron.ogg" and "Poweroff.ogg". (As you can probably tell, one is the power on sound and the other is the power off sound.)
3. If you don't want it at all, you can simply delete the 2 sound files, but if you might need them later, I suggest you copy them to a different spot in your storage before deleting.
Hope this helps
