Is there a way to disable the sounds on phone startup and shutdown? When I had JF3 firmware, there were no sounds, but now on JM1 the sounds are there :(
Try Silent Boot from the android market. It automatically mutes your phone when you shutdown.
In this post at Android Central, the suggestion is:
- Open a root explorer, go to
This requires root.
This seems promising, but in my HTC E9 phone (Android 5) these files don't exist :(
