[HOWTO] Remove/disable boot up startup sound from HTC One
Couldn't find this info for this handset specifically, so thanks to Jayshah's howto for the HTC Desire in this post
(H/T to him!) I found the equivalent location in the HTC One filesystem for the startup sound audio file.
So then, if, like me, you strongly dislike the HTC "Quietly brilliant" boot sound, here's how to disable it entirely:
Handset is rooted
Put your phone into recovery
Get a working adb shell
1. Mount /system
2. change directory to /system/customize/resource
3. rename or delete HTC_Sense5_Boot.mp3
mv HTC_Sense5_Boot.mp3 HTC_Sense5_Boot_mp3.disabled
As noted by Jayshah, you could install Silent Boot from the Play store, but why add something else eating processor cycles when this solution is guaranteed and requires no additional code?
