yeah that should work. You just have to rename/remove that soundfile then it won't play. Just like the camera/video shutter sounds. I think you have to be rooted, don't know if you can modifiy that from ADB, I've never used ADB
I can't seem to make the command work. I am using android terminal emulator by jack palevich if it makes a difference.
Can you explain where the enter command goes inbetween commands.
I'm a newb to the terminal emus.
