I use to use a max mod out before, but it no longer worked after leaving jellybean.
So I made a mod, since most apps don't touch the volume I wanted.
This is a max volume mod.
Just go to ect, and replace the attachment with the file in that folder. Reboot.
Must have root and root Explorer.

If this is to loud, let me know and I'll make other mild mods
