Increases volume / sounds SE Vivaz [Acoustic]

Hello there,

So the sound of my Sony Ericsson Vivaz, is very low.

I would like to increase it.

I've heard of "The Acoustic", which allows to tamper with the sound.

I saw several software BamMod ² etc., but they can not walk because of a trick.
"C2zMaker", it shows me "Failed" when I do generators and t.

My téléphonne is flashed / unlocked / debrand via the website: "http://simlock.com" official firmware.

So I would have a solution without having to re hack my téléphonne or another, so I do not "open4all" and "RomPatcher"
Therefore fail due to damn C2Z Patch.


Thank you in advance for helping me,
Sincerely,
