K510i modding issue with acoustic settings

So, I, after registering here and reading some info, did mods to my SE K510i:

1. Red Carpet Menu (originaly for W800) installation in my phone
2. UT3 Themes Start up/Shutdown image and mp3 installation in my phone
3. Accoustic settings installation for mu phone, BUT -

- After installing any AcuMax v6, HOT Acoustics and some other pack I found that my front speaker is become unusable / not working. All sound during call has been transported to back speaker. Turn On Speaker function works as normal ...

The worst is that after trying to revert beck to original acoustics, the same issue still appears to occur. Only thing that works is full reflash with SEUS.

Where is the error? Is it my modified menu.ml causing this bug?

All files used to mod my phone should be possible to find in Menu Icons SubForums topic created be me.
