Need resurrecting from badly developed audio mod

I need help!
Can anybody share/upload unmodified system files(below) from latest update?

# Firmware version 18.3.1.C.1.17 [KK]

# Files what I need...

1. system/etc/...
* mixer_paths.xml(if any)
* mixer_pathsVY52.xml
* mixer_pathsVY55.xml
* mixer_pathsVY58.xml
2. system/lib/...
* "soundfx" folder
3. system/vendor/etc/...
* audio_effects.conf

I installed mod (Dolby 100% boost...)
But it's bad-bad-bad!!!
Also...i made backup, but somehow the backup was gone :(
And... I don't have any chance to get PC :-/
Thanks if you going to help me :)
