Worked!
Report:
Work on Kamarush MiniCMSandwich Lite AOSP which don't have any equalizer on stock music app.
Only SRS Panel, Sound Enhancement doesn't work, force close everytime I click sound effect on the music.apk that include in the ROM, it may because I delete/didn't use SemcMusic.apk before flash it. I don't know.
But it work great on the music player that include in the ROM (music.apk), I now feel Bass clearer and deeper without reducing the treble which in many equalizer like in PowerAmp or PlayerPro does.
I don't see any difference on Dolby On/Off.
Tested on WT19i + Sennheiser HD202
Thank you so much for this app, I don't need to use another player anymore
EDIT:
I just noticed, Video camera didn't work after flashing Beats, its just freeze when I click the record button. Taking picture works fine.
