I thought I will try the whole thing again and this time it worked . The only thing I did different is that, this time I removed audioFx before flashing the mod. I don't know why but it is working now. Only thing now is, it's not working with playerpro, I have to use another player now.
Thanks for all the support
EDIT: too soon, I don't know why but it stops processing in middle of the song while I am playing with different configurations.
Don't you hate it when that happens?! I am scrapping the Stubborn Device series as I think I've found a better solution thanks to @themoto.
You might want to wipe system and dirty flash your rom so everything is in a pristine state.
Download the attachment below. Install apk as user just like any apk, reboot when prompted after opening, boot to recovery and flash 5.3. :good:
The pleasure is all mine man! Working on compatibility until some new cool stuff pops up! :good:
