General :: ViPER4Android Not Working On I9505?

I just did a clean install of omega v5.0 on my galaxy s4 (international version i9505). I've been playing around with the ViPER4Android mod and I've followed the following instructions:

1. Extract and copy ViPER4Android_FX/XHiFi.apk to /system/app/*here*
2. Change apk permission to rw-r-r (644). Reboot.
3. Run FX/XHiFi app from drawer, allow root access.
4. When driver installation prompt, choose Yes to "Install/Update".
5. Choose correct CPU Type. (Refer CPU Driver List)
6. After installation done, Reboot device.
7. If you want use only V4A, follow option1. If you want other existing effects to work, follow option2.
--->>Option1.
-----------8. Choose V4A(either fx or xhifi) in sound settings > music effects (Don't worry, both fx and xhifi will run together.)
-----------9. Make sure in V4A(both fx and xhifi), in menu option, FX Compatible Mode is set to Normal Mode.
-----------10. Download IRS and extract the .irs files to <storage>/ViPER4Android/Kernel/*here*
-----------11. Enjoy.
--->>Option2.
-----------8. Open up both V4A(both fx and xhifi), in menu option, FX Compatible Mode set to Compatible Mode.
-----------9. Download IRS and extract the .irs files to <storage>/ViPER4Android/Kernel/*here*
-----------10. Enjoy.

0. MAKE SURE YOU HAVE CHOSE THE CORRECT DRIVER. Refer OP.
0. MAKE SURE YOU HAVE BUSYBOX INSTALLED
1. Uninstall, reboot. Reinstall, Choose correct driver, reboot.
2. Don't use compatible mode yet, go to sound settings>music effects> and choose v4a(either fx or xhifi). Test.
3. If not working, switch to compatible mode, reboot, go to sound settings>music effects> and select previous effect. Test.
4. If not working, activate safe mode, reboot. Test.
5. If still not working, check

None of the instructions I followed above worked. Also, instead of moving the apk to system/app, I also tried installing as a normal apk and following the rest of the instructions and there has been no sound effect at all.
