Sorry, it is NOT a flashable zip as I do not have a custom ROM installed to test it, you'll have to move the files manually.
If you encounter any problems let me know.
I STRONGLY SUGGEST to back up the files before replacing them with the new ones....
This has been tested and working on a I9506 with stock ROM (4.3), but should work on other 4.3 ROMS and maybe also on 4.2 or 4.4. Test and let me know.
* If your phone dies doing this I'm not responsible
** I just edited some config files, the REAL WORK is from CM team.
*** This has been done for my personal use, I'm not looking for fame and/or glory, just sharing in case it is useful to anybody else
