If you want to add more languages to your system without changing ROMs, you can try and install morelocale2 from the Play Store. However beginning with Android 4.2, the configuration process of that app is hit and miss.
You need to understand, however, that firmware
has absolutely nothing to do with system languages. It is truly incredible to me how many people have no clue the difference between firmware and software. People that don't know this fundamental difference should not be hacking their devices.
