Is there anyway to add more system languages?

Hello everyone..

I've been trying for 3 days to add Arabic or Persian or other languages to my Samsung galaxy SII Shv-e120k (Korean), after i upgrade it to 4.1.2 which is only English and Korean, but still have only 2 languages as system and as keyboard input, my problem is i need my entire phone to be in another language than English or Korean..

I tried some apps from google store and not all were converted to Arabic or Persian, even my phone is rooted, had to root it just for that and nothing happened or changed

Can anyone help me with that please.?

Thanks A Lot In Advance.
