okay, i did it without far, but i'm not sure if it will work for any other languages other than chinese. Furthermore, my phone can't use chinese for menus.
So first-off, here's what i've accomplish:
Support for Chinese-font display.
First-off read:
how to add languages to your phone - Top Sony Forums
Great guide!
You also have to reflash your whole phone using my method. I can't guarantee that it will work because i JUST started play around with my phone.
this is how i did it.
1) created a "tpa/preset/system/language" in XS++ "files_to_copy" folder
2) added chinese lng files (in your case phantom13, you need to add spanish lng and .t9 files which i believe are sp.lng and sp.t9) in that folder
3) I opened up my cuspack, (hong kong) and edited the customize.xml files in the "tpa/preset/custom" folder
adding the lines according to the guide above.
<allowed-language>zh</allowed-language> ..... etc for the languages you want to add
(on a side-note here, you can also add the suppressing camera command here)
4) reflashed the whole phone with main and fs and finally my edited custpack
Furthermore, i've deleted the lng.dat and lng.lst files using setoolite + delfile script. However, the chinese language was not added and the other languages were also unusable except for english, so i don't recommend deleting it.
On a final note here, i think the problem with my method is the "allowed_language.txt" part. Since i'm not using FAR, i can't edit those files.
