how to add a language to k770?

hi

how can i add a language to my phone?

i had a locked version, i used a generic version to unlock, but now i lost all the languages inside, i have nothing but english.
am i supposed to flash FS again after unlocking with setool (with quick access patch)?
moreover, how can i get the language to change in the menus too?

the phone is k770 cid52

thank you

After flashing MAIN and FS, GENERIC main and whatever EUROPE FS the language on the phone will be English and your mean to add the whatever Europe custom pack for the rest of the languages.
