hi there
if your language isn't supported by your firmware, you have to upload an other PPM-package to it, wherein the language specific information is.
for this operation you have to use flasher cables and after it a mbus cable for updating FAID.
you can get the firmware from http://brad.satelit.cz/8210/
look there in the specific pdf file to choose the correct language pack for your needs.
backup your EEPROM area (as far as I remember the start adress is 0x003D0000 for nsm-3) and flash the choosen image to your mobile.
after this you have to upgrade FAID.
all this can be done simply with an outstanding open source flasher, knok
