how to add language to w910i ?

[baobe]

Hi, I've been trying to add Chinese (simplified) to my W910i, but so far I'm unsuccessful. I've added the zs.lng file, but not the zs.t9 file because I can't find it. (maybe it doesn't exist?) Anyway, I'm currently have a nordic firmware in my phone. Do I have to flash my phone with some other firmware to get Chinese, or can I just add it to my current?

If I do have to flash it with some other firmware - which one should I get?

Edit: I've now been able to change the language by changing the CDA and updating with SEUS. Chinese works great now! The only downside is that my phone lacks Swedish T9 & menus now, since I used the APAC-ANZ language pack.
