C905 - Unlocked - Language change?

Hi all,

I'm fairly new to SE phones, so i have a few questions.
I bought a SE C905 (CID 53) where i unlocked the network with the NCK code.

The language customization is ADRIATIC (I'm in Romania). As i am Dutch, i wonder if i have the possibility to change this firmware somehow so i can set the language to DUTCH.

Although i read that sometimes phones can get relocked after firmware changes, i'm wondering..do i have to be worried about that?

Is it possible? How? :)

Hope you guys can help.

Thanks in advance!

Use these files:

C905_R1FA035_MAIN_GENERIC_SI_RED53
C905_R1FA035_FS_WESTERN-EUROPE_RED53
C905_1209-4774_R6A_GENERIC_WESTERN-EUROPE

Thanks man, and then i assume to use A2 uploader for this?
Sorry :( I'm too new for this :D

yes dude you have to use a2 uploader dont worry just flash it.....

Quick question.What language exactly will that be after flashing since its western-Europe.I guess we can make a selection our selfs.

i see there are three files.Whats the last one for?

Last one is configuration settings of your phone
