Flash W890i with APAC ANZ firmware

Hi,

I'd like to get simplified Chinese language support on my W890i.

I learned that the W890 uses the A2 platform and DB3159 C900 chipset.
W890_R1EA033_FS_APAC-ANZ_RED52.fbn seems to be the right file for me.
Is that correct?
I understand the W890 and APAC-AMZ part, but not the rest of the filename.

I tried to flash using Omnius_for_SE_v0.19 (A2upload is blocked by my virus scan).
Omnius is asking for
- main fw file
- raw fs file
- customization file

W890_R1EA033_FS_APAC-ANZ_RED52.fbn is accepted as a rwas fw file.

What doe I use for the other files?
I want to use the phone in China.
I tried as generic firmware:
W890_R1EA033_MAIN_GENERIC_AK_RED52.mbn and the customization file W890i_1205-1090_R2A_Customized_Hong_Kong.zip

Those files seem to be the best match. I couldnt find a generic firmware file that seem more suitable.
Do I have to applied the customization or can I leave that out?

I tried falshing with Omnius using the 3 files mentioned above, but I am getting an error:
