Debranding: Help please (C702)

[M8R-bx3ev01]

Hi guys, I had to re-activate my old C702 and am annoyed by its branding (T-mobile). So far, I managed to flash it with a2uploader and updating it with SEUS - but the damn t-mobile branding is still there.
What did I do wrong?
a2uploader's info gives me this:

ChipID:C900,EMP protocol:0401
 
PHONE STATE: "RETAIL"
FLASH CID: 0052
OTP LOCKED:1 CID:52 PAF:1 IMEI:35438702151173 CERT:RED
 
Model:C702
MAPP CXC article: R3EA031     prg12054407_TMOBILE_NG
MAPP CXC version: R3EA031
Language Package:T-MOB-INT

For my flashing-attempts, I used
C702_R3DA029_MAIN_GENERIC_NG_RED52
C702_R3DA029_FS_WESTERN-EUROPE_RED52

and one of the following
C702_1207-4223_R4A_Customized_Germany.zip
Ning_i_1207-4223_R3A_Customized_Germany.zip
K850i_1201-0077_R11A_GENERIC_WESTERN-EUROPE.zip

Any idea where I did it wrong? Thanks

Use these files:

1. C702_R3DA029_MAIN_GENERIC_NG_RED52
2. C702_R3DA029_FS_WESTERN-EUROPE_RED52
3. K850i_1201-0077_R11A_GENERIC_WESTERN-EUROPE.zip

And make this:

Thank you, this is exactly how I did it before (checked it twice ). I just did it again and skipped the part with SEUS - and suddenly, the t-mobile stuff is finally gone.
Does it come back once I update with SEUS?

SEUS should find a newer version for WESTERN-EUROPE - try.
