Which Firmware to use on C905?

Just recently got a C905 and I want to debrand it.

SEUS just kept telling me that my firmware was up to date no matter what customize_upgrade.xml I used on it, so I decided to go with flashing it instead using A2Uploader.

I downloaded C905_R1BA034_MAIN_GENERIC_SE_RED53.mbn and flashed it to the phone but it didn't seem to do anything. :confused:

Not really sure which I need to use for it or even if I'm doing the right thing.

Help?

Use these files and A2uploader CID53:

C905_R1EA033_MAIN_GENERIC_SI_RED53
C905_R1EA033_FS_WESTERN-EUROPE_RED53
C905_1209-4774_R6A_GENERIC_WESTERN-EUROPE
