W705 debranding

Hello,

i just get a new W705 by my employer and it's branded with T-Mobile-Firmware. I know how to flash it but i am not sure which firmware-file is the right one. The phone is used in Germany. What are the differences between the files W705_R1DA029_FS_WESTERN-EUROPE_RED52, W705_R1DA029_MAIN_GENERIC_RK_RED52, W705_R1DA034_FS_CENTRAL-EUROPE_RED52 and W705_R1EA033_FS_CENTRAL-EUROPE_RED53?

Before I start to flash an unbranded FW i will make sure to use the right FW. Thanks a lot.


Greetings

Chappi
