Unlocking W800

Heey everybody,
I have a Sony Ericsson k750i with w800 firmware.
Everything works fine.
I want to unlock my phone, but I get an error in SIMLockPatchGen V.2.1:

welcome to Remove SIM-Lock patch generator v2.1
supported firmwares: DB2000/DB2010/DB2012/DB2020 CID36, CID49, CID50, CID51, CID52

You can drag firmware files here...

Selected firmware: D:\Downloads\SE\Firmware\W800 JerN\MAIN\W800_R1BC002_MAIN_EU_EMEA_RED49.bin
Analyzing firmware...
BABE header integrity check failed! "D:\Downloads\SE\Firmware\W800 JerN\MAIN\W800_R1BC002_MAIN_EU_EMEA_RED49.bin" firmware is probably corrupted!
FINISHED.

How do I solve this problem?

download main from somewhere else

I download the main firmware from different sites, but it won't work!?

what cid do you have?

I have CID49

Anyone a solution?
Must I upgrade CID 49 to CID 52?

You cant upgrade CID49 to CID52 on W800! Your Main firmware is not working!

That firmware is corrupted. Download it from somewhere else. The MD5 checksum for W800_R1BC002_MAIN_EU_EMEA_RED49.bin is:
