I have just flashed the MAIN.mbn to my W850i, All seems to have went well.

I then tried to create a .vkp file with SIMLockPatchGen to unlock.

Loaded the MAIN.mbn and got this error:

Code:
Selected firmware: E:\Documents and Settings\Administrator\Desktop\W850_R1ED001_MAIN_GENERIC_CY_RED52.mbn

BABE header found and seems ok.

Can anyone suggest how to create a .vkp file to unlock my phone ?
