Unlocking a T650i

Hi,

Im trying to unlock a T650i. Im using T650_R7AA024_FS_EUROPE_1_RED52.fbn and T650_R7AA024_MAIN_GENERIC_SN_RED52.mbn for the flashing part and generated a .vpk. I´ve tried to do it with Setool2litle and Far Manager + JDFlasher. If flash the phone without patch everything works fine but it says "insert correct sim". But if I try to flash the .vpk the phone says "Configuration error. Please contact..blahblah". Do anyone know what I´m doing wrong?
