Remove SIM-lock patch generator

[ung]

I want to unlock sim and use thail language on my w580i. I just flash the main firmware "W580_R8BE001_MAIN_ORANGE_LA_RED52.mbn" and firmware "W580_R8BE001_FS_THAI_RED52.fbn". After finishing, I use "SIMLockPatchGen_v2.1" but it doesn't work. Sim is still locked. Coulld you please help me to fix this problem?
Thank you so much.
