Default [Q] Help finding phone unlock code in bml5 file

Hi I was following the steps in this tutorial to unlock my GT-S5830. I've managed to get the bml5.img and searched for the HEX string mentioned in the article. I got the code 47462791 from the search but it doesn't seem to work unlocking the phone from the original carrier. Can someone else search the file to verify this code is correct? ATM I have rooted my GT-S5830 installed CWM and a Custom ROM do I need to enter the unlock code on original Samsung firmware? hopefully I've attached this file ok. Thanks in advance.
