I bought a locked Samsung S3 (At&t). It is rooted with cyanogenMod 10.2 Android 4.3.1. All i was trying to do is unlock it so i can use it with other carrier. So i bought the unlock codes for 30 bucks but later i found out that the unlock codes only work with Stock rom. I am not an expert at this Root, Custom Rom...stuff, but not idiot either i can follow step by step directions if anyone knows how to make this work. I would like to use the custom rom though, so do i have to recover in stock rom, unlock the phone using the code and than install the custom rom again?
