I am a noob here, but i know a little! i have a SGH-I717 and i cannot unlock it, i know i can do it through cellunlocker and sites like that but i wana do it without paying any money!
I've rooted the device thanks to Da_G and installed superuser and busybox, tried the galaxy s unlock app but it doesnt work, it gives an error when trying to save in step 1, so i tried locating the efs folder myself and i did, but i cant find the file nv_data.bin, does that file get created when i insert an at&t sim? i dont have one and i am not in the country now!
please any help with this is appreciated, i am dying to use the device and i cant, my flash counter is at 15 now i think and still i cant reach anything!
