Sim unlock question topic

I have a galaxy s4 that i am trying to unlock. I get to the network lock screen where i should have 3 choices being 1, perso sha256 info 2, perso sha256 on
and 3, perso sha 256 off i only have perso sha256 info. When i hit that perso info line i get sha256_enable_flag{1}.
Can someone please give me a hand . Thanks
