I just recently unlocked my phone and was having a hard time to find related information for my specific model when I was doing research. I believed the blame goes to different S4 model; huge variety of stock&custom firmware; carrier/ location differences; unlock method and various success rate. Therefore, I would like to create a thread and let all user who has unlocked their GS4 to share their experience (in a very brief form) by filling up the following survey. Your accurate information will definitely help future GS4 user who needs their phone unlock.

GS4 Model: e.g. i9505

"Original" Baseband: Type *#1234# to find, put the last 3 letters/#s here. Example: I337MVLUFNC1, only NC1 here. (Rooted?)
