i637 Jack
 

Unlocked by UST! Just use i617 and read codes ;)

Can u show logs did u unlock that phone personally

I did unlock it personally. That is how I got that method. Just select i617 and read codes. After that insert different sim and turn on phone then enter the code.

Do u think it would work for rocker box i don't have ust pro but both box are similar cause they use the same cables

Why don't you ask that question in the right section?

select i617 use rj-45 e210 cable read code work 100%

tested in i637 from at&t

mate t.y i also unlocked my samsung i637 using your wonderful method

u can use j750 cable as well by selecting i617
