Unlock samsung s4 exynos 3g i9500
I bought this cell phone SAMSUNG S4 EXYNOS 3G I9500 with register free price but its is network locked.
I paid 2 unlock codes web around but didnīt work.
I need to know a way out of this. I need to know if I wipe data / factore reset and put another room would fix the problem.
I saw that people installed new room and things got messed up... so I am a little affraid of doing this.
I saw that we have to put an oficial room from where it is (MCC MNC) otherwise it wonīt work... so I downloaded one. Then if I wipe data factore reset and install its official room would solve the problem.
I backed up my IMEI (EFS + SYSTEM)... is there any hint about unlocking the phone there?
This cell donīt shows service mode hidden menu...
I live in Brazil.
