[Q] Factory Unlock on 4.1.1 and 4.1.2 does NOT work!
Okay I have a Galaxy S3 theT-Mobile version, SGH-T999 and Im trying to unlock it by the Service Mode, (dial *#197328640# then UMTS, Debug Screen, Phone Control, Network Lock, Persho sha256 off) but that option  does not show, either way, I click on option  SHA256_ENABLE_FLAG, then I see "menu does not exist" "press back key" and "current command is 118630", Then I wait 30 seconds, press the menu key and select back, I do it again to be in that Ntwork Lock page again, BUT still that option  does not appear, which is the one that I am suppose to click and wait for a minute to get it unlocked. Yes, I have done my research;
I already downgraded my Android version to 4.1.1 since I had 4.1.2 and still no luck.
I have tried it with a T-Mobile SIM, Simple Mobile SIM and Aio Wireless SIM and still does not work. Can anyone help me please.
