Hi, How do I unlock Samsung Galaxy S4 I9505? Mine is an international version. Android 4.3 XXUEMKE baseband version. I tried the suggestion based on google result which you would do the *#0011# but all it does is it goes to the Service Mode but tapping back or key input 1 does not do anything. Before the update to 4.3 I was able to go to service mode and follow the instruction for *#0011# but after completing it my phone is still sim unlocked.
