Use the Hidden Menu .. I unlocked my device first try. Dont use region unlock.
After samsung blocked the hidden service menu unlock for s4 i am bit worried .but today i found out new process to unlock for free in a website

Step 1: Launch the Phone app on your Galaxy S4, and dial in: *#0011#

Step 2: Press the Menu button followed by the Back key. Then, hit the Menu button again and select KEY INPUT. Enter 1 and press the OK button to enter ServiceMode.



Step 3: Press Menu one more time and tap back again. This will pull up the Main Menu for ServiceMode. Tap [1] UMTS.



Step 4: Now select [1]DEBUG SCREEN, followed by [6] PHONE CONTROL.



Step 5: From the next screen, pick [6] NETWORK LOCK.



Step 6: You’ll get three options. Hit the one that says [3] PERSO SHA256 OFF.



Step 7: Now, you need to get back to Main Menu. To do this, hit the Menu button followed by the Back key. In Main Menu, now pick [6]COMMON, and then [6] NV REBUILD.



Step 8: The phone will tell you that a Golden Backup exists. Tap [4] Restore Back-up.

Use the back key in the menu when it says back not the back key on your phone .. Use the MDL modem ..
Private message me and i can help you out .. And possibly call you .. I know its frustrating .. I got it on the first try .. I used a similiar method on my galaxy s2 and its a permanent unloack. Oh yeah after using the hidden menu method to unlock your device did all the steps work properly and did you restore the golden key backup and the phone rebooted automaticcly .?
