How to Unlock Samsung Galaxy s4 for free with hidden options

After Samsung blocked the hidden service menu unlock for Samsung galaxy s4 I am a bit worried.

but today I found out a new process to unlock for free on 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 Service Mode. 

 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. 

 Your device will now go through a series of “conditions”, 

where it will the first freeze, then get on a black screen with Blue LED 

on and both capacitive buttons, after which it will reboot automatically. 

 The whole cycle might take a couple of minutes, so be patient. 

Once it powers back on, it’s network unlocked, permanently. 

Enjoy Folks ...
