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.


Your device will now go through a series of “conditions”, where it will first freeze, then get on a black screen with Blue LED on and both capacitive buttons on, 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 ...

Just did it. Steps came through correctly, waiting for phone to reboot. Gonna need to find a SIM card to test but I'm definitely going to!

Also is there a possibility there might be a way to mess with the bootloader in this menu? This seems new and untested!

It's really that easy?

No option 6 under step 7, so it is not working for ATT S4
Oh it definitely works. I found the thread yesterday in the T-Mobile forums. Not sure why the OP didn't just link to that, which has clearer instructions that are easier to follow.

Mine already had SHA256_ENABLED_FLAG[0] but I went through the motions (it stayed at SHA256_ENABLED_FLAG[0] after the next couple of steps) and did the NV REBUILD.

You can get a T-Mobile SIM at Wal-Mart or any T-Mobile store, just FYI.

ATT phone here.

I've done this, with a few minor diffrences. I had to use the *#9090# code, menu back 3x, then press 1 to get into the unlocked service menu. From there everthing went as described.

Now after reboot, if i go back, it's set to 1 again. There is no longer a gold backup as their was before. Am I unlocked or not? How can I tell ( i don't have another sim handy at the moment... )
