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... )

    i337m: How to sim unlock, install TWRP, and root a stock ROM

    Download the stock Fido 4.4.2 from: http://www.sammobile.com/firmwares/download/36977/I337MVLUFNI2_I337MOYAFNI2_FMC/

    Download stock Fido 5.01 from here: http://www.sammobile.com/firmwares/download/54721/I337MVLUGOH1_I337MOYAGOH1_FMC/

    Download Odin 3.07 from here: http://forum.xda-developers.com/attachment.php?attachmentid=1168421

    Download Odin 3.10.7 from here: http://odindownloadxda.com/

    Link to i337m 4.2.2 modem file: http://forum.xda-developers.com/showpost.php?p=63003693&postcount=75

    Link to supersu.zip: https://download.chainfire.eu/696/SuperSU/

    The first two files may take a while to download but it is a good idea to have a copy of these files for future use. The firmware files are in a zip format and they should be unzipped only once to produce a tar.md5 file.

    Note this will trip the Knox counter from 0 to 1 and void your warranty.

    Before flashing, make sure you backup all important files BEFORE flashing anything.

    Flash stock 4.4.2 as follows:
    1. Open Odin 3.07, uncheck everything except f.reset time;
    2. click on PDA in Odin and browse to the tar.md5 file for stock 4.4.2;
    3. put the phone into download mode and connect it to the computer via USB cable (I recommend using the USB cable that came with the phone and a USB 2.0 port, not a USB 3.0 port);
    4. flash the firmware;
    5. when you see the word "reset" in the status window, remove the USB cable from the phone, remove the battery, wait 5 seconds, replace the battery; and
    6. use the home, volume up, power button combination to boot into recovery, wipe data, wipe cache, reboot.
    The phone should now be running a stock 4.4.2 ROM.

    How to install TWRP and root the phone:
    1. copy supersu.zip and regionlockaway.apk files to the phone's internal memory or a micro sd card (the micro sd card should be in the phone before after powering up the phone with the 4.2.2 modem);
    2. power off the phone;
    3. Open Odin 3.07, uncheck everything except f.reset time;
    4. click on PDA in Odin and browse to the tar file for TWRP;
    5. put the phone into download mode and connect it to the computer via USB cable (I recommend using the USB cable that came with the phone and a USB 2.0 port, not a USB 3.0 port);
    6. flash TWRP;
    7. when you see the word "reset" in the status window, remove the USB cable from the phone, remove the battery, wait 5 seconds, replace the battery; and
    8. use the home, volume up, power button combination to boot into recovery which should now be TWRP;
    9. flash supersu.zip from twrp;
    10. reboot the phone and allow supersu to update and disable knox;
    11. go into the phone's security settings and enable the installation of apk files from unknown sources;
    12. power off the phone.

    How to flash the 4.2.2 modem and sim unlock the phone:
    1. power off the phone;
    2. Open Odin 3.10.7, uncheck everything except auto reboot and f.reset time;
    3. click on CP in Odin and browse to the modem.bin file (changing the file name may cause Odin to fail, thanks to @droiduzr2 for this hint);
    4. put the phone into download mode and connect it to the computer via USB cable (I recommend using the USB cable that came with the phone and a USB 2.0 port, not a USB 3.0 port);
    5. flash the modem;
    6. when the phone is booted, locate the regionlockaway.apk file, install and run it (this will remove the sim lock);
    7. power off the phone.

    Before flashing back to stock 5.01, power off the phone, insert a sim card that was not issued by the carrier to whom the phone was locked, and power up the phone. If you see a prompt for a network unlock code, the phone is still sim locked. If the phone does not ask for the network unlock code, the phone should be permanently sim unlocked.

    How to flash back to 5.01:
    1. Open Odin 3.07, uncheck everything except f.reset time;
    2. click on PDA in Odin and browse to the tar.md5 file for stock 5.01;
    3. put the phone into download mode and connect it to the computer via USB cable (I recommend using the USB cable that came with the phone and a USB 2.0 port, not a USB 3.0 port);
    4. flash the firmware;
    5. when you see the word "reset" in the status window, remove the USB cable from the phone, remove the battery, wait 5 seconds, replace the battery; and
    6. use the home, volume up, power button combination to boot into recovery, wipe data, wipe cache, reboot.
    The phone should now be running a stock 5.01 ROM.

    Don't be so pessimistic, check out his thread: http://forum.xda-developers.com/showthread.php?p=42955834#post42955834. There are solutions.

    confirmed fix when codes arent working. it literally fetches the code or something it was the most legit thing ive seen.buy for 15$ plug in and run the program and in 30s ur phone is unlocked....couldnt be any easier.

    thats so much for the heads up
