Good info, but it seems unfortunately I have no way of test to see if the phone itself is unlocked, and there seems to be no visual confirmation.

Can you reverse this procedure?

I tried this fix to unlock my samsumg galaxy S3 but it didn't work after shaftoff, i tried the following step but it didn't give me any option to unlock it. I called T-Mobile and i requested an unlocking code, so it was given to me. i followed their instructions and phone doesn't want to unlock...we verify my IMEI and matches with their database, their code is supposed to be the right one so i don't know if trying the unlocking procedure given on this site would actually affected unlocking the phone with the T-mobile code. Is there any way to reverse what i did to the phone? or a factory reset would help me out.

Thanks your help is very appreciated!

Still not working

I've just finish flashing 4.1.1. on my s3 and entered that debug/hidden menu with enthusiasm hoping it will work as everybody here said. Well, it didn't. Exactly same thing like when I had 4.1.2., the same MENU NOT EXIST lack of options in the network control menu. I repeat, I have the international i9300 s3 taken on contract from Orange in Romania. Could they done something with the phone restricting those options from being available? And I didn't flash the orange romania 4.1.1. software exactly for that reason, I was afraid that Orange would have removed those unlock options from that menu, instead I flashed OXA version 4.1.1.

Can't flash 4.1.1

I've read through the entire thread and it appears that it's essential to be running 4.1.1, but I can't seem to get it flashed to my phone. It is a refurbished AT&T Galaxy S III (SGH-I7474). I've only found one place to download a 4.1.1 ROM (samsung-updates.com). I've downloaded the .zip from there and extrated it to the MD5 that Odin recognizes. It starts the flash process, but fails everytime. I try reverting to stock through Kies, but when it asks for the S/N, it says that what I enter is not correct. The sticker under my battery only lists the IMEI. If I go into system settings, there is a S/N listed, but it doesn't accept that either. I have been running CyanogenMod 11 (Quantum v3.12, Android 4.4.2) without any problems. If anyone can point me to another 4.1.1 stock rom (the one that I got is PCT-I747MUMBLL1-20121221094741) that they know works, or something else that I can try, I would be forever grateful.

A carrier sim is not required to unlock the phone; however, you will need a non-Rogers sim to see if the phone was unlocked.

Are you on stock 4.1.1?

There are instructions for downgrading. If you are on 4.3 with an upgraded bootloader, you will probably brick your phone if you try to downgrade.

If your phone was updated to stock 4.3, downgrading to 4.1.1 would probably brick your phone.

I think you can go back and forth as long as you did not update the bootloader beyond Samsung's official 4.1.2 rom.

So I have a Bell SGH-I377M and when I put that code it takes me directly to the DEBUG SCREEN but there is not option [8] Phone Control.

Is there a way to proceed without that option available and unlock my phone?​
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] fffft:
You have a different phone than the models being discussed here. First, you should try searching to see if there are any threads specific to your phone. I've never heard of the i377m model, did you mean that i337m? Details count when unlocking, any missed steps or typos will keep you from success.

There is considerable overlap between recent Samsung models so the methods here might still apply to your phone. It's just unclear what model you have and you didn't provide crucial details e.g. what OS are you using or exactly what you did see on screen.

All I can suggest is that you read my post again and confirm that you didn't miss any steps. Note any discrepancies to aid in troubleshooting. If you have the 4.3 update be aware that Samsung has moved some menus and there are apparently a number of variants now. I described the common ones, but you may have yet another. Have a look at all of the menus and you may well find that the same or very similar options exist on a different sub menu. Good luck.

Another method

I didn't read all the pages in this thread so I don't know if others have suggested this method. I can verify it works though.

I was on 4.1.2 and it didnt trip flash counter.

I flashed the modem to the one that was in 4.1.1 (With my understanding of things, this should work on any version of Android after 4.1.1. If KNOX doesn't watch the modem this should not have any negative effect on users of 4.3, the modem is usually not tied to bootloader. So with that thinking, you might be able to downgrade modem like I have and unlock.)

Let me know, I might get a 4.3 today to test, either way.

Just change the modem, do the code stuff, reflash modem of choice.

I did this on a MAC.

I went to this thread: http://xdaforums.com/showthread.php?t=1831898

I downloaded the modem from the 4.1.1 (I747UCDLK3)

I extracted them modem.bin

I renamed to NON-HLOS.bin

I followed steps at: http://www.androidrootz.com/2013/06/how-to-unroot-galaxy-s3-on-mac-osx.html

I opened heimdall

"Go into "Utilities" tab and click on "Detect". Click on "Save As..." and name the file to anything your want. Ex. GalaxyS3PitFile. Then click on "Download". "

After the pit was saved...

"Go back to Heimdall Frontend and click on the "Flash" tab. Under the PIT section click on "Browse" and locate and select the PIT file you saved in step 5. "

Once it loaded the file, I clicked Add button.

On my machine it automatically chose Modem. (if not for you, choose Modem in partition details, partition id 1)

Then click Browse.

Choose the modem.bin file you renamed to NON-HLOS.bin earlier

I unchecked both boxes near Start button and clicked Start.

If all goes well it will flash the LK3 modem. It will reboot the phone.

I followed the instructions below, they should match exactly, take your time:

"

Dial the following code on the phone keypad: *#197328640#

Main Menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 OFF

After choosing this option, wait 30 seconds, then go back one step by pressing the Menu button then select back

Now you are in [6] Network Lock then choose [4] NW Lock NV Data INITIALIZE

You should see a message that says

SHA256_ENABLED_FLAG[0]

SHA256_OFF => Not Change

Choose [1] SHA256_ENABLED_FLAG

Wait 30 seconds, then press Menu > Back. Do not use the back key, choose back from the menu popup.

You should now see a message that says

MENU NOT EXIST

PRESS BACK KEY

Current Command is 118640

Note that the exact Command number may vary.. don't worry about that.

Wait another 30 seconds, then press Menu > Back. Do not use the back key, choose back from the menu popup

You should see a message that PERSO_NV_INIT is processing, then PERSO_NV_INIT is SUCCESSFUL

Now return to the SHA256 menu and turn Perso SHA256 back on

Back out of all menus and enjoy your unlocked S3"

Alternately flash modem of your choice now if you dont want to keep the LK3.

The unlock sticks.

Hopefully this will help yall from not having to flash an entire ROM.

Thank you. What is the most painless way to downgrade? I'm not a newbie, but this is my first Samsung. Had apple or many years
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] audit13:
The easiest way would be to do this on a Windows PC. Download Odin 3.07 or newer, get the latest Samsung USB drivers, and grab the 4.1.1 ROM from here: http://www.sammobile.com/firmwares/1/.

Use Odin to flash the ROM but don't check the auto reset. Downgrading will wipe your phone (contacts, data, apps, etc.) and return it to stock 4.1.1. Once the firmware finishes flashing and you see Reset in the progress window, disconnect the USB cable and pull the battery. Boot into recovery, do a factory reset, and boot the phone normally. Unlock the phone, and flash back to 4.1.2 if you want.

I do not recommend upgrading to stock 4.3 as this will introduce Knox and a locked bootloader. There is no need to install the 4.3 bootloader if you want to run 4.4.2 ROMs. The 4.1.2 bootloader will work.

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] audit13:
You need to be on stock 4.1.1. Post 161 suggests that installing the 4.1.1 modem may also give you the menu to unlock.

Was the phone ever running a stock 4.3 bootloader? If it was, you can't downgrade using desktop Odin but you may be able to use mobile odin. If you never had 4.3 on the phone, you could downgrade to 4.1.1 and unlock it using the free method.

Often, a stock rom will not prompt you to enter a network unlock code so reverting to stock would be best.
