[How to] Sim Unlock the Galaxy S4 Without the Hidden Menu

HOW TO SIM UNLOCK THE SGH-M919, no unlock code necessary.
This thread is for all of you that have tried this method and have failed: How to SIM unlock Samsung Galaxy S4 SGH-M919 (tested - works) - Updated: 7/2/13
EDIT: I'm sorry to say that after testing this method out on a replacement s4 running stock 4.3 with the MK2 bootloader, this method DOES NOT WORK ON 4.3 OTA OR MK2 BOOTLOADER
The previous method worked on Samsung devices running the old firmware and was patched by T-Mobile and Samsung in the M919UVUAMDL release. Many new (purchased in the last few months) devices have been known to have this release pre-installed.
This is not my work, it is chainfire's genius. You must, at the very least, go and give him the "Thanks". If you can, donate a beer.
His app "RegionLockAway" was intended to de-regionlock devices that Samsung had marketed as "unlocked" (i9505, N9005, etc).
However, a common side-effect for other carrier-branded variants was that it unlocked their devices as well. I tried it and it worked on my SGH-M919 that I bought from T-Mobile.
TO UNLOCK THE M919,
1. Make sure that you are on the completely stock touchwiz setup that came with the phone (bootloader, kernel, and stock touchwiz rom). You can restore via kies/odin here: http://forum.xda-developers.com/showthread.php?t=2258628. Again, thank the developer if you used it.
2. Install RegionLockAway Thread: http://forum.xda-developers.com/showthread.php?t=2470551
3. Thank the developer, even if it doesn't work.
4. Run the RegionLockAway app and click "Region Unlock"
5. Follow all onscreen instructions carefully.
6. Reboot and test it out with preferably a non-North American SIM. This ensures that not only is it unlocked, but also region unlocked. If it asks you for a code, it failed.
As a standard disclaimer:
If you bricked it, it's your fault. I tried it on my own and it worked for me.
As always, I highly recommend donating to the developers who helped you.

First time first! Thanks for this info. I themed chain fire as well

region unlock and sim unlock aren't the same as far as I know.
You can use sims outside of your region (country) but you can't slap an at&t sim card in there and use it.

No they are not BUT they're closely related that doing one usually result in the other. RegionLockAway will SIM unlock when use correctly. I used it a few months ago to SIM unlock my GS4. After it was done I put in an AT&T SIM and made a few calls plus try a few websites.

Like I said, SIM unlock is usually a side effect of Region-unlocking.

Haha can't argue with you there.
There's some talks about Nolan Ryan joining the Astros in some capacity soon. Hopefully he can get them in the right directions.

Was you rooted when tried the program? I tried it and it said that wasn't able to gain root access and bumped me to homescreen... I am not rooted and on Stock 4.3.3

T-Mo gave me an "Unlock code" and it was from Sammy, and it would not work. After 3 tries, each with a different code, it still would not work, so I gave up.
Today using chainfire's app, it works, and I insert an At&T sim card, and it doesn't ask for the code anymore! it's UNLOCKED, and it recieves a signal and connects to the internet via my wireless router. All's good and after placing my T-Mo sim back in, it's all good!
All the connections still like it used to be.
Awesome!

I just called tmobile they provide me with unlock code.

A little more info would help. "It didn't work for me" doesn't tell us much. Why didn't it work? Any reason given? Firmware, rooted non rooted?

I unlocked my SGH-I337 using a similar method, only I flashed an older modem that has the service menu unlocked. Is that method possible on this phone also?

I had updated to the 4.3 firmware before unlocking and T-Mobile's unlock code didn't work on my phone. This was my only recourse and it worked. Thanks, OP!

You do not need a T-Mobile sim card but the phone must be rooted.

Worked well today, just tried it. Thank you

Is it absolutely necessary to be on stock firmware? I gave it a try running VirginRom and it seems to have worked, but I don't have a sim from another carrier to test with.

[q] n900t at&t

I am looking to use a T-Mobile N3 on AT&T LTE in USA (for unlocked bootloader so I can use custom ROM). Is this possible? Are there any nuances of the phone/connectivity that would not work? Is it as simple as putting my AT&T sim in the phone? Sorry, not too tech savvy. Thanks

I'm using my T-Mobile Note 3 with ATT right now. If I remember correctly I just popped in the SIM and it worked. This is after I set it up with a T-Mobile card, though, and I may have unlocked before using the ATT card.
Now I have it rooted too, everything is fine.
EDIT: sorry I forgot to mention I also changed the APN settings after putting in the ATT card. I think you have to do that too. Bookmonke in his better response below has the link with the info.
NOW FOR A HIJACK:
I want Google Wallet to work, so I think I need to upgrade to KitKat.
Any suggestions as to which ROM to use on this phone that is both KitKat and will work best with ATT?
Also I guess I will have to install TWRP or Clockwork, and thus 'trip Knox' whatever that means. Should I care? I'm not going to return the phone at this point.

Yes, T-moble 900T works great on AT&T, just needs SIM unlocked and the proper APN put in, follow this thread for the best way.

The Knox feature is about security which will no longer operate if tripped. It can also mean the loss of warranty for your device. As for roms check the developer roms to see which one's offer the features you want.

Thank you very much. What is the best way to root the N900T and install a custom recovery? Chainfire seems to only root the device without installing a recovery? Is there a step by step guide on how to do both? Haven't been able to find an all-encompassing one. Thanks

Please correct me if im wrong, but after you use chainfires root you should be able to install TWRP through goomanager from the play store.

I just used Chainfires root and used his region unlock to get rid of the sim lock, then used goo manager from play store to install TWRP.

ISIS, Root and 4.4.2

So ever since I flashed to 4.4.2 I lost my ability to use ISIS, I could always go back to 4.3 but i dont want to.
Is it gonna be possible to use ISIS again now that the S4 has been officially updated to 4.4.2?
And please dont say USE GOOGLE WALLET..
Google wallet doesnt give me cash back, 50% off discounts and such.. so yea.. just dont

Just realized that TMobile published the ISIS wallet app... Downloaded it and got "device is rooted - isis will not run" message.
There appears to be a way around this using xposed framework and an isis root bypass apk. Am trying that now...
http://forum.xda-developers.com/showthread.php?t=2425346
This worked for me but now I'm getting a message that my SIM card requires a Secure Element... I'll stop by a TMobile store and ask them about this later...
Edit - swapped SIM and it works. I don't have a compatible isis card test with but from here I'm sure you'd be good to go

I get install interrupted , Updated failed. Have done a fdr. same result.
Any help would be great.

Is it on the att network? I have a Verizon xperia z2 tablet and it only otas if on the Verizon network, otherwise I get error during DM session, so I had to download the update and flash it

Best buy flashed the latest firmware in about five minutes. Awesome.

Don't install the update. Not missing anything and causes problems. If you have Gear S call forwarding want work anymore.

Can I flash ROMs intended for other note 4 variants?

I'm asking this question because the current build of CM13 for the N910V is underdeveloped at this time and I was wondering if I could flash CM13 for the SM-N910T or the sprint variant without any modem issues, etc.

Do a nandroid using TWRP and try it out. I've been testing different ROMs myself. I don't care for ASOP. Kind of ugly and useless without stock Samsung Apps. But I have tested MIUI, and a few other stock based ROMs found in the international Note 4 forum.

Just backup your EFS, Modem, and Boot partitions for sure. If you get a successful flash, immediately use TWRP to restore those partitions and you should be golden. Might also have to edit build.prop to avoid Play Store issues.

Has anyone tried a Sprint TW rom 6.0.1? I may give it a whirl and see if it works.

Hi there,
I find myself in an unusual(i think?) situation in that I have the verizon Note 4 but i live in Ireland. Now while the phone is sim free for the most part, Data does not work here without a verizon plan obviously and it would have to be a roaming plan so I would'nt even think about purchasing one. So i've been waiting for an opportunity to root my N4, now that there is a method I'm just wondering if I would be able to flash a stock Irl/Uk rom to my phone, or another rom that would allow me to have data and spen features. I would like to find out if this is possible before I attempt to root. My phone is on 5.1.1 and is the BPA1 version. Any help much appreciated, thanks.

Pending you could add the correct APN for whatever carrier you will be using, you should be fine. I purchased 2 of these devices nearly 2 years ago. I'm on Verizon prepaid and my wife has been on T-Mobile every since.
Funny thing is I didn't have to set her APN manually. The phone did it automatically the day I put her SIM in. Now she doesn't get the full potential of LTE speeds and MMS is a bit kwonky, but it works.

Thanks for the reply,
do you mean add the APN settings after i've rooted? I'm intending to flash the vodafone 5.1.1 IRL Stock Rom if it's possible, I already tried adding the APN settings and it does not work(unrooted) due to bootloader being locked and like i said i would need a verizon roaming plan to be able to use data. So if I get root and flash IRL vodafone stock rom, will I still have an unlocked phone or not? I'm not an expert in this but I would assume the phone would then be locked on the vodafone network yes? Or would it remain unlocked to any network? So just to be clear, what i would like to know is 1. will I be able to flash a stock rom from Vodafone Ireland once i'm rooted 2. If I do manage to flash Vodafone stock rom, will the phone still be unlocked or locked to vodafone? Any help much appreciated. Thanks.

Unlocked sim and unlocked bootloader are different. The phone is sim unlocked from the factory and can never be sim relocked (for lack of a better term). So to answer #2, the phone will not be locked to vodafone.
For #1, I seriously doubt you could odin a stock vodafone rom to this phone and even if you could I'd highly discourage it. If the file contained a bootloader, it would lock the bootloader and could potentially brick the phone. I would recommend unlocking the bootloader, flashing TWRP recovery, rooting (or flash a rooted rom), and add your APN's. If the stock rom is blocking you from adding APN's there are hacks to get around it once rooted. I used to use an app called APN Manager that you install as a /system app that would let you change APN's as you wish.

Any Touchwiz rom should support the S Pen. I believe the Paul (5.1.1) rom does. There's a Note 5 rom that should support it. Just stay away from CM13 or any AOSP roms and you should have S Pen support.

Not such an unusual situation hello from Ireland also a proud verizon note 4 user myself. Meteor and Emobile for me. Data works fine. Let me know if ya need any help.

I am also curious about this situation. I got an awesome deal for my 910v; brand new unopened for 280usd. Only problem is T-mobile sim doesn't get service, and it seems people have lost T-mobile service after upgrading to 5.0. So now I'm stuck with my aging S3 and this brilliant phone just sits there. Fingers crossed that johnboy sees some good results T.T
