Unlocking with carrier provided code - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

My contract just expired so got an unlock code from AT&T, but it doesn't work. According to the instruction email, it won't work on a rooted device.
Does anyone have experience, if I odin to stock, would the unlock code work, and if the phone would stay unlocked if I flash a custom ROM?
Also, could anyone post the files to odin to MDL? The link it the thread that had it no longer works.
Thanks.

You cant unlock with at&t sim!!
You need tmobile sim card to unlock. If you tried already go head back to stock do unlock aim with different carried sim then flash what ever rom you want.
Good luck

Thanks. Luckily I have a Peruvian SIM card, from when I traveled, I used that to trigger the code and failed twice to unlock. I know I only have 5 attempts total so I wanted to make sure to get it right the next time. Did you tried just unrooting on your custom ROM? I'm wondering if that would be enough or going back to stop is required.

Automatic sim unlock

Yesterday when i rooted my phone, flashed Liquidsmooth rc9 and then reseted via triangleaway and flashed a sweden carrier rom and then the poland rom my phone worked with my old operator.
Does root actually remove sim lock?
Root doesnt unlock your phone however there is an app available in the market which allows you to sim unlock if youre rooted.
Google it.. you will find it
Edit: its called galaxsim unlock

[Q] Why is there a CM rom for ATT?

i thought we were still waiting for the verizon model to come out before the unlocked bootloader method to be released. how are we able to have CM for ATT? is it this Loki stuff that is making that possible?
Some people bought their phones off contract and have unlocked bootloaders. Also by using a company for a fee can get you an unlock code.

Sorry for the noob question, but I got my AT&T S4 from Best Buy with my 2 year upgrade contract for $200, and my friend bought his from Best Buy AT&T S4 off the contract except a lot more expensive at $749.99. Is there a difference as I thought they were both i337 models... and all were locked bootloaders...
Not to mention if you use the OUDHS recovery, it's set up to Auto-Loki any ROM which is why it would make a TW-based CM work just fine. That being said, you're going to be dealing with nightlies, so if you're not ready to have a few issues here and there, it's not worth it to you to install it until an official release comes along.

Buying through the major carriers means a subsidized cost. If you're buying off-contract, it means you're the one paying for that subsidization and not the carrier, hence the larger cost. This is exactly why people flock to CL when buying phones off-contract because it's significantly cheaper, It doesn't change anything about the phone's internal hardware, An I337 bought at BB off-contract is still the same physical model as one bought on-contract through an AT&T Store.

I think you're a bit confused. What you're talking about is for a SIM unlock. Completely unrelated to the bootloader unlock we're mentioning here. As of right now, there is no bootloader unlock available for the AT&T/VZW GS4s
oh i thought it came out on the 30th.. so i guess i gotta search around for the unlock method? not sure i understand this "Loki" stuff

Loki is not really an unlock, it's more of a way to circumvent the bootloader since as of right now there's no way to unlock the AT&T variant GS4s. Look at this thread first to download what you'll need for root:
http://forum.xda-developers.com/showthread.php?t=2252248
After that, you can visit this thread here and find what you'll need to use a recovery. Here's one that will Auto-Loki your ROMs for you:
http://forum.xda-developers.com/showthread.php?t=2291956
Or you can run TWRP/CWM and flash this kernel after installing whatever ROM you choose for Loki:
http://forum.xda-developers.com/showthread.php?t=2292341
With these tools installed, you can now run any ROM of your choice, but try to stick to those more closely based to the stock ROM as you can to keep all of your features working.
Hope that helps.

Just keep your eyes on a thread for the GW fix. Should be in the Android Development (not Original) thread. I've skimmed past it several times in the past couple days. And, yes, OUDHS will auto-Loki. TWRP as of right now will not.

Not an unlocked bootloader. Bootloader will be locked if u get the s4 from att. U can install twrp using goo manager then flash a loki'd rom/kernel if you wish. Make sure they are loki'd.

Running mk2 stock want to flash mdc modem for unlocking

I'm trying to domestic unlock my phone but everytime i try to flash the mdc modem using odin, i get FAIL all the time
what am i doing wrong ?
Once on mf9/mk2 you can't flash back/downgrade due to knox bootloader from my understanding. Search forums to be sure.

I'm looking to flash custom Recovery's and what not. I just got the phone 5/2/14. The SGH-I337 on AT&T. Got the phone with 4.4.2 kk. Updated when update was available. Wanted to know if I could use Odin to flash things like any other Samsung phone.

I'm on the same situation, just got my phone from AT&T (SGH-i337) with 4.4.2, now on baseband NC1, I would like to root the phone and it seems the only way is downgrading to NB1 and then downgrade again to MK2.
But I'm not so sure if it's safe to flash the roms having a SIM lock on my phone, is it necessary to unlock it before trying to flash?
Another noob question, a locked bootloader means I can't get CWM, but can I still install custom roms installable through Odin?
Sorry, No custom ROM's for locked bootloaders.

Sim Locking only restricts your phone to a particular carrier, it wouldn't interfere with a custom rom, as long as said rom was built for your carrier.

There really was only a very short window of time to unlock the bootloader. Unless you got an M after the update that was still on the original firmware. Almost right after Rosenberg published, Verizon sent out their exploit patch... I really wish Verizon would stop doing this stuff. It makes no sense.

This will not likely help much unlocking the bootloader, but it is nice of them to do so promptly to allow the few devs who build ROMs to continue updating with the new kernel.

KitKat troubles
I purchased two used Razr M's for use on Straight Talk. After using Radiocomm, the phones worked great. My wife updated to KitKat and lost her service. I used Radiocomm on hers and have it running again. I upgraded mine also and now we both screwed. Modem Fast Dormancy Monitor Service error pops up all the time. I watched mine screen come on like a reboot three times yesterday. Before I went to bed, I noticed that I had no service. A reboot and service came back. I sent two emails to Motorola and have no reply as of yet. KitKat runs great, but now I just may have to buy two more phones. I don't see any help coming and would advise people to stay away from these phone unless using on Verizon. I didn't know all the trouble a locked bootloader and not being able to root would cause. I read that it had been implied that Android slow release stages were to cause people to buy new phones for updates. So I guess the KitKat issues I'm facing are the same. Encourage me to buy before my wife skins me alive!
There is a fix for the Modem Fast Dormancy bug but it requires root in order to edit the build.prop and disable it.
Without root, it is possible there maybe a way to disable those functions by editing the NVM, but it will require some considerable work to isolate the NV Items and parameters responsible.
After editing the build.prop the phone performs pretty well under KK for GSM/WCDMA service.
I will try and take a look at the NV dumps and see what I can find. No promises.
