Root and use region lock away app.
If that doesnt work, you can use safestrap to flash MDL modem and try the code method.

Unlocking help needed

Hi all first of all the phone is locked to EE I tried the *#0011# method and at first I couldn't get into the right menu which I've found out to be the modem that is installed needs to be me2 or older.
So I have flashed the me2 modem and was able to get the menu to turn the lock off but I can't get to the next menu to save the setting ?
So do I need to flash an older firmware version to match the older modem? To get the menu to appear?
I'm thinking to flash a o2 stock firmware to see if that works?
Thanks for any advice

Hello, I currently have a AT&T S4 i337 unlocked by the *#0011# method to work with Claro. I want to flash a custom rom in it but im not sure if the method is gonna stay or if I have to do it again or so.
Does that unoock method unlocks forever the device even if I flash a cutom rom, recovery or kernel???

I'm sure you can carrier unlock your S4 and allow you to use another Sim card. Try searching for it

I think you can carrier unlock for 3G data only. But I think Sprint has to give you the code, and you have to be off contract or paid up on your phone.
If you look around you will see the domestic unlock only rolls when you are on mf9 bootloader and can go back to mdc If you are on 4.4.2 the best you can do is foreign unlock after 90 days on Sprint and then they will unlock it.

You can use build prop or you can use MSL app from playstore.

Build prop? And msl app? Whos the vendor who developed the msl app thru the play store? Does the device need to be rooted? And you confirm It works on 4.4.2?
Can you link something for build prop please?
Yes this works. Just tried it on 4.4.2

it worked! ty
Easiest way I've found to get it, is to do a device swap on sprint.com if you have a spare device. It will give you the msl.

[Q] {UCUFNB1} Would Odin work to flash?

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.

You can not flash a custom recovery. The bootloader is locked. If you want to flash custom roms look in the general forum. Look for " index all things mk2 nb1"

Start here and read it all about 6 times. Rooting and putting a rom on the i337 with mk2 or nb1 is not for the faint of heart. http://forum.xda-developers.com/showthread.php?p=49562527

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.

Nope. The only way to get a custom ROM would be to use safestrap.

What about the SIM lock? Do I need to get my phone SIM unlocked before flashing a stock ROM?

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.

So that means I can use any SGH-i337 specif roms but not the i9505 ones, right?
sort of
