Hi guys one of my friends bought a S4 in the US, It's AT&T locked SGH-I337 so can't use it with sim in our country (South Africa)We have two models of S4 here, the I9500&I9505. Was wondering what the right steps is to get the phone working? Must I root the phone and flash custom Rom & kernel or just unlock sim card? I'm not new to Rooting or flashing Roms but haven't fidled with carrier locked phones before. And is it possible to use custom Roms from At&t in other countries thanks in advance [emoji2]

The Sgh-i337 is basically the same as the gt-i9505 EXCEPT for ATT locking the bootloader on that model.
You CAN Sim unlock it so you can insert your Sim into it. You will have to reach it a bit though. It helps if you know what firmware is installed on the phone. If it is MDB, MDL, or MF3 it would be easier to do I believe. Either way look for the threads about unlocking.
If you have NEWER firmware then there are separate threads for it, and it will more than likely need to be rooted, flash a older modem, then perform the Sim unlock from the menu. If you cannot find the correct post I can help look for it later.
Just reply back with WHAT firmware and Baseband you have installed on the phone and we should be able to help you further.
If you do have MDB or MDL firmware do NOF update it...

Thanks for reply ,I have NC1 firmware and I used Method 3 on this guide http://forum.xda-developers.com/showthread.php?t=2595457 .SUCCESS!
Could you recommend a modem I could try other than MF3 as the signal isn't that great ?

Not sure which would work best for your area. You can download and try any/all of them until you find one that works best. You can switch back and forth with no issues without worries

Do not Odin flash the AT&T stock firmware on a Tmobile phone even if it's unlocked.
If you do you will not be able to make or receive any phone calls.
You can flash AT&T or Tmobile CWM/TWRP flashable stock or custom zip file roms because
those do not contain the radio/modem images like the Odin flash firmware do.
If you odin flash back to stock Tmobile firmware you will loose root unless you re-root after flashing.
As far as bootloaders go, a Tmobile phone requires a Tmobile bootloader, but you don't need to worry
about that if you flash the stock official tmobile firmware with Odin.
All the other tmobile and at&t cwm/twrp flashable zip file roms found in these threads don't contain
any bootloaders that's why they can be flashed on any unlocked and rooted tmobile or at&t phones.[/quote]
so the hardware is different is that why you cant flash att stock firmware with odin on a T-Mobile s4

The hardware is NOT the same.
If the hardware was the same for both the AT&T S4 and Tmobile S4 phones then there would only
be one model for both carriers and both carriers would be using the same frequencies of operation.
It's not the software that determines the frequencies of operation, it's in the hardware.
Another thing is that the AT&T has a locked bootloader, the Tmobile bootloader is not locked.
(Whether the bootloader is locked or not it has nothing to do with rooting)
He is correct here...they are not similar. 2 different modems etc.

No you cant. You have stick with att firmware or else your phone will be a brick.
What would be a better phone to get to use on AT&T? An unlocked T-Mobile S4 or an AT&T branded S4?
AT&T ROMS on T-Mobile S4
I've been attempting to install the stock AT&T firmware on my T-Mobile M919. I understand after reading the thread that this is not possible which is why the Odin flash always fails. I am using an AIO (AT&T) sim card. I have been flashing ROMS built for the I337. Most boot loop after install. Those that install successfully cannot activate the WIFI function on the phone. Both Xperia and Darth Stalker work when installed for the AT&T variety of S4. Today I read the Goldeneye installation instructions which state if the AT&T baseband is not flashed on the phone, then WIFI will not work which is the problem I routinely experience. So my question is should I be flashing T-Mobile S4 roms even though I have an AT&T sim? or do I have another issue? The phone is rooted and sim unlocked. Thanks!
I own a i337M S4 is it possible to flash via odin the i337 att firmware? and have the modem and everything still working? So basically I want to take my Canadian S4 and make it usable in the US? I'm going to be moving in a few weeks.
Hi, I have the same question.
I am planning to install Telus rom v 4.2.2 on Fido S4 which is on Android 4.2.2 Baseband i337MVLUAMG1.
I have unlocked (SIM) the phone using unlock code and Rooted using CF auto root.
Have TWRP installed. Have made nandroid back up.
So here are the steps I am going to follow.
1) Download Official Telus Firmware (4.2.2 AMG) from sammobile.
2) Wipe to factory default using TWRP.
3) Flash Telus firmware 4.2.2 using Odin.
4) Root the phone.(CF-Auto Root)
Can someone please tell me if this is OK?
Are there any chances of bricking the device if you install telus rom on fido phone?
Just want to make it sure before I proceed.
I have a galaxy S 4 for Cricket model SCH-R970C. I need to unlock the phone to able to use the SIM slot outside the U.S. I've been able to root the phone and I tried flashing a i9505 ROM thinking that would unlock the use of the SIM with no luck. The baseband modem firmware does not change when I flash a different ROM. There is little to no info out there about the cricket GS4. Is it possible to flash different modem firmware so that the phone can behave as an i9505 model? The hardware is the same... just can't change the modem firmware.
I need this ASAP otherwise I need to find a new phone! I'm not in the US now and calling Cricket is not an option. I tried flashing a different modem firmware using ODIN but it fails. What am I missing?
Any help would be appreciated. I'm willing to "donate" $$ for a solution. Thanks.

Hi,
You should not flash a modem that is not meant for your phone.
You are risking a brick if you try it.
Your best bet may be to just buy an unlock code online.

No, i gave up on the phone. I don't think it's that easy to change the baseband firmware on the phone. I didn't try buying an unlock code, but that might be the only solution for now - just make sure the unlock code is specifically for the cricket model.
Has any managed unlock it? I need older modems in order to complete. The unlocking please provide me with them if you have.
Hi guys,
I read a couple of threads and tried a couple of things and didn't work... Im trying to sim unlock my Galaxy S4 GT I9500 on stock android 4.3 not rooted and is not working.
I read about a code using *#0011# code and didn't work.. Post was not specific about using no sim, original carrier sim or desire carrier sim.. anyway I tried all and was a failure.
I read another thread about flashing a modem and downgrading the firmware but wasnt specific enough about how to do it and the requirements (android version, rooted?, how to do it, etc)
I try one of those "code pages" and even they couldnt help me. My carrier is Movistar in Nicaragua.
Is there is any easy way to SIM unlock my phone? maybe by just installing a pre-rooted, pre-unlocked rom? or is there is a page/guide/video with specific instruction on how to do it?
thanks in advance.
I think the step by step instructions on SIM unlocking in the main thread on the topic are pretty specific. They don't mention downgrading the device modem through Odin however because they were written before Samsung patched the exploits that allowed the SIM unlock to work.
Downgrading the modem to an Android 4.2.2 version in the AP/PDA slot in Odin is necessary to run either unlock metbod. However, you can really mess things up trying to unlock if you aren't careful, especially with the service menu exploit.
Hey people, I have an issue going on here.
I was going to unlock, but decided to reflash firmware and change the csc from rogers over to bell.
Kies recognizes the phone now as being a 'bell' phone, and have done an update just to confirm it but it still will not accept a bell sim. Every time I have inserted a bell sim it requests the 4 digit unlock code. The sim works just fine in my S3 and another bell S4, so that is not the problem.
All settings in the phone also show it to be 'bell', home screen and all, so the csc did take.
All the modems/firmware on sammobile are multi-csc, as i have tried to just flash the modem alone after I extracted it.
I could care less about being truly carrier free, as I am locked into a bell agreement through work.
Any suggestions on this, or do i have to purchase a code? I assume its locked now so I cannot downgrade to my understanding to a lower modem to use the service menu to unlock.
Thanks for the input.
I've flashed from a Bell 4.4.2 to Telus 5.01 without issue and the phone will remain sim-locked. The only difference I have seen between the Bell, Telus, and Rogers ROM are the carrier apps included with each ROM.
The sim unlock code is 8 digits long.
You should be able to downgrade the i337m's 5.01 stock ROM to a i337m 4.4.2 stock ROM. Then install the 4.2.2 modem, root the phone, run region unlock app, re-flash stock 5.01, and the phone will be sim unlocked. Doing this will trip the knox counter to 1 and void any remaining warranty.
I tried to downgrade, but it didnt take. I will try again. I know there was a discussion on booting the phone and not signing into google then reflash again. Is this needed?
Thanks for the reply.
Well, I got it to work this time. Much appreciated
You tried to flash a stock 4.4.2 rom from sammobile.com? Were there errors in Odin?

If you would check some threads there are answers to all of your questions.
1. You can use Odin to flash the 930U firmware on a 930V. The 930U is the unlocked version of the phone that will work on any carrier's network and has no bloatware.
2. The most current update for the 930V is PF2.
3. Google released Android 7 only yesterday so it will not come to Samsung devices for 2 or 3 months at the earliest.

1. A Verizon S7 930V will never be sim locked. No Verizon phone will be sim locked. If paid to have it sim unlocked you were misled. If your phone was sim locked you do not have a Verizon S7.
2. There are a few threads with the information about flashing the 930U firmware. If you cannot find it you did not look very hard. There is a thread a few below this one.
