Hi, I've been reading a lot of posts and finally got courage to ask if there's a way to do a international unlock on Sprint Samsung Galaxy S4 running stock NG2, i already tried to downgrade to MF9 but couldn't pass in odin.
Any thoughts?

I would really like to know this as well I got caught up in the MF9 boot loop. Fixed that then tried to go MJA MDC MF9 and broke thing horribly. Just trying to get my Sprint Samsung S4 SPH-L720 over to T-mobile or at&t. Someone that could point us in the right direction with getting NG2 unlocked Internationally then domestically

There are other similar threads to search and read on.
Once we got the 4.3 MJA update. There was when out bootloader got locked by knox security from Samsung. We can't downgrade to any firmware by Odin but we can downgrade by ROMs just not the bootloader. You either need to use the firmware you are using to restore or update to a newer firmware.
Side comment. I still don't know why would you buy a specific phone for a carrier and use it for another carrier. Doesn't make sense.

First of all thanks for the thread you provided, it helped me to get my phone unlocked and working on Telcel Mexico Carrier, but i can't make 3g service work, i think i screwed some ServiceMode Settings, is there any way to reset them to default and start over?

You might want to Odin back to stock ng2 and do a factory reset. Also have you change your apns? That could be why you aren't getting 3g.

Hey everyone... so I have a problem and im not sure if anything will work... so I tried the free unlock method but it didnt work...but then my phone updated to the mf3 baseband... and when I got an unlock code it was denied.. I looked it up and its because I tried the free method... anyone know how I can get back onto mf3... would kies emergency recovery fix anything... quick replies would be appreciated since i just flew to england and need my phone
Afaik, if you try the free unlock too many times the phone permanently locks the ability to unlock it. There is no way to get that ability back.
I only tried the free unlock mode once, but now I can't get it to unlock with the unlock code I have. And I know there is a way if you have the old firmware to fix the problem, but I was wondering if Kies emergency restore would revert it back to the old firmware, or using Odin and a sammobile firmware would fix my issues

Don't listen to other forums. Stick to the real deal Xda att s4 section. There is no way to Odin, kies restore, etc to an older firmware if you took the official MF3 update. As to unlock, you can try fastgsm. They charge $15 via remote PC. Many folks used it since using the free unlock method toasted their unlocked via code method.

Hey there, I have a samsung galaxy s4 sgh-i337 locked to at&t.
I bought an unlocking code from an ebay user.
it doesn't unlock my phone, it writes: "unlock request unsuccesful". I tried to use the defreeze code and then again the network code, still nothing.
I was referred to a guide that suppose to show me the "service mode menu", by entering *#0011# . so service mode goes on when i put that number in the dial pad, but then I suppose to do 'menu key'->'back'->'menu key'->'key input'->'1', but after I do that nothing happens, the service mode menu with all the options doesn't pop up, it stays in the same page of the service mode. somewhere down on the ServiceMode page it writes "Service:Limited". what should I do?
Talk with an at&t rep or chat online and indicate that you will be traveling and want to use this phone there and they'll give u a unlock code..

Someone... Help.. please
no Mega genius here that can solve my problem?
same boat here man, this is a new problem since not everyone has 4.3 yet. Att won't even give me the unlock code since they changed eligibility few months ago to "only off contract or fulfilled contract phones." I've read one person saying the eBay unlock code didnt work on 4.3 either. And the only success i've heard is another post here on XDA saying they unlocked 4.3 using the regionlockaway app, but they apparently Odin flashed 4.2.2, did the regionlockaway while the phone had no sound/wifi etc., then Odin flashed 4.3(locked again), then flashed 4.2.2 odin again, regionlockaway'ed, then odin'ed 4.3 again and the unlock stayed. That sounds ridiculous and is not an exact science.
So i'm done with At&t's phone slavery and switching to T-mobile on a nexus till the Xperia Z1 is out. I thought this was the future.

Take your phone to one of the shops which do unlocking using a box. It is possible to do it.

If you have another $20.50 go to Myhoian's website it's unlockcode247.com it'll take about a full day or over 12 hours usually but not longer than that he's never failed to unlock any of my phones.

My carrier said I was qualified to do the unlock. How are these services? Paying that much money on a limb sounds sketchy and most endorsers seem to be part of the sketchiness. Anyone else have experience using the only sites?

If you were on 4.3 already than even Best Buy won't be able to install 4.2.2. I would save my self the hassle and just odin the MK2 tar file from here: http://forum.xda-developers.com/showthread.php?t=2601443 it is the fastest download speed. Then when you go to do the sim unlock, autoprime's thread has a link to an MDC modem only file to flash for the downgrade. You can not downgrade the whole firmware, but you can downgrade just the modem to accomplish the unlock.
Hi,
My current phone Samsung S4 SGHI1337 with software version ending MF3 is not eligible for unlock until the contract expires with AT&T. I was told that this phone with the IMEI number can be unlocked but I have to make sure once it's unlocked, AT&T will still service this unlocked phone.
I don't know what this all means. I need to take this phone with me abroad. I don't want to pay for expensive international roaming with a locked phone.
Also, has anyone used cellunlocker with positive experience?
Thank you.
I have used them, and it worked great on my i337m here in Canada. 25 bucks, got the code a couple hours later, threw it in with a non-Rogers SIM, and boom, it worked. HOWEVER, I am using the i337m from Canada, not the i337 from AT&T, so YMMV./
I unlocked my i337 by flashing the MDL modem file using the instructions for the dial codes then flashing current build modem back worked and did not trip knox
Thanks...but technically challenged.

No, I have not. Not sure how to do that either. I read some of the posts here, but still have not a clear clue. If you could point me to a more step by step post, I'd very much appreciate it. :cyclops::cyclops::cyclops::cyclops:
FYI - my current phone does not have international roaming with AT&T. I have it disabled. Would this matter when it comes to regionlock? Can you region unlock EU Zone? I just want to be able to take the phone with me to Europe and insert the local SIM so that I don't get outrageous charge on international roaming. I do text a lot while abroad.
More Confused Than Ever
I am the OP in this thread. I am more confused than ever.
I just used the code *#12580*369# and found that the RF Cal is 20131114 Date of Manufacture
I then used *#1234# and found out that all the AP,CP,CS ended with MK2. But on the phone box, the S/W version ended in MF3. So I don't know if I have MF3 or MK2 firmware version.
When I use the code *#197328640#. I cannot see the #6 Network Unlock screen. So I guess it's hidden from me.
Sorry for all these questions. I am a newbie at this.

Looks like you have mk2 firmware. Your phone came with mf3 but you must have taken an ota update to mk2. That's pretty normal.
to use with straight talk, and I just have to bug you all with a few questions.
The basics: I have an active Straight Talk sim card that I want to put in my galaxy S4 that I just purchased (did not know it was Sprint until it was too late). Now, after hours of trying, bricking, unbricking, rooting and getting false hope from the [HOWTO] / [GUIDE] SPH-L720 Domestic SIM Unlock T-Mobile:AT&T:metroPCS:Straighttalk thread (which I assume would be my answer to my problem if not for the fact every attempt at flashing to mf9 bricks my phone because Odin fails everytime), I don't know what to do.
As of right now, my Sprint GS4 has been factory reset to Android V 4.3, baseband version L720VPUEMJA, with the model # SPH-L720. Can I even achieve what I want to do with these parameters and is there anyone out there willing to give me hand?
Thanks for any replies!
First you didn't completely read through the thread, secondly you can't go back so to unlock you need to flash a MDC modem and follow instructions

I mean. I read a lot. I'll be the first to admit I just may not have picked up on something in those 35 pages. Also, i believe I tried to flash my modem through the Odin one-click, but the process would hang when trying to establish the connection. I know the answer is on this forum somewhere, and I can usually follow these type of tech tutorial fairly well, but I'm just stuck. Do you have any specific advice?
If you are on the OTA MJA modem with MJA bootloader with Knox I do not think you can downgrade to any other previous modem without the issues you are describing with bricking and soft bricking.

You wouldn't have a link to that modem file? Maybe I was trying to us the wrong one. I was using "SPH-L720_MDC_Modem.tar.md5", and the program would just stall.
