flash back to original

Hi all, good evening to all.
Need to fix my issue as soon as possible because need to unlock the phone and use it out of country. My AT&T Galaxy S4 (SGH i337) on Android Verion 4.2.2, Baseband Verison i337 ucuamf3, Build # JDQ39.i337 ucuamf3, Kernel Version i337 ucuamf3.
Spoke to AT&T customer service for few times regarding on the unlock code for the phone, confirmed i have the correct unlock code for the phone,and am had tried 6 times by using the same code was provided by AT&T, unfortunately every time i tried keep saying invalid number.
The phone was flashed one time by myself but can't remember which method i used but was found in this site somewhere.
Today went to AT&T store, a very nice sale person told me because the phone was unable to get unlock because it was flashed, he can tell when the phone reboot itself it has a "unlock lock simple" and "custom" word on the screen. He told me the only way to have the phone unlock is have the phone flash back to original by using ODIN 3.0.7 and ODIN Flash of MF3.
Can anyone please tell me above is right programs to have my Galaxy S4 flash back to original? If they are the right programs, where i can get them and step by step instructions to flash my phone.
Need help badly, thanks in advance

You need to know way more information than can be posted in a single reply. The best thing for you to do is read the "pinned" threads in the general and Q & A sections. Those threads will provide you with the information you need to know about your phone and answer the questions you have. If you try to rush things, you will end up with an unusable phone. Good luck.

[Q] Network unlocking my I9500 and knox

rodtakular said:
Hi guys, I wonder if I can get some help unlocking my I9500. I'm traveling to US next week and would be acquiring a t-mobile or at&t prepaid sim to use the the phone, so I need to unlock it.
First of all, I have verified that my phone is locked to accept sims only from my carrier.
Second, yes, I have tried the methods explained http://forum.xda-developers.com/showthread.php?t=2282683 , but I always get:
MENU NOT EXIST
PRESS BACK KEY
Current Command is 111
If relevant, my s4 is using android 4.3(official from my carrier), the baseband is I9500BUEMK1, build number JSS15J.I9500UBUEMK1.
I don't want you any method that may void my warranty or alters the knox flag.
Are there others "not invasive" methods to network unlock my 9500?
If I have to get a network unlock code from some site in the internet, which ones do you recommend that are reliable? would using a unlock code alter my knox flag?
Thank you so much in advance.

Galaxy S4 i337m Telcel unable to SIM unlock via Service Menu

Hello guys, I have been going madness today trying to unlock my gf's Telcel Mexico Galaxy S4 i337m.
I initially tried from the stock branded rom but I couldn't pass the first page in *#0011#. So I decided to debrand it using a Samsung stock fw I337MVLUEMK6.
Unfortunately even with the debranded rom I have gotten the same result, unable pass the first page in *#0011# no matter how many times I would hit back, and the option 1 or whatever makes no difference.
At that point I stumbled upon this thread and I decided to give it a shot, however no go with this method either, probably wasn't even the point of my situation.
So at this point my questions are, is there another method beside buying an unlock code to get this phone unlocked? If anyone of you who has had luck unlocking the phone with this method would pass me it's HiddenMenu.apk, would it work if I sideload it onto my gf's S4?
Thanks

Any help??

You have to flash an earlier modem to either let you get to the hidden menu or that will work with an app called RegionLock Away. AFAIK that's the only way to do it. Do a search, some people have asked and figured it out but i have the I337 so it's different for me.

Thank you for the answer.. I had somehow figured that out but I wasn't sure. On to this thread it is stated that they have achieved to successfully unlock their S4's through Hidden Service Menu with the MF3 OTA fw.
At this point my question is, can I go with the modem_CWM_I337UCUAMF3.zip(7/9/2013)(US) baseband found on this thread and flashing it over the stock fw I337MVLUEMK6 ?
As far as I know the modem_CWM_I337UCUAMF3.zip(7/9/2013)(US) baseband is a 4.2.2 while I337MVLUEMK6 is a 4.3 version, so I just want to make sure it won't brick the device.
Apart from that, the two phones should be identical right? Like I said this one is a i337m Telcel one from Mexico, while modem_CWM_I337UCUAMF3.zip(7/9/2013)(US) should be AT&T right?
Thanks

You can't flash that one, but you should be able to flash one of older ones. You are right in that that modem is for the AT&T one, and that means it actually won't work for you. You'll have to flash one that has I337M instead of I337U. Besides that, you should be good.

Thanks for your reply once again.. In fact as you have said I tried the I337U AT&T version and obviously I didn't have any GSM/UMTS signal, so I went with the modem_CWM_I337MUMUAMDL.zip{5/30/2013}(Mexico) and I can finally get into the Services Menu, I can do the whole unlock process listed here, however once the phone reboots the result is the same, S4 doesn't read any different simcard beside the one it is locked on, which is Telcel.
Any idea? Is there a specific baseband version that does this trick on i337m? Additionally, is there a website where I can find all kinds of baseband versions for the i337m?
Thanks

Hi, im from Tijuana i also have that smartPhone and was having the same problem, what i did and it worked for me was to install this firmware
http://www.sammobile.com/firmwares/3/?download=27549
From sammobile it is the Telcel oficial with JB 4.3 then i put my Movistar chip and it work..
Saludos...

Yeah, there's a new firmware from samsung that unlocks phones by default.
I've tested it with that exact same one.

I did a previous downgrade to 4.2 tho.
Using that 4.2 firmware, and the *#0011# code, didn't work for me.
So, I returned to the stock branded 4.3, placed a Movistar SIM, and boom! unlocked.
Didn't work too good because of the ugly 4.3 Telcel branded firmware, but at least it's unlocked.
After that I decided to install Goldeneye ROM, and the phone was carrier locked again.
The developer told me that a proper unlock method would be needed to achieve unlocking.
I managed to make a nandroid backup of Telcel's firmware, and Goldeneye ROM, and:
- inserted SIM different from telcel to the phone, booted into Telcel's firmware a couple of times and got it working
- flashed the Goldeneye ROM and retained the unlocking.
the only thing is:
if you ever place a Telcel SIM, the lock will return.
So far I've managed to keep it working once (2 full weeks) without problems.
Yesterday I tried to do it again, and every once in a while the SIM lock returns.
-------------
In other news, anyone knows how to flash other ROM than Telcel's and that buggy 4.2 I found?
Every single ROM I try to flash through ODIN gives me an error, and won't let me flash.
I've tried all these with no results:
I337MUMUENB1_I337MUUBENC1_TTT.zip
I9505XXUENAA_I9505YXXENA7_PHE.zip <--- thankfully that didn't let me flash, it was for a 9505 ::V
I337MVLUAMG1_I337MOYAAMG1_BMC.zip
I337MVLUEMK6_I337MOYAEMK6_PCM.zip
I337MVLUEMK6_I337MOYAEMK6_SPC.zip

[Q] I can't unlock my S4 AT&T (MK2).

I used this thread (http://forum.xda-developers.com/showthread.php?t=2621279) for update my S4. And now i can't unlockt my S4. Can you give a hand?
I searched for it but did found. It's my third day without my cell.
I can: Root and install Safestrap, with it i dont have problem.
I try, but did not work: - Codes like *#27663368378#, *#0011#, *#197328640#*.
- RegionLockAway
- Change de modem to MF3,MDL.
Model: SGH-I337 (AT&T)
Android Version: 4.3
Baseband version: MK2
I buy this S4 in EUA and now i need use in Brazil. :/

I have an AT&T S4 with MDL baseband that I bought a year ago.
I rooted the phone after I received it.
After the root I tried free sim unlock methods that posted on the net and none of them work for me.
Finally I bought the code (I think it cost around $30 and I had to provide the IMEI number of my phone).
It may or may not answer your question but I just want you to know what did work for me.
