[Q] How to unlock Galaxy Express i437? - Samsung Galaxy Express SGH-I437 Questions & Answer

Hi,
I have asked this question a few times at various places. Very sorry about that.
I tried to apply Galaxy S3's unlock procedure to the Express i437. The first steps were fine unitl the last one. I couldn't find the option [4]NW Lock NV Data INITIALIZ. I looked at the S4 procedure, the idea is quite similar, the options differs in Express i437. Does anyone what's the last step to complete the unlock?
Thanks a lot!

What os/rom are you using? The codeless unlock trick only worded on the stock ICS roms. The trick was removed from the JB upgrade at att's request. You have to downgrade via CWM to get root.

Have i messed something up?

Hi,
I bought s4 (LTE version) and it was locked, so i followed this guide:
http://forum.xda-developers.com/showthread.php?t=2282683
But for me it didn´t worked, so i bought a code from ebay, and unlocked the phone and it works good now.
My question is:
It feels like i changed alot of settings when i was following the guide (i did everything correctly), and i know i shouldnt be worry. By following that guide, did i change anything that may change/judge performance?
Is there any way to restore everything to stock, or it doesnt matter?
I would be tankfull If anyone could answer my questions please?

[Q] Need help with Sim Unlock

Hi folks,
I am familiar with the i9500 s4 which I own and mess with. However I also acquired the SGH-I337M model which is locked to the rogers network and I'd like to just unlock the sim.
I ended up just purchasing the unlock code for the i9500 from cell unlocker as it was still early days with the S4 and other methods found on xda weren't working..
Can anyone provide me with a known working guide to sim unlocking this model?
Also, will flashing a custom rom - TW or CM based unlock the sim?
Thanks for any input.

This might be what you are looking for:

However, others that will post that might not give you this warning...
Read through the entire thread before you touch anything! There are possible risks with the method and you need to read about them so you can make an informed decision about if you want to try it or not. If you choose to not read the entire thread or take precautions, it's up to you.
Searching through the "general" and Q&A forums for "unlock" should show you others threads that you might want to read as well. Good luck.
Oh, and flashing other ROMs will not sim unlock the phone.
Thanks,
All seems like different variations of what to select in service mode.. I tried similar service mode steps with the i9500 and never got anywhere so just bought the unlock code... Will keep digging..

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.

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
