Hi guys,
I was given a phone to use after I broke my own phone, but the problem is that its SIM locked to Vodafone IE.
When I got the phone, it was on 4.3. After following the SIM unlock guides, I kept running into problems because some menu items are missing. Specifically "[3]PERSO SHA256 OFF".
I did some Googling and saw a mention of the fact that the newer modem in 4.3 has these options removed. So this led me to try downgrade the ROM. The first thing I did here was TWRP/root/custom ROM, thinking that there might be some added options in a custom ROM. However, the ROM i Chose (Albe95 LolliROM) uses the hard menu button to display running tasks, so I couldnt perform the steps in the SIM Unlock guide. Then I tried other ROMs and an old CyanogenMod 4.2.2 ROM, but I didnt have any success. After more research, I found that the biggest mistake people make is not downgrading the modem. Now, I thought this wasn't possible once you go above a certain level, eg 4.3.
After more Googling, I found a link to an old modem, but the link gave me a 404!
I spent a lot of time on this, and just want the SIM unlocked, so figured I'd just ask the experts here.
So, can anyone just link me to the correct modem version for 4.2.2 and maybe a ROM that is compatible with the guide I linked earlier?
Once unlocked, I'll flash a new ROM so I'm on Lollipop again.
Thanks.
If the 9505 is like the 337m, the free unlock method only works when running a stock Samsung dialler. CM and aosp ROMs do not use a Samsung dialler so don't bother using a custom rom to try and sim unlock the phone. If you buy an unlock code, you will need to be running a stock Samsung dialler in order to enter the unlock code.

You need to read the last pages of that thread. All you need to do is in there.
1. Be on a stock rom.
2. Downgrade modem.
3. Unlock sim.
4. Upgrade modem.
OK Thanks,
I managed to unlock!
I installed a stock ROM, downgraded modem to XXUAME2, did the unlock steps, and it worked fine.
I've flashed a custom ROM now and updated the modem to the latest so its all good now!
Cheers.

Hello,
I was wondering if I had the latest + most recommended radio/modem installed to my device; and also, where I could "tune in" to keep an eye on newer and better releases.
I noticed a few threads about radios and modems, and none of them even mention this MK6 modem... Also, they all seem to be ATT specific.
Anways, I am currently using "Baseband Version: I337MVLUEMK6"; should I look into changing?
Thanks!
You are running 4.3 with that modem. I think you can unlock your phone using the dial pad with that version. If you upgrade to a newer version then it is fairly locked down for tinkering and Knox enabled. If it works for you keep it. So unlock your phone 1st if need be.
You are about 3 releases behind
sammobile.com
Fido link: sammobile.com/firmwares/database/SGH-I337M/FMC/
Youre obviously pretty new to this. Basically MK6 is just a rom firmare update from the one before it. Every time samsung releases an update like 4.4.3 it changes that number letter thing. So if you pick any rom on the forum and you notice a fewdsyd later yhat person has updated the rom from 4.4.3 to 4.4.4 that number will change. Anyways its not too important. I suggest Goldfinger in the android development (regular development not original). Its a good one to start off with. Make sure during install to chose the correct phone. For example im canadian so I pick l337m otherwise it wont work right. Make sure if you chose a different rom than one designed for l337m that you download and flash a l337m kernal after youve installed and booted up the rom. I mean install and let the new rom boot to the setup screen. Then reboot into twrp and flash the l337m kernel of your choice. If you read through the goldfinger posters thread theres a kernel tool link. Its cool because it has all the kernels in one file. Just make sure u download the l337m version of the kernel tool. I hope that helps....also some roms wont connect your data and youll have to set up your apn yourself. I find sometimes I have to set up my rogers apn manually. Amyways now im probably confusing you lol. The unified section has roms that work on all phones or you can download roms like goldfinger that let you choose the phone youre using. Ok so to answer uour question the modem type just refers to the firmware the rom is built on. Haha

Actually, I'm already unlocked + rooted... And running GoldenEye 41 VJUGNH2 @ Android 4.4.2
In fact, I was getting all kinds of data drops and other basic function fails until i switched from AMG1 (I THINK!) to MK6 via Odin desktop.
At this time, everything is working fine... I just wanted to make sure it was running optimally. And apparently it's not, if I'm using a 4.3 radio/modem with a 4.4.x rom...
And also, when installing a new ROM, I've only ever noticed changes in kernel, build number, android version, and ROM version; never Baseband version.
I guess I'll double check the ROM threads, maybe I just missed a part about them being bundled with new Basebands...
Thanks folks!
/update
I flashed NC1, seemed to be the latest one... Everything OK for now.
Hai frnds..
Last day got a Galaxy S4.. But it is asking for Network Unlock Key
its running Android 4.4.2 Saudi Arabia (KSA) version
1. Unlocking using GalaxSim Unlock not working
2. Also tried unlocking using codes *#0011#. That too failed...
3.RegionLock Away app says unlock sucessful.. but still asking for unlock code.
can anyone one help me to find the solution.. suitable links will be helpful.
Thanks in Advance
You probably need to flash an old 4.2.2 modem and then use the unlock methods. After that reflash the modem you are on.

I just tried that method and it not working.. aftr downgrading the modem the imei is changed.. then tried the unlock methods..
nothing happd.. and after reflashing the orginal modem it asks for unlock key..
Here is a complete list of firmwares for your phone. Download one of the 4.2.2 versions, install it, then try running RegionLock Away. After that, upgrade to the most recent.
Sometimes downgrading the modem is not enough, which is why I recommend flashing the entire ROM.

Just did like u said.. Downgraded to 4.2.2. but when i downgraded the modem the imei is changed to null. I used the same modem of the 4.2.2.
But wen i flashed the newst modem imei is obtained. And the problem is that unlocking methods are still not working.
Can u provide me with some more methods to make it right...
Contact your carrier and ask for an unlock code, or purchase an unlock code. Those are your only other options if the unlock methods don't work for you. If those options don't work, then the device is pemanently locked to the carrier, which will happen if one attempts to randomly enter unlock codes too many times.
I have read a fair amount here, but I'm not getting entirely relevant info and am hoping for some help.
I THINK I have finally found the place for stock roms. sammobile.com???
Now a bit of background.
I bought this phone used a few days ago. When I had a look, it is already rooted, which I'm fine with.
It is running 4.4.2. I'd like to upgrade to 5.0.x. Gotta friend with the same model. That's what he recommends.
I can live with 4.4.2 if I have to, meaning if I can't upgrade.
Since this is new (to me) I can live with losing all user data. Only thing is my wifi password is long and random and a pain to type in, but that is about all I'll suffer.
I had removed some apps using debloater, mostly just to see, but have since restored them. Then tried to update, got the message, which essentially says "you've got a custom rom. No updates for you".
I know the phone is unlocked, but not sure if factory or by unlock code. Does it matter, and if so, how can I tell?
I know the previous owner had a fido sim, and I noticed some bell apps on here. If I've read correctly, that doesn't guarantee this was originally a bell phone. Is there any way I can tell? Right now I have no sim. I can shove in an old speakout sim that is deactivated.
So anyway

I've downloaded ODIN, but not a ROM yet, since I'm not positive who's I should use.
Also, I had gone thru the guide to enable AWS. That seems to work, as it would take the sim at the wind kiosk. I'd like to keep that, but if I have to redo it, that is fine.
I trust it is not a good idea to upgrade to a "stock" 5.0.x by just flashing roms?
Thx for any help.
ok, another question. I just registered at sammobile, but they don't seem to have roms for the S4??? Are they hidden somewhere? Where can I get stock roms, if not there? Thx
Nevermind. You have to type in the device name. It just isn't on the pulldown list.
Another question you might find stupid.
If I update to (for example) the Bell Roms, do I have to have a valid Bell sim in order to do an update?
Well maybe 2 stupid questions.
I still have to use triangle away for flashing back to 4.4.2 don't I? I read somewhere that they (meaning Samsung) expected the count to be > 0 at some point but I don't remember at what version, and I can't seem to find it again.
So what do you guys do? Flash it a couple of times to get the count right?
If the phone is sim unlocked, it should remain permanently unlocked regardless of whether you flash custom or stock ROMs.
The easiest way to get to stock LP would be to flash the stock LP rom via Odin from here: http://www.sammobile.com/firmwares/database/SGH-I337M/
Before the first boot with the LP ROM, the phon should be factoru reset via stock recovery.
Doesn't really matter whether you flash Bell, Rogers, or Telus. The hardware used by all 3 carriers is the same. The only difference would be in the apps that are installed with each stock ROM.

I think I have reflashed properly. I'm downloading the update (probably to 5.0.1??) via phone now, but I noticed after I started that I have the warning triangle. So maybe the update will not install when it is done. I'll know in a couple of hours I guess.
So I should have run triangle away BEFORE the reflash? Or are you no longer supposed to run that? Or is there some android version after which you are no longer supposed to use it?
Thx
Well, phone seems to have updated to 5.0.1, which is what I wanted. With the update, the warning triangle is gone also.
So thanks again for your help. I guess I'll be on to other things here.
Hello!
To begin I would like to apologize for my english and for creating another threat for this issue (I know there are several already existing).
My issue is the following, I got a Samsung galaxy S4 (sgh-I337M) here in my country (Colombia). I payed for it but didnt try to use it with my sim when I got it (which was really dumb). The phone is locked, it is from telcel and I have been trying to unlock it for sometimes. I have followed several procedures that I feel like im able to do, and there were some that were just too complicated for me (im tech savyy but dont have enough knowledge about cellphones).
I have tried several methods using the *#0011# and I even dare to try one that involved flashing the phone (using this rom I337MTCEFNE2) because it said it would be unlocked after it (didnt work).
I would like someone to help me with the process to unlock it (even if its with a link and some help understanding the basic concepts). Im in coombia and would like to use it here in my country.
So far i would also to know if by using a custom or official rom i would be able to unlock my phone, even if its using the rom from my country (that was not the original for the phone). Also looking at the roms available for Movistar )a carrier here in my country) I found that there are only roms for Kitkat, and I would really like to have lolipop... How does it work exactly?
Thanks to anyone who can assist me with this! And again, I apologize for creating another threath, but i already search a lot.

The rom I used to flash it is running on 4.4.2. So I dont download the 2 roms that you put in that post, but the original ones for the cellphone? I think this phone was supposed to be with telcel.

The modem rom is for 4.2.2, is there a way to upgrade my android version after following this procedure?
Sorry if i ask a lot, is just that im not sure about how roms does exactly work and what do they affect the phone.
Thank you very much for the help!
The phone will not work with a stock 4.4.2 rom and a 4.2.2 modem. After running the region unlock app, flash the stock 4.4.2 rom again, factory wipe, and the phone should be sim unlocked.
I would flash the ne2 rom, then root, 4.2.2 modem, run region unlock, then flash the latest 5.01 rom, factory wipe, reboot, and check the phone.

Did you root the phone to run the region unlock ? You can root the same way.
Hi.. I'm in way over my head trying to install a more debloated Rom than the original stock. Unfortunately I didn't succeed very well.
I tried two different ROMS and both of them turned the Sim off and on every second or so. Lots of *pling* noises followed by a message that the Sim card was or wasn't present. It changed so much back and forth that I didn't even get a chance to enter the pin. I belive it is because of some combabillity issues between the rom and baseband/radio version
This lead me to the question: How do I know what rom and baseband would be the most suited for me? I'm living in Denmark (nordic country), but I simply can't figure what rom that is compatible with what baseband.
Boot into Odin mode and verify the model number. Then go to Sammobile.com, download a rom for your country,and install it with Odin.
Did you buy the phone in the country where it is being used?

Sorry if what I'm asking is obvious, but when I install a custom rom, I also need to make sure I install a compatible radio for my area, right?
Sammobile is only stock ROMS, right? And I'm trying to debloat her phone. So when installing a custom rom from this forum and either the reception is bad, it doesn't register Sim card properly or the like.. It might be because I need another baseband than the one that came with the rom right? And what do I need to look for in that regard?
Sorry, but I find it pretty complicated.
I recommend flashing a completely stock ROM, set it up, and make sure everything is working properly. If it doesn't work properly on a stock ROM, it is unlikely it will work properly on a custom ROM.
I find it best to run the latest bootloader and modem regardless of which ROM will be used with the phone.
Problems can sometimes occur when flashing current ROMs over old bootloaders and modems.

Thank you for the already helpful reply.
The thing you say about always flashing newest modem regardless of rom, is very helpful. I didnt even know you could do that. But my problem persist:
I already flashed back to stock, and it runs fine. SO far so good. The problem is that out of 16 GB, the bloatware is justing taking up to much space. But the last two rom I tried both had problems recognising the SIM card (toggled present/not present all the time).
Thats not the case on stock.. So how do I find the proper modem for my phone to use with a custom rom?
I keep seeing a link to sammobile, but all I can find is the bloated stock rom (or I dont know what to look for). Can I grab just the modem somewhere?
When installing a custom rom, it changes the current modem right? AFAIK I have to flash the proper modem afterwards, right?
And therein lies my problem: I dont know how to find the most suited one for my country (which is denmark). And the one that comes with the roms seems to be the wrong ones.
PS: A follow up question: Kernel and baseband/radio/modem is not the same, right? The kernel is not region specific, as the baseband/radio/modem, right?

Custom ROMs can't change your modem, they can't write to those partitions.
In other words, your modem will be the same no matter what. The only way to change it is to flash the appropriate modem files or an actual stock ROM.
SO with the stock rom working now, the modem/rom combination would not be the culprit if something doesnt work afterwards?
What could have been the issue with the sim card connecting and disconnecting every second on the other rom I tried? (Iperium/Imperial something)

What I said is that a custom ROM can't change your modem. But that doesn't mean it can't be affected by your modem.
You may want to read Imperium ROM's install instructions very carefully, cuz I'm pretty sure you missed something important.
Doh.. You might be right.. Ill try flashing the tar files in Odin.
But I just recently got my phone to behave when connecting on Odin.. It also connected back and forth all the time. Putting a USB hub in the middle solved it though (and made it possible to revert to stock). Any idea wht that was about? I reckon either some driver or USB power problem? But Im really fumbling understanding it all, and when it acts up at the same time, even the most simple problems can be hard to see through (because there is always the uncertainty that I misunderstood something basic)..
Just having this conversation helped me understand a lot better how the ROMs and modem is connected (or more precise: How they are not).
And I actually may have had the right baseband all along (Nordic Countries). I will know when I tried flashing the rom again.
Thank you very much
It doesn't matter where you are from, the phone should work with any baseband in any country.
The thing is that some ROMs (like Imperium here) may require a different modem to function properly. In this case, it may require the PG1 modem (listed in the Imperium thread) to solve your problems.
Before flashing a stock ROM, confirm the model # in download mode.
If you want a debloated stock ROM, you could flash a stock ROM, flash TWRP recopvery, flash supersu for root, and use Titanium Backup to freeze or uninstall apps.
So right now I tried flashing the Resurrection Remix ROM, but it wont make any calls (a voice just says that the number cant be reached, even though I know the numbers exist). What could be the case there?
The modem and bootloader may be too old.
can it also be to new?
I have consulted the below site several times, but the link is dead to the page where I can look up what modem to use.
Can someone please point me in the right direction of which to use?
This site: http://forum.xda-developers.com/showthread.php?t=2192025
What modem should I choose for my phone? Living in Denamrk and trying with the ressurection remix rom? I tried 3 different of the modems starting with XX but all have the same problem: I cant make any calls. It just says that "there isnt any members on the selected number".
Making calls works fine on stock rom

The ones linked in the Imperium ROM thread are the newest.
And no, it can't be too new.
It's probably something related to your phone model not being fully supported by the ROM.
JDCTeam ROMs should work, because they support a wide range of S4 models.
I got stock rom to work (again again)
And now I managed to flash the JDC Team you recommended and still having the baseband from the stock rom (Which were able to make calls)
But whatyaknow.. I STILL cant make outgoing calls on the custom roms! What in the world can be the problem? I spent the whole day on this.
.. I should be able to make outgoing calls without flashing Gapps, right?
Yes, you should be able to make calls without gapps.
You flashed the latest stock rom and confirmed everything works?
You confirmed the model number in download mode?
