[AT&T Samsung Galaxy S 4 General] HORiZUN:
May be a stupid question, but please hear me out. I have an SGH-M919 sim unlocked running on the at&t network. Currently using the NK2 modem. If I flash a modem for the SGH-I337, since I'm on the at&t network 100% of the time, would it be beneficial, or would it be bad since it's not my phone?
[AT&T Samsung Galaxy S 4 General] RockRatt:
It shouldn't flash, and if it did it probably would give your a NO EMEI so that would not be good. Modems are designed for ONLY the phone they are made for basically anymore. As to why we cannot flash a "i337m" modem and give versa.
[AT&T Samsung Galaxy S 4 General] HORiZUN:
Thanks for the information. I have noticed I started getting random cellular network drops throughout the day on the latest modem for the SGH-M919 while running 5.0 GPE. Thought it may be the modem, but after your post I think it's due to the kitkat modem being used on the lollipop rom as it has not been officially updated yet.

Have you checked the APN and confirmed that it is correct?
[AT&T Samsung Galaxy S 4 General] HORiZUN:
Yes, I receive 2G, 3G, HSPA, HSPA+ and LTE signals on the AT&T network using my T-Mobile device, but sometimes the network signal just drops completely and says no signal. It reconnects in a few minutes, but it's a bit annoying.
[AT&T Samsung Galaxy S 4 General] jd1639:
Sounds like a carrier issue. Not the phone
[AT&T Samsung Galaxy S 4 General] HORiZUN:
But it only started upon my transition to the 5.0 roms. Cm12 and GPE both have the same results.
[AT&T Samsung Galaxy S 4 General] RockRatt:
I haven't used CM in a LONG TIME but I remember with my S1 and or S2 that when NEW firmware bases came out they would have issues like this. Sometimes I would have to reboot to get signal back, sometimes it was just CM had to fix things so it would work correctly. There were other issues like WiFi or Bluetooth not working at all or correctly with new firmware bases. It always took many updates and months to work out some of the bugs.

My S4 was my first device I never tried out a aosp based ROM like I did on my S1, S2, and S3. I went permanantely to TW based on my S2 with Shomans Roms and permanent TW Roms on my S3 with Enewman and Sk8bordie's Roms because they added a lot of the features I liked from CM and still being TW everything else worked flawlessly.

I would say just give it time for these thongs to work out the kinks, and/or flash back and forth between CM and TW depending on what you need from your phone.
[AT&T Samsung Galaxy S 4 General] skipdawg02:
I have been having the same issue of random signal loss. I'm using att s4 on att. Never had this issue prior to flashing lollipop rom so I'm assuming it must be something with the rom?

Anyone with 337M (Canadian one) flashed with latest base band?
[AT&T Samsung Galaxy S 4 General] RockRatt:
I can give you a link to my MF3 flashable zip if you want to try it out. I don't have safestrap so I do not know how it all works. But I can flash back to whatever modem (mdb/MDL/mf3/mj6) back and forth with no issues. So if you want to try shoot me a PM.

Lime stated above, unless this is a Safestrap issues, I can flash back and forth no problem.

Shoot me a PM if you want to try MF3 modem.

Issues Flashing

I'm having a lot issues flashing this modem on my phone. I tried different recoveries but nothing have worked for me, what other options do I have to install this modem?
[AT&T Samsung Galaxy S 4 General] RockRatt:
What ROM/firmware are you using?

Is your phone safestrapped?

Do you have twrp? Or cwm?

And just to BE SURE, you have a i337 ATT Variant correct?

Make sure your download was good, on the dev-host site you will see a md5 number listed. Make sure it matches with what you have downloaded.

It has been downloaded over 100+times so far and haven't heard it not work yet and u had some testers flash back and forth. Let me know any info to see if we can find out what us going on

You have a i9505? i337m? If so that is probably why. At least by your screen shot it looks that way

[AT&T Samsung Galaxy S 4 General] jazenf:
My phone is really a i337m, but when I flashed the ROM it switched it to i9505..
[AT&T Samsung Galaxy S 4 General] RockRatt:
You would need to use a i337m modem. This one is for only the i337 ATT model

Sent From My Spiderman,Ironman,Red,Dark Blue,Green, GreyedOut BadAss Themed I337
[AT&T Samsung Galaxy S 4 General] hemmie:
This happens when the ROM build.prop has different model name in this case GT-I9505 which refers to international version.

But underneath it is still a I337, go to Download mode and check the model there, long and behold you'd see it is I337.

Wish if there is a way to change that as well.
[AT&T Samsung Galaxy S 4 General] RockRatt:
Look at his baesband he has right now. The ATT variant does NOT have that modem. So his is a i337m and not a i337. So I doubt this will work for him as it is a i337 ATT Modem

[AT&T Samsung Galaxy S 4 General] dirt:
build.prop can be changed with a text editor

ViSiON X II AT&T S4
[AT&T Samsung Galaxy S 4 General] RockRatt:
Let me know HOW you can edit the BASEBAND in the build.prop? The Baseband IS the modem. As far as I know you CANNOT edit it. The only way that changes is when you flash a modem.

Second IF you look at hi screenshot you will see the baseband is i337"M"vluamdj and ATT never had that firmware or baseband.

So back to the point he has a i337m and cannot use the ATT modem.

Yes he can edit the build.prop from the i9505 to i337, to i337m, to whatever he wants it to be. BUT this still will NOT change his baseband from that of a i337m

Please if you know something I don't please enlighten me.

I know he has canadian baseband. thought the previous poster was talki g editing the i9505 part from build.prop, not editing the modem.

ViSiON X II AT&T S4
[AT&T Samsung Galaxy S 4 General] hemmie:
Yes right, I did not notice he has I337m. In this case either it could happen ATT modem would stick and you'd get horribly bad modem fucntionality, OR it would not stick since the basebannd modem is not compatible with his model I337m.

I double checked the ATT MJ6 modem I have it does not have a build.prop so not sure how the model number is changed to I9505, could be due to some flash which contained a build.prop
[AT&T Samsung Galaxy S 4 General] dirt:
build.prop is in the /system folder

Hope you didn't mean flash the latest ATT modems I have listed in the OP? The 1337m cannot flash modems in recovery (unless something has changed) and have to flash modems in Odin or mobile Odin I believe. These modems posted here are only for the ATT Variant
[AT&T Samsung Galaxy S 4 General] spd_rcr:
Looks like this thread is far more up to date than the modem thread in the development section. Thanks RockRatt!

Curious if anyone has experience using the latest NJ4 modem on their i337 with T-Mobile LTE ? (I'm currently on MDL Bootloader, MK2 Baseband/modem, Lollipop ROM)

Thanks
[AT&T Samsung Galaxy S 4 General] geoldr:
Hi all. Just started playing around with my S4 again after having it in storage for a while and using other phones.

I got the phone on release and did the Loki patch to bypass the locked bootloader. I just did the getprop ro.bootloader and I have AMDL. I have flashed a 5.0 ROM with no problem with TWRP . Is there any new baseband I should flash to update it? My baseband is also 1337UCUAMDL.
[AT&T Samsung Galaxy S 4 General] RockRatt:
You can flash any of them in the OP with your twrp/cwm recovery. It is NOT necessary to flash modems, some work better than others for YOUR specific area of the country. I have NOT tried them on a 5.0 based ROM yet. But as long as you keep your MDL bootloaders and custom recovery (I prefer twrp) then you are good to go to try them all out and see which works BEST for YOU, YOUR phone and YOUR AREA. Happy Flashing

The Newest is at the top in the OP, and arranged by dates when they were released
[AT&T Samsung Galaxy S 4 General] geoldr:
Great, thank you! So i see that there was not a modem released to go along with the 5.0. But I assume this is probably because Samsung hasn't release 5.0 TW official yet.

I tested the modems and I really do not properly 4g Peru calls do not work.
[AT&T Samsung Galaxy S 4 General] RockRatt:
Yes, we would need a ATT 5.0 firmware to be able to get a new modem. If there is a LEAK for the ATT 5.0 then it could be pulled from it.
[AT&T Samsung Galaxy S 4 General] celery952:
I am definitely not understanding how to download these files. Im trying to get the latest modem for ucufnj4 and its just sending me through loops of malware installs. What am I missing here?
[AT&T Samsung Galaxy S 4 General] jd1639:
It's the dev host site. It's terrible and very deceptive. There is a download link that'll get you the file but choose carefully from the site. I think it's usually the middle one of three, if I remember correctly. I don't use it any more and recommend no one else does either.
[AT&T Samsung Galaxy S 4 General] celery952:
Ok then I am right in my assumption, as it shows all his files have been removed. Noone has mentioned that in recent pages so I was fairly confused as to if I was doing something wrong. So at this point im at a loss as to where to find a modem file to restore the wifi on my phone after installing the latest echoe rom :P I have been searching myself crosseyed
[AT&T Samsung Galaxy S 4 General] TLK3:
Not sure what you're looking at, but files are there. Click the blue "download now" button. I just tried and it's working fine.
[AT&T Samsung Galaxy S 4 General] celery952:
when you click that, it downloads an exe for me that wants to install a download manager and other malware that gets me nowhere.

That's for the international variant, It most likely would not work. I have tried that on the S2 or S3 (I cannot remember which) and it would flash but not work at all, NO sound on calls. But I do not think I have tried on the S4
[AT&T Samsung Galaxy S 4 General] Kasdarack:
So have you removed all of the modem files from devhost? Downloads fail.
[AT&T Samsung Galaxy S 4 General] RockRatt:
Nope they are still there. I just downloaded from the first link in the OP to verify if it would download for me. Try again and let me know
[AT&T Samsung Galaxy S 4 General] Kasdarack:
It just downloads a tiny file with the right name. Navigating to your profile shows that you only have 2 files on the server, the directories for your modems show 0 files.
[AT&T Samsung Galaxy S 4 General] RockRatt:
I again just clicked on the link in the OP for the top modem link. Chose DOWNLOAD NOW and it downloaded the correct file. The file sizes ARE SMALL about 29k and supposed to be.

MAKE SURE to click on the DOWNLOAD NOW button and not the DOWNLOAD as that seems the site changed something for that file? Blame dev-host for that.
[AT&T Samsung Galaxy S 4 General] Kasdarack:
The zip file is corrupt though. Every time. Both my rar program and TWRP say so.
[AT&T Samsung Galaxy S 4 General] RockRatt:
I will pull my S4 out today and test them. If they work I will note the .md5 of each file so you can make sure it is complete file.

How are you downloading them? PC? on your Phone?
[AT&T Samsung Galaxy S 4 General] RockRatt:
I just downloaded via Dolphin and it appeared to download correctly but when it extracted it was empty.

Then I downloaded via stock browser and extracted it. It had the correct files inside.

Next I compared the .md5 of the downloaded file compared to what dev-host shows the .md5 should be and they matched as seen below.

So try a different browser possibly?

I will also download ALL the files, check the .md5 today, and flash each one on my S4. Will let you know how it goes by tonight sometime.

So, I have a SGH-i337 ATT Galaxy S4 that is now flashed to Stock rom on 4.4.2. The issue is, the WiFi doesn't work. I read somewhere that the modem might be missing, and that I should try flashing the modem. The wifi light goes light green when clicked and then goes back to grey in 15-20 seconds. How should I decide what modem to flash? And how exactly do I flash it? Do i just put it on Odin via the AP button like I did to the ROM?

The phone has a baseband of I337UCUFNB1 and is running 4.4.2.
[AT&T Samsung Galaxy S 4 General] RockRatt:
You just put the zip into your sdcard, reboot to recovery, flash the zip in recovery. No Odin needed
