I never had any issues with my old M919, which is still sitting in a drawer awaiting a new display assembly I cannot afford. It was running CM 10 perfectly and no issues with HSPA or LTE. I was suffering for a while with an HTC Espresso which I could not S-OFF due to HBOOT being incompatible with AlphaRev. Anyway, I ended up with my old roomate's M919 about a week ago and have had nothing but issues getting mobile data to work properly.
It already had the MK2 Baseband installed-though I did not bother to check if it worked on the stock 4.3 ROM he had already installed. Nor did he ever say anything about issues. Anyway, I tried almost all of the Infamous ROM's(and all the kernels available with AROMA) as well as Cyanogenmod 10.2. All ROM's have major issues maintaining mobile data connection regardless of network mode or which cell I am on. Wi-Fi works flawlessly however. Also, to note, my fiance is running MK2 on her stock M919 so I have had a reference of which type of cell we are on and its signal strength.
So, finally I flashed the MK2 modem manually and rebooted into CM 10.2. That just made it completely unable to connect to any type of network although Wi-Fi worked just fine. So, now I am attempting to reinstall Infamous S4 from a full wipe to see if that will work, but after that I am out of ideas.

Have you checked your APN settings (versus your fiancés) to make sure they are correct? And to be completely fair, you could post in one of the many CM threads like this one here, you will target a much larger and focused support base. :good:
The whole mdl / mk2 radios are a mess. There are 2 radios, one for lte and one for hspa and below. The LTE one stays mdl and only the other is upgraded because of knox installation that some people are worried about (their warranty).
I believe what you may want to do is install the ota official for 4.3 to get all the correct radios and just forget about the warranty. There have been ways to reset the knox counter later down the road if you want to claim your warranty but I do not recall any guides.
I've started a thread here too for some clarifications on this subject so check that for answers too

First, there is currently NO METHOD to reset your KNOX counter, please do not give wrong information (which is why we have THIS thread).
Second, a link to this thread of yours would be useful, if you only linked it.
Third, "correct" radios are already freely available on XDA without taking the 4.3 OTA. He may have flashed an improper or incompatible modem.bin file, which is why his problem is occurring.

Correct radio's without knox means that there is still an old LTE radio which creates and has been creating lots of problems for people.
I don't care about a flash counter anyway, and sorry did not mean to spread mis-information.
My thread is here: http://forum.xda-developers.com/showthread.php?t=2609962
the only answer I was given was one that told me to do the exact thing I didn't want to do, which is to flash the GSM MK2, but leave the LTE MDL.
-------------
I'm looking to see if anyone can help me find a way to flash the OTA update which contains KNOX (which includes the MK2 LTE) and also the MK2 GSM radio's.
The only downside I see to flashing KNOX (and the MK2 LTE) is this flash counter. I believe I heard somewhere you may not be able to flash new kernels, but I'm not sure if that is correct or not. If it is correct and I can not flash new kernels, I also do not care and don't know why so many people are okay with LTE radio's that go out all the time vs a flash counter+stock kernel

It's okay, we are all learning about information . The modem.bin file you flash in Odin replaces your old one (which is why the name of the file HAS to be modem.bin, otherwise nothing will get replaced).
Why do you WANT KNOX? KNOX is part of the bootloader for 4.3+. The guide you linked is how almost everyone has updated their modems on 4.2.2 bootloader.
If you are on 4.2.2 bootloader, follow these steps:
1) Download the 4.3 modem.
2) Place phone in download mode (Vol Down + Home + Power)
3) Open Odin and plug into computer.
4) Select "Phone" and then choose the modem.bin file.
5) Uncheck "Auto-reboot"
6) Press Start and wait 30 seconds after it says "Passed."
7) Restart phone.
I can almost guarantee you that this will work because this has been proven to work hundreds of thousands of times. I am on 4.2.2 MDL LTE (since I am already on 4.2.2) and I just flashed the 4.3 MK2 modem. I have no problems at all with data now.
EDIT: I am also using a 4.3 MK2 modem on 4.2.2 and have no issues.

I want knox because I want the LTE radio which is tied to knox. I don't care if I have knox or not. My phone is not under warranty anyone, and if that is the only thing that is scaring people away then I have no reason to worry about knox.
I may try out this scenario but right now my phone reboots all the time and I've heard people having issues with LTE on 4.3 ROM's so I am not looking forward to spending hours configuring my phone only to wipe it all again, but it may work out better than I am thinking so I will give it a shot.
For reference, if there is a flashable full 4.3 ROM/.tar (with knox and the MK2 LTE included) out there and you could link me, I would appreciate it. I can't seem to find any which is odd.
Cheers

There are 4.3 flashable ROMs out there but they will not give you what you want. You will HAVE to Odin flash a stock file to get what you're after.
Here are some links for the stock MK2 with KNOX included (choose whichever one is faster). :good:

Open up odin, select PDA, choose the tar file you just downloaded.
Then put your phone in download mode (vol down + home + power), then connect it to your computer.
Once odin detects your phone, press start. It will take 15 to 20 mins and it will restart by itself.
After it reboots and for some reason you get stuck on the tmobile screen for more than 10 mins, go into recovery and wipe/data factory reset and wipe cache. Then your phone will boot up fine. Enjoy ^_^

Both M919's are set to fast.t-mobile.com, although I haven't checked to see if the settings all match. I will definitely check that later.
As for threads here and elsewhere to solve the problem, I have tried pretty much everything I have seen. Most of what I have been reading on both CM and custom TW ROM threads is "me too" or "I don't have that problem".

Click to expand...

You need to download and Odin flash the official stock N900T NE6 firmware.
Here is the direct fast download link for it:
http://www.androidfilehost.com/?fid=23501681358537528
The zip file also contains Odin, CF-Autoroot and TWRP 2.7.0.1 recovery.
Unzip the file into a new folder in windows desktop.
Be sure to go into recovery before Odin flashing NE6 and do a factory data reset
and a full wipe. Then Odin flash the TAR/MD5 firmware.
After successful odin flash, put the phone into download mode again and
flash cf-autoroot and the TWRP 2.7.0.1 tar files.
If you want more information and or instructions here is the link:

run triangle away v3.26.apk from chainfire, when you apply the info. it will shut down, power off, then boot to bootloader and flash firmware, that was the easiest way for the modem, baseband to stick....

Fix it! I think the baseband is partly to blame for the the data drops in nb4. And I'm getting way better battery life as well. To get the new baseband to stick download Triangle Away then reflash in Odin. Worked for me. Id recommend you wipe your data too. http://forum.xda-developers.com/galaxy-s2/orig-development/2013-10-04-triangleaway-v3-10-t1494114

Use Triangle Away to reset your flash counter and make it official. Then flash NE6 with Odin/Mobile Odin to get latest baseband.

do i need to be on stock nb4 kernel then use triangle away or does using triangle away good enough to start the process?
Just did this today, you need to be on a stock samsung kernel for triangle away the warning is VERY clear in the app. Personally, when a developer says "do it this way, or you will have a problem" I take their advice.
Read carefully and follow ALL of the instructions very carefully as well.
There are at least two different threads covering how to flash this. One has "stock ODEX" {{ http://forum.xda-developers.com/showthread.php?t=2713354 }}, the other has "stock Deodexed" {{ http://forum.xda-developers.com/showthread.php?t=2761451 }}

There is "NO" way to update officially to NE6 if you have rooted, modded, used a custom recovery in the past on you Note 3.
If you have tripped knox in any way, you will already have the bootloader you need to be on, and can flash the new stock rom from the forum.
If you have not tripped knox, have no custom recovery, have never done anything to your phone, then you are free to get the update as TMO pushes it out.

It does exist, but just flashing the modem alone won't solve your problem. I tried it yesterday. Seems to need something else. I flashed just modern and left the rest of phone the same. Still having to toggle every so often with the ne6 modem in here.

Good luck. I'm switching to at&t this next week. Just paid off my eip. I just want functionality. Going to hit up an aosp ROM later today to compare. When I cone back to touch wiz maybe *all new roms will be updated to ne6. It's weird though because I used to not have any issues, then a week ago I couldn't connect to anything on lte. Was hoping it was just a modem issue, but probably needs kernel as well.

That's what I told the t-mobile rep the other day. Phones will be bought through t mobile, but as far as reliability I'm going to have to go with att. I would have stayed with t mobile if they didn't cancel my companies discount program. It was 15%, but my company decided to no longer offer the program. With att I will have a 25% and no contract. Can't really beat it.

I also tried TMOBILE services - I could not get any signal strength inside my home so the only way to make calls was to use WIFI Calling - (probably why they built that feature in the first place)
Then the data speeds were very slow - the fastest speed I could get around town was around 6mps - but on ATT I get consistent speeds over 20MBS and soemtimes 35MBS and higher - download speeds have been also very good -
I have seen others praise TMOBILE for the high speeds they get - so maybe things are better in their market? Don't know - just that they suck where i live...

In my area they are great if outdoors, but don't cover the whole city. I also have zero indoor penetration. They have bought a ton of 700 MHz spectrum off of Verizon, so that portion should get better soon.
Their LTE is fast where I live if you can get it. I got 35 Mbps the other day. But again, I have to travel outside of the city on jobs and am quite frequently without Wi-Fi or service.... So the jump is going to be made. I use my personal cell phone for work, and if I don't have signal, that is money lost...

Hey guys! This might sound noobish, but i really never flashed, rooted, or anything on a droid/etc before. So atm I bought a galaxy s4 for my dad, and tried unlocking this stupid phone, but unlocking thru the dialer didnt work(couldnt even get *#27663368378# to work, when using *#0011#, still couldnt do anything.) All i know about it, is that it recognizes the European sim card, but the simple mobile(usa) sim card doesnt recognize, can't make calls, etc, as when you try to make a call it says "cant register to network" or w.e. So i was wondering what should I do? Do i need to flash the modem? rom? Root it? I want it to be able to work in global, in usa and euro.
On another note, I got my other phone that's on ver 4.2.2. Should i try upgrading my modem/baseband from mdl to nb4? Anything new with the new modem or anything i should update? Since i cant update OTA anymore on my 4.2.2. lol. Any suggestions would be awesome Tell me from your point of you, is it better to stay at 4.2.2? or just get the 4.4.2, and should i root my phone?

To unlock your dad's phone the guide you linked to should do what you need done.
As far as your phone still on MDL, you should be able to use the old method through the service menu to unlock if that's what you wanted to do. You can update your modem/baseband if you desire, although if you're staying on stock 4.2.2 TouchWiz there is really no need to. It's only when you flash ROMs based on 4.3 and above that you run into issues using the MDL modem/baseband.
To add to lordcheeto's post, there's a difference between MDL bootloader and the MDL modem. When the S4 was released with Android 4.2 it had an unlocked bootloader (MDL), but with Android 4.3 and 4.4 Samsung included new security software called Knox. Knox doesn't prevent rooting, but if you flash a custom recovery such as CWMR, TWRP, or Philz Touch then a security flag will be irreversibly tripped which voids your warranty. Because this Knox software is tied into the bootloader, developers found a way around it by extracting the modems from 4.3 (MK2) and 4.4 (NB4) firmwares which allows us to keep our MDL bootloader and still use 4.2, 4.3, and 4.4 roms. The advantages are that we keep our warranty and we're able to use any 4.2+ rom. We can downgrade and upgrade easily while Knox phones can't.

To unlock your dad's phone the guide you linked to should do what you need done.
As far as your phone still on MDL, you should be able to use the old method through the service menu to unlock if that's what you wanted to do. You can update your modem/baseband if you desire, although if you're staying on stock 4.2.2 TouchWiz there is really no need to. It's only when you flash ROMs based on 4.3 and above that you run into issues using the MDL modem/baseband.

Should i keep the 4.4.2 kitkat thats not working with my usa sim card atm? Or should i flash it to 4.2.2. ADL? If having 4.2.2 is better doing that guide i put link to above, then give me a good tut on doing it, need to do it today xD THanks in Advance!

To add to lordcheeto's post, there's a difference between MDL bootloader and the MDL modem. When the S4 was released with Android 4.2 it had an unlocked bootloader (MDL), but with Android 4.3 and 4.4 Samsung included new security software called Knox. Knox doesn't prevent rooting, but if you flash a custom recovery such as CWMR, TWRP, or Philz Touch then a security flag will be irreversibly tripped which voids your warranty. Because this Knox software is tied into the bootloader, developers found a way around it by extracting the modems from 4.3 (MK2) and 4.4 (NB4) firmwares which allows us to keep our MDL bootloader and still use 4.2, 4.3, and 4.4 roms.

What do you suggest? Should i downgrade to 4.2.2.? Or just run with the guide i posted above keeping the 4.4.2. NB4, I just need it to run so i can call, use date, and go to euro and use in usa ofc. Ive been using my 4.2.2. pretty good so far, been almost a year and had no problems with it, should i worry about updating my modem on my 4.2.2.? or anything important, etc? If i should go with 4.2.2., i need to root it eh? If so, point me to the good rooting method and downgrading to 4.2.2. frin 4.4.2 Kitkat(updated OTA). Thanks in Advance!

I thought the answers given were pretty clear... I'm actually confused about what phone you're asking about, and if there are, in fact, 2 different phones in question... My answer will be a bit lengthy, but I hope that you can put 1 and 2 together and apply the information I am about to type to your particular situation: Also, I'm not trying to be a ****, just concise.
In reference to the S4 that is on 4.4.2 (NB4) firmware: The unlock method which you posted SHOULD enable the device to use different SIM cards and function in "euro" and "usa." That includes making calls and using "date" (data?) as you mentioned. As far as your question on reverting that particular device: There is no way whatsoever to downgrade the firmware on a device running either stock 4.3 (MK2) or stock 4.4.2 (NB4) obtained by flashing via Odin, Kies, or OTA; so that idea can be forgotten about. The unlock method, from what I gather, simply reverts the modem and allows you to use the old unlock method. then returns the modem to NB4. It does not touch the firmware, bootloader, or anything other than the modem/baseband.
For whichever device this applies to: there should be no need to root either to accomplish either goal. If you wish to root, then I can point you in the right direction; otherwise, if you haven't needed it so far and don't foresee needing it in the future, I say don't worry about it.
As for the device running 4.2.2: if you have had no troubles with reception, then there is no need to update your modem/baseband. There are really only 2 times that updating your modem would come in handy. 1: If you are having reception problems, or 2: If you plan on keeping your bootloader at MDL AND using custom ROMs 4.3 and above. The benefit of this scenario is that keeping your bootloader on MDL means that your device does not have the KNOX-implemented bootloader and can easily be reverted to a completely stock state for warranty purposes yet you still get to have the most up-to-date version of Android. If neither of those conditions apply to you, then there is really no real need to update your modem.

The guide you posted should work just fine. Just follow the instructions.
Also, I left out one of the most important parts of having the modems extracted from the 4.3 and 4.4 firmwares. The reason for extracting the modems is so that we can flash them separately from the official firmware which would upgrade us to a Knox bootloader. Using the 4.2 modem with 4.3 and 4.4 roms causes data and sound issues that make the phone pretty much unusable. The same goes for using the 4.3 modem with a 4.4 rom. With the extracted modems we can flash them separately for whatever Android version we're using and have full functionality and retain the MDL bootloader and all it's perks.
If you use a 4.2 rom, you'll need to make sure to flash the MDL modem with it.
For 4.3 roms, you'll need to be on MK2 modem.
4.4 roms require NB4 modem.
As long as you don't update to official 4.3 or 4.4, you'll be able to use any version rom you want according to your preference. Personally, I use 4.4 roms, but it's nice to have the option to go back to 4.2 if I want to. Once you SIM unlock, it should stick between all versions. You should be able to flash any rom that you want without having to worry about going through that process again.

So If i was on 4.3, and it updated to 4.4.2 kitkat, means it went to the official update eh? As "lordcheeto03" said that once u go to 4.3 or 4.4.2 you cant go back to 4.2, the menu options and w.e go updated, the "about me" is now yellow, the top border of the phone is grey, etc. The new security is enforcing, I guess I'll try the guide i found, hope i don't do anything stupid or skip a step(usually doesn't happen) but feels kinda weird doing things the first time.
On another note, if a phone bricks or in a loop, etc can it be solved? So i still have hope if something goes wrong xD
edit: The guide i link that i found, it works for all m919 models? Since i got t-mobile, not sure if all models(tmobile, att, etc) have the same modem, wouldnt want to brick cuz of not flashing the correct file, w.e(disregard this, i forgot i posted in the t-mobile section, man sometimes i feel like an idiot because i dont double check xD)

Once you hit 4.3, you lost your ability to downgrade. You can upgrade, but you can't go back. Rest easy, as long as you can get into download mode, you can recover your device. Bootloop, soft brick, whatever; as long as Power + volume down brings you to download mode everything is still OK. Just read the directions a few times.. get used to the idea of what's going on, double check and make sure you have the right software and files, and jump in. You'll do fine. Even after years of jailbreaking iphones and rooting Droids, I still get nervous whenever I have to fire up Odin; but just remember... many many others (more than have posted in that thread for sure) have done the same thing you're about to do, so as long as you follow the directions you will be fine!

These files include modem.bin that is required... I'm not sure why the OP linked to the entire firmware instead of just those links, but anywho...
The NB4 modem can be found in this thread. It's only ~20MB.
The MDL modem is in this thread. It is ~25MB.

Flashed ADL using odin, somehow got the menu to work(couldnt budge for some reason to umts), went thru all the steps, it rebooted, put it back to download mode, and flashed it back to nb4. Put my simplemobile simcard in, still nothing, am I supposed to put a different sim card in like ATT or something for it to work? Confused why it didnt work, yet it still detects the MTC european version simcard(not in service, but it had a pin set on it, so it always asks you to unlock the sim with the sim pin u put on it to view ur files on it, etc). Am i doing something wrong? I could give you more info on the phone...

Just wondering if there's anything special or cool about getting your phone updated to the newest version available, I got my phone already with a custom rom on it(modified), can't update it thru OTA, or 4.2.2. is till a pretty decent Version to sit and and still kick ass? ;p
IMO, i like KitKat (4.4+) more than Jellybean (4.3-). You can update via Kies if you want but you can't go back. Or you can just stay with the bootloader you have now and just flash custom ROMs, kernels and modem. 4.3+ has KNOX security but if you don't have a warranty then tripping the "KNOX counter" is nothing to worry about.
Nah, dont have a warranty on it. Got it with a custom rom, i guess some1 flashed it before selling it to me, it runs good n wut not, just was wondering wut i might have been missing out n w.e. xD if newer versions improve battery life consumption, makes it faster, etc, then it sounds good xD ill prolly try thru kies later n see if it goes thru
You dont HAVE to upgrade. Try Insane KitKat. Its a great custom ROM. Fast and good battery life. And if you download the sickness mods v5 (4.4.2) before he uploads v6(4.4.4), you can add whatever you want from the AROMA options.
Never used any of those custom roms.
On other hand, today i opened my phone to do some stuff on it, and it felt like some1 touched it(one of my bros), it wanted me to restart my phone to upgrade to 4.3 update. I guess somehow i got t-mobile OTA update and they clicked on it and downloaded the 700mb+ file. Oh well i guess, how good is the 4.3? Much better then 4.2.2? Or so so?
The new nh7 modem is tight. You can do this update because you are still on the MDL bootloader.

An OTA update will update your whole firmware. You might get another update for NH7 after you do that one.
Ahh I see, but OTA's don't usually change your bootloader eh? Just everything else.

Oh well I guess. Someone took my phone while playing games, and downloaded the new OTA, now it's going to keep bugging me to update it. Loved it at 4.2.2. Hope the nh7 is going to be better, heard tons of ppl having battery draining, bad reception, etc, maybe just a small % of ppl. not sure o.o Someone said nh7 is going to be smooth and fast, etc, haha that would be great rofl.
I updated with Odin and then flashed Insane NH7 ROM and haven't have any problems. But I have seen people saying bad things about their signal. I guess it's a hit or miss

Once you update whether OTA or Odin, you will have to root again. You can ignore the update. There is a way to stop the notifications, just use Google.

How good is that insane rom? I mainly use my gs4 for calling, navigation, listening to music(downloaded/streaming), streaming movies sometimes thru wifi, games sometimes, use apps to remove wasted ram/Junk files/help with battery drain, etc. Main thing is really i need is the good signal at all times, so navigation and all that crap works awesome, calling, net. Tbh id love to remove all the unwanted bloatware that i never use(but that can be done by rooting). Did you stay on mdl bootloader, n just flashed ur custom rom eh?

If all you've done is download the OTA but you haven't actually applied it AND you are still on the 4.2.2 MDL bootloader, I'd say leave your bootloader on MDL. I'm not saying don't run updated ROMs, I'm just saying not to take an official update. Use Odin to flash the newest modem and use custom recovery to flash any of the 4.4.x ROMs in the Android Development section, Original Android Development, or Unified Development sections. If you use custom recovery to flash the newer ROMs you still get the benefits of having updated firmware, you just don't end up having KNOX. Myself, along with numerous other users here, are still on the MDL bootloader, NH7 modem, and running modified/stock 4.4.4 NH7 TouchWiz ROM with no problems to speak of. The only thing about keeping the old bootloader, the only modem you can update is your GSM modem, not LTE; although as I said, I really haven't noticed any drop in reception... I still get full LTE whenever I'm in an area which has LTE penetration...

Should i upgrade my modem or anything to 4.4.4 version, or get a custom rom? I'm also running on network: LTE/GSM/WCDMA, or should i use something else that would run better everywhere? ;p I'm on simple mobile atm which under t-mobile i guess. Also, what are cool useful apps for gs4 for rooted phones? And anything else that might be useful to add here Thanks!
I just joined in the past few days because I decided to try different ROMs on my i747. This is my 1st ever post, and I thought I'd try out this rooting and flashing that I'm missing out on.
First of all, THANKS to EVERYONE that posts here for all of the help given to me and that others have used. Nice to see people helping out other people in such ways.
Second, I have successfully put a few different ROMs on my i747 over the past few days and can't believe how easy it was. I was always scared to do it. I decided since the thing was just sitting in a drawer not being used "What's the risk?"
Third, my actual issue...No matter what ROM I have on the i747, it will not connect to Wi-Fi at my work. FYI, I work (in IT ironically) in a very large company with hundreds of access points around the campus. So I know it is not the network, as we would have others with the same issue. It connects to all other (that I've tried so far) Wi-Fi networks with no issues.
I just don't understand all the terms bootloader, firmware, kernel, modem etc. I read decriptions (on here) trying to explain and I just can't grasp it.
I was on stock with whatever the last OTA update from AT&T was. I updated the boatloader (I believe) from NE4 to NJ1 to NJ2 using this thread. At least, I'm assuming I did it right. Nothing failed and the Phone Info app looks like it worked. https://forum.xda-developers.com/galaxy-s3-att/general/ucuemjb-to-ucufne4-firmware-update-t2808654
Anyone can give me any tips on what I need to do to possible get this working? It's not really a huge deal breaker, it's just bugging me as to why it isn't working.
Thanks in advance!
You upgraded the modem/baseband software when updating the bootloader?

I'm guessing no. How do I do that? Don't want to brick it.
I found this link, but what firmware am I on? How do I tell?

Did you flash the zip or did you flash aboot.mbn? If you flashed the zip, the bootloader and modem would have been updated at the same time.

I flashed the zip.
So an unrooted stock ROM also refuses to connect?
