[T-Mobile Samsung Galaxy S 4] gargyagotra:
I never activated the device on a T-Mobile network and thats why T-Mobile support is unable to send me unlock code. They are saying that they cant unlock a device which was never registered on their network. I am currently in India and hence i dont have any other options to mod the device even if it means voiding the warranty.

Refer to my question thread here: http://xdaforums.com/showthread.php?t=2740536

All my assumptions are based on the discussion in the above thread. If there is no way to downgrade the bootloader , is there a way to flash my current modem back to MDL on the knox bootloader so that i can goto service menu as suggested in the above thread.

If there is any other way to solve my problem, i am open to suggestions. As you might have figured out that i am a newbie hence, i will really appreciate if you provide a detailed response.

Thanks

Finally got it to flash, not sure if it was just provisioning or what but the service kinda sacked for the first couple of hours but after that it's ran pretty golden, I haven't had any signal or data drops whatsoever.

Can I flash this modem via TWRP. I'm already rooted on 4.2.2 with TWRP. Plan is to flash this modem and then flash a stock rooted rom via TWRP. I understand it's better to have this modem. Is it necessary to flash via the ODIN in the package?

I don't think so man, u might be able to with mobile Odin but I doubt that also

Is there specifics to flash this modem. Am on hyperdrive rls13 and on android 4.3.
[T-Mobile Samsung Galaxy S 4] Mad_Technologist:
Thank you!

Thanks OP, I really appreciate the help. I am rooted on AOSB ROM with the 4.2.2 bootloader and MK2 baseband. I followed the instructions listed in OP 1st paragraph, used Odin and Modem from zip file, even though I had Odin already, and everything went smoothly. So anyone with a MK2 baseband and 4.2.2 bootloader should be able to do the same.
[T-Mobile Samsung Galaxy S 4] momsboy12:
Can i do this on metropcs? I have CM11 4.4.2 ..but the baseband is MF2 which im told is super old...i just wanna know if its safe to do??

Or can someone point me in the right direction?
[T-Mobile Samsung Galaxy S 4] Skipjacks:
As long as it's a T Mobile 919 S4 variant you should be able to.
[T-Mobile Samsung Galaxy S 4] momsboy12:
Alright, I'll give it a shot tomorrow..thanks!
[T-Mobile Samsung Galaxy S 4] Skipjacks:
Your phone. Your risk. If you brick it it's not my fault.

I don't think you are taking a risk at all, but that doesn't mean I'm right.
[T-Mobile Samsung Galaxy S 4] momsboy12:
Oh i know...no worries, i appreciate the help..ive been researching this all over and this thread seems to be my best shot for answers...the only thing i was wondering if being on cm11 would effect anything with the flashing?..And the fact im on such an old baseband that it wouldn't work?
[T-Mobile Samsung Galaxy S 4] Skipjacks:
You will probably have to flash it twice before rebooting if you aren't on a stock rom. Uncheck auto reboot in Odin.

Otherwise it won't stick.
[T-Mobile Samsung Galaxy S 4] momsboy12:
It worked! Thank you!!

And thank you to the OP! ^_^

How can I tell what bootloader I have?

Sorry for what's probably a silly question but, having only had HTC devices until now, I'm not sure how to check what bootloader I have on this device.

I know I have KNOX and that it's tripped (don't really care about the possibility of a voided warranty), but I'm seeing people reference their baseband as their bootloader and my baseband is M919UVUEMK2.

Is it safe to flash the NB4 modem from the OP?

My full specs are:

Model: SGH-M919 (purchased from a T-Mobile store)

Android: 4.4.2 (CyanogenMod 11 M6)

Baseband: M919UVUEMK2

ClockworkMod: 6.0.4.7

Also, I'm seeing people reference both "modem" and "radio" and, from my HTC days, there was just a "radio"; are people using the terms interchangeably, or are there two things that I should be updating in order to get better speeds, etc.
[T-Mobile Samsung Galaxy S 4] mrzhadow:
Yes it is safe to flash the nb4 modem only or the full firmware if you don't care about Knox being tripped. The nb4 modem does not contain the new LTE radio. But if you flash the full 4.4 firmware it will contain both nb4 modem and new LTE radio.
[T-Mobile Samsung Galaxy S 4] OriginalGabriel:
Awesome, thanks.

Just to make sure I'm not going to brick my device (I know there's always a possibility, mainly wanting to make sure my process is correct) ...

I can flash the M919UVUFNB4 from SamMobile to obtain the updated radio and modem, re-root with CF-Auto-Root, then flash TWRP, and then flash whatever ROM I want?

(Samsung devices are entirely to easy to work with, if that's the case ... and it scares me a bit coming from HTC devices where there were a lot more steps).

EDIT: Come to think of it, I should just be able to restore my CM11 backup rather than re-flash CM11 after all of the above.
[T-Mobile Samsung Galaxy S 4] sj808:
I flashed this thing like 4x in odin and it says it gone through. But when I reboot my phone and go to the settings to check it still says I have the mk2 baseband. I give up.

I am on the KOT49H.S001.VirginROM x3.1.1 and it says my device is a GT-I9505G if that is the culprit.
[T-Mobile Samsung Galaxy S 4] Skipjacks:
Uncheck auto reboot in Odin.

Flash the tar twice in a row without rebooting.

Now I bet its there when you reboot

Sent from your phone. You should be more careful where you leave that thing.
[T-Mobile Samsung Galaxy S 4] quasiperfect:
Manual Reboot

Regarding step 5:

I know about 2 manual reboot methods:

1. hold power button 10 seconds

2. battery pull, battery reinsert, hold power till vibration.

Are ther any others?

Which one should I use?

Thanks
[T-Mobile Samsung Galaxy S 4] sj808:
well. I tried to flash the 4.4.2 modem bin twice. First time went through. Second time I got a fail. (I had to reboot in between, odin wouldn't do anything if I didn't).

Now I can't start my phone. I get the "Firmware upgrade encountered an issue. PLease Select Recovery mode in Kies and try again".

So I'm assuming I have to flash the M919AVUAMDL from the odin thread?? I never went to knox (still on 4.2)

EDIT:

Just tried to "fix the softbrick" but I keep getting fail in Odin. I have no idea what to do anymore. SMH.

OK I know how to count but I also know how the major phone companies are so I have to ask this at 730 on a Saturday morning before my second cup of coffee. I'm 4.3, is 4.4.2 higher?

Please remember I have only had 1 cup of coffee
[T-Mobile Samsung Galaxy S 4] Nirrik:
4.4.x is higher than 4.3.x
[T-Mobile Samsung Galaxy S 4] cogito808:
Thanks for all the update. Took me several failures of booting into recovery, starting from off, and scouring through other posts to find the solution that worked for me so thought I would put my 2 cents in for others having problems with it sticking. I pulled the battery and booted directly to download mode (Press and hold Volume Down, Home and Power buttons, all at the same time). Flashed once with Odin without reboot on per OP instructions. Pulled the battery and repeated the process again. Presto, I am on the new modem. :good:
[T-Mobile Samsung Galaxy S 4] cosmos10040:
does this work if my rom is 4.4.3?
[T-Mobile Samsung Galaxy S 4] Nirrik:
Worked for me
[T-Mobile Samsung Galaxy S 4] Skipjacks:
Yes. .2 and .3 aren't dramatically different Android bases. So .3 ROMS will run fine on this radio.

That same, the ROM version will not have any impact on your ability to install the NB4, or any other modem. The modem will install fine no matter what ROM you have installed. A rom of a certain base might not run on an incompatible radio, but the radio WILL install.
[T-Mobile Samsung Galaxy S 4] cosmos10040:
this installed fine i did it up to 3 times, maybe 4 times but i cannot connect to any network. says sim not allowed to connect to this network. I have called my carrier they said nothing wrong on their end. im thinking its my sim...

Edit: it was my Sim BTW.
[T-Mobile Samsung Galaxy S 4] CollinsB:
Will this work on metropcs s4 os V4.3 (mk5)

I'm very confused about the op. It says this method is ONLY for the MdL 4.2.2 bootloader. And i think its says its Not for any 4.3 bootloader with Knox?

but then op says the process is compatible with any firmware also? That seems a bit conflicting :confused:

Can I use this on metropcs 4.3 stock rooted AFTER I have flashed a tmobile kitkat rom to it. So that it would hopefully fix any signal issues i might have. Since it will be a kitkat (NB4) rom I expect I would need to flash the NB4 modem

thanks
[T-Mobile Samsung Galaxy S 4] a103:
No since you already have Knox you shouldn't flash this. I think you'll have to flash stock 4.4.2 to have NB4 modem.
[T-Mobile Samsung Galaxy S 4] CollinsB:
why? :confused:

would it not work. or cause to brick. Or would it just be a matter of triggering knox. which is really not a concern for me

But as far as flashing stock 4.4.2. Do you mean odin flash?

again this is the metro pcs mk5 4.3. Which never got kit-kat update. Theoretically it can run tmobile software, as it uses tmobile airwaves.

But i would be hesitant. But what are your thoughts on that?

and if it is an odin flash, could you please link me to the tar.

or however to obtain stock 4.4.2.

thanks so much
[T-Mobile Samsung Galaxy S 4] rezik1:
I am having the same issue but just on a regular TMO S4 (M919). It is on 4.3 MK2 Bootloader. Ive tried to odin the NB4 modem alone and it didn't work, (maybe odin it twice?). i also downloaded the full NB4 firmware and tried to odin that, it flashes successfully. but the bootloader and baseband stay at MK2. Am I missing something?
[T-Mobile Samsung Galaxy S 4] Nirrik:
I had to odin flash the modem 3 times in a row for some reason but once I did it took.

[T-Mobile Samsung Galaxy S 4] marduk79:
Thank You

I was on 4.2 running a kit kat rom with which I had signal issues and after flashing the 4.4.2 MDL on the OP my signal increased to full bars. I think the overall signal is better than what I had when I was running the stock rom from T-mobile. Thank you for posting the file and directions. :)

FYI, for anyone trying to do this on a custom rom, boot into download mode (volume down + power) AFTER a phone shutdown. Not from the rom's reboot menu!
[T-Mobile Samsung Galaxy S 4] Skipjacks:
This....but if you forget to do this and remember once you are in download mode,..just flash the update tar twice.

Behind the scenes the same things that make it work are occurring. Easier to just remember to boot to recovery from power off though.

[T-Mobile Samsung Galaxy S 4] Okaham:
Hi everyone, I just flashed this modem, but now I don't have LTE due to the radio. My question is, is there anyway I can flash it? How so if there is a way? I would love to have LTE. I'm currently on Android version 4.4.2

TIA
[T-Mobile Samsung Galaxy S 4] lalec:
Flashing this should have nothing to do with whether you have LTE. Your LTE does need to be compatible with your bootloader version though. Do you have the MDL bootloader?
[T-Mobile Samsung Galaxy S 4] Okaham:
Yes, I didn't upgrade my bootloader. It shows up LTE now though, but how can I make sure?
[T-Mobile Samsung Galaxy S 4] lalec:
If it says LTE and you have data connection working, then you have it. LTE is not everywhere, especially with T-Mobile, so if the icon changes once in a while it does not necessarily mean that something is wrong with your phone.

[T-Mobile Samsung Galaxy S 4] JohnnyAn:
Since this should only work on the MDL bootloader, how do you tell which bootloader you have? Yesterday, I had flashed stock NB4 firmware, it seemed to stick after several reboots, then I rooted, and flashed a ROM, but after flashing the ROM, my baseband reverted back to MDL. Does that mean I have the MDL bootloader again and can just try flashing the NB4 modem? Or do I have the NB4 firmware still and just the modem reverted back, and that's why it's showing MDL baseband again?

I guess bottom line is, does the baseband tell me the firmware or modem that I have? And how do I find out what the other one is?
[T-Mobile Samsung Galaxy S 4] lalec:
You can see bootloader info when you boot into [Odin] download mode. If you installed full stock NB4 you do have Knox already though. And no, baseband version by itself does not tell you what bootloader you have.

I would like to update to NB4 modem on my AT&T i337. Flashing by Odin fails everytime. Can the NB4 modem be flashed on the AT&T i337 on an MDL bootloader? Would flashing an AT&T KK modem (NB1 or NC1 modem) correct this if the NB4 modem isn't compatible? I haven't been able to resolve this yet...
[T-Mobile Samsung Galaxy S 4] saagar_mistry:
Hey guys, a little help here.

I recently updated to 4.4.2 firmware nb4.

I have odin the firmware 3 times but in setting under baseband version it still shows mk2. It does say ANDROID VERSION 4.4.2 but baseband version doesn't change to nb4.

Also, wifi doesn't work in this. I downloaded firmware from 2 different places but still the same result.

Can anyone help with this? I wanted to root it after but since it shows mk2 i can't root it with towelroot method.

Have my screen shot attached below.
[T-Mobile Samsung Galaxy S 4] lalec:
First, there is no need to quote the OP. Having said that, your going to have to odin flash a 4.4.2 full stock tar or see if samsung kies software can fix you up. If you are new to this Kies is easiest.
[T-Mobile Samsung Galaxy S 4] saagar_mistry:
Sorry abt that. And So I download kies and check for software update?

I thought wat I flashed through odin was the 4.4.2 stock, no?

So i installed kies and everything it says latest firmware installed. :/
[T-Mobile Samsung Galaxy S 4] lalec:
Sorry if I missed it but I didn't see where you told us exactly what file you flashed through Odin. Many of the ROM packages available for download do not include the radio part of the firmware so that is probably why you have the older radio. If you can find the radio firmware that also can be flashed through Odin but Samsung Kies software (if you decide to go that route) will bring everything to the same version level. Kies may think you are already up to date but it will let you download the latest complete stock ROM and install it. Just be sure that you have all your important data backed up. Good luck!
[T-Mobile Samsung Galaxy S 4] vdavidm:
Do you solve it?
[T-Mobile Samsung Galaxy S 4] blek42:
My conclusion is that M919 modems can not be flashed onto I337 models. I flashed ATTs NB1 modem for KK.

Can I?

I have been dealing with this issue for some time now. I am having problems with data connection when making or receiving phone calls. I have been running with root for a long time and never had a issue. My phone drops from 4G or LTE with the use of any type of phone calls. It drops to HSPA and at times even the calls drop in me. And it don't rebound back to my 4G LTE for a long time. However, when I flashed back to a full stock ROM it's fine. I have tried just about every AOSP ROM with no success in this matter. So 3 questions, 1) If I flash this will it help? 2) If I DO flash this will it lock my device from root and/or will I loose my root access. 3) Is the modem even the problem? Please help.

Thank you in advance for your help guys.
[T-Mobile Samsung Galaxy S 4] rlichtefeld:
You don't say which modem you are on, but the newest NH7 modem seems to work very well for a lot of people that have upgraded to it.

1) If I flash this will it help?

Maybe, but can't hurt.

2) If I DO flash this will it lock my device from root and/or will I loose my root access.

Nope, won't lose root. Shouldn't lock the device.

3) Is the modem even the problem?

Don't know. Not sure what you are running.

Thank you for your response. Could you tell me what you would need to know to help me fix this issue? Illama attach a screen shot of my device.
[T-Mobile Samsung Galaxy S 4] rlichtefeld:
This first thing I would tell you is to NOT flash a T-Mobile US GS4 radio/modem. You don't have a T-Mobile US GS4 phone. The links in this thread are for the SGH-m919 model.

You need to find a thread for your model phone. You seem to have a Galaxy Note 3, since your model shown in those photos is SM-N9005. Flashing radios/firmwares for the wrong type of phone will most likely not work, and more likely brick your phone.

Try this forum and ask your questions there:

I don't have a Note 3, and don't have any experience with it, so would not want to answer any questions about it.
