Better MODEM than UVUAMDL?

Hello all.
Is there another modem than the UVUAMDL version for the SGH-M919? Or a way to flash say, a i9505 modem to the M919?

The latest modem as of this writing is the UVUEMK2. Take a look at this thread here to see how to get the file and flash the modem.
Do not flash any other modems except the SGH-M919 modems. Flashing other modems will result in an inability of the phone to boot.

The thread you linked indicates to flash the UVUAMDL, and not the MK2.

No. There's no need to worry about Knox when it comes to flashing the modem. The only time you need to worry about Knox is if you flash the 4.3 stock recovery and ROM.

Much Appreciated

This totally worked. Thanks. No knox and new band. I'm still having a coverage issue however.

I'm also having issues with coverage. I came from a 4.2.2 ROM with MDL radio. Flashed darthstalker 4.3 ROM and I rarely got more than 1 bar of signal. So I flashed the Mk2 radio via Odin and still the same, one bar everywhere I go.
Any one else experience this?
Is 4.3 more accurately displaying my signal strength?
Or is this just normal?
My speeds are still pretty good with 1 bar....15mb/s down, and 2m/bs up
Sent from my SGH-M919 using XDA Premium 4 mobile app

getting the same thing as well
did the flash to mk2, and, with all of you, i'm getting just 1 bar. didn't bother to check it since in my room, i tend to get at 2-3 bars; but, outside of that, the signal is usually quite strong.
another note, i'm using infamous alpha s4 12.04 rom, i'm not able to send mms or receive mms at all, period (while wi-fi is on). not sure if this is the same for all other 4.3 roms out there. i know of the data drops and what nots; but, haven't seen or read anything of not sending and receiving mms. usually, when i send mms, previously on infamous alpha s4 11r2 rom, it would go through just fine with no problem. the thing is, when sending mms it goes through 4G LTE since the 11r2 rom does not have wi-fi calling at all -- what this means is that even when on wi-fi the 4G LTE would come on the notification does it's sending and receiving animation and the mms would go through just perfect. but with the 4.3 12.04 rom it won't do that.
the only way to send mms, i found, was to disable wi-fi and wait for 4G LTE to kick in then send the mms. i don't like doing that, LOL. i like to be able to send mms even with wi-fi on without having to disable it (like with the 11r2 rom)

I have posted the solution to the signal problems you all are having in another thread. Go here and follow the instructions to resolve the issue.

odin question

Im trying to flash an att modem on the tmobile note 3, ive read ppl do this... but pc odin errors out. Ive been able to do it, I think, with mobile odin when I was using a n9005 rom but only because the n9005 is supported.
The reason I think it did flash was because although it still said I had a tmobile modem on my settings/about, the phone did get better signal and ive read that happens a lot, where you flash a modem and it doesnt say its the version you flashed.
Anyways, how can I successfully flash it aaaand for it to say I have the modem I flashed in my settings>about?

Theres a thread on this already. Some claim better signal after flashing the modem via mobil odin but then again others noticed nothing. I personally didn't notice any signal strength gain and I don't think the modem really even flashes, just my 2 cents.

I was running the omega 9005 rom, you can even change your build.prop to the 9005 and it will flash the modem with mobile odin. I've tried flashing just about every ATT modem out there with pc odin and they all fail right at the end.

[Q] Bootlooping despite flashing via Odin and installing CWM

Guys here is my problem. I tried to upgrade my Samsung N7105 to 4.3 via OTA and it got stucked on bootloop.
I tried to access recovery mode but it fails, only download mode.
What i did is I downloaded the official 4.3 firmware at SamMobile and flashed it with Odin 3.09
Based on Odin it is successful but im still stuck on bootloop and recovery mode cannot still be accessed.
Tried to root it also and installed CWM to recover. I was able to to access CWM
so i restored factory setting, wipe cache and dalvik cache but still the phone bootloops.
Any suggestions on how to resolve my problem?

just to add, i think i tripped the knox warrant void. its value is now 1 what this means?

Simply flash philz v5.00.5 and it should solve it, here's the link: http://link.tapatalk.com/api/click?...rs.com&subid=c157297d1a1ff043255bfb18530caaa2

Was able to access custom recovery upon flashing. conducted wipe data / factory reset and wipe dalvik cache but still bootlooping was experienced. Is my phone dead already and needs replacement?

After flashing the philz, try flashing a custom ROM and see if u will unstuck from the bootloop, try cm 10.2, it's very light and mostly bug free

Now working cm10.2 but now my next problem is there is no signal. it appeared that imei value is null. how do i repair this? thanks!
By the way after successfully running on cm10.2 I tried to reflash again with stock firmware. bootloop again. i think i will be stuckon using custom roms for now. The only thing I need to address is the no mobile signal problem.

OK so the bootloop problem is done and don't worry there are a lot of amazing custom roms that are based on the stock one and even better features like the note 3 features, as for the imei, please tell me you did an nfs backup if you do, there are a lot of ways you can restore your nfs backup, if you don't have an nfs backup, I don't know what to do.

Sorry was on vacation for a long time. I wasn't able to update this thread.
Problem right now is I forgot to back the EFS so when I flashed CM 10.2
There is no baseband and IMEI is null. Tried to flash n7105 modem but still it still doesn't work
Have read that I should flash stock firmware to fix baseband and IMEI but 4.3 firmwares makes my phone go on bootloop.
Should I wait for 4.4 update? I want my phone to make it usable again.
My phone right now is useless and works like an itouch hahaha
Any suggestions???
Need expert advise

You may try Hurricane modem changer and experiment with various modem versions. It's a longshot but it may help. Try finding very old modem version and flash that.

Hurricane Modem Changer is that an application?
Where to get it? Also, will it there be a possibility that when I flash Official 4.4 kitkat (when released) on my n7105.
Bandwidth and IMEI will be restored? I'm leaning towards to come back to touch wiz though many of you guys might say that a custom rom might be better.
For one thing, the problem in my n7105 started when i upgraded to 4.3 via OTA

No, it's for N7100 only - the modems are completely different (3G vs LTE).
Please read the original post carefully before flashing, if the HC was not protected you could have lost network functions completely.

Im using an n7105 model. Guess this will not work. Any other suggestions?
From what I understand, the quickest solution is to flash stock firmwares however, i'm quite disappointed that
almost all 4.3 firmwares from sam mobile doesn't work in my phone (always bootlooping)
A technician told me that I should wait for the 4.4 kitkat release, since it might work for my phone.
Now my problem is, I need to have the phone operational. so im willing to flash custom roms for the meantime
but the baseband problem is really testing my patience. hehe

It's pretty strange really as stock firmwares are a complete set of bootloader/modem/system that should in theory work perfectly well together without any incompatibility problems. Have you ever tried to install one of them without sdcard and/or simcard installed, maybe you have some leftovers from previous system (Android secure directory) that causes bootloops, also did you completely clean internal sdcard prior to flashing, it may create the same problems as external sdcard.

im not sure if i cleaned the internal sdcard prior to flashing.
It started with the OTA update that failed then I tried to flash stock firmware via odin
do i have to do a pre-requisite before flashing it again? so you are suggesting to remove the simcard and external sd card prior to flashing?

Can't get i337 modem to stick on my M919

Hi all,
I was hoping one of the resident geniuses could help me here because searching and experimenting haven't worked yet. I bought a i337 because I'm on AT&T and when I found I could only run TW roms via SS (it was already on 4.4.2), I bought a M919, and I've got it rooted and running TWRP 2.7.0.1 and some new roms. I've been able to flash i9505 and M919 roms and then an AT&T kernel, but whenever I flash a i337 modem it doesn't take. The baseband continues to show it is on M919 NB4. Can anyone help me understand how to get the i337 modem? I can make and receive calls, but do sometimes see some signal drops and I understand this is the way to go.
Thanks!

I meant to mention I am flashing via recovery, and I understand ODIN may work but that runs the risk of impacting my bootloader (which I think is bad, as i337 is locked and I have a M919 anyway)? Can someone confirm? I'll keep trying recovery zips, but I wonder if it's something in the Tmo NB4 or bootloader keeping it from sticking?

Do not flash i337 modems.. What was the firmware you were on before you started flashing?

The phone came with latest Tmo firmware and the NB4 baseband. I'm running Phoenix ROM now, Ktoonsez kernel. Can't say for sure yet because I just got on this combo, but as I've been testing over last 24 hours I've seen a LOT of my phone dropping signal when the screen locks or sleeps (I think). I get the crossed circle and I have to go into Mobile Networks and have it search for a network to get my cellular signal back. So it isn't the Tmo modem impacting this? Will I get LTE? Are there any better options if the signal keeps dropping short of going back to that bloody i337?

Try flashing fenny's NB4 firmware with Odin, the modem shouldn't be the problem there have been people with same issues running T-Mobile. Flashing firmware should fix it.. Try running stock for a few days and see if you keep getting drops

This really can't be repeated enough.
NEVER flash modems meant for another device. Never.
Ever.

Man, I could swear I've seen folks recommending to do exactly that for all the bands to work properly and for the best signal. Thanks for setting me straight folks!

[Q] What do I flash to get SGH-M919 working again?

Hi xda, I hope your Friday is going well.
EDIT: My calling problem was not fixed. I reflashed 4.4.2 NB4 Modem (twice to make sure it stuck) and the calling still does not work. Did something just completely fry when I had CM11 on this thing? Any ideas anybody? I don't even hear a dial tone if I am the one dialing out, the call still goes through though.
Everything below was my original post which has been resolved, didn't want to start a new thread though.
-----------------------------------------------------------------------------------------
TL;DR: My T-Mobile Samsung Galaxy S 4 (SGH-M919) is unable to boot stock rom, and I am unable to enter recovery. I get seandroid messages trying to do either. Fortunately, the phone can enter download mode. What do I need to do or flash to get this phone booting again? Thank you in advance for taking the time to read and help out.
Below is the long story with details:
1. The phone was given to me running stock Android/TouchWiz. Unfortunately, I do not know what version but I assume it was whatever was the latest version as of late April.
2. I rooted the phone using Odin and CF Auto Root.
3. I created a backup of this newly rooted stock rom.
4. I flashed Cyanogenmod 11
5. After a while I discovered that I could answer calls but I could not hear nor be heard during the call.
6. I restored to the stock rom using the backup I made in step 3.
7. The calling issue continued, so I figured I would just unroot and go back to like-new factory settings. This way I could take the phone in to be repaired or whatever.
8. Following this thread: http://forum.xda-developers.com/showthread.php?t=2336392, I attempted to flash k0nane's UVUAMDL Official Tar
9. Odin got stuck connecting to my device, I believe it was because I did not run Odin as admin. I pulled the battery and repeated this step while running Odin as admin.
10. The flash was successful, however during the phone's first boot it got stuck on the T-Mobile splash screen for about 30 minutes or so. I pulled the battery again.
11. Anytime I put the battery back in the phone, it will attempt to boot and hang at the T-Mobile screen, I believe this is a boot loop?
Looking online, people suggest going into recovery and wiping but I cannot enter recovery. I just get the seandroid not enforcing messages. I'm very hesitant to keep looking through the forums and trying things because I feel like I'm on the edge of bricking the phone if I haven't already.

I don't think the flash was successful because it wouldn't give you those messages, and you would need to flash either 4.3 or 4.4.2 not 4.2.2 (MDL) Try flashing a newer firmware version.. If it was updated to the newest then I would try 4.4.2

Ok so I flashed the wrong rom then. I hate to ask but where could I find a 4.4.2 stock rom? I just found a rom I believe will work but the file is titled "M919UVUFNB4_M919TMBFNB4_TMB" not sure if this is 4.4.2 or newer?

This is where I obtained the rom above that I wasn't sure was the newest.
I flashed this rom and everything worked, thank you both.
Any ideas on what happened with the phone call issue? My friend that gave me the phone said it was working just fine when she had it, so I assume somehow the rooting or CM11 screwed something up? Weirdly, calling through WiFi works just fine.

The only thing that can foul up your phone like that would be a bad cm flash or preflash, it's super important to read and read again, check the thread for support from members and resolutions to problems before you consider the build for your phone. Ask questions and double check everything before you take the plunge.
I assume that the calling problem is fixed, a corrupt modem may cause that and re flashing the modem will correct this.

My friend gave the phone to me. She got an S5 and didn't want to bother with selling this S4 so she just gave it to me. It was completely pure and stock, with calls working. Something screwed up during the CM11 flash I guess.
WiFi calls still work, everything works except calls.
Maybe I'm doing something wrong? I flashed the sammobile NB4 tar twice via PDA in Odin as usual. For the modem, I flashed the modem bin via Phone in Odin twice. Thank you for your help, by the way.

New term for CM, "complicated maneuver" ,.
Reflashing firmware may do it. Can't hurt either.

I flashed both Fenny's firmware and a baseband he also provided. Did both twice, and calls are still not working.
I was doing some research on this whole "Radio: Unknown" thing and I started seeing threads talking about flashes corrupting the phone's EFS partition. I never made a backup of mine, so I have nothing to restore to. Is it possible that I could use someone else's EFS backup and then use it to restore my phone's EFS partition? Does it work like that?

No it will not work, this is device specific afaik.. Like I said earlier, I recommend you call T-Mobile for a replacement

Flashing modems and such with a custom rom installed often fails. Did you try doing a restore to full stock using Odin?
It sounds like the phoen has Android 4.4 on it already so you will need to flash the full 4.4 package (can't go back to 4.3 or 4.2)
Try and, boot hte phoen without modifying it, and see if calls work then.
The EFS thing is about the IMEI number. Does your device show an IMEI number in settings? If it does, your EFS isn't the problem. If it doesn't....well then yeah. Problem is pretty much narrowed down.

I have restored the phone to full stock and have been using it that way since I started this thread. Everything is just like fresh from the factory (except for the knox counter being tripped obviously). Calls still didn't work. An IMEI number still shows up the phone's settings. Using WiFi calling hasn't been that bad at all, but I'm screwed in the case of a real emergency with this thing.
