M919V missing LTE after reboot - T-Mobile Samsung Galaxy S 4

Hi everyone!!
I got my SGH-M919V in Canada couple days ago. Untill now I've seen a friend of mine playing with his M919V to enable LTE and he did! Now I'm trying to flash the same modem ( M919UVUAMDL from T-mobile ) into my device and something very curious happened: the Odin didn't show any error, BUT after the device reboots, the baseband still the same M919VVLUAMDC as before. In theory, the M919UVUAMDL modem should enable 6 LTE Bands (1, 2, 4, 5, 7 and 17).
Any idea about what could be happening?
Could anyone with M919V version try to flash the M919UVUAMDL modem, please?
Here are the steps:
1) Download the T-Mobile firmware from http://www.sammobile.com/firmwares/1/?model=SGH-M919&pcode=TMB#firmware and extract.
2) Find the file "modem.bin" and move it to another folder. This file should be about 50MB.
3) Put phone in download mode and plug in USB.
4) Start Odin software.
5) Select "phone" and select the "modem.bin" file.
6) Only thing checked should be "Auto Reboot"
7) Hit Start
8) Let it reboot and after that you should be able to connect the LTE network.

Hi there.
Did u get the answer to this?
I have SGH M919V from wind mobile and baseband is M919VVLUAMG1. I want to use it with Bell LTE sim. But when I try using bell SIM it connects to 3g only. Instead I should get LTE speed. And moreover when I try forcing LTE with BELL SIM, I lose the calling capabili5y but LTE works just fine.
Plz help

[QUEST] 4G LTE working T-Mobile radio/modem on AT&T Note 2 or Viceversa

Is there currently a working T-Mobile modem that gets 3G on T-Mobile for the AT&T note 2? Instead of the typical Edge. (same as on Note 1) I have my AT&T Note 1 with 3G on T-Mobile... Any releases yet for the Note 2? I already ordered the dual sim card adapter for the Note 2...

I can't seem to get a straight answer on this either. I have been searching for 2 days now and I haven't been able to find any solutions. I have jediX on my unlocked AT&T phone with a T-Mobile sim and all I get is Edge. ive tried to put on the T-Mobile Radio and it just boot loops me.
I may have to try and find someone that wants to trade phones with me at this point.
I believe that most of the T889 roms have a radio built in.. Have you tried that?

yes i have, when i flash other roms that say the radio is included, it still shows the AT&T radio under settings>device info.
I have Jedi -X4 for Build number but,
i317UCALJ2 listed as the Baseband Version.
Model number shows SGH-T889.
if i try to flash a the T-mobile Radio, it just boot loops.

I have only just started looking into this myself and was expecting a working T-mobile radio that can be used on AT&T (or Rogers) to be floating around, considering they are all using hardware revision JRO03C.
Any help would be appreciated.

Please clarify: you have a T889 (TMo N2) device using an AT&T SIM, in an area confirmed to have AT&T LTE service, and you're getting no LTE? Have you tried flashing the modem package off an i317 (AT&T N2) onto your device to see if LTE gets activated that way?
Did you tried *#2263# and then u can choose lte 17 for att.good look ..
I didn't try those two, but I will right now. Tried another method using a long input string, but it didn't work.
Yep the *#*#4636#*#*doesnt work on theese roms, however the*#2263# works on the x5 rom but not on the 4.1.2 lk7 roms.on theese roms u can choose lte and hspa from mobile settings but there is not lte only option.do u have a succes with the code ,by the way you can try hspa plus on 1900 mhz on tmobile card with that code too.i tryed it and I can confirm it is 21mbits for now.

TMobile Modem on Galaxy Note 2 ATT i317
I am in the same situation as the OP. Looking to flash a T889 modem onto an ATT Galaxy Note 2 (i317) similar to the solution for Galaxy Note 1 ATT (i717) users using Tmobile network (by flashing a modified Amaze? modem).
Anyone successful in getting 3g TMobile speeds with their Galaxy Note I317?

LTE should work if you do that, but make sure your IMEI is still OK, and have a backup phone if you try flashing back the T889 modem. My phone is stuck in a bootloop since trying to go T889V -> I317M -> T889V.

I have an AT&T note 2 unlocked working a T-Mobile sim and 4G has been working from the start!
Did you double check that you're in a strictly AWS area, spectrum-wise?
Oh, and quick update: I was able to get the phone to boot with the I317M modem, switch it to diagnostic mode and fix the EFS NV entries. LTE works, not sure about AWS HSPA and not in a position to test.

Hello TEKHD,
I have a T889V, but my carrier up here is Virgin Mobile Canada, whose network is technically closer to AT&T's band-wise. DC-HSPA 42 on 850 and 1900 MHz with LTE on Band 4 (AWS).
Reason I got a T889V is because I also keep a T-Mobile SIM for stateside trips, it was a bit cheaper and it leaves the door open to switching to Videotron in addition to the "Big Three".
I first unlocked the phone using the ServiceMode menu method.
I backed up /efs, and this is where I made my first mistake. I know I've been ranting about this for a few days now, you need a proper Qualcomm NV backup.
I usually stick to the Canadian ROMs as they tend to remain closer to their international brethren than the US ones, and also because they don't require tethering fixes. In this case, the T889V ROM also allows switching network modes between GSM, WCDMA and GSM/WCDMA/LTE easily.
I did modify the CSC files to remove the <CscFeature_Setting_DisableNetworkMode>lte</CscFeature_Setting_DisableNetworkMode> line in /system/csc/others.xml and even went so far as making a customized VMC CSC and reapplied that to get all the other little carrier tweaks like FastDormancy. The line is cosmetic only, as I've had it show 4G in the network icon and still get LTE, otherwise it shows 3G, H, H+ and LTE on the T889V. The other place I've seen it have an effect is in the network settings where it'll show GSM/WCDMA/LTE instead of GSM/WCDMA.
I've used Odin before, I have a download jig (two paralleled leftover 620kOhm resistors and a Sparkfun breakout board) and I've tarred my own images before with Cygwin.
To get the necessary files, I downloaded the stock T889V, I317M (Canadian LTE Note II variant, the one that'd actually be sold by VMC if they ever do.) and T889 ROMs from Sammobile.
My initial attempt to flash the I317M modem through Odin (as a standalone image) gave a fail before the phone began the actual writing process, i. e. it transferred the radio image without any issues. Later experiments show that only the T889V modem tar flashes with Odin, the T889 one doesn't either. Same goes for the whole, original Sammobile images, the modem partitions fail if you're cross-flashing.
I then used CWM with an update zip sourced here on XDA that included a "flash_image" binary to flash the 317M LJ2 modem. I used it to prep T889 and 889V zips as well. Rebooted the phone, it connected and gave me LTE, network icon and all. The before and after speedtests went from 3.5 to 35 Mbps. I did check and my IMEI showed 0 instead of, well, my IMEI.
No big deal, or so I thought, I'll just restore /efs in CWM, reflash the T889V modem and carry on. NOT.
The phone immediately started bootlooping, and the only way I initially got it to stop was to flash an N7100 boot.img. The S-Pen didn't work, nor did any networking apart from wifi. Getting QPST to talk to the phone was a bust as well; the hen and the egg.
I tried different combinations and couldn't fix the problem. (My flash counter sits well over 20 now.)
I got another poster (deeznutz1977) to send me his T889 NV backup (sans IMEI) the other day. I later had the idea of reflashing the I317M modem again, which did not boot loop after all (there may have been a matter of wiping /cache and Dalvik cache at the right time).
This time dialcode *#7284#, selecting "Qualcomm USB Settings" then selecting "RNDIS + DM + MODEM" worked. I could get the programs talking with the phone. I inserted my IMEI in deeznutz1977's backup, wrote that to the phone and rebooted.
The phone doesn't bootloop anymore, my IMEI is back, as is service on my current carrier. Plus, this configuration still works with AWS HSPA. The one catch is that bootloops resume if I reflash the T889V modem through either CWM or Odin.
I made a few more speed tests before writing this and managed to get an average 45 Mbps down and 12 up along with a 40 ms ping.
Hope that answered a few of your questions.
Regards,
Darkshado

Wow... thank you for taking your time and explaining everything... really, thank you... so you managed to completely transform your T889V into a I317M... that's why it now bootloops if flashing the original T889V... as it would if you really had an I317M... is that right?
you don't have access to a sim with the t-mobile band in order to test for just a minute?
So... here is my story... maybe I can help here with the transformation of T889 to I317 and viceversa... (or maybe an hybrid modem like the one for the Note 1)
-> I have both the AT&T I317 and the T-Mobile T889...
-> I also have both with dual sim card adapters...
-> I also have 1 Unlimited everything T-Mobile sim card & 2 AT&T unlimited everything sim cards...
I want to be able to keep the T889 with 1 sim -> working LTE on AT&T and the 2nd sim -> ready for future T-Mobile LTE...both sims in the dual sim card adapter on the same phone of course (I also want to sell the I317) just keep one universal LTE Note 2
What can I do here? Willing to sacrifice whatever I need to... in order to accomplish my objective... This will help everyone here on both carriers...
As for now... I have noted that while navigating on both phones thru the service menu... the I317 says ENS: ENABLED and the T889 says ENS: DISABLED ... searched on google... no answer.... ENS stands for? Emergency Notification System? lol
Is there anything I can do here since I own both phones... that can sort things out in order to unlock the LTE feature on the Tmobile variant? or is that something we all just have to wait for the carrier to do via OTA? Is there any modded modem that can solve this? Your I317M modem... can it do something here for the T889?
On the pictures the one on the left is the I317 and on the right the T889... both with AT&T sims at the moment of the picture. If I go outside, the AT&T Note 2 will get 4G icon (LTE) and the T-Mobile Note 2 will stay in HSPA+...
I have MTP + ADB on both phones when using code *#7284# also... is there anything useful in this code besides unlocking phone? *#197328640# ??? Diagnostic mode here... *#0*# any more codes?

No LTE when using 919V with Rogers

Hi,
I just bought a Videotron locked SGH-M919V and purchased the unlock codes.
I am with Rogers, and since the unlock this phone works well for voice, but I can not get data to go faster than 3G.
In a place where i used to get 25+ mbps download with LTE I cant get more than 3.7 mbps.
When I look at the APNs, I have LTE tethering and Rogers LTE and Rogers LTE is selected.
In network mode I can only choose:
GSM/WCDMA
GSM only
WCDMA only
How can I get LTE speeds?
Thanks
Had the same issue on the BELL LTE network.
While searching on the web today, I found out two answers to your querry :
1 - Installing a little .apk application named "phone info" not available on the google store witch allow you to kinda force the usage of certain band (including LTE) on your SGH-M919V! See the attachement for the .apk application.
Once the application is installed on your SGH-M919V, open it
Select the first option (mine's in french, but it should be similar to Device Informations or Pheripherical Informations).
Scrool down to where you can choose the network bands or protocols from the menu.
On the Bell Network, "WCDMA prefered" was the default option, and changing it to "LTE/GSM auto (PRL) maked the phone switch between 3g and LTE speeds when available.
2 - Flashing the SGH-919's (non-v) modem.bin with odin. I tried this method, but it didn't worked as expected. The flashing wouldn't work as installed so I started to look for other answers. If someone found answers for this method, a tutorial would be greatly appreciated! (I followed theses instructione but it didnt worked for me :
I didn't wrote theses instructions, they are freely accessible on http://forum.xda-developers.com/showthread.php?t=2266101
1) Download the T-Mobile firmware from http://www.sammobile.com/firmwares/1/?model=SGH-M919&pcode=0#firmware
2) Find the file "modem.bin" and move it to another folder. This file should be about 50MB.
3) Put phone in download mode and plug in USB.
4) Start Odin software.
5) Select "phone" and select the "modem.bin" file.6) Only thing checked should be "Auto Reboot"
7) Hit Start
8) Let it reboot and after that you should be able to connect the LTE network.
The first method is the one that worked for me. Feel free to post any questions if unclear, i'll be glad to answer!

Might be Rogers oversaturated LTE Network.
The solution I found is this
For M919V flash the entire original stock rom of I337M from rogers, bell, or telus (3x) and reboot after each flash and then wipe cache and factory reset (with stock recovery). Your phone becomes I337M even on bootloader. Now you have LTE. To get AWS band, look for a thread that says how to enable AWS for I337/I337M . And now you have LTE + AWS
I recommand flashing Telus I337M 4.2.2 rom (it only has one telus bloated app) or the Bell one (4 bell apps). Rogers is the worse rom to flash lol
I've experimented and tested it, thus it definitely works!
That solution seems to work for M919V models only.

[Q] Only finds AT&T network

PLEASE HELP
My Galaxy Note 2 (SGH-T889) has been flashed with mr Robinson's "root66_TMO_T889UVUCMK7_2.7z" (baseband T889UVUCMK7)
The phone boots fine to version 4.3. I have a T mobile sim card in it
Device info is
Kernel version 3..031-2085660
Build #: JSS15J.T889UVUCMK7
Network mode is set to LTE/WCDMA/GSM (auto connect)
When I search for all available networks i only get AT&T (I need T mobile)
I have another Galaxy Note 2 (SGH-T889) flashed with the same mr Robinson's. Same settings, when I search networks it finds them all (T mobile, AT&T)
Is the phone that only get's AT&T network locked to AT&T? or could there be other reasons (it is an SGH-T889)
I was reading that if you flash T889UVALJ1 (4.1.1) you can unlock the phone (although I don't know if it is locked, how can you find out?)
I tried loading it but I think the 4.3 boot loader stopped it from working.
Should I get a custom boot loader on the phone? is so how do I do this (I read something about goo manager?)
Please provide details as I am a newbie.
is there something else I should be looking at or doing?

If it were an att note 2 it would not be the SGH-T889 it would be i317. What does your APN settings show? if you are on the 4.3 bootloader I don't think you can use odin to go back to uvalj1. if you want to unlock I have heard of people only flashing the uvalj1 modem and having success. Custom bootloader? Do you mean custom recovery? you can download that from goo manager. Do you not have a recovery installed (CWM, TWRP)?

Install the app and open it. Tap menu then hit Install OpenRecoveryScript. Tap Yes. Verify that the filename displays your device's code name and hit Yes. The file will download and your device will reboot and install the recovery automatically. source: http://teamw.in/project/twrp2/123
once you have the recovery you can flash the modem
I have not heard of locking a tmobile phone to att but I could be wrong. Are you not getting service at all?

Since AT&T is the only network recognized and I have t-mobile service I have no voice or data service on this phone. My other SGH-T899 which is flashed exactly the exact same recognizes other networks as well as AT&T

Not to be goofy, what is the model number printed on the sticker under the battery?
When you boot into download mode, what model does it show on the screen?
Edit:
Go into the dialer. Dial *#2263# and tell us what setting the asterisk is next to, automatic is the preferred one. Check and see if you can tell which bands are selected in the various GSM/WCDMA/LTE selections. I don't think you can, but it couldn't hurt to look.

[Q] Unlocking phone

Hey guys,
Looking for some help here. For what ever reason the unlock code that T-Mobile sent me does not work - resulting in T-Mobile giving me a $200 credit which is nice, but I would still like to get my phone working with ATT.
I have downgraded to 4.1.1 to do the free unlock methodhttp://forum.xda-developers.com/showthread.php?p=34661189, but my baseband is still at UVUCMK7. I have tried rebooting the phone into recovery mode and installing Stock-TMO-T889UVALK8-Kernel.zip but although it says it was successful, the baseband is not changed.
Any ideas? Help?
Thanks

What happens when you put in an AT&T SIM?

When I follow the unlock code it works all the way through to where they say go back to NETWORK LOCK and choose option 4. Option 4 is not there.
When I reboot with the ATT sim it simply asks me for the network unlock code.
So Baseband is still: UVUCMK7, Android version is 4.1.1, Kernel is 3.0.31-598701

Once the device is unlocked you will need to go back to an LTE enabled modem. Your previous radio would be your most likely solution.

I have a T-mobile Samsung Note 2 (SGH-T889), that I'm trying to unlock. I have downloaded the file from the links listed here on XDA. I have already downloaded Odin307 and the Samsung USB driver. My problem is Everytime I put connect the phone, open Odin, and put the phone in download mode and add the file to Odin then while it says Please Wait.. (just a few seconds after adding the file) then Odin has Not Responding come across the top. I have deleted all the things I downloaded and re-downloaded them after it did that a few times and its still doing it. I have tried the downloads from different sites and it doesn't seem to make a difference.
Can Anyone Please Help me?
Thanks to Anyone who will take the time to help me.

[Q] Unable to connect 3G using I317UCUCNJ1 Baseband (AT&T SGH-317 in Thailand)

Any assistance troubleshooting my issue is greatly appreciated.
Background:
I have AT&T SGH-317. It was stock/unlocked/unrooted. I traveled to Thailand and signed up with TrueMove to get new SIM card to use while in that country. Upon inserting the new SIM card and powering device up, I receive Unlock prompt. I contacted AT&T to get unlock code, but they refused to give me one because I'm still under contract (even though it's for another phone and my SGH-317 is already paid for).
I took the phone to a shop (MBK) to get it unlocked. But they were not able to do it without rooting the device. I mention this because I don't know what method they used to unlock the device. So at that time, I had unlocked/rooted device running Stock Android 4.4.2 Baseband I317UCUCNJ1. I installed the new SIM card but not able to connect to 3G, H+. I changed Network Mode to WCDMA only and adjusted APN to TrueMove settings, still no 3G, H+ connectivity.
I came to this forum to search for solutions and have done the following:
1. Flashed ROM to DN3(Ditto Note 3) ROM using Odin 3.07 and openrecovery-twrp-2.8.0.0-t0lteatt.img.tar
2. Set Network Mode to WCDMA only
3. Set APN to TrueMove parameters
I tried to Flash modem file suggested in One-Stop Shop Thread but failed miserably. I tried both I317UCUCNE5 and CWM-I317UCUCNJ1. Both files were .zip, so I unarchived and then rearchived using 7Zip to make .tar file so Odin would be able to utilize. Both attempts failed when I tried to flash.
I checked with my brother who has the same phone to see what modem he is using since his device works. He is using I317UCBMK6 baseband. I tried to download that baseband from link provided in One-Stop Shop thread, but it's an .exe and my virus protection software flagged it as virus and immediately deleted it off my computer.
The Ask:
1. Appreciate it if anyone is able to provide I317UCBMK6 baseband as .zip or .tar
2. Inform me on why the other two basebands failed flash and assist with proper methodology
3. Inform me on best option to solve my issue of not being able to connect 3G, H+ on my SGH-317 running DN3(Ditto Note 3) ROM with current baseband I317UCUCNJ1.
Thank you, community!
