Yes, you can enable LTE into SGH-M919V. You need to find the T-Mobile's modem (M919UVUAMDL or M919UVUAMDB) and flash it. But first: did you try force LTE in your S4?
To do this just dialing *#197328640# and then select UMTS -> Debug Screen -> Phone Control -> Network Control -> Band Selection -> LTE Band Preference -> LTE B4 -> LTE B4 again to confirm. Then you need to go back to the previous screen. If you see a [*] after LTE B4 the device has support. The Band 7 (LTE B7) should also works in Canada and you could try select it onto the same process.
Please, let me know if it works for you!

It works!!!

Hey, my friend just got his SGH-M919V and is using it with Bell LTE!!! Here are the steps:
1) Download the T-Mobile firmware from http://www.sammobile.com/firmwares/1/?model=SGH-M919&pcode=0#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.

I did the steps you provided, but I got this:
<ID:0/003> Receive Response from boot-loader
<ID:0/003> FAIL! (Auth)
I know this isn't my thread. But, i am having similar problem.
I am using Odin 3.07.

my phone can enter any service code
how to fix even to check the imei code

I also have the same problem. My Galaxy S4 (SGH-M919v, Open line) doesn't have an LTE option in the network mode settings. It also has a sticker on the phone saying 4G LTE
I even tried updating to Android 5.0 Lollipop from Android Kitkat 4.4.2 (over-the-air) and still the LTE option isn't present. I searched through the internet about S4 not having the LTE function but only for different Galaxy S4 (i9505?)

dial *#2263*
pick automatic. this turns on LTE if its available. I'm on Koodo network. its usually 3G, but depends where I am.

dial *#2263# instead of *#2263*

BTW you should post in Galaxy Note 2 Q&A forum ( use xda device search engine to locate it)
A modem change might give you results only after you have checked your APN ,
Quick Guide
First Check your settings > about phone > status > your phone number ( IF UNKNOWN )
You won't be able to send SMS by any third party sms apps or Have a Network connection
Solution :-
You need to edit that "unknown" number to your phone number, by putting your SIM card on any old phone that has a "my number/owner number" option, (most old phones do). Edit and save it to the proper phone format as your Sim Card number (Example: +63913XXXXXXX). Now put the SIM back to M110S, to solve this problem.
Than check your system settings, in Settings > Wireless & Networks > Mobile Networks > Access Point Names.(APN) as provided by your Network provider . If your Apn is not set, you wont be able to have data connection, so set it first
If still no data connection, Common Trick is to toggle WIFI and Airplane mode or
1. Turn ON WIFI
2. Set the phone to Flight Mode
3. Power down the phone for a few Minutes
4. Power it back up
5. Turn OFF flight mode
6. Turn OFF WIFI
Should get Data back

Add GSM and LTE bands in Brazil

I've spent 3 days trying to enable GSM and LTE bands in my Swift following this guide from here. But when I try to use the QPST, the software does not recognize my device.
Does anyone knows the secret code to enter in the USB Settings? I've tried a lot of them but without success.
My steps were:
Unlock the OEM - check
Install CyanogemMOD 13 (6.0.1. Marshmallow) - check
Enable Developer Options and enable debugging and Root Access (I couldnt install SuperSU coz I got bootloop twice) - check
Access to USB Settings to change from AP to CP - uncheck
Does anybody knows how to proceed?
I'm from Brazil and I really need to add new bands to get a better signal reception for GSM and the right band for LTE (700Mhz).

Anyone?
I just need the secret code to enable the usb settings.

The problem was my carrier and not the phone.
I've changed the carrier and boom... 4G working nicely.

cannot get LTE communication with S4mini plus (i9195i)

Hello
Here is my issue: I buy a second hand S4 mini plus (i9195i - serrannoveltexx) for its compact size and by considering the simple usage I make of my phone. So far I do not use so much data so I don't care about used network, but recently I start using more data and I notice I never get LTE. I change carrier because I was thinking LTE-cover was the problem, but not. I still have no LTE. So below, is more or less everything I tested:
at beginning, I was few months on stockrom. Then I go to LineageOs 14.1 (thank to dev for the work). In both case I'm almost sure I had no LTE (I checked APN and 4g/3g/2g enable in network menu. And I start to check LTE-cover of each carrier . And I very start to check band used by the different carrier).
I change carrier and I check APN once more : still no LTE.
I come back to stockrom (just in case) : still no LTE
I switch SIM card : my sim card in Oneplus One get LTE and sim-card of my friend do not get LTE with my phone. (So I try copying manually the exact same APN : not working)
I try to flash old stockrom and let OTA update make the work : no LTE
I make necessary to have CSC=XEF as I am in France.
I try flash with pit-file and re-partition.
At the end, the best thing I succes to get was H+ (and for some reason I have it when I clear and restore the NV in 'service menu'), so :
-I contact samsung and they recommend me to go to one of their after-sales office.
-I contact my seller and he tells me that LTE works in germany.
Does someone has an idea how to solve this issue ? something that could block LTE ?
Next step I have in mind :
-I read some topic where double-flash within wipe and clear factory could help (but I have the feeling that will not work because it is more or less what have done to change CSC)
-I would check the activated LTE bands (but in 'service menu', I find a LTE band hexa-value that meet with explanation of binary description (another thread in XDA - thanks to people who write this tuto))
-I am considering go back to LineageOS but 15.
-I am considering to change LTE antenna (this is part of middle frame - I notice if I enable Data when i have 'service menu' opened, the phone seems to looking for LTE first, so I am not sure this is only SW problem ... do you think it is possible that only LTE part of such a SystemOnChip could die ?)
Thank by advance for your help
Best regards

Some older Samsungs eg Note 1 had reception problems due to poor connection (possibly oxidised contacts) that could be fixed by simply tightening the screw a fraction that secures the pcb or antenna so it was grounded (from memory) properly, though of course it could be your actual antenna that has failed. (possible cleaning contacts might be worth a shot if tweaking screw doesn't fix)
(or modem/baseband issue if software, try flash again or try another version, backup your baseband radio settings first with twrp or an app)
edit: also try reset network settings before paying for new antenna (edit: though suppose flash with pit etc should have done this)

Hello,
Some news on the topic:
I try to tighten the screw and I also try to clean LTE antenna contacts : I use very very thin sandpaper (usually used to polish) to be sure there is no oxidation
I also make the mistake to erase all EFSs and EFS_Backup
Reminder : in service menu (*#0011#), then 'UE Setting & Info' / 'Setting' / 'System' / 'NV backup test' / 'Erase all EFS 1/2/3' => So never do this if you have no backup
After this, I lost my IMEI... no way to restore it with IMEI tool... What a pity because I was hoping to only set my IMEI in order to test with completely clear EFS. Finally I restore my IMEI thank to my very first TWRP backup (thank to TWRP team that it works for me because it seems not always the case)
I try 3 times consecutive reset factory : 2 in recovery and 1 in settings.
I try to activate new LTE band but it seems that as I am in StockRom, update is not properly done.
In fact just after the work with QSPT and QXDM, I can find the nez band in service menu (*#0011#), then 'UE Setting & Info' / 'Setting' / 'System' / 'LTE band & CA combination. but after reboot I lose it. Probably I'll make the work one more time after coming back to LineageOS.
One last thing I want to try is going in front of 4G antenna and check signal power seen by the phone but I'm thinking this is not the true problem. I explain:
service menu (*#0011#) start to show Basic network information and if I force LTE_only (in service menu), I can observe these information. strange thing I see are sometime state goes to 'TAU_init' (and also 'deregistr' or 'register'). Some other time MCC-MNC goes to 151515-1515. I have the feeling the phone is trying to connect but something goes wrong and I do not know what...
if someone has an idea, I am still looking for.
Best regards
