[Q] Which T-mobile Rom Wifi Calling for AT&T S4? - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hi - I have bought an AT&T S4 with the following version:
4.2.2
I337UCUAMDL
I did the XDA method for unlock, it worked great. Then did super root and it worked, also installed TWRP. I've also done the AWS band unlock.
Now, the biggest challenge, which rom do I install for the stock T-mobile features? Mainly I just want a stable rom with T-mobile wifi calling.
I would appreciate the help.
Thanks!

Read the OPs of the Roms in the T-Mobile S4 section.

You need to flash a hybrid radio unless you never updated past stock 4.2.1,
newer radioes have the code disabled since it hasnt been approved by the FCC for LTE

The Nexus 4 does not support all of the AT&T LTE bands. It lacks the most commonly used LTE bands for AT&T and therefore can only be used in a couple of cities. If you do live in one of those cities, you need to unlock the bootloader and flash a hybrid radio.
OK I've been reading and I'm a little confused is there a solid working root and bootloader unlock for 4.4.2 ?

If I root and unlock can I flash any radio even if I'm on 4.4.2

You can flash any baseband (aka radio) you want but, in order for LTE to work, you will need to flash a hybrid radio. For 4.4.2, you would need radio version .98 or .97
There was a recently released app that makes installing or changing either the hybrid or stock radios extremely easy. I used to use the manual method until this came along:

As was also mentioned, AT&T Band 4 is not available in too many areas, so don't be surprised if you never get LTE.

Tmo 4.4.4 stock rom on 1337m?

Is there a reason you cannot install stock T-Mobile 4.4.4 on Non ATT 1337m?
I tried to install stock T-Mobile 4.4.4 on virgin mobile 1337m but it generates an error.
I thought the T-Mobile S4 was similar to Canadian and South American S4
Thanks in advance
The issue is the updated radio not sure if it'll work with the Canadian version. I installed but got no signal

Interesting...In theory It should work. If you get the TMobile S4 unlocked it will work anywhere in the world.
I could not even get it to install

[Q] NOOB trying to unlock AT&T S4

I have an AT&T Galaxy S 4, SGH-I337 running Android 4.4.2 and I want to unlock it. I haven't had any luck with doing it my self through the Service Menu, I guess due to KitKat.
My question is If I use Towelroot to root my phone, will I be able to unlock my phone and use on T-Mobile?
Thanks for all the great stuff on your site!
Have you tried this? It's in the general forum

Install Verizon ROMs on Sprint S5! [Guide]

Did you know you can install Verizon S5 ROMs on Sprint S5? (This is for TouchWiz ROMs)
This should work for most Verizon S5 ROMs on Sprint S5. (Also works for S4, S3, and Note 3)
First, make sure you have a bootloader that supports the correct Android version. (e.g. installing 4.4.4 Verizon S5 ROM may require you to have Sprint 4.4.4 bootloader on your Sprint S5, otherwise may not boot.)
Currently I have tested 4.4.2 Verizon Roms on Sprint S5 with 4.4.2 bootloader but haven't tested Verizon 4.4.4 ROMs, will update when I do.
Second, install the Verizon S5 ROM normally with factory reset. It should install fine.
Third, Once booted, set the APN to Sprint 4G LTE as shown here:
http://highonandroid.com/sprint-4g-lte-apn/
Fourth, that will get everything working except MMS sending. To fix MMS sending, just use 8SMS app from Play Store and enable 8SMS as default SMS messaging app.
Having trouble?

What's the best Verizon rom?

That is like asking what is the best car. Go drive them and decide for yourself.
This is a really cool find for those flash-a-holics that have beat all the roms for their devices to death and needed more options. Thumbs up my man!!!
Thanks for this tutorial. I tried it and right now I have a fully functional Verizon rom on my g900p.

I assume this would render Spark useless, correct?
I dont think that would be the case since your reinstalling your sprint apn settings
Can I install a Verizon 4.4.4 rom?

quite Rude tbh, there is always that one ROM that is the most popular and usually, that is the best one.. Sooo
I have a sprint variant note 3. So far this method has worked for all variants of the note 3 for me. I have flashed Verizon, Tmobile, AT&T Note 3 roms and the apn settings change works on all. On some roms i have found that the apn settings change will not stick. To get mms to send and receive text and pictures on those that do, all you have to do is pull the mms apk from your carriers stock rom and replace the mms apk of whatever said rom you have flashed with it.
Nfl
Does flashing the Verizon rom allow the NFL app that's exclusively for Verizon subscribers to work??
I upgraded my bootloader to 4.4.4 and I flashed Verizon and works like it says ...rickshaw romV1

If u are in 4.4.2 flash 4.4.2 rooms if not 4.4.4 flash 4.4.4 roms
Looks like we can do tmobile aswell testing now will test other carriers aswell I flashed rom then flashed kts kernel reboot
