900T with ATT - Where is the ATT modem ? - Galaxy S 5 Q&A, Help & Troubleshooting

Hello,
I have a 900T that I am using on ATT network.
Where is the ATT modem that I can install?
It currently has the T-Mobile NK2 baseband.
thanks haeffnkr

You don't need to install an att modem. Just update the APN and you're good to go (assuming your phone is unlocked)

Hi,
Yes I am getting connected to the ATT network with tmobile modems but....
I am getting download speeds under what my ATT S4 was doing and my signal drops from time to time.
I would really like to use the ATT modem and see what difference it makes.
Does anyone have a link the the ATT S5 modems?
thanks haeffnkr

Hello,
You can either extract them from the stock ROM or search the SM-G900A forums.
I did a quick search and got this
http://forum.xda-developers.com/showthread.php?t=2868904

thanks I did not find that when I searched.
Any chance you can find the - G900AUCU2AOA1 version
thanks again haeffnkr

[Q] Flashing roms

Hi,
I have SGH-M919V and its unlocked.
I am on Bell and want to use LTE. But this model has LTE disabled. when i enable it, cant make phone calls.
I cant seem to flash T mobile modem via odin. there is this secure boot issue. the AUTH: Fails.
I was thinking of installing Bell SGH-I337M rom on my phone. Is that possible? If so, how do I go about doing it?
Thanks!
Since you have a T-Mobile variant you should ask in the sgs4 tmobile forum...
However your problem with lte/phonecalls is likely just an APN issue
To further assist we would need to know which carrier you are using the device on

Hey. thank you for the reply, I really appreciate it.
I've been asking a lot there. No one is answering.
Please help me out, please.
My phone is Canadian variant, originally from WindMobile - SGH-m919V. Wind uses Tmobile freq. = 1700/2100 (AWS) only. No LTE.
I got it unlocked two days ago, and switched over to Bell carrier. Bell uses the other freq and LTE.
When I do force LTE by *#2263# - and enable all LTE, i get LTE speeds. But NO calling or texting. this is with the original Windmobile stock rom. No modification. No root.
I tried to flash Tmobile modem via odin 3.07, didnt work. I used the phone button to load the modem.bin. It gave me AUTH: Fail, secure check fail.
I agree, wrong forum, but we are here to please....
if you have a M919V then you would flash the rom you want, before you boot, flash a tmo m919V kernel, it will boot, manually add your apn settings for your device, it will work with data/wifi/calls.
Good luck....
Hi, im sorry for posting in this forum.
so if I want to flash the bell rom - I337M stock original rom , how do I flash it without booting??
And then how would I flash the tmobile kernel so then I can boot??
I dont mind keeping my current rom - wind stock. But, I want to be able to use LTE like how tmobile has pentaband 3g plus lte.
:/ .

Go to sammobile.com, search for your firmware, download and extract modem.bin from there. That's the file you need.

for example, firmware for Hungary T-Mobile is here: http://www.sammobile.com/firmwares/1/?model=SM-N9005&pcode=TMH#firmware
download and extract modem.bin from there. Then you can make this file flashable by Odin.
Not as easy as it looked. You have to get your phone to read the bands that T-Mobile is working with. There is a bunch of us, even a bounty out for it! Trying to get the N9005 version to read At&t LTE bands! Sure you can flash the modem but unsure if it'll work. Keep us updated though if you do flash and receive LTE service!

anybody know if there have been any successes getting lte working on tmobile / at&t on the n9005 via modem flash?

From what I can gather, due to others having same issues, it hasn't been possible (yet) one user notably @PatienceWithin had to sell his 9005 and get an 900A
just polling the community to see if anybody has figured it out yet or has gotten any closer... I'd really rather not resell my phone and buy a 900t but i really want lte... the baseband on these things are pure software, are the same baseband hardware as the tmo and att versions, there's no reason why it can't support the required bands. ugh!

[Q] SM-9006v - Using on t-mobile

Hi,
I just purchased a Galaxy s5 sm-g9006v. This is the chinese unicon Samsung galaxy s5. It's unlocked.
I have a t-mobile sim. The phone works fine but the only problem is that it's only running 2g speeds! and i've been reading and i think it's a problem with the bands the phone is working on.
I've also been reading about changing the firm-ware modem but I need a little help.
My question :
Can I change the bands that my phone is using to t-mobile compatible bands to run hspa+ or lte or 4g ?
If so, is it as simple as flashing flashing t-mobile firmware from sammobile (sm-g900t) to my phone via odin?
And if I can fix it without having to flash the whole original firmware by just flashing the modem (which is 5mb), where can i get the modem for that firmware and how do I flash it alone ?
Thank you

tmobile modem on n910c

i know n910C is not for USA, but here I am using N910C in USA on Tmobile network
and i am having issue with weak network/signal at many places
and i was wondering if there is a way i can install Tmobile modem/bootloader on N910C.
I already downloaded tmobile modem and bootloader and tried to install using odin,
but it fails everytime.
any help please
thanks
i have an n910H. by default, its set on 3g, metropcs lte. then ill just register it to a tmobile network. i guess my version cant get lte so the highest i get is H+. which is still as fast as lte, at least to me. and im using tmobile.
You cannot flash tmobile modem or bootloader only thing to do is buy a tmobile branded phone

G930A APN.config file.

Hello all, I'm using a G930T with the Verizon Stang ROM on ATT network. Everything is running great except my Data signal.
I'm only getting "H" and rarely "H+".
I changed my APN settings to ATT.
I used ODIN to flash the TMobile PK1 Modem which helped but not completely fixed it.
The OP of the Stang thread said that I need an ATT "apn.config" file from an ATT ROM and that I would also need to change the permission of it to "0644"
Could anyone help me out or point me in the right direction?
