Att radio/ Modem for Tmobile note 3

Any devs here who can rip and make a flashable zip of the radio or modem from ATT rom.
I am on tmobile device and noticing that LTE signal is low compared to my other devices.
Thanks

I too would like to try this. I asked about flashing a note 2 ATT modem but I was told that it would more than likely soft brick my phone or worst case hard brick the phone. I've read plenty of other threads where people are flashing different carriers modems on multiple devices, mostly the S3 though and some on the note 1. On the Note 1 I remember a lot of people flashing the T-Mobile Blaze modem on the ATT phone.

The MJ6 update has some Universal CSC changes. I would suggest clean flashing, but make a backup and dirty flash and let us know what you get. Give the phone 15 to 30 as a habit, to make sure there are no issues. I've found out that the phone can seem like it's working then after 15 min or so will start crashing or bootlooping. .
As for ATT Ril, i'll help Miscom look for that.
Anybody has stock file for ATT and of course is on att. send me the following files and i will make a flashable ril
System/lib:
libaudio-ril.so
libreference-ril.so
libril.so
libril-qcril-hook-oem.so
librilutils.so
libsec-ril.so
libsecril-client.so

i'm getting very poor LTE speeds, overheating, etc.. and i'm sure it's something related to the ROM/modem/etc.
THANKS

Nope not able to.... But I have not felt the need for it

Tmobile rom on AT&T Note 3?

Is this possible to install a tmobile stock rom on the at&t note 3 or will the locked bootloader prevent this? just curious as i'm gonna be moving to tmobile for the unlimited LTE and would like to use the stock apps as well with it. Does anybody know if this is possible? I looked around a little bit and couldn't find any information on doing this.

1. This should be in the help section
2. I've flashed verizon roms on my note 3 without a problem so it's possible. All you'll have to do is update your APN settings. It can't hurt to try it, that's the point of safestrap!

Yeah I'm not rooted so was wondering if the tmobile rom via Odin would fail or not

How to downgrade from 4.4.4 (NJ5) to 4.4.2 (NC2)? [AT&T Note 3 for T-Mobile]

Hey guys,
Upon reading through the threads, I wasn't able to find specifics to what I'm looking for.... it's apparent that the support has stopped for this issue, which I completely understand. Any help would be greatly appreciated.
I have an unlocked ATT Note 3 on (NJ5) to be used on T-Mobile.
I'm wanting to downgrade from 4.4.4 to 4.4.2 to get back to (NC2).
Can someone confirm the following: (Please add to it if I'm missing something)
Odin ATT 4.4.2 (NC2) - Anyone have the direct link?
Root - Best method?
Safestrap work around? Is this the correct thread? How about this?
Planning to flash ATT FireKat (TouchWiz based) ROM....
From my understanding:
I only have one shot at this, therefore, I want to make sure that all my ducks are in a row before doing this as a "mistake," isn't an option right? I only have one shot at this or Hard brick yes?
Questions:
After successfully doing all this, with the correct TM APN settings, will the ATT phone be able to use all TM's bands? LTE 1700, Band 4 etc....
What are any drawbacks of using the ATT N3 on TM, if any? (I'll be happy with 4.4.2 so no worries on any fancy updates.)
The phones currently unlocked right now. Will doing the steps above lock the phone back up?
Is this all worth it or should I just sell the ATT N3 and buy a TM branded one?
Is there anything I'm missing?
Thanks in advance!
* I hope this post also helps anyone in the future that's in the same boat as I am.

this will give you 100% stock nc2.
Best way to root is with towel root.
with safestrap you do not need a workaround as it works perfect on nc2 you only need to do a workaround if you would like to go to 4.4.4...And for the record I've done a lot of flashing of random stuff that came from here and I did myself and I'm yet to hard brick or come from a point of no return.
all those t-mobile questions I can't answer cause t-mobile is crap in my area..
Hope this helps!

Thanks a bunch! I really appreciate it.
To confirm:
From a dead stop (the state my phone is at right now on NJ5)...
1. Odin NC2. (Which one specifically shall I download? I see a bunch of different links.)
2. Towel Root.
3. Put the TM Sim in...add APN's...
4. Flash ROM if desired...
5. Good to go?

Just need these 4... and if you want to rom you need to install busy box and safestrap after you root with towel root. Then yea should be good to go!

Gotcha. Thanks!
Oh and would you happen to know if the ATT device has the 1700 band (band 4) to support TM's LTE? I remember with the older devices ATT branded phones didn't have the 1700 build in, but now I'm thinking it might be different....hhmm
Also, it is unlocked right now...will the phone lock itself after all this?

Not sure but I think there is some that use att note 3 on t-mobile and works fine I'm guessing... and personally never unlocked a phone for use elsewhere as I been with att for like 10 years lol... but I really don't see it locking it personally...

Help on using 4G LTE in Pakistan
I have just received my AT&T Samsung Note 3 model SM N900A and am using it in Pakistan with warid network. I received the sim unlock code from AT&T. Warid is giving us 4G LTE service but my cell does not work on it. Since warid is not giving 3G service, my cell just connects using edge which is very slow. I actually bought Note 3 for 4G LTE but due to some reason its not working. The carrier people have no answer except that my set is not supported by their system. Can you kindly help? My set is not rooted.
Warid 4G LTE is working on 1800Mhz FDD Band 3 which is supported by my set. Other device parameters are as below:
Baseband version N900AUCUBMJ5
kERNEL VERSION 3.4.0-1625098
[email protected] #1
build JSS15J.N900AUCUBMJ5
Android version 4.3
And I would also like to know if I can update my set to newer android version or not?
Awaiting your positive response.

Question, are these files also downgrade the modem firmware to match the 4.4.2 ROM?
The reason I want to downgrade to 4.4.2, is to fix the GPS signal issue we all AT&T Note 3 owners having after the 4.4.4 update. Does anyone downgraded to 4.4.2 and GPS issues fixed?

Sprint Flex to ATT, then to Tmobile issue

Hi guys, Have a question;
I took a free LS995 (sprint) and modded per the forum and turned on GSM. Then I flashed the ATTSPRINT rom and edited the APN to get it to work on TMOBILE. The ATTSPRINT rom is on 4.2.2. I got curious and flashed the modded TMOBILE rom from the forums (4.4.2) over the ATT rom. For some reason, now I can't make calls. Checking the Mobile networks, the setting don't look right, but I can't change them.
Just looking for some direction while I search...thx in advance.

Use *#*#4636#*#*
3845#*ur model#
5457#* ur model#
OK, I can get into these menus, but what do I need to change?

Unlocked S8 -> Tmobile

Hello, I'm a tmobile customer that just purchased an unlocked galaxy s8 from the Samsung website. I'm wondering if going to the store and getting the tmobile firmware on it installed is really necessary. I mainly want to do this because of the software updates, but then I thought the the unlocked version might get updates from a different source? Am I right? I'm sorry about this being such a general question, but I just want to do what's best for my new phone. Would you recommend me installing this firmware? Or should I just keep the stock unlocked firmware it came with? Are there any drawbacks associated with not installing the tmobile firmware on it?
EDIT:
To start, will Tmobile even do this in the first place? I'm totally clueless whether they offer installing their software on customer phones or not.
Thank you.

Hi there. Unfortunately, you are going to be really hard pressed to find a T-Mobile rep anywhere that could/would flash firmware w/ Odin. Not saying that there aren't some reps out their that don't know about this stuff (there are a lot that really have no clue though), but this is well outside of what most of them are trained for, plus Odin is only supposed to be used by Samsung. Also, historically (at least the last couple of years), for whatever reason Samsung's unlocked US models have been getting updates slower than the carrier versions, which really doesn't make any sense because there is less to go through to get them updated. That being said, there are several threads in the T-Mobile S8 forum here as well as the general S8 forum dedicated to carrier switching, which can guide you in turning your unlocked model into a T-Mobile model, for all intents and purposes.

The guy that replied first is really correct! T-Mobile store won't flash any phone, don't go beyond simple troubleshooting. It is easier to fly to Mars, than talk about flashing a device with rep. I do hope there are some T-Mobile reps that do really know about flashing, but I just haven't seen one yet.
I am with Unlocked S8 and use it on T-Mobile. I don't have any signal specific issues for example and features such as WiFi Calling, Band 12 and VoLTE all work well. There are few thing that flashing to T-Mobile firmware could give you:
Video calling(to specific phones only)
Advanced Messaging(believe other phone needs to support it)
DIGITS service will be built into the phone dialer.
I was also debating about doing it, but all 3 mentioned features are not wildly available and don't work across all devices and networks. On top of that you will get few T-Mobile apps pre-installed + Lookout app + T-Mobile logo when booting up the phone.
We can flash practically anytime we want, so I would suggest you to wait and see how Samsung will treat unlocked devices and how fast updates will arrive. If T-Mobile will do them much better than Samsung, then I will flash myself or when those 3 features above will work across all devices.

Sorry for reviving this thread, but my unlocked s8 gets slower upload and download speeds than my friends tmobile s8, we are both in NYC and he's getting 100mbps and I'm getting 30-40mbps. I assume they also have specific settings hardbaked in their rom that allows for optimized carrier usage?

the t mobile firmware comes with 4x4 MIMO and 256QAM. which leads to better signal and faster download speeds.

Can I flash just the modem or CSC to get the benefits without flashing the whole tmobile rom?

This is a question I'd like the answer to. I'd like to keep all the Samsung default software features but get RCS, which is the most important thing, and one of the main reasons I'm still using my LG G6.

i think you'll need the whole firmware to be able to use RCS and the tmob features. i personally think the tmob firmware is better since it has 4x4 MIMO and 256QAM enabled. so better signal and service

I don't care about any of that. I value the Samsung unbranded experience more. All I want from the Tmo FW is RCS.
Alternately, if they ever support it using the unlocked S8 FW, i'll switch back to my S8 in a heartbeat. My G6 seems to get tons better battery life anyway for some reason.

Can someone provide a link to a thread for flashing the Unlocked s8 to T-Mobile?
Thanks.

There are multiple sections, but I believe you need to look under: Flashing Standard Firmware, but do ask, just in case.

I believe you have to use the "flashing unlocked firmware" because the prince's version of the ODIN will bypass the ROM checksum and let you flash any variant you want. if you use the normal ODIN and you are going from unlocked to t-mobile (950U1 to 950U) ROM it will fail.
I used to be on the unlocked but now I'm running t-mobile rom to have multi-line baked in to the native dialer. and my service provider SW ver. shows TMB/TMB/XAA
All is good and I'm happy with the ROM after few days the battery life seems the same as the unlocked version.

i just want to know if i can keep the bloatware free and just flash the modem from tmobile firmware.
i just want wifi calling, volte, 4x4 MIMO and 256QAM. i dont care much for the multi line feature cause not useful on my end and idk about rcs because the person on the other end needs to have it and i dont really see it as useful.
lol s7 bloatware free firmware was so easy to flash compared to this xD
im running the att variant but im sure all the hardware is the same. so i dont see why the unlocked firmware wouldnt support this out of the box.

When I had my S7 Edge I was able to mix and match different ROM with different modem files ie I would be on the unlocked ROM with the tmobile modem and was able to use the unlocked firmware with t-mobile radios. This is what you want but I have not tried it with the my S8 you can try if it dont work use the prince's ODIN to take you back to stock.

Isn't "flashing unlocked firmware" means that you have a carrier provided phone and want to flash unlocked firmware on it?

Correct, but it also works the other way around. Anytime you want to change variant you must use the modified version of ODIN as it bypass the checksum or the flash will fail.

Thanks Peeps!
