Hi there XDA,
First of all, I don't claim to be a developer nor I am here to plagiarize/steal/uncredit those developers and providers.
Therefore, this post is to provide you with the latest UNLOCKED SM-G935U Stock Firmware for
users running the T-MOBILE variant (SM-G935T)
There were many comments on threads as to when the firmware would update, and finally is here!
Note: I DO NOT TAKE CREDIT FOR THIS, I DID NOT CREATE THIS OR STOLE FROM ANYBODY. THE INFORMATION PROVIDED LINKS DIRECTLY TO SAMSUNG's OFFICIAL FIRMWARE WEBSITE "SAMMOBILE".
Note to the Community: This latest version is confirmed to have ISSUES with ROOT. After successful root and/or XPOSED, Wi-Fi connection, overall lag, and heating issues are present. So it is up to you if you decide to root or not.
Note to Admin/Moderators: IF YOU FEEL THIS THREAD IS NOT APPROPIATE OR IF YOU WANT TO ELIMINATE THIS THREAD, FEEL FREE TO DO IT. My intention is just to provide the community with this update for the SM-G935U (T-MOBILE) Firmware as quick as possible for those in need and for those pioneering fellas.
As soon as I am done setting up, I will surely provide you with any insight/features added to this update.
Happy developing...
RECENT UPDATES ON ROOT PERFORMANCE/STABILITY [Jan.30.2017]: This 4APL4 Variant INDEED works with the root method by @Mastajeff, I can't find any issues at all. I personally believe that this Firmware version without root works even better for whatever your needs.
*** BASED ON PERSONAL USE AND RECENT DOWNGRADE TO STOCK G935U###4API3, I ENDED UP HAVING BETTER PERFORMANCE, BATTERY LIFE, AND STABILITY WITHOUT ROOT. I JUST WENT ON TO DISABLE COUPLE SYSTEM APPS WITH EZ DISABLER. I NOTICED BETTER RESULTS, PERFORMANCE, AND STABILITY USING ROOT ON THE PREVIOUS #4API3 FIRMWARE VERSION. (THIS IS JUST MY OPINION BASED ON RECENT UPDATE I DID, BUT IT IS ALWAYS YOUR CHOICE TO WORK ON)

I am on previous U firmware API3. Is there a way to upgrade to this without losing data?
Thanks,
Hello my friend, of course you can upgrade without losing data.
But I have a quick note for you, if you have a micro sd card will make everything better.
But if you don't, just upgrade using latest Odin version v3.12 by flashing THE BL, AP, CP......AND MOST IMPORTANT THE CSC FILE....Don't flash the HOME_CSC. You won't lose anything at all my friend.

Can anyone who's flashed this confirm if the modem works with band 12, or if we still need to use the TMO apk3 modem?

As a matter of fact, T-Mobile's SM-G935T also released an APL4 Firmware update.
So we are better off flashing the latest CP File from SM-G935T into the G935U APL4 Firmware.

Hello there pal,
I've sucessfully flashed this update and the VERY FIRST THING I NOTICED is a SMOOTHER UI. During the setup I noticed an increase in speed and touch response.
Samsung Pay comes in by default and it can't be disabled by default. Other than that, the ONLY down I noticed....AND I MIGHT BE WRONG GUYS BUT....I am actually surprised to notice significant battery drain
Have you personally went on to flash this update??

Perhaps quarkw something was not or was checked that caused the pit to partition your puppy with Odin. When you flash via Odin from one one rom to another there is always a chance of losing data.
Once you wipe cache in the recovery step (if you did this step) there were some other options that may have wipe the phone or your MicroSD card.
The files may actually be present and you may have lost root, if you had it. There are so many variables that could have happened.
It sucks to loose data, it does.
But look at it as a learning experience and make the time to perform the following steps next time.
If I were you, get root then get TI backup over at google play (get the paid version) to backup everything to your MicroSD that way you can always flash without losing data.
TIP: save your present contacts with their phone numbers, email address & address to Google Contacts, so whenever you flash and format, your contacts will be there automatically with you once you sign into your Google Account.
Perhaps I may write a tutorial on how to flash / backup rom & data APKs and such. It took me a while to learn the ropes too.
I'm pretty sure you flash the HOME CSC file if you DON'T want to lose all your data, thats what I've read else where here on xda

Yes if you were using the G935T CP modem you do have to flash the API3 modem in the CP section of Odin to get the OTA update for APL4. I didn't lose any data doing this.
Also I could have sworn I could still use Wifi Calling on the API3 firmware. But I definitely can't on APL4. Can anyone confirm if you do have wifi calling with the API3 firmware with the US unlocked modem or API3 firmware with the T-Mobile APK1 CP modem?

Hi guys,
just bought a new Samsung Galaxy S7 (SM-G930F).
Of course I got it with the Android 6.0.1 but I want to upgrade it to 7.
As for now, my build has no OTA updates to 7, but I saw that there's a UK build for Android 7.
Question is... if my build number is G930FXXU1BPLB, can I upgrade it to other build number, as for example to: G930FXXU1DPLT ?
And.. if I can do that... Will I get OTA updates of the future releases? It's important to note that I live in Israel, so what happens if I Install an UK build?
Will it block me to get OTA updates because I'm not from the region?
Thanks!
Everything works, except WifiCalling and VoLTE, if you switch to a british firmware.
So OTA's and the like won't be a problem. It's the same experience as if you were using your current german firmware in Israel.
For OTA's be sure to use the correct CSC file, so it get's changed aswell. DBT/BTU mix stuff won't get you OTA's
Given that i had a problem with restoring WhatsApp's chatlog when switching from 6.0 to 7.0 (which according to google and a post here, i'm the only one to have it), it's still advised to read up on app compatibility.
Also it's advised to do a factory reset after flashing, so everything is reset.

So I understand you won't any problems. And I don't really need the WiFi calling.
But about the VoLTE, do you mean that I'll loose the 4G ? Or do you something else?
About the CSC, I have to admit that I don't really know what it is. Is it a file that comes with the files that I should flash?
About the build number, I've just saw that there's a newer build of UK according to sammobile website: G930FXXU1DQB3 (released on the 06/02/2017), and the G930FXXU1DPLT (released on 16/01/2017) that I've stated in the original topic.
Is there a difference between them, should I go with the G930FXXU1DQB3 ?
Thanks again.

VoLTE is the "new" standard for calling.
Normally, when you call someone and don't use VoLTE, you fall back to the local 2G/3G network, which is slower and has lesser quality. Since many providers, atleast in my country, haven't completely switched over (for example prepaid customers still have the outdated 2G/3G calling), you should not notice much of a difference, since it's the same call quality as in 2013 for example. You will still understand people, as they will understand you.
4G / LTE data connectivity is unaffected by it and works without any problems, regardless of country etc. , unless you travel to america and use a local providers sim card there, where you might need the Snapdragon variant of the S7.
That being said, i flashed the newest firmware (DQB3) and it works flawlessly, except afromentioned WhatsApp problem. The only difference is, the update dated to the end of january is included, which fixes some stuff.
A CSC file contains country specific settings, like frequencies used, APN's and even carrier brandings are found in this file, which is why they might differ in size for different regions/carriers.
Because of that, VoLTE and wifi calling might not work, since, in this case, they use the BTU networks standard and you are not in the UK but Israel, aswell as probably not using a british provider.
Anyways back to your question:
There are 2 CSC files, the ROM`s CSC one and a HOME_CSC.
To receive OTA's, you will need to flash the normal CSC and not the HOME one. This will reset and wipe your device (backup all important stuff beforehand) and you get a device "fresh out of the box" bought in the UK.
The HOME CSC does not wipe your memory, but you won't receive OTA updates aswell, since your device hasn't changed it CSC and thus "is not an original BTU device".
So if you go down that route, which is perfectly acceptable and should not make any problems, you will have to flash updates manually via Odin.

Currently doing a downgrade with full wipe to 6.0.1 and then update via OTA. Let's see if that fixes it. Otherwise i have to start clean

Guys, what about Samsung Pay and Android Pay? Are they working fine? I am on XSA. Australia has Samsung pay and Android Pay working.

Just a question can some confirm if using stock Samsung browser when keyboard comes up but prodictive text don't work. But when using chrome it works?
I've got a question too. I would like to change my 6.0.1 on 7.0, also British stuff but I'm a little bit concerned about mixing XEO and BTU. Is it possible to mix 6.0.1 HOME_CSC XEO (latest) with 7.0 British BTU + PIT file from the 7.0 BTU Home (I would like to make factory reset and have my native CSC file)? Does it make difference to take PIT file from 6.0.1 or 7.0 Home file either?

For Samsung Pay, i can't confirm, but since Android Pay definitely works, Samsung Pay should work aswell, if you did not trigger Knox etc.

You can mix it, but personally, i advice against it. Might reduce battery life, you will have to flash every update manually, since OTA does not work with a mix of XEO/BTU.
Also, since XEO and BTU share a common CSC file (they are OXA's, multipurpose CSC's) in most nougat roms around, you might need to root anyway to completely switch over, if a repartition + factory / cache reset won't work.
So to summarize, yes it's possible to use the HOME_CSC to avoid switching your CSC and wiping your phone. It's also possible to stay on a 6.0.1 CSC, but! there might be problems later.
If possible always do a fresh install and if your phone runs well currently, why not stay on Marshmallow? Depending on the current OTA release, which you might have to look up for your country, it might be better to wait a bit. Personally for me, it'd be a complete switch over, since i am too lazy to flash every update manually.
That being said, you won't need a PIT file going from 6.0.1 to 7.0, since it is included in the CSC. Pit files might be useful, if you want to downgrade and in some other cases, but not if you just want to upgrade. They include repartition infos, which are important, if you don't have a "4 file flash" (yucks, my english for explaining it better, sorry).

Yeah, but that wouldn't be a problem for me, cuz I've been using custom ROMs manual flashing on my old fellow Galaxy S4, whenever update was avaiable but anyway, who doesn't want to make things easier?

Sorry for the late reply, work called.
Usually a BTU won't draw more battery or anything, since frequencies mostly are standard in every country. It's more like saved APN's etc. (which you can change manually via your phone's settings menu anyways). But as previously mentioned to the original poster, you can depending on where you live, loose out on VoLTE and Wifi-Calling, since those a carrier specific and usually not included in an unbranded ROM. If those are important to you, you probably want to stick with your current ROM, even if i do understand that new things are always fun. Even i did not wait for my carrier..
But having OTA updates and stuff like that is convenient, otherwise you'd have to flash every update like this one, which is why i recommend using a full BTU firmware, if you really wanna do it. Well, you don't have to flash it manually.. but it won't change since OTA updates are CSC based. So for example if Android 7.1 or another security patch will come out, you will need to wait until your XEO (Poland, i presume?) firmware get's the corresponding update, which according to you might take ages, since the original Nougat is not even out yet.
If you only have an AP file, i recommend using updato.com / samfirmware to download the current image of the BTU. Since you will need Bootloader and Modem files aswell (BL, CP respectively), aswell as the CSC file. I have checked though, your current CSC is included in the OXA (multipurpose CSC) of the BTU. So you might wanna flash a non BTU image first to change the CSC to something not included in the BTU one. Otherwise you will need root access to change it manually and this triggers Knox as we all know and thus your warranty is gone. And if you flash a non BTU image, be sure to factory reset / clear cache via recovery mode after installing and then let it boot normally, so the CSC change will take effect, afterwards flash the BTU image will all files and do the same. Be sure to backup your data beforehand, since they will get lost and do NOT use the HOME_CSC file. This one is for not changing the CSC at all and will retain your data. Use the ROM's CSC. Also always check the rom for your model, i have seen people who used a 935F (which is the edge) ROM on a flat S7 (which is 930F in europe mostly). But that's why i highlight it.
If you have further questions, i'll answer them to the best of my abilities
Oh and i almost forgot, you don't need a pit file . It's really just for more engineerical purposes as explained in ODIN. Current Marshmallow and Nougat Roms consist of 4 parts, which include the corresponding PIT.
I highly recommend not using the PIT file, if you don't know what it entails (you will need to look on the internet for it, since it will be quite lengthy if i explain). In short, as long as an update does not use a different partition layout and / or you mess up your partitions by yourself, you just don't need it. And doing afromentioned, would require extensive knowledge about Android anyways. As long as you don't root and modify your system yourself, you most likely will always be fine. And since rooting does have it's drawback (like some Apps not working due to security, Samsung warranty void etc), i'd not recommend it anyways, unless you are experienced

XEO (Poland, i presume?)

Yes, exactly.
If you only have an AP file, i recommend using updato.com / samfirmware to download the current image of the BTU.

No, I have 4 file package from Sammobile, but the previous question was about what could I do when I have only AP file. But I know this now
Since you will need Bootloader and Modem files aswell (BL, CP respectively), aswell as the CSC file. I have checked though, your current CSC is included in the OXA (multipurpose CSC) of the BTU. So you might wanna flash a non BTU image first to change the CSC to something not included in the BTU one.

For Example?? And If I want to make full switch over towards BTU, should I really need to flash something non - BTU or just pure BTU (with BTU CSC file)? And what if my carrier will release XEO 7.0 stuff... then would I need to flash the same non BTU/XEO stuff to change CSC again?
Oh and i almost forgot, you don't need a pit file . It's really just for more engineerical purposes as explained in ODIN.

I have used the PIT file when I was debranding, that is why I was asking about extended purposes Obviously, I haven't got extensive knowledge about android but I know just the basics (the reason why it looks like that is I am not programming anything, otherwise I would know more, much more).
And, using occasion... Since S7 ownership I was wondering how root would affect function "safe start". Would it be possible to bypass this function COMPLETELY after launch, on the rooted phone (For example: if someone could steal it and unluckily, had extensive android knowledge could bypass launch/start password, and, the worst, security lock, when my phone is fully rooted)?
I purchased an "unlocked" S10e off Swappa. It works on my Mint Mobile account just fine. But, it has the ATT carrier branding and bloatware. And, it's stuck at Android 10/October 2020 Security Update/OneUI 2.5.
Can I Odin flash the U1 firmware without causing any problems? It's my understanding that the G970U1 is essentially the same device, but sold by Samsung as SIM unlocked and with no carrier branding/bloatware.
If I download the U1, would I / should I push BL, AP, CP, CSC *and* USERDATA?
Thanks.

I ended up using the Samsung Firmware downloader from here
Samsung Firmware Downloader is a free cross-platform tool to download software updates for Galaxy devices
Looking to download software updates for your Samsung Galaxy device? Check out Samsung Firmware Downloader - it's free and open source!
www.xda-developers.com
Pulled down the latest G970U1 with region XAA. It handled the decryption.
But reading folks having issues going from a U to U1, vice versa, or separate carriers, I found this and downloaded the latest version (originally found linked from here https://forum.xda-developers.com/t/...-cant-flash-u1-with-odin-etc-att-s21.4238775/)
Patched Odin 3.13.1
For those looking for a modified, modded, or patched odin that is a newer build than all the fake and renamed prince comsy 3.12.3 versions floating around. I patch recent Odin versions to offer similar functionality to the princecomsy; in that...
forum.xda-developers.com
I then extracted the five files and pulled them into the patcheD Odin. Powered off the phone. Started download mode (down vol+bixby button) and plugged in. Odin saw the phone, I clicked start and it finished in only a few minutes.
Is U1s bootloader locked like the u Version?
What about the Canada W?

Can we get an update? How did it turn out? Were you able to get OTA updates? Everything work okay?
I might try this at the library tomorrow. Downloading firmware really sucks without wifi.

I don't believe this process provides an unlocked bootloader.

A little scary process, but overall I'm happy and have had great success. I've received two monthly Security updates since flashing. All the branding/bloat is gone (well, still have Samsung bloat, but that is easily dealt with).

I have bought myself an s10e 256 GB from the US and i am stuck on Android 10 June 2020. ATT wont give me any Updates because i am i Germany and do not have an ATT sim card.
The phone is unlocked as my german sim works fine.
I have ATT bloatware on there ....
The phone tells me i am on TE8
SmartSwitch tells me it has the latest FW
So can someone point me to a newbie description how to to Flash Android 11 onto it.
Never done this before. Never rooted but jailbroken all my iPhones. Android is comlicated in this regard.

hey, im using g970u from verizon, and im using it indonesia far from usa and it work with my carrier. But i want to change the firmware with the g970u1 for fast update and latest security patch. i Downloded the VZW g970u1 and trying to flashing with odin 3.14.4, 3.14.1, 3.13.1 (including Patched version) but nothing is work, it stuck at setup connection and ended up with fail. How i solve this? many thanks
Excellent share! I purchased an s10e snapdragon unlocked version SM-G970U.
The service provider/Carrier version was ATT/XAA/ATT.
It had all the AT&T bloatware, but my simcard worked fine in the phone (I am based in India)
Furthermore, it had Android 11 and I was not able to upgrade to 12 as it kept saying "phone is up to date" whenever I searched for new updates.
It also dint have that mobile data toggle switch in the drop down task bar.
I followed all the steps in the second post of this thread and I was able to upgrade it to Android 12!
Now the service provider/Carrier version shows as = XAA/XAA/ATT (SM-G970U1). All the ATT bloatware is gone and the mobile data toggle switch is now visible in the drop down task bar. My simcard works fine too!
Good stuff. Thank you @dwcasey .
