Hi All, I want to continue using my AT&T prepaid plan but I recently bought a locked T-Mobile Galaxy S7 SM-G930T (I'm going to try to unlock it - if that doesn't work this is all moot). I would like to flash AT&T firmware so I can use the AT&T LTE bands. Can I follow the instructions in the link below once I've unlocked a T-Mobile SM-G930T and turn it into a SM-G930A?
http://www.droidviews.com/nougat-firmware-on-att-galaxy-s7s7-edge-sm-g930a-g935a/
I've read the link below... but it seems to be only if you want to continue using T-Mobile service which I don't.
https://forum.xda-developers.com/tm...w-to-flash-att-nougat-to-t-mobile-s7-t3553610
Changing firmware doesn't have anything to do with what bands the hardware supports. Unlock it and throw the ATT SIM in. Only difference is carrier supported features and software (wifi calling, etc). Flashing ATT modem might improve coverage but all S7 support the same bands.
Thanks buddy for the reply. I'm used to using a custom ROM on my Android phones so this is new. Mostly CyanogenMod.
That's good to know I don't need to flash in order to get the bands but I understand I need to if I want OTA updates from at&t. It seems relatively simple that you just flash the AT&T ROM over the T-Mobile with Odin and then use some update file. It doesn't even effect Samsung pay and Knox which is great.
Stupid question: is the AT&T modem included with the AT&T rom? Also, with regards to the 2nd link in the OP what is the update file that you put on the sdcard to use in recovery - is that an OTA update because your ROM is different from your carrier?

The following is the latest G930A Android 7.0 firmware file. All you need to do is flash it with Odin's AP slot to completely convert your G930T to a G930A. No other steps or files are required: G930AUCS4BQC2_CL10280464_QB12904132_REV02_user_low_ship_MULTI_CERT_meta.tar.rar

I don't get why you would do this other than to have ATT bloat over TMO bloat (IMHO TMO has less bloat than ATT). There's no technical advantage. Am I missing something?

The amount of bloatware is irrelevant since you can freeze all bloatware on either build. I experienced many issues on the TMo version including issues with Android Auto, Google Assistant, and Tasker. I thought these apps were buggy but all of those issues were resolved on the AT&T version. The AT&T version seems to be a better, bug-free build.

Read that in a different thread you posted to after I responded. I think it's very YMMV though. But if you saw improvement then ??
Hi, did anyone ever complete this flash from SM-G930T to SM-G930A? I'd like to do this solely to try and get the wifi calling feature since my workplace has poor cell service but great wifi. I bought the T-Mobile phone, unlocked it, put the ATT sim in and everything but wifi calling works fine. I appreciate the reply!
This is much later in the year (11-8-2021) and ATT has posted the list of phone they say will work and it only shows G930A. It seems their test of working means it must have been sold by ATT. They say My G930T won't work. So Will ATT continue to use customer's unlocked phones it they were not orginally sold by ATT. They have the records. Will ATT refuse to use one of their SIMs even if the phone is Flashed to ATT logo. I do not want to throw away my G930T phone.

Hello and thank you. You posted this information and link back in 2017 and so much has changed. Mostly ATT is now working hard to get rid of all 3G towers and firing up 5G. They said my Galaxy S7-GM930T would not work so I think they link you posted will help me convert the phone back to a GM930A or U or U1. My question is,..Has anything in your post changed since 2017 and if so could you please advise me of what I need to do. Thanks very much.

Hello Everyone,
This is a Guide to Flashing Carrier Specific official ROM's for SAMSUNG GALAXY S7/ S7 EDGE [SM-G930U] [SM_G935U]
Since 5 months as a owner of this device, i was furious to samsung as they have forgoten about this model and never released a security update and still haven't released update for Nougat.
As, all the carrier specific models have been already updated to nougat and stable. I suggest to everyone who is having these models to Flash their carrier specific firmware.
1) First, when deciding which carrier ROM to flash, you need to know who is your provider. You might be using the Big four carriers like AT&T, T Mobile, Verizon, Sprint, which is a pretty straight forward answer.
But, like me there must be several other who like to use prepaid carriers to get best value for money. I use H20 and the network provider is AT&T, which means i must flash AT&T ROM.
In order to find out, which network provider your carrier uses, go to this below link and find the name of your carrier.
https://en.wikipedia.org/wiki/List_of_United_States_mobile_virtual_network_operators
2) After defining which carrier firmware you need, download them from below links.
S7:
AT&T Firmware - G930AUCS4BQC2 - http://gsm-firmware.com/index.php?a=browse&b=category&id=7977

and any us cellular carriers
S7 - G930R4TYU4BQC5 - sorry, i could not find the link for official firmware which are faster, you can download from sammobile which is very slow - https://www.sammobile.com/firmwares/galaxy-s7/SM-G930R4/USC/download/G930R4TYU4BQC5/128660/
S7 EDGE- G935R4TYU4BQC5 - http://gsm-firmware.com/index.php?a=browse&b=category&id=8492
3) In the above links, download four files named AP,BL,CP,CSC.
Now, cut these four files and copy them into a separate folder.
Next, download a file extractor, i suggest you to download 7 zip HERE http://www.7-zip.org/
Install it and then extract each file into the same folder.here you must be having four .tar.md5 files.
4) Now install odin, just download this specific version which works, only with the unlocked model. https://www.4shared.com/s/fBjP73CGjei
The method on how to use odin to flash, you must learn here, if yoou dont know how! http://www.droidviews.com/install-stock-firmware-on-samsung-galaxy-devices-using-odin/
If you knew proceed. Rember: Download the Odin from the above link, its a must or else if you use any other version, it won't flash and your device will be factory reset.
Voila, Now you will be having Nougat on your carrier rom.

But still no U Nougat right?
Yes, Still no nougat. I think this has been an operation by carriers not to release any update untill all of them have updated, so that people who bought these models won't buy again and only buy from them next time.
G935uueu4bqd2
7.0
Seems to me that the 4share does anything but actually download ODIN and I always get a mismatch/fail.
I find a legitimate ODIN download site and it fails. DO NOT FOLLOW THESE INSTRUCTIONS.
For those who aren't already aware, G996U is the model number of all of the US carrier versions of the S21+. The G996U1 is the model number of the same device, but sold by Samsung SIM unlocked and with no carrier bloatware. Firmware is 100% interchangeable among these models: any U or U1 firmware version can be flashed to any U or U1 device at any time, assuming that you're not trying to downgrade the bootloader. A "U to U" or "U1 to U1" flash does not require a factory reset, but changing from one firmware to the other will require one. Also, U firmware is identical for the 4 base files (AP, BL, CP, CSC) for each individual build, no matter which carrier it comes from. So if you download 2 different carrier versions of the exact same build, the 4 base files will be identical. Where the firmware differs is in the USERDATA file - that's where the carrier bloatware and customizations reside.
Manual Odin flashing is designed for those who:
- want to manually update to a newer version of U firmware on their U device, either because they don't want to wait for their carrier's OTA or because OTAs aren't working on their device, or a different carrier got a new feature/patch before they did
- want to flash U1 firmware to their U device
- want to convert from U1 firmware to carrier U firmware
- want to convert from one carrier's U firmware (with all apps and bloatware) to a different carrier's U firmware (with all apps and bloatware)
For those who aren't already aware, anyone can now download firmware for almost any Samsung device any time that they want, via the various firmware download tools posted here on XDA like SamFirm or Frija. There are threads and info about them here on XDA so I won't waste time explaining - do a search if you're not already familiar with these tools. But they only provide whatever the latest/newest/current version is - nothing older. I pay for a subscription to a site that gets the official releases (usually) before they hit the firmware download tools, so that's where my files come from.
This is not a "beginner's guide to Odin flashing" -type post/thread, so I won't list basic, step-by-step flashing instructions. My threads are geared towards those who already know what they're doing. If you're new to manually flashing Samsung firmware (or haven't done it in a long time), I recommend you consult one of those "beginner's" guides- there are tons of them here on XDA.
Happy flashing!
U firmware: https://www.androidfilehost.com/?w=files&flid=322091
U1 firmware: https://www.androidfilehost.com/?w=files&flid=322092
Notes:
- DON'T QUOTE THE OP WHEN YOU REPLY, kthx
- I have lots of threads just like this one for other Samsung flagships, if it interests you. For those who have already made use of my previous threads for a different device and are upgrading to an S21, welcome back
- My zips are compressed extra small for space and bandwidth savings. The default Windows extractor can't handle it, so you'll need a 3rd party tool like 7zip, WinRAR, etc
- it's quite time consuming to download the files, zip them up, and upload them to AFH. And, I do threads like this for every single Sx and Note x model, so I won't be uploading every single version. The only full builds that I upload are ones where I get access to a new bootloader and/or Android version early, before they hit the firmware download tools.
- My naming method for folders on AFH is: build - bootloader - Android version
So "SAT - 1 - 9.0" means the full build number ends in SAT, it's bootloader version 1, and it's Android 9.0. When bootloader and Android versions increment, the first build to have those changes will have its folder notated appropriately.
- HOME CSC file keeps data intact; using the other CSC will wipe data. Flashing USERDATA will also wipe data.
- Since AT&T doesn't allow their firmware to be publicly available (for any of their devices), I'll try to always upload at least one USERDATA per bootloader increment for AT&T (and Cricket, if they get this model). I'll also upload any full builds if AT&T is the only carrier to get that specific build, because you won't be able to find the files anywhere else.
- For identifying USERDATAS, and to know what region/CSC to use in the firmware download tools if you're downloading yourself:
AIO = Cricket (not available via firmware download tools)
ATT = AT&T (not available via firmware download tools)
BST = Boost Mobile
CCT = Xfinity Mobile (Comcast)
CHA = Spectrum Mobile (Charter)
DSH = Dish Network
SPR = Sprint
TMB = T-Mobile
TMK = Metro PCS
USC = US Cellular
VZW = Verizon (available via firmware download tools, but Manual Entry is required - Auto will not work)
XAA = U1 firmware
- the correct procedure for switching from one carrier's firmware to another is:
1. Flash full U1 firmware package including non HOME CSC
2. Upon boot, insert a SIM of the carrier whose firmware you want
3. Watch for the popup that says "reboot to apply new carrier settings" etc, and do it
4. After that restart completes, reboot back to Download mode and flash the full U firmware package, with the USERDATA file of the carrier whose firmware you want
Initial U firmware and AT&T USERDATA are posted, along with U1 firmware. U firmware is not yet accessible in the firmware download tools like SamFirm and Frija, but if anyone wants a different carrier's USERDATA (for flashing bloatware to a U1 device or for converting a U device from one carrier's bloatware to a different one), let me know and I'll get it for you

This thread is in the S21+ forum, not the S21 forum.
This thread is for model numbers G996U and G996U1, not G991U or G991U1.
If you're looking for S21 firmware, that will be found in the S21 forum
I agree with you
Does the firmware control the SIM lock? So, can you flash the U1-XAA firmware and use say a phone purchased from AT&T on another carrier? Or do you need to do the SIM unlock before flashing?

SIM unlock always goes much deeper than firmware. Flashing U1 will never automatically unlock any model - the unlock has to be done separately. If desired, I can provide a recommendation for a professional 3rd party business to do the unlocking, for any interested users who may not meet the carrier's unlock requirement(s).
Thanks. That's what I figured, but wanted to make sure. I like to get off of the AT&T firmware as quickly as possible as you can't get their updates unless you have an active SIM in the phone.

3.14.1 patched
I don't have my S21+ yet but it will be here soon. I ordered from Samsung and selected the Verizon version as unlocked was considerably more expensive.
Does anyone know what Verizon specific bloatware the S21+ has?
Are there certain apps which can be uninstalled with the U1 version but not the Verizon U version?
Are there any potential speed benefits on the 5G network that would be lost using the U1 version, or features like tethering that won't work?
For updates in the future, would they arrive faster on the U1 version, slower, or the same?
My main purpose in flashing from U to U1 is to free up the maximum amount of space of the 128 GB while still retaining 100% of the speed and features I would have with the Verizon version.
Thank you for educating me! It's been a couple years since I flashed my Note 8.
I order a unlocked S21+ U1 version straight from Samsung and didn't have to put in any VZW info.
There is a buttload of Samsung bloatware but no VZW except fot MyVZX

Dialer codes usually don't work on VZW firmware, whether U or U1. But they almost always work on TMB and all others.
Have you tried *#06# ?
I'm not too familiar with this community or android rooting in general but I still want to see what I can do. I want to know more than just the state of rooting, is there a way to unlock the boot loader, is there a way I can remove some (if not all) of the preinstalled spyware and replace it, what can I do to better protect my privacy? I figured I'd check out this community as this is where I was lead when I wanted to root my old Kindle Fire and since this community doesn't just direct to sketchy proprietary tools like kingroot (or maybe you all do, IDK I haven't been here very long). If I could remove alot of the spyware/bloatware I wouldn't be as concerned with rooting or flashing a custom rom as those would be just nice to have if I could get the preinstalled OS to be more privacy focused. I know I can't really escape google since they're embedded right into android but what can I do about Samsung? If I can't do anything on the device I would still like to know if there is a list of domains I could block using a pi-hole. Thanks if anyone has any info, also my phone is from the T-Mobile distribution, I feel like that probably matters.

The reason I specified replace is that I already tried this and it broke nearly everything, for example:
despite the fact I have a different keyboard, all keyboards broke, I couldn't get the keyboard to show up.
The entire OS became very unstable

Without TWRP, replacing the OS will be impossible.
Maybe downgrade to a older phone that has greater custom ROM support.

Not fully bricked, but it can be semibricked, i.e. not completely working as a mobile phone.
Xiaomi boot loops when certain apps are disabled, which is nasty and needs a factory reset to 'unbrick' it. Not sure about Samsung.

I think you removed things that shouldn't have been, or you didn't have the alternate app (e.g. keyboard) set as default. If you look at my post history, you can find the debloat list that I posted, which is 100% safe to remove without affecting the usage in any way whatsoever.
More aggressive debloating is possible, sure, but you risk breaking some things. You can always reinstall whatever you removed with "pm install-existing" as long as you used -k when you removed.

Wait, de bloating can get the device bricked?
I was able to fix it by just reinstalling everything from pm

No , unless your rooted. whatever you debloat while unrooted can be fixed doing Factory Reset

I'm not too familiar with this community or android rooting in general but I still want to see what I can do. I want to know more than just the state of rooting, is there a way to unlock the boot loader, is there a way I can remove some (if not all) of the preinstalled spyware and replace it, what can I do to better protect my privacy? I figured I'd check out this community as this is where I was lead when I wanted to root my old Kindle Fire and since this community doesn't just direct to sketchy proprietary tools like kingroot (or maybe you all do, IDK I haven't been here very long). If I could remove alot of the spyware/bloatware I wouldn't be as concerned with rooting or flashing a custom rom as those would be just nice to have if I could get the preinstalled OS to be more privacy focused. I know I can't really escape google since they're embedded right into android but what can I do about Samsung? If I can't do anything on the device I would still like to know if there is a list of domains I could block using a pi-hole. Thanks if anyone has any info, also my phone is from the T-Mobile distribution, I feel like that probably matters.

It can be rooted with Magisk V23.0 but you need to unlock the bootloader first.
The bootloader is unlockable up to V3 but this is a paid service.
To get rid of this bloatware i would suggest you flash an unlocked firmware.
You can always flash a SM-A326U1 XXA ROM (https://www.sammobile.com/samsung/g...M-A326U1/XAA/download/A326U1UEU3AUF2/1558540/) by using a patched version of ODIN 3.13.1 or later. I was able to do this using ODIN 3.1.4 3B
I now have a TMO SM-A326U without any preinstalled TMO bloat. The XAA rom did not install any TMO software that I noticed at a high level and seems like a plan stock A32 5G.
Just make sure the SM-A326U1 baseband is the same version or high than the installed SM-A326U. The base band number will be the 5th to last number in on the About page under baseband.
Edit * I was checking my computer and noticed I had the SM-A326U1 roms for XAA and TMK. I can’t recall if XAA gave me an issue during the flash and I needed to use TMK, but the end result is, my A32 5G has no TMO bloatware installed.
I hope this helps someone.

The XAA and TMB are what are referrred to as CSC codes. Each carrier has their own:
ACG – Nextech/C Spire
ATT – AT&T
CCT – Comcast
LRA – Bluegrass Cellular
SPR – Sprint (CDMA)
TFN – Tracfone
TMB – T-Mobile
USC – US Cellular
VMU – Virgin Mobile USA
VZW – Verizon
XAA – USA (unbranded/unlocked/default)
XAS – USA (unbranded/unlocked)
ODIN is software used to flash firmware on to Samsung devices while in Download mode. I believe you need to use a patched version of ODIN to cross flash devices. Regular ODIN will most likely error out during the flashing process.
The SM-A326U is a carrier branded device which is why you will probably not find a ROM with a CSC code of XAA for these devies.
The SM-A326U1 I believe is the carrier unlocked version of the device. Regardless of the CSC you flash, don’t expect to get SM-A326U TMB flashed with the SM-A326U1 XAA firmware to enable OEM Unlock in the Developer Settings. It hasn’t appeared for me and I wouldn’t expect it to.
Please feel free to correct any of my assumptions above. I’m an iPhone guy using this phone with my ASUS router as a failover if my ISP goes down. Just tinkering with it from time to time.

OEM unlock wont appear on the A326U.
The SM-A326U1 XAA & SM-A326U1 USC should be the debranded versions.
The XAA FW causes CSC to revert Whilst the USC doesnt.
Theres is NO XAS FW for this device.

So from my understanding:
There is a tool known as ODIN, this can be used to flash new roms
and from what I seem to know
I am most likely running a TMB version of the ROM as it was the default for my phone as it is a TMobile OEM version
So my question is now this:
How can I get a working version of ODIN
Where can I find a safe XAS rom to flash
I don't know if my phone is unlocked, if my phone is still locked to TMobile, could this mess with anything?
I am using SM-A326U not SM-A326U1, I assume the 1 version is unlocked?

ODIN is the software used to flash ROMS on to Samsung devices. You will want to look for ODIN 3.1.4 3B Patched On the forums or a search engine. The patched version of ODIN will allow you to flash ROMS with different CSC codes. It removes this restriction.
You are correct that the CSC code for your device is TMB. The CSC codes I listed above are some examples, not a complete list. There are no XAS CSC ROMs for this device that I am aware of, just as financeledger stated.
Your Samsung A32 5G is actually the SM-A326U model, but the SM-A326U1 roms also work on these phones, provided you use the patched ODIN. Only the SM-A326U1 has a XAA CSC rom which is bloat free. I have not tried the USC variant but I switched between the SM-A326U TMB and SM-326U1 XAA ROMs and back last night without any issues. You can find the ROMS at Sammobile.com SM-326U1 Roms it will be the third one in the list with the carrier name of Unknown https://www.sammobile.com/samsung/g...M-A326U1/XAA/download/A326U1UEU3AUF2/1558540/

Doing this will not unlock the phone in any way, shape, or form. All this does is provides you with an A32 5G without any carrier bloat. The boot loader still cannot be unlocked and the sim will remain locked until you’ve met T-Mobile’s conditions for unlocking.
I’d recommend on reading up on how to use ODIN properly as you can brick your device if it is not used correctly. Feel free to reply back if you still have questions. I’m not knowledgable enough to understand what financeledger meant when they said the CSC gets reset using the XAA vs USC rom. Hopefully they can provide some additional details regarding that.
Ok
to be sure I get it right:
Here is what I shal do:
1: Download https://forum.xda-developers.com/t/patched-odin-3-13-1.3762572/
2: Download the XAA ROM for the SM-A326U
3: Flash the ROM with ODIN
4: Hope I don't brick my phone
Is this right?
Hello, I would like to preface this by saying that I don't actually live in the US. I got this used unlocked AT&T Galaxy S21+ a few months back and an issue I noticed after using it for a while was the fact I was not receiving any OTA updates due to the fact I was not using an AT&T SIM card.
Now I want to switch AT&T to carrier-free firmware where I will be able to get regular OTA updates automatically
My current specs:
Model: SM-G996U
chip: Snapdragon 888
Baseband version : G996USQU1ATLF
CSC : G996UOYN1ATLF
AP/CP : G996USQU1ATLF
Is it suitable for installation?
https://www.sammobile.com/samsung/g.../SM-G996U/USC/download/G996USQU5CVDB/1640229/
N.B/: May doing this flash will brick or damage my phone?
On SamMobile, underneath my device model, there list of several firmware labeled with different US carriers. As long as the firmware I flash is under the model number I have (SM-G996U), nothing should break, right?
Please suggest me firmware. I want to get rid of carrier barrier and want to get regular updates automatically safely.
Did you try the rom? I have the same problem
OTA is CSC based. You'd have to use Samkey to unlock the CSC to a unlocked US one.
Flash the u1 xaa firmware. Works on my phone in canada
I have a similar issue!
So I received a refurbished S21+, it is unlocked and all but it has AT&T bloatware and I can't update to oneui 5.0... I live in italy but this phone comes from Germany and apparently has a US AT&T firmware (SM-G996U-OYN-ATT). I was following a tutorial with odin to flash to SM-G996B with ITV, which is the italian version with android 12 and oneui 4.1.1 is it safe to do so and then get the android 13 update the standard way? Could I straight up get android 13 and oneui 5 flashing the most recent rom or is it even worse?
The other solution I thought about is that I could just get the U1 XAA, but i have U for now and I don't quite understand if it's completely risk free or not.

I'm having the same issue with my Samsung S20 Ultra 5G SM-G988U i bought the device yesterday and it accept my local Sim here but the issue is that there is limited features, for example I can't turn On/off my mobile data on and I can't change network mode like selecting from 4G to 5G
