I have an AT&T variant of the S10 (SM-G973) and I wanted to flash the stock One UI ROM that is found on the unlocked S10 (SM-G970). Does anyone know if the firmware for the 970 can be flashed successfully on a 973 phone?

Why would you want to flash G970 firmware onto G973 phone? Can't you just flash G973 firmware onto your G973 phone?
My understanding is that the G973 firmware has the AT&T Bloatware and some functions/tiles hidden (like the mobile data tile for quick settings). I'm hoping I can do the stock firmware from G970 to not deal with the bloatware and have more access.

Have you thought about using unlocked G973 firmware? G970 is S10e model
Thank you, Charkatar. I bet if I paid more attention in my search I would have noticed the difference. Next step, find and flash the unlocked firmware!

Use SamFirm tool to download firmware you need ( I have attached zip file) and check out example image on how to search and download firmware your phone needs.
So under model, you would put SM-G973U1 (which should be unlocked model) and region you would put XAA (unlocked model) and click "check update" IF YOUR MODEL IS DIFFERENT FROM MY EXAMPLE, THEN ENTER THE CORRECT MODEL AND REGION YOU NEED

I'm on a Mac and can't open the windows .exe files. I did find a slight work around with Samsung SmartSwitch. Work has been so busy I haven't had time to find and download the U1 firmware for the S10. I"ll let you know how it goes!
Hi
When I downloaded the U1 unlocked firmware, I couldn't extract it. It said the .zip was damaged. Can anyone help or point me in the right place to download the firmware? I tried googling, but it doesn't lead anywhere! Thanks!

Use this SamFirm tool to download firmware for your phone.
Fill out Model and Region sections and you can tick Auto(if not selected)
Example: In the model you would put something like: SM-G970U(S10e phone) and Region: TMB(T-Mobile) - your model and region is probably different. If you need an unlocked US region, use XAA
I've seen a couple of threads about this here, but I'm confused about where I can get the firmware to flash an unlocked S10 (SM-G973U1) to T-Mobile firmware, and they've not really told me where to download the firmware that I need. One thread pointed at S10+ firmware, not useful to me, and the other didn't give any URL for downloading firmware.
Can anyone help me find the right firmware? I've used Odin before, and am fine with that. I also know that I have to have the right firmware for this to work *smile*.
Also, the firmware to flash back from T-Mobile to unlocked would be very useful, since I may want to change back to unlocked at some point. The reason that I want to flash T-Mobile firmware is since I'm still on the May 1 "monthly" Android security update on my unlocked S10. That doesn't make me happy, more than a quarter behind by this point...very disappointed.
Thanks!
There's a firmware thread here:

If the phone is SIM unlocked, the Firmware you want is the USC or XAA firmware... That way it will switch carriers apps and bloatware when you change sim cards...
Search for samfirm on google....
Have Fun!!
For those who aren't already aware, G991U is the model number of all of the US carrier versions of the S21. The G991U1 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=322084
U1 firmware: https://www.androidfilehost.com/?w=files&flid=322085
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)
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
Thanks for the firmware links!
Odin blocks flashing from U to U1 or U1 to U. To successfully flash: Use the patched/modded odin found here.
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...

Anyone from T-Mobile move to u1? If so better or worse. Not sure if I should make the move. Thanks
Is the Verizon userdata available? I have an ATT version and I want to switch to Verizon.
Thanks.

Hey guys, I'm curious if anybody could help me fix an issue I'm having with flashing. I'm trying to flash from the U variant to the U1 but it seems to be csc locked to TMB. I've tried multiple firmwares, pulling the sim out before flashing and even flashing back and forth from U to U1 I can't seem to get the carrier update pop-up at all. I'm kinda at a loss and would appreciate any help you guys could give me

Are you saying the service provider codes stay as TMB/TMB/TMB, even after you flash U1?
Yes the csc is locked to TMB for some reason. I did the full csc non home flash several times with no luck

S21 Ultra users are reporting the same thing. Not sure what's going on with T-Mo this time
Yes I saw the thread. Do you think a repartition could possibly work? It's much more in depth but it would be a completely clean install

I don't, I read that you need a pit code. How would you go about getting that?

If you mean a PIT file, that's already included in the CSC file. So that is flashed, if you flash that file
So it's relatively the same concept but you use the csc file in the pit section?

Huh? No. The only thing that can go in the pit section is the pit file
Oh I misunderstood, you're saying when you flash the csc it automatically flashes that pit file?

Update: I'm completely lost. I downloaded the Canadian firmware which gave me the xac csc then I flashed back to U1 which also updated to Xaa. But I still showed only t-mobile n41 and 71 bands so I flashed back to U with Verizon bloatware and now I have a Verizon U firmware with xaa csc and still only showing t-mobile bands

I don't guarantee that any particular bands will work on any particular firmware. Also, carriers don't use every single band in every single area
So I'm trying to flash Verizon SM-G998U1 firmware on my Verizon SM-G998U S21 Ultra. Wanted to find out if I'll need the Patched Odin Vs. the Normal Odin. I hear the Patched Odin is the way to go for someone trying to flash firmware when moving between regions but I wanted to find out if my scenario is better dealt with the Patched Odin or the normal one. Just looking for a little guidance. Already have the latest Verizon SM-G998U1 firmware downloaded. And now I'm looking into getting the correct Odin to use when flashing my phone.
only use the patched version
