How can I update my unlocked AT&T S9 (SM-G960U)?

Hi. I have an AT&T-branded unlocked S9 (SM-G960U) and I have not been receiving software updates. The date of the installed security patch is Nov. 1, 2018, and I'm still on Android 8.0. When I check for updates, it says that my phone is up-to-date. My current carrier is outside the USA. I have also tried updating via Smart Switch but it also says my phone is up-to-date.
Is there any way I could get the Android Pie update?
Thanks for the help!

You can use the U1 firmware (Unbranded) you don't need the carrier one, any for the U will work, and U1

When I check out the U1 firmwares, I see different variants listed (ATT, TMB, etc.). As you said, the U1 firmware is unbranded, so why are there carrier-specific variants?

in short, the U1 is a debloated version of stock without the carrier junk. The different iterations will have different modem files that are intended to work best with the respective markets they are built for, globally speaking. Samsung stopped making a separate version for the GSM carriers in the USA with the S8 which is why all the stock image files are now cross compatible. They technically always were, its just that theyre far more interchangable now due to this physical difference no longer existing

So do you mean that the different carrier versions of U1 firmware don't have carrier apps, but have files that make the phone more compatible with the carrier's network?

It seems as though AT&T can only send updates over their network, which I don't have access to because I'm outside the US. If I change my firmware to U1, would I then receive updates OTA in the future directly from Samsung?

they have very minimal bloatware, they might include carrier apps, but very few. They usually have carrier specific radio firmware to allow the phone to operate best on that specific network, yes.
i would flash one in the very near future myself, but im about to head to Mexico on vacation, so im a tad paranoid to do so. Ill do it when i get back tho. By the end of this month, ill be running a U1 firmware set

Guys if I flash android 10 again, will system see the next security patch for January

Tired waiting for sprint to send android 10 update.
lame carrier locked.

Use the Frija tool and download the Sprint variant of Android 10.
https://www.sammobile.com/samsung/g...SM-N975U1/SPR/download/N975U1UEU2BSLC/309277/
AFAIK you should still receive OTA updates

Thank you very much, however I am on a locked device and it's a miracle you found a sprint variant even though none reporting they got it on sprint. And the csc says unknown.
I am not ungrateful. I am afraid to flash via odin unlocked variant.
I have firmware N975USQU2BSL7 already of locked devices in the USA but the SPRINT USER DATA MD5 file,. and my query was if i install what I have, when january's patch comes will it update if im on december now. I would not yet try unlocked firmware and thank you for All you provided.

It will still work. The SPR in the ROM stands for Sprint. Check the CSC file to confirm before you flash it but I thought it said SPR. Just flash the ROM using the Odin patched version for it to work.
I am using a AT&T Note 10 with the Star Wars ROM and I just received the Android 10 update earlier tonight. You will still receive the OTA updates but they just might be for the unlocked version if you are okay with that.

For it to get the updates you need to use the CSC that came with the ROM you flash if that makes sense.

I have a question for anyone that may know more than me...
I have an unlocked sprint note 10 plus. Ive flashed it with XAA. So im on unlocked firmware on an unlocked sprint note 10. Im settings my csc shows this... tmk/tmk/spr. Im using metro pcs as the carrier. Where will my updates come from? Using sam info app, it shows the firmware as XAA and active csc as tmk. I have a bunch of avalible csc to use but i dont have the dialer codes with metro. I have inserted a att sim and i have the dialer code to change the csc. However when i put the metro pcs sim in, it goes back to tmk/tmk/spr.
Question 1: With tmk/tmk/spr, on XAA firmware, where will updates come from? Metro Pcs, sprint, or samsung?
Question 2: Are the csc codes tmk/tmk/spr correct being as i am on XAA firmware?
Thanks!

Flashing a AT&T SM-G988U1 update to SM-G988U USERDATA question

My AT&T S20 Ultra has been stuck on the G988USQU1ATBN firmware update. I haven't received any of the new OTA updates and was looking into manually flashing the latest update via Odin. If I were to flash the latest unlocked SM-G988U1 G988U1UES1ATFB update, that I downloaded from SamFirm, to my current AT&T SM-G988U, I would need to use the G988U's USERDATA in Odin to retain AT&T's carrier features like Wifi Calling and VOLTE or is it not possible to enable these features even with the USERDATA on a SM-G988U1 unlocked firmware update? I haven't had any luck finding the latest AT&T G988U update's USERDATA, only the ones from the "G988U and G988U1 Firmware Links and Flashing Discussion Here" topic's U firmware link.
Is it safe to use the ATT Feb 20, 2020 G988USQU1ATAW USERDATA from the U firmware link while I'm flashing the unlocked G988U1UES1ATFB update to my current SM-G988U in Odin? Its my first time flashing a firmware update to a Galaxy phone in Odin.

Help updating to latest update
Could you help me please? I'm so lost on how to use this forum. I've got an sm-g986u on at&t, it's not got an update since June. I'm trying to update it via odin. I don't use a sim card in it as it's not my main phone so I can't get ota updates, and smart switch doesn't work either. I would just throw a sim in it but I guess I bought a blacklisted phone :/ anyway, if I use frija it detects a T-Mobile update for it, but it won't download. It goes for a bit and then drops to zero mb/s. I downloaded the update myself and when I enter the files into oidn, it freezes after I select the cp file and says not responding indefinitely. I just want to get this thing to one ui 2.5. I cannot find any guide for how to do this. Thanks for any insight you can provide. I'm going to try to find a way to make this into a post as well.

How To Guide F926U and F926U1 Firmware Links and Flashing Discussion Here

For those who aren't already aware, F926U is the model number of all of the US carrier versions of the Z Fold3. The F926U1 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 have access to an internal Samsung firmware download tool that usually gets new versions before they hit the public 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=327754
U1 firmware: https://www.androidfilehost.com/?w=files&flid=327755
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, 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 flagship 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
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

Question Updating s22 SD (s901u)

Hi all. I am from Singapore and I have gotten a s22 off an online platform here only to discover it is a USA set.
The csc is S901UOYN2AVE4
I am unable to get ota updates and am still stuck with a may 2022 android 12 update while checking updates shows as up to date.
I have some questions after doing a Google search.
1) will I be able to get ota updates? Does this mean I have to somehow change to csc and is this possible?
2) if it is not, do I have to update manually thru Odin patched? Given the above csc, can anyone guide me as to which firmware can I use? I see there are many different ones from different carriers like Verizon or t mobile
Thanks in advance!

were you able to find a solution? I am also facing the same issue

None so far.

Have you guys tried smartswitch?

hello! I have also researched a bit & came to this conclusion. The device was possibly under a carrier (such as ATT or Verizon) from the US. Although it's unlocked and you can use any sim card but you won't receive any updates unless you use the sim card of that particular carrier. You can install the latest firmware using ODIN tool yourself by downloading firmware based on CSC region code. You can youtube to find the specific CSC region of your phone. Please let me know if you find any other solution. & also please let me know what 'service provider software version' is on your device. you can find it at About phone>Software Information

I have managed to flash it with the right software and get it to update ota. To test this I flashed a older android 12 firmware and it manages to update to android 13 ota.
Follow the steps in this thread closely and you will be good. Use the unlocked u1 version firmware.
https://www.reddit.com/r/GalaxyS22/comments/t49c10

Just to confirm one thing, My CSC is S901UOYN2AVE4 and AP/CP/BASEBAND is S901USQU2AVE4. Csc is basically same as you.
But my service provider software version is SAOMC_SM_S901U_OYN_GCF_12_0002
GCF/GCF, GCF/XAA.
Will it alright to flash u1 unlocked firmware to the device? This software version shouldn't be an issue right?
