How can I update firmware?

Hello,
I live in Korea and not an AT&T carrier user. So, I have never received AT&T's OTA.
I tried to connect my Galaxy S7 Active to Samsung Smart Switch, but Samsung Smart Switch says my phone's firmware is the newest version.
My phone's baseband version is G891AUCU1APE7, and build number is MMB29M.G891AUCU1APE7.
Am I unable to update my phone forever?
I want to update my phone's firmware.
I desperately need your help...
Thank you.

ATT only updates there phones OTA... you have to be on the att network to get it to update.

Given that they allow unlocking of the device, that is a ridiculous policy. I can only hope that someone will be able to download the image so that we can use odin.

looking on the S6 Active thread, they find the update downloads on AT&T site, not sure how ?? you can easily find out WHAT update is the newest ..
then either flash via Odin, or 'side' load it ...
but i couldnt find out how they were getting the links from AT&T site to download direct ..

Updating outside USA
in order to update this device outside of USA you should get a At&t SIM card (whit active account), put and seek for updates and will work, I made it a couple of hours and I was able to update.....All this thanks to a friend who lives in Usa and came to visit my country and lend his sim card to do the test ...

Do AT&T have such things as pre-paid sim cards? And could I activate one outside of the USA?

It exists and is called GoPhone, only you would have to do it through some friend or trustworthy person who lives in the USA and can buy it and send it to your country ... is what I will do for the next updates

(Was a scam site, sorry)

now we have these phones rooted, could people in the US with a OTA updates, pull /dump the updates
for us people outside US to flash via Odin ? ...

I'm looking into purchasing this device but have second thoughts due to firmware update availability (not to mention custom ROM support).
Anyway, related to the topic above, I have an AT&T prepaid GO Phone SIM but it is already deactivated/expired. Can I use this old prepaid SIM to update the device firmware outside US?
Side question, what is the difference between SM-G891 and SM-G891A? I see it often when looking for this device.
Thanks.

Hi aalam .. did you face any issues with update using Odin .. I want to update my device but I'm afraid that I might brick it in the process .. this is not the first time that I update a device using Odin but normally it's just one file and I never needed to use the pit file.
appreciate if you can tell me the status of the device after the update ..

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!

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!

Sim unlocked but OTA updates not

Hello everyone.
I just bought what I thought it was an unlocked S20 Ultra over the internet and, nevertheless my sim card form my country works well (Im from México) the OTA updates dont work.
The last security update it has is from March 2020 and I have checked the system update option but it says that my phone is up to date.
I have seen that maybe that the most recent update can be forced using Odin but I dont know what firmware to download for my model so it can be updated regularly via OTA as I only have found firmware options for another USA Carriers that I dont have, and Im scared to brick it for choosing the wrong one.
Curiously enough, the phone model and IMEI correspond to the AT&T USA variation, however, the start up screen doesnt show up any AT&T logo and the phone doesnt have any bloatware from any carrier. So Im not sure if the phone was already flashed with some fw?
The model that it displays is SM-G988U and the S/W is G988USQU1ATBN'
Hope you can help me to have updates on my phone.
Thanks!

Your device is a US Branded Variant, most likely Verizon/ATT. Go to Settings, About Phone, Software Information, Service Provider Software Version. On the bottom row the last three letters will verify which carrier is branded. If it is in fact AT&T you can download the appropriate fw here. Be sure to select the appropriate carrier in the drop down menu but be aware AT&T typically doesn't offer it's firmware to be accessed online.

Thank you. I just checked and the last three letters are indeed ATT. That means that most likely I cant have fw updates or OTA updates as they dont offer their fw online? Searched on the website yu gave me but there is no ATT carrier option

You're most welcome. Verizon is in the drop down menu and since they've merged with AT&T it should be the appropriate FW but it doesn't load after selecting it which reflects AT&T's ongoing efforts to block updates outside of it's proprietary platform. If you're unable to access AT&T's network inside the US the other options are downloading the FW on Samsung's Smartswitch app or acquiring it on ATT/Verizon website. Good luck!

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?
