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 ..

I've read that the Galaxy S9 hardware is identical for all carriers in the USA.
If I bought a factory unlocked Galaxy S9 can I flash it to the carrier I am using (Verizon, Sprint, T-Mobile, AT&T) to enable carrier specific software and features? Can I flash it back to the unlocked firmware?
I already see a thread about flashing the unlocked firmware to carrier models so I am assuming there are no issues there.
Can one carrier model be flashed to another carrier model?
No, bootloaders are different, with the S7 there was an unbranded U firmware that was compatible with most of them, unlocked firmware will be that one for the S9, but no you cannot just flash different device firmwares to the wrong model
I was able to flash the ATT rom onto my Verizon S9. I got a VZ s9 from work but I'm on ATT. For the most part it's worked great, I had done the same thing previously with a Galaxy S7. I say for the most part b/c I am on here tonight to post a question myself about the fact that I'm getting a delay with MMS messages. I imagine it has something to do with the APNs I have setup, but I can't seem to figure it out.

Did you have to flash to the U1 software first?
I do think that is what I ended up doing... tried to go directly first and it kept failing. Got fed up and decided to just try and put the bone stock rom on it, and that went on really easily.... so after using it like that a few days I tried to drop the ATT rom on it and it worked without issue.

Yes, but you need to go to the u1 firmware 1st then to the other carrier firmware. Also make sure you avoid the newer firmwares with the new bootloader, as the unlocked model and certain carrier models don't have the new bootloader.

That'll be why I still thought that then, coming straight from the S7 > S9

I tried downloading vzw firmware G960USQS3ARI6 to my unlocked sprint s9 and still not vzw flashed. want to do this so can have voice over LTE. Any other steps im missing? flash went through but still sprint
As soon as Firmware ver. 3 came out for the G960U1, I was able to flash it to my Sprint G960U and finally have VoLTE, WiFi calling and stable LTE for MetroPCS. Used samkey to unlock it from Sprint. My phone is actually performing much faster without all of Sprint's bloatware hogging my RAM and storage space. I can confirm that OTA updates still work the same...I received September's security patch (current) with no problems. Device is still official status and Knox hasn't been tripped.
A lot of people think you can just flash the carrier firmware of your choice and boom, it works...I had the same thought process....that's not the case. You have to make sure that there is a matching firmware version for the carrier you want to flash to, as well as make sure the G960U1 firmware version (the unlocked version of the S9's software you have to flash first before even carrier flashing) is the same version of what is installed on your phone now. It's easy ya'll......just READ lol.
I'm in love with my phone again thanks to XDA. ?
HAPPY FLASHING!

Hi, I got one unlocked G960U1(G960U1UES3ARI1) and downloaded new fireware(G960U1UES3ARI1-SPR) from sammobile, but after flashed SPR ROM successfully, the info on the phone still shows XAA, anything I missed here? Thanks!

Well first off, you have the unlocked phone. I don't. My G960U is originally from Sprint, so I'm not sure about carrier flashing regarding the G960U1. I thought it was supposed to provision itself after you put the sim in, and the associated carrier apps will download since it's the unlocked model...but I may be wrong...

I know so many people have already answered your question from some saying No to others saying Yes but you need to Install U1 first and Bla Bla Bla.
I want to give you one specific answer: With S9 you can any Carriers firmware you wish or even Unlocked phone's firmware. You will never have any issue. And you don't ever need to flash U1 or something else before changing carrier firmware you can Flash from ATT S9 firmware to VZW S9 firmware without any issue. You can also flash from U to U1 which is from Carrier specific to Unbranded/Unlocked but only hiccup is original Odin will give you SHA-256 error, which is normal because you are flashing U1 firm to U device or vice versa. This error can easily be resolved by used Patched odin that disabled SHA-256 check. And trust me you will never have any issue.
You will never want to do this but I have gone as far as mix-matching U and U1 firmware together as well. Like flashing AP, BL and CP of U device but flashing CSC of U1 device. and it still works.
hey there, a little late to the party, having trouble with going from a Verizon to a Sprint, even by way of U1. I can't get any of them to work. And I've been told I have to go from VZW to U1 before I went to Sprint. Is that not the case? I'm having a hell of a time getting anything to flash, everything fails.

well, I tried to load the Sprint image from the VZW, no dice. It said it passed, but upon reboot loaded up the old Big Red (even with the Sprint SIM in it).
Anyone have any ideas? This is driving me insane....
Hi guys I got a Verizon N975U note 10 plus and its stuck on Verizon I'm trying to flash it with U1 so I can pop a sim in and changes it to that carrier. Do I just need to flash it with the U1 file here https://androidfilehost.com/?w=files&flid=297980 or will it need something special the build # is SQS2ASJ8

Can't say for sure it would work on U firmware (lack of first hand experience to verify) as it would for U1.... As long as the phone is network/sim unlocked then you should be able to just put the new sim card in it (and the phone will read the sim card settings and apply them).
Flashing the U1 firmware instructions on flashing U1 firmware have been at link below (bottom of first post). You can get the firmware from that thread also.
https://forum.xda-developers.com/showpost.php?p=80072192&postcount=1
Of course keep in mind that none of this will matter unless the phone is sim/network unlocked. As long as you meet the requirements from Verizon (or the phone was blacklisted for either non payment, lost/stolen or a warranty/insurance exchange that wasn't sent in) then this shouldn't be an issue.
its locked to Verizon at the moment when I put a sim in it will work for a bit then say its not allowed to use another carriers sim at this time.

Either wait until the phone is able to be unlocked by Verizon, or call them and request that they unlock it for you. Until that happens you will not be able to use a non-verizon sim card.
I would also advise keeping the U firmware for Verizon installed and not flashing the U1 firmware, as the Verizon sim/network unlock requires the carrier firmware... At least that is what I am gathering from various discussions/threads.

Is your phone carrier locked to Verizon? Has it been activated on Verizon's service for 30 days? If not, I'm pretty sure firmware flashing won't help anything. I'm on a Verizon MVNO and they wouldn't even unlock it for me to use on their own network. I had to activate with them for 30 days.
However, now that mine is unlocked, it's still locked down to Verizon in a lotof ways. My SIM card for my current carrier can't apply an APN, for example, so I have to do it manually. I'm contemplating flashing U1 to fix that issue (I hope).
I have a very similar situation. I bought a Note 10+ N975U (Verizon Unlocked) and I want to take it to U1 and then maybe to Sprint. I tried to go to the OP here and follow instructions. So I downloaded and selected all the files for U1 and apparently I did the "no-no" and got stopped with the SW Rev Check Fail : abl Fused 2 > Binary 1. I looked at what my phone is on and it is the SJ8 (November?) from Verizon. I'm guessing that means the BL file (bootloader?) in the U1 folder (SGO?) is older than what is on my phone? What do I need to do differently? I already tried without selecting the BL file, but it still gives the same error. Any help is appreciated! Thanks in advance!

The bootloader of the U1 firmware you were trying to flash is lower then what is currently on your phone. So yes you are correct that is the no-no. Also you can not skip the bootloader file when flashing, so that wouldn't have worked.
If you read through that thread you will have found others asking how to go from U to U1 firmware. Also the error within regards to trying to flash a lower bootloader version firmware was also asked and answered. I would encourage you to browse that thread and the Q&A forum because this process has been discussed on more then one occasion... It might contain helpful/useful info for you.
In short you need to get a newer firmware release. Using samfirm or frija apps, or the sammobile website look for the firmware your seeking. Google searching will show you how to obtain samfirm, frija is posted the forum here if I recall correctly.
For U1 the model is SM-N975U1 and the region is XAA.
Hey everyone,
I'm new to flashing phones but have experience flashing other hardware; still, I felt it prudent to ask for some guidance on this being my first attempt:
I have a Straight-Talk phone which is active and working with 4G that I would like to swap the SIM over to use in my Galaxy S10+ from Verizon.
Swapping the SIM without flashing limited the functionality to be contingent on WiFi; 4G would not work correctly.
So I suspect I'll need to flash with unlocked firmware to get it to work properly.
I have downloaded the G975U1_SAU_1.zip which is what I think I'll be needing to pull this off, as well as the latest available download of Odin (3.14.1).
Before I get started, I'd just like to ask some Questions:
Should I leave the intended SIM (Straight-Talk) in the S10+ (Verizon) while I'm flashing, or insert it after the flashing?
Am I using the correct firmware to flash this Verizon phone to work with Strait-Talk? (United States regions)
Also should I back up the intended SIM in some fashion before proceeding with this process (if so what software if any would be advisable for this?)
Is there anything I need to watch out for?
Am I on the right track for what I'm attempting to do?
Thanks in advanced for any help! :highfive:

Insert SIM after flashing. You need the current U1 firmware from sam mobile. You also need the patched version of Odin that's floating around the forums here. No need to backup your SIM, but using Odin will reset your phone to brand new. Nothing that I can think of, you just put the correct Odin file in each slot and hit go. Seems like you're onto it, you need 3 things which are patched Odin, latest firmware, and I think phone drivers so your PC recognizes the phone. Should be able to find these on Samsung website or other parts of the web.
Thanks for the support!
After your encouragement, I rechecked my firmware made sure to acquire the USB Drivers from Samsung.
Successfully flashed the phone and its now working as intended!
:victory:
I used the Frija tool mentioned here to make sure I had the right files.
And the Driver install came from here.
Thanks again for your support! :highfive:

No problem man, glad to help. Good you posted links too so others can do the same if they're having issues.
Absolutely!
Anything I can do to help pay it forward.
I should also mention I got my CSC code from the list posted at
Droid Views dot com /how-to-change-csc-in-samsung-galaxy-phones/
(Won't let me post the outside link given that I'm new)
The code was required to use Frija to download the correct firmware.
(The 4GB download averaged at 2.5MB/s)
Here is the list I saw on the aforementioned page; I used XAA
Code:
[LIST]
[*]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)
[/LIST]
Random questions:
If you start with a Tmobile GM-S975U that is carrier unlocked (got unlock code from tmobile)
Will it work just fine with straight talk? If not Does changing the CSC code work, and to which code?
Is different firmware required? like U1?

The U1 software for the S-10 plus is strait from Samsung and has no carrier bloat. All US S-10 pluses are the same, no matter who the carrier is. That means you can flash any vendors rom as long as you don't go backwards on the bootloader version. The phone gets set up by the simm card installed on the first boot. The good things about the U1 software is there is no vendor bloat and your updates come straight from Samsung. Don't forget, you have to us the customized Odin to flash with.
Deatailed info and Odin link can be found here. https://forum.xda-developers.com/s10-plus/how-to/guide-g975f-flashing-megathread-faqs-t3936704
Thanks for the reply. Should straight talk just work? My friend says data isn’t working on tmo firmware. What firmware and Csc code would work with them?
curious, do mobile Hotspot work, or is carrier still able to block it?
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!
