Question S22 ATT mobile - Samsung Galaxy S22

Hi All, I have a unlocked S22 ATT phone. Everything is working fine except that I don't get security or new Android firmware update over the air. I dont stay in US ( I stay in India) and it seems this is a major problem for ATT mobiles. My phone has a SD chipset with model sm s901u. Can I flash india specific firmware and will it work

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 ..

Can all USA Galaxy S9 models be flashed to each other's firmware?

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
Had many members flashing the wrong firmwares thinking they could do that and bricking their S7s / wondering why ODIN failed

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....

Can I flash sm-N975U1 AT&T unlocked firmware over sm-N975U AT&T?

My sm-N975U AT&T note 10+ has never ever received any updates.
It's currently at Android 9, N975USQU1AS12, security patch: September 1, 2019. Since I got it in 2019.
I see that the unlocked version SM-975U1 AT&T receives updates frequently and I can easily get the firmware online.
I've not even seen any Android 10 firmware for SM-975U AT&T.
So is it possible to flash SM-975U1 AT&T unlocked over SM-975U AT&T.
Or even just to make it US unlocked with no carrier so I can receive updates from Samsung?
You can flash the N975U1 firmware onto the N975U (and vice versa) so long as the bootloader is the same version (or higher) then what is currently installed on the phone.
Three things to keep in mind:
No way exists to downgrade the bootloader... So if you flash firmware with a newer bootloader and you decide you want to go back you will not be able too.
Bootloader version can be found by doing the following. Looking at your About Phone > Software Version look at the baseband version info.. Start at the far right and count 5 characters to the left (with the first character being the far right one). The number that is the 5th character in will be the bootloader version that is currently on the phone.
The USERDATA isn't always included with the U1 firmware should you desire the AT&T version of it. You should be able to find that in this thread,
For an example the red number is the bootloader version:
N975U1OYM3CTE7
For anything else this question has been discussed here a lot so you won't have any issues finding information about it.
So this will unlock the phone? Does the same go for the Sprint version?

You can flash the firmware from the N975U1 to the N975U (and vice versa). It doesn't matter the carrier, only the model number matters.
Just be sure to be mindful of the bootloader version.
Flashing the firmware from the N975U1 does not have any relation to the network/sim lock. For network/sim unlocking you will have to ask your provider to do this for you
The term (or name) "unlocked firmware" is derived from the phone it comes from.. The N975U1 is the carrier/network unlocked variant sold by Samsung.
so if i put the, U1 firmware to n975u and i'm out USA. now I will receive all the new updates automatically via OTA?
Excuse me, I am new to the forum, I have a question for you, I have an at & t SM-N975U, this at & t firmware does not update outside the USA, I am in Mexico, which firmware should I use, I want it to update automatically via OTA here in Mexico? t-mobile firmware or U1 firmware, I really appreciate your answer,
hello, my question is similar but regarding the carrier. My Note 10 Plus is AT&T locked, if I flash the SM-N975U1 over the SM-N975U, will that unlock the carrier so i can use anyone outside USA?
No. It won't. You'll have to have AT&T unlock it.

Hello can you please help me too
I'm super new here
So i have the N975U and i live in Europe and i don't get any updates cuz my Note 10+ is the AT&T version and now i want to change it to N975U1 so i can get updates from Samsung themselves.. from Sammobile i downloaded The N975U1OYM7GULD-(XAA) model and also N975U1OYM7GULD-AT&T model while the current one i have is N975USQS7FUI7 so both of them i think should work because they have the same bootloader so my question is since i want to get updates to which one should i flash my phone with? I heard the XAA is better because u get updates directly from Samsung themselves ( even when I'm in Europe ) and the AT&T version is also N975U1 but I'm not sure if i will be getting updates because now I already have the N975U ( probably AT&T model that's why I'm not getting anything ) So what do you think i should do?
I'd appreciate ur help
And sorry for my broken ass English hope you understood..

And should i use Odin patch or just the normal odin? I actually wanted to flash my phone with the Germany version but i don't know if it will work!!? ( You'd use odin patch you want to change region! ) so idk if it would work if i change it from N975U to N975F which is Germany model !!?

Change Modem (CP) for G981U1 for use in Europe?

...because I use the phone in Europe. Given the firmware is North America I was wondering whether I need to change the modem in ODIN to get better reception/ 5g in Europe. The last Samsung I owned was the S4 where updating the modem to your region was ubiquitary. Not sure if this is still necessary and doable., so hoping for some advice.
Second question: I have a US S20 locked to AT&T. Will flashing the U1 firmware (incl. factory reset) also unlock the phone?
Cheers!

You can't mix exynos firmware and Snapdragon. I doubt you can use just the modem portion of a European exynos code. You can flash U1 code freely, but that does not unlock the bootloader. Do you mean you can't put any sim other than AT&T?
I didn't mean to unlock the bootloader (since that's not possible for US phones) but the sim so I can use my German sim card in Europe in this phone.

Do you know if I run the risk to brick my device if I tried to combine the exynos modem with a snapdragon rom? Cause otherwise I might just try it.

Question SM-G990U1 firmware on SM-G990U?

I have a paid-off Permanent Unlocked SM-G990U from T-Mobile. My carrier is US Mobile on the Verizon Network (CMDA). It does work on the T-Mobile Firmware but there is no Wi-Fi calling, MMS works but I can only receive MMS (can't send). It's not actually connected to CMDA according to AIDA64 and yet Verizon somehow still works, and also there is T-Mobile bloat, and software updates are slower than on an unlocked device. Even though the U1 has 2 sim slots but the U doesn't and the U does not have an unlocked firmware from what I know, would the U1 firmware still work fine with Cellaur and etc on the U fine despite having only 1 SIM card slot? Since I'm pretty sure the hardware between the U and U1 is the same otherwise.

I've flashed U1 unlocked firmware on U carrier firmware before (S9+ days) so I'm thinking it still should be possible on modern devices, though you need patched Odin to do so (search for it on XDA/Google)

I will probably most likey back my data up try it to see if it works, if not then i can just revert to normal firmware
You can flash U1 rom without any problem. My device is from Verizon and I flashed successfully the U1 firmware. You will just need to choose correct CSC for your carrier
