Sim unlocked but OTA updates not - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

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.

You MAY need to be on AT&T's US Network to receive OTA Updates but you should have no problem making and receiving calls and texts in Mexico.

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!

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!

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

g975U1 August security patch ASGF update released

Got notification this morning for a 217mb update ending in ASGF. Pretty weird since we just got the July patch only two weeks ago, after not getting an update in over two months. Definitely not complaining though! Sorry if repost
I don't see that update on my G975U1
I got it too. August US unlocked
Just got the update!
is available via samfirm
Unfortunately i just switched over to carrier firmware for faster updates. Now Samsung finally does it right. At least carriers should be releasing it in a week or two.
Sent from my SM-G975U using XDA Labs
Whats new in this August update?

No idea. There are no details listed on the Samsung website or in the notification popup. I mean the security patch has been brought up to date (August) but other than that, I can't say.
Got the notification today.... Hopefully someone can breakdown what is in the update because 200+mb is rather hefty right?

I believe you have been misinformed. Please be patient and wait for the update to show up on your phone if you are already on U1 firmware or download the latest U1 firmware using Frija and Odin flash. All the very best.
Update is due to a exploit in the chip. Some one can take control of our phones if we are on the same wifi. Kudos for the fast update.
I updated and now I don't get icons on my lock screen for notifications. Anybody else have the same problem?
975u1 August Firmware Patch T mobile
Hello,
I have a US unlocked 975u1 and use Tmobile. No one seems to know what I am talking about with an Aug Update. I have spent time on the Phone with Samsung and Tmob customer service. Stuck on July patch ASCB. Night mode is still disabled. Samsung Switch has nothing on it as of this morning.
How do I get the firmware everyone else is on? If I get a sim card from another carrier, does that sim need to be activated in order to get the latest patch? I am clueless here.

U1 firmware with the August security patch and Night mode is available and does end in ASGF.
Unless you flashed T-Mobile firmware on your U1 model or you purchased an unlocked U1 with T-Mobile firmware already installed (I'm not sure how to check that in the settings but U1 firmware doesn't come with any T-Mobile branded apps) you should be receiving OTA updates from Samsung rather than T-Mobile.
The U1 OTA update was pushed weeks ago making it the only OTA update we received before the carriers.
If you have T-Mobile firmware you could flash the U1 firmware manually and receive OTA updates from Samsung but you will lose T-Mobile branded apps that aren't available in the Play Store. The U1 firmware has also been receiving updates long after the carriers prior to August--in early July we were still on the May security patch.
If you manually flash VZW or SPR firmware as the other member suggested don't flash the User Data partition or you will also get Verizon or Sprint's apps and bloatware. If you do manually flash either of those you will no longer receive OTA updates and will need to keep manually flashing updates in the future.
So I bought my phone directly from Samsung. USA version with snapdragon processor and its non-branded to any carrier, basically an unlocked Galaxy S10+. Its model number is sm-g975u1. Sim card is from Tmobile, my cell phone carrier.. I have software from July 1st, g975u1ueu2ASGB
What do you recommend in my scenario.
Thank you

Sm-g975u need help switching att to tmobile

sm-g975u unlocked att phone wanting to change to tmobile. I have a tmobile sim and had originally plugged this in. The phone works fine but I recently noticed it has no Ota updates occurring. I would like to load tmobile firmware on it to enable some of the tmobile features as well but primary concern is ota updates.

When I try says fully updated when I put it on samsung switch it says fully updated
Can this be done?
What firmware do you suggest?
Csc *#272imei#(may have that wrong) but is recognized and does work not sure when and what to use here, many options.
Also, not sure of the answer here, but if I run an update or csc change (the phone is unlocked) would it require me to unlock it again for any reason?
I am trying to get the phone close to a tmobile if that is possible
Thank you in advance if i need to give more info please let me know.
Download the firmware of your current network and flash you will begin to receive updates. However you can also flash the unbranded one which is G975U1 and you will still receive updates too
Can you give directions on how to get the firmware for the current network and how to flash the phone? I have an SM-G975U that is on SPR that I need to get to ATT so it will get updates from cricket. I have found a lot of materials on the internet and not a single one shows all of the steps clear enough for me to risk blowing up my phone. I have found the SPR files and TMK, and USA, and TMB, but no ATT.

Question flashing global firmware to unlocked AT&T S22

Hi everyone,
I am planning to get an unlocked S22 (AT&T unlocked, fully paid off) from the USA to my country (India). The box says it is following:
Model: SM-S901U
S/W: S901USQU1AVA7
Even though it is unlocked, i can see the SM-S901U does not support 2 5G bands which are used my in country (unlike the generic unlocked SM-S901U1). My question is that,
1) Since the s22 is basically from samsung, with the carrier models having control over the software, will i be able to flash to the generic unlocked firmware and model SM-S901U1 and get support for the other 5g bands too (i see the generic unlocked version SM-S901U1 has the 2 other bands that i need)?
2) Will the hotspot work and will i be able to recive OTA updates?
3) And the main question, will i require an AT&T SIM for the flashing process?
I was digging around the ultra thread for some info:
OTA and Non-OTA Firmware for S22 Ultra SM-S908U and S22 Ultra SM-S908U1 Versions
See Post #2 and #3 for the Links to the Firmware All of the firmware posted here can be flashed on any U or U1 Device. Each of the firmware's are NOT carrier dependent and only has carrier labels listed in order to have an idea if you might get...
forum.xda-developers.com
If someone can help/guide me, i'd be great!
Thanks and Cheers!
1. You will be able to flash s901u1 firmware (you will need a patched version of Odin to do so) but it still will not have the 5g bands, it's a hardware thing.
2. Hotspot will still work and you will be able to receive OTA updates when on s901u1 firmware.
3. No you will not, even when the phone is locked you will still not require a sim

Thanks for such a quick reply
I had thought that the bands were locked via firmware (was hoping that samsung gave control to the carriers to control the bands via software). Sadly that doesn't seem to be the case
Since the s901u1 has those bands available (i checked here: https://devicebeast.com/devices/samsung-sm-s901u1-galaxy-s22-5g-uw-dual-sim-td-lte-us-256gb), i guess that will be a better buy for 5G.
