AT&T model and lack of updates - Samsung Galaxy S10+ Questions & Answers

Hello. I wanted to ask about a problem that I have experienced with the S10+, which I know others have experienced as well, and hope there is a solution out there for it. I purchased the S10+ directly from Samsung, as they were offering a much better trade-in deal. However, I did purchase the AT&T version.
That being said..aside from the 2 fingerprint reader updates Samsung has issued, I have never received an OTA update from AT&T. Not a single one. I've had to come here to XDA, hope that someone posts the latest update files, and update using Odin. It appears that those files are being posted less and less. I'm "stuck" on ASGB update, with the July 1 Security patch.
Does anybody have any advice, or suggestions on how I could go about getting regular OTA updates? Or is there other recommendations on what to do here? I know there are many others that have this same problem.
Thanks in advance

Are you using an AT&T SIM card? If you purchased an AT&T model AT&T sends OTA updates whether you got it from AT&T or Samsung. If you aren't using an AT&T SIM they won't send you any OTA updates and Samsung only sends OTA updates to the carrier free versions of the phones.

Yes, using an AT&T SIM card. In fact, I went to the local store and requested a brand new sim, just in case. That obviously didn't work either.

All US S10+'s are the same. There is no such thing as a AT&T or Verizon phone on the S10+. That being said you can load any rom from any vendor on your phone. If you want to stick with AT&T and don't mind their bloat apps you can go to www.sammobile.com and download the latest AT&T rom and load it with Qdin. Make sure your sim card is installed when you reboot and you will have an AT&T phone when it is done.

Prior to August or September firmware on the S10+ was not all-inclusive. If you used an unlocked AT&T S10+ with a different carrier's SIM the AT&T firmware stayed rather than updating to accommodate the inserted SIM card. AT&T doesn't send OTA updates to phones running AT&T firmware if a non-AT&T SIM is inserted and as long as the AT&T firmware is installed AT&T is the only place you can get an OTA update from. You can't even update with SmartSwitch because it will show that you have the latest firmware regardless of how old it is.
I purchased an unlocked AT&T S10+ in early July that was on the February security patch and have a T-mobile SIM. The only way I could get software updates was to manually flash the U1 carrier free firmware with Odin. Immediately after flashing that firmware multiple OTA updates showed up for my phone.

AT&T offers a modded version of SmartSwitch that you can download from their website. You might be able to update to the most current AT&T firmware using their software which is called AT&T SmartSwitch. The standard Samsung SmartSwitch program doesn't access AT&T servers and won't update phones with AT&T firmware.

Why did I have to pick the carrier when purchasing the phone via Samsung? I could have selected the unlocked version, or any of the american carriers. I have the AT&T model. I see the logo when I boot up, and have all their bloatware apps. So that's not the issue. The issue is why haven't I received an OTA update, ever?
I use this threadhttps://forum.xda-developers.com/galaxy-s10/how-to/att-ota-ota-updates-t3909697 to manually update. The OP hasn't posted any new versions in a while.

Your OTA updates come from AT&T since you are their customer and purchased the AT&T model instead of the carrier free one. You should really be asking AT&T why you aren't receiving OTA updates.
You might be able to update using AT&T SmartSwitch which you can download from AT&T's website.

I've tried contacting AT&T numerous times. They have no idea what the issue is. A quick google search shows the Smart switch tool in AT&T, but when you try and click on the link, it just takes you to a blank page.

Newer firmware is all-inclusive so you could download firmware with Frija and flash it with modified Odin even if it isn't AT&T firmware. The problem is that if you flash a build number AT&T didn't actually use on their devices you still won't get OTA updates from AT&T because their servers won't recognize the software version you are running.

Have you tried the standard Samsung SmartSwitch program? Maybe it can update AT&T firmware now but it didn't in the past.

If your phone is not carrier locked you could flash the U1 firmware and then you would get OTA updates from Samsung instead of AT&T. But you might not have access to some AT&T services like visual voicemail without AT&T firmware. AT&T also hates unlocked phones so it's possible Volte and Wi-Fi Calling will stop working. Some AT&T customers with unlocked phones were able to get the services activated by calling AT&T but success with AT&T Customer Service is hit or miss at best as you already discovered.

I have the same problem I have been able to update my S10 + AT&T through ODIN, because I cannot update using FOTA, I have the September security patch specifically "G975USQS2ASI6", I want to update to the October patch, but I do not receive the update via FOTA, because I do not use AT&T SIM but I am abroad using with another SIM.
I can Flashear with ODIN to the U1 version that is unlocked, I will not have any problem, I am not interested in losing any AT&T service because I do not use any, I just want to have my S10 + free of Bloatware and always receive updates via FOTA.
I found this Firmware is Sammobile "https://www.sammobile.com/samsung/galaxy-s10-plus/firmware/SM-G975U1/ATT/download/G975U1UEU2BSIP/298471/"
It is the most recent update of AT&T that they have on the official website, but it is G975U1 unlocked and not the G975U. If Flash this version will I have any problem freezing or ruining my phone?

No G975U1 and G975U firmware are interchangeable. If your phone was still carrier locked you might get a message asking for the unlock code but you aren't using an AT&T SIM so your phone obviously isn't network locked. I went from AT&T G975U firmware to U1 firmware with no problems.

Im glad I'm not the only one experiencing this. My wife and I did a bogo deal for the Galaxy s10+ back in March. My phone has recieved updates regularly, while my wife's phone is still on the March patch and security. She hasn't even recieved the fingerprint update fix. Tried calling AT&T about it and they were totally unhelpful. Told me I had to contact Samsung about that and that they couldn't help with the issue. Im debating on calling them back and trying to speak with someone more knowledgeable, but it might just be easier for me to update her phone manually. I haven't had to do something like that in ages, so I wanted to ask for some guidance on here.
Would i need to do each consecutive update she's missed manually? Or would just updating to the newest firmware outright do the trick?

Hey do you have the G975USQS2ASI6 ODIN files? I have been looking all over for it to flash it to my phone.

I just want to note, I am also in the same boat and it's INCREDIBLY frustrating. Both phones purchased in March with the BOGO deal, both phones stuck on the July 1st security patch. Supposedly what I've found after reading quite a bit is you can bring the phone to a local samsung repair center and they can flash the newest firmware, once you're up to date SUPPOSEDLY that resolves the OTA stuff. I don't believe it though.

Won't search for latest OTA updates

Hi, I bought a Galaxy S7 edge sm-g935a, and I'm using it here in Japan with other network. I'm just wondering why everytime I check for an update, it always says I'm on the latest firmware even when I'm like 3 or 4 versions behind. Even when I connect it to smart switch it also says I'm on the latest firmware too, and when I try to click on firmware upgrade and device initialization, it says "Galaxy S7 Edge does not support initializing, please contact customer support". What should I do to get OTA updates? Thanks
AT&T phones will not receive OTA updates if you're not on the AT&T network. You have to manually flash them. You could keep downloading the latest firmware and flash it, or you could download the U firmware, which will receive updates regardless of carrier.

I'd consider switching to the 935U Firmware, it kills the useless AT&T bloat, and you'll get OTA's

Thanks man, I tried searching for its latest firmware but none of it seems to work out, I found some on google and download it but when I tried to unzip the files, all the files that I've downloaded we're corrupted LOL. I'm now switching to 935U firmware :good:
My S7 edge won't update either. I seem to be stuck on the May 2017 security update (Build # G935AUCS4BQE1). I bought my phone from swappa.com last month. The seller had it listed in the AT&T section as the SM-935A. I can use it for the most part without any issues (no Wi-Fi calling, not recognized on the AT&T network). When I check the IMEI # with Samsung, they show it listed for Sprint. Any suggestions of what I should do? I know one option is to flash the 935U firmware.
Thanks in advance.

All US (Snapdragon) based S7 Edges are physically identical, so you can run AT&T firmware on a Sprint S7E and vice-versa. However, AT&T is well known for disabling features based on IMEI, which it appears they are doing for WiFi calling. Unfortunately, it appears someone converted a device that started life on Sprint, so unfortunately you may be out of luck. The only way to fix the problem that I am aware of is to temporarily switch your SIM out for an actual AT&T device (whose IMEI is recognized), and that supports WiFi calling and VoLTE, then put the SIM back in your converted S7 Edge.
Converting to U will definitely make the phone a LOT faster (and the battery last longer), but you are giving up on any carrier features period at that point. I personally felt that the performance and battery features were a lot more important to me than WiFi calling or VoLTE and I switched to U a while ago. I haven't looked back, but that's just me.
Thanks jshamlet. I did a chat with Samsung and they confirmed that my phone was originally setup for Sprint and that it has been unlocked. My fiancee has an AT&T branded S7 Edge, so I can try putting my SIM in her phone for a bit. Converting to the U is something I'll seriously consider. I had an unlocked Moto X Pure Edition, so I'm used to not having the Wi-Fi calling or VoLTE.
I ended up using Odin to flash the SM-G935U firmware to my phone. Once that was finished, it downloaded and installed the April - August security updates, so I'm happy now. Also, no AT&T bloatware.
Here are the Firmware updates for the ATT 935A.

ATT unlocked G950U is not updating. Stuck at April firmware

So I got an ATT S8 the G950U version. I unlocked it via ATT with their unlock code.
since then using it on Indian carrier Airtel. I am not been able to get any software updates. Whenever I check for the updates it says its up to date. But its stuck at build number G950USQU1AQC9 and security patch of 1 march 2017.
How do I update this? Do I need to flash ATT software via ODIN? but I need to retain the unlocked status.
You wont get OTA unless you have an ATT sim in it i Think. Just flash G950U1 firmware which is the unlocked version sold by samsung.
I bought a sprint s8 and flashed G950U1 firmware and using on Airtel. Moreover you wont have any carrier bloatware.
It seems Smart Switch also updates when applying initialize. Not connecting your phone before starting up SS gives you the option to input model - and serial #.
And to my knowledge, once unlocked (free to use any SIM) stays unlocked.

Did you flash it with Odin? AFAIK its the only way for snapdragon models. Been away from android tinkering for a long while. Can you point me to relevant threads?
P.S. Are you able to get OTA now?
I have a similar issue but in the UK. Can't see OTA updates and it says up to date in Smart Switch. Is flashing the stock firmware risky or break knox? What are my options?
Search Updato.com for the latest G950U1 firmware. (XAA version is the best region to use in your case). Use THIS version of Odin to flash: http://dl.psouza4.com/android/Odin3_v3.12_PrinceComsy.zip
You will not get updates normally if you don't. Your phone is trying to contact AT&T servers but you don't have their sim card so it's not going to let you download it.

Be careful, the latest u1 firmware is a rev2 bootloader. It will probably be rootable like the n8 one is but no one has confirmed yet. There are also no ready to flash rooted ROMs with it
Root is worthless anyway.

Not getting S8 software updates and getting errors (urgent) help plss

What kind of s8? Is it through a carrier? I have the same problem with AT&T branded. I called AT&T and after they tried to push the update to my phone after getting my IMEI and SIM info verified, nothing happened. They referred me to Samsung. Samsung said I could drive to a Best Buy an hour a way and they could load the latest software in the store. In other words, no one really is accepting responsibility for it. I am basically at the point now where I've decided to flash the updates myself.

I'm by no means an expert, but as I understand it, all carrier branded updates go from Samsung to the carriers and from the carriers to your phone. Only unlocked comes from Samsung to you. (anyone feel free to correct me if I'm wrong).
If your carrier isn't pushing the update to you it could be because the carrier is not sending you the update because of the SIM issue if there's a mismatch in their system. There may be other reasons too, but that seems to be a common one.
Otherwise if you want to update firmware and it's not being sent to your phone, I believe the only alternative is doing it yourself. Check this forum for more advice.

That firmware AQDG is old, from like April this year. You can download a different firmware or an updated UK firmware from updato.com and update with Odin. Knox will not be tripped.

Upgrade old firmware on VZW unlocked phone to ATT

Hi,
I'm a little confused here. I want to upgrade my firmware on an unlocked S8 I bought SM-G950U and it's currently running G950USQS2BQL1 which is VZW FW but I have att as a provider.
To update my firmware do I flash VZW FW or can I flash ATT FW? If I'm able to flash ATT will updates be pushed OTC from now on? Also is there a way to upgrade without wiping the data? Lastly, can I update straight to Oreo (one again without losing data?) The OTA function never provides any updates.
Thanks.

Flash the US XAA firmware and you will get rid of all the carrier bloat and get updates straight from Samsung servers.
If the S8 is unlocked then you can just pop in the Verizon sim and it'll ask to reboot and then you'll have the ATT FW.

What month security patch are you on? If its the November or later it should switch to an ATT S8 after it asks you to reboot. If its earlier then yea you'll be a verizon(doesn't have to be active) sim to get it to take the OTAs to being you speed, and then it'll change to an ATT S8 after asking for a reboot.
Edit: You don't have to flash a different carrier version, it'll change itself on the newer FWs to match whatever sim is in the phone.

AT&T Branded S8 moving from AT&T service to Verizon

Hi,
I have read through a bunch of threads but have not seen my exact situation but I think I know what I have to do but want to get some advice from the experts here.
I purchased an AT&T branded phone an activated on AT&T a year ago. We needed to switch to Verizon so I got the unlock code from AT&T and switched no problem. As part of the switch Samsung has a BYOD feature that changes some of the software and menus from AT&T to Verizon. It was actually pretty cool because it removed the ATT apps loaded some VZW instead. Below is a link that describes the feature if you are not familiar:
Enjoy the Freedom of BYOD
So all is mostly good except I believe the menu change to update the firmware OTA is pointing to VZW and not ATT. When I run the update check it just says no updated needed. Looking at VZW they have updated their latest OTA version on August 1st here G950USQU5CRH1 so I know it is not trying to update to that.
ATT just released their version today August 30th here G950USQS5CRH1 but that is not updating either.
I will try this again over the next couple days to see if the updater is smart enough to find the ATT version but I am guessing I am probably in no man's land and will need to update manually using SamMobile or Updato or something else.
Any thoughts are very much appreciated.
Thank you.
I have tried a number of things like all the Verizon tools, Smart Switch, etc. and nothing will trigger a download.
I am downloading the only file from SamMobile that looks like the same version on the AT&T site but is says it is Verizon hopefully that will not matter. I will try to flash it with Odin and see what happens.
As an alternate I chatted with Samsung and they gave me the address of the a Best Buy in my area that will update the firmware for me. I guess some of the BB have Samsung techs in them. Kind of a pain but at least there is a back up.
Not sure if anyone is following this but I thought I would close this out. All options have failed.
Not even Samsung at Best Buy can flash the firmware since in their tool my phone shows up as VZW/VZW/ATT. So what I thought was a cool feature of the BYOD changing carriers only cripples the phone from an Update perspective, what a bad design. I would change carrier firmware as in some of the guides here but the problem is that I do not have G950U1 or G950U2. I have G950US which the older guides do not address.
I am either going to buy a prepaid ATT card but I hate to give those horrible people another dime or I will sell this phone and maybe just get Samsung branded like others in my family and they get updates from Samsung or go get an iPhone. I dislike iPhones a lot but at least Apple does not let the carriers screw around with their firmware.
Solved! Not sure why this site never showed up in my previous searches here or on the web.
https://samsung.firmware.science
Found the latest 2 OTA updates and applied them perfectly.
Well I can't say I've ran into this problem, but I to use ATT and am looking to eventually move to VZW, so I really appreciate your time and effort in making this thread as this isnt something I would have thought of myself. Also, that website is kick a**! thanks for sharing that
I was an ATT customer for 14 years on my wireless. The migration on the family 2 iPhones, 1 Samsung unlocked S8+ and my ATT S8 went perfect. I am the only one that had the firmware update problem because the other devices get updates directly from Apple of course and Samsung for the S8+.
My experience so far with VZW is excellent! For our family plan it was a little cheaper but our main reason fro moving was the network quality. Verizon in my area is so far ahead of ATT it is really shocking. Great call quality and data and coverage is fantastic. We had so many problems with ATT not sure why I stayed so long. They gave me a piece of junk Microcell to try and fix the issues at my house but even when we go to the ATT store that is 1 mile away, they do not even get wireless service in the store. They all have to use WiFi calling.
I have to really be impressed to recommend a company but VZW technology is well worth it for me. We will see how the rest to the customer services is.
What happened with the firmware you flashed with Odin? You can go to Updato.com and Download G950U or U1 firmware which is MUCH faster than the hours Sammobile takes. With newer firmware you can flash any carriers firmware (Go to Updato and download VZW firmware for example) because your phone installs the necessary files depending on the sim card you're running. Been that way for quite a while now.
Be careful with Firmware science as some of those builds aren't what is released so when a newer update does drop from VZW you wont get it again because you have a conflicting build number. Then you'll be back here asking why. Also, every time there's an updated firmware on FW Science you'll have to reinstall everything as flashing that update.zip wipes the phone post install. It gets really old.

Hi thanks for your input, I have 1 question to you, as I understand from your post you are talking about if mobile is already on VRZ firmware but have issue with OTA update? am I right? if not could you be so kind to tell me I'm on AT&T firmware G892AUCS3BRG1 (AT&T OREO Firmware) can I somehow switch to VRW or some other carrier? in addition, I have no Verizon sim and no AT&T sim as well I'm in Georgia and in our area, there are no such operators.
from my perspective it is good to have TMB firmware this would be the best option for me if it is possible
thank you in advance for your cooperation

When you flash firmware it installs carrier files based on the Sim card in your phone

If you install a different sim card it will basically switch to that carriers firmware
