Where can I find At&t Official Android 11 Rom? - Samsung Galaxy Tab A series Questions & Answers

I have the Tab A 8.4" At&t variant but no LTE service on it. It came with stock Android 9 and Android 11 is out for it, but since I have no service, I can't trigger the update OTA. Anyone know if there is an Official Stock Rom for it that I can flash?

So I have At&t Unlimited Elite and I tried this just for fun. I took my SIM out of my phone and put it into the tablet. Well it has service from At&t but can't trigger the update, still keeps saying already up to date on Android 9.

Why didnt my phone get nougat?

I recently bought my s7 edge directly from the samsung website at&t version and got it unlocked to be used on the tmobile network. I tried updating the phone to nougat but at&t software update would say that I am on the latest software which was 6.0.1. I even used a working at&t sim card because I thought maybe you need to be on their network but still it gave me the same thing. Finally I just used odin to update to nougat but I wanted to know if anyone knows why I was not able to update ota?

You are on the international version if you bought it directly from Samsung. They haven't released the international N for the S7 Edge. I know this is frustrating but you aren't the only one. If you can put up with ATTs bloat then go flash the Odin files, they have been released for ATT.

Android Oreo Update

1. I unlocked my AT&T Galaxy S8 and switched my carrier from AT&T to MetroPCS. As soon As I did that MetroPCS is wanting me to install the Android Oero Update. Is there any way to hide the notification and keep it from prompting me from upgrading?
I am on the Snapdragon version of the S8 so Rooting is not possible.
2. If I do decide to update, Will this change the bootscreen from the AT&T logo to MetroPCS logo?
3. If I decide to update and I don't like Oreo, Can I go back to Nougat?
I believe there is a service you can stop that will keep the update notification from popping up but I don't know what it is. You should be able to Google around and find it.
I did this exact thing (original AT&T phone unlocked and put a MetroPCS SIM card in). Yes it changes the AT&T logo to MetroPCS switch is unfortunate when considering reselling your phone I think.
I doubt you will be able to go back to nougat once you upgrade to Oreo. Maybe if you root the phone which I stopped doing to my phones.
With newer firmwares it installs carrier files and bootscreens based on your installed sim. Install another sim you'll have a new bootscreen.
You can always just Odin on Unlocked firmware and not worry about any of it.

AT&T S8+ won't update after unlock and carrier switch

Sorry guys, complete amateur here. I have an AT&T S8+ that was unlocked using a code from AT&T.
I switched to T-Mobile and my phone worked perfectly after simply inserting a T-Mobile sim.
Carriers push updates over the air and I assumed I would have put in an AT&T sim to get the oreo update, but it's been out forever and I have not been able to update my phone. I've been busy and never got around to it. My phone was working fine so I just it slide.
I've tried using an AT&T sim. I've restarted my phone with the AT&T sim in it. I've tried manually searching for the update. I've tried smart switch. I even went to the Samsung experience store in NYC and they had no solution. My phone will not update.
Any suggestions?

I've been reading some of these threads and I'm not sure if this is correct, but I can use Odin 3.13.1 to flash to CRB9? That would get me to the first Oreo release?
Sorry if this is not the correct place for this thread. Thanks

OTA Update Not Available Galaxy S8 Active (AT&T SM-892A)

As far as I am aware the AT&T Galaxy S8 Active is supposed to be compatible with Android 9.0 (Pie). I just bought an unlocked version of this phone on Amazon and it is currently on Android 8.0 (Oreo). This is the baseband version: G892AUCS3BRG1. I have tried flashing the update file from this post, but I kept getting a PIT error. I also tried using Samsung's Smart Switch, but that also says that 8.0 is 'up to date'. I don't plan on getting an AT&T sim and the phone currently has no sim. Now that you know the information here is my question: How can I update to 9.0 without getting an AT&T sim? The best solution would be a working 9.0 Flash for my device. Thanks to anyone who figures anything out.

AT&T S10+ hasn't received any updates!

Hey everyone. So back in March my wife and I both got new S10+s. I noticed recently that my wife's phone hasn't recieved any updates at all since she got the phone! Shes still on ASD3 firmware, March Security patch, etc. I don't think she's even gotten the fingerprint sensor fix update because her sensor is a pain to use compared to my phone. My phone has been updating regularly.
I tried calling AT&T customer support and they were pretty much useless. Any recommendations? Should i just look up the updates on XDA and flash the phone to the newest patch myself with Odin or something?
That's very odd given the phone forces updates by itself. Make sure your wifi connection is good. Try going to settings and manually clicking on software update. If that doesn't work just download the firmware from XDA here and flash it with that special version of ODIN. Due note that by flashing thru ODIN it will erase everything I think like a factory data reset does.
Is your wife using an AT&T SIM? It's probably a dumb question but AT&T doesn't update phones with their firmware if a non AT&T SIM is being used. It has to be actual AT&T - - they won't update if the SIM from an AT&T MVNO like Cricket is installed either.
If your wife has AT&T but different service plan as an experiment you could put your SIM in her phone and see if any updates show up.
Your AT&T S10+ should be on G975USQS2ASl6 latest firmware with Sept. Security. Do not know why it does not Auto update as mine does on Wifi.
My wifes tmobile one has the same issue, stuck on June patch. I'll be odin flashing it this weekend.
