I have rooted this phone, flashed TWRP Recovery and Flashed an unlock zip package which modified the baseband frequency of the phone with sprint. This modded unlock package is suppose to allow using the phone outside the USA...is for blacklisted phone of this post ONLY. But I haven't left the USA to test it yet. I return to Yucatan, Mexico in 5 days and will update this post...
If it works, contact me and I can direct you.
:good:
I hope to see if I can unlock. Any event notify them. Likewise if you manage to direct me how to do it please
Hi this is my first post here I'm trying to find the right firmware to unbrand my phone. I'm in London and I bought an unlocked AT&T phone a guy from Gumtree.
1. After connecting my Gear VR it says that software update is needed
2. Then it checks with AT&T for software update but it says it already the latest software. Is it because I'm in Europe it doesn't allow me to see the update?
3. Now it says to wait 24 hours before next check(ridiculous! What kind of rubbish servers they have???)
How to:
Remove branding and get pure Samsung soft without this AT&T rubbish overlay
What processor is in this phone? I think it's Snapdragon but still I'm not sure and I don't want to brick this phone
More about the phone:
Model: SM-N910A
Android: 4.4.4
Baseband: N910AUCU1ANIE
Device name: My little pony
Kernel version: 3.10.0-2771708 [email protected] #1
Build number: KTU84P
Security enhancement(I guess something to block you from unblocking): SEPF_SAMSUNG-SM-N910A_4.4.4_A019
MOD EDIT: Please read forum rules. There is no selling/trading/buying on XDA. Use swappa.com
Can't unbrand because the att note 4 is boot loader locked and unrootable at this time, but you can flash the stock update manually through Odin.

I couldn't find that file. Where have you seen it? I ordered another Galaxy Note 4. Lol first I bought was counterfeit and still waiting for a refund, second AT&T being useless ATM (I only care about gear VR), third from a company on amazon with 1 review, hopefully this time I'll be lucky.
I currently have the US s20Ultra unlocked model on ATT (don't foresee changing carriers). Currently I am missing features like VoLTE and VVM. What other features would I be missing if I stay on the unlocked firmware? Can I flash the ATT firmware to get those missing features? Can I flash back to unlock?
Thank you
What's the CSC on your device?

I am not sure what I am looking for. Its currently on ATT/ATT.
Open your dialer, enter *#1234#, press the Dial Icon. You'll see CSC: G98??, the next 3 letters will be your device's CSC Code. Your Service Provider's CSC is "ATT" which is different than the CSC in your device. Whether or not you can change the CSC depends on your device's CSC. Device firmware is always configured for the specific, original CSC or Multi CSC's.
This post may be the best workaround.

Your device has Multiple CSC's which are included in OYM so you should be able to change your CSC to ATT, which is the CSC for AT&T.
Go to "Settings" then "About phone". Write down your IMEI Number. Open dialer and enter *#272*IMEInumber# (In the thread replace IMEInumber with your actual IMEI Number). Press the Dial Icon, you should see a screen with the list of available CSC codes for your device. Select ATT and tap the Install option.
Be aware your firmware isn't AT&T, it's unbranded so even if you change the CSC, full call functionality may not be available. You can obtain AT&T's firmware at SamMobile.

Varcor, thank you so much for all the directions.
As it stands right now, it is already on ATT. Once I flash over to the ATT firmware, would I be able to flash back to an unbranded one in the future, for whatever reason? Additionally, do I have to stay on the ATT firmware to retain those features? Or could just having my phone communicate with ATT at least once with my "branded" phone and then flash back retain those features?

You're most welcome. Yes, flashing back to unbranded won't be a problem. I don't think you will be able to retain the features if you go back to the unbranded firmware, it's not configured to allow full call feature functionality. Also, after flashing to the AT&T firmware you may need to contact their CSR for external programing. Good luck!
S20+ AT&T
Hi Varcor,
I'm new in this firmware things. I'm from Singapore and has been using S20 Exynos, but due to the extreme heat, bad battery life,etc. I've decided to import S20+ Snapdragon from AT&T, according to the Service provider SW ver information, it's showing as SAOMC_SM-G986U-OYN_ATT_QQ_0023 (I believe this means the set are unlocked).
With that said, I noticed that the software is outdated and the security patch level is on February 1,2020. when I referring to the AT&T website, It's showing as the latest software is QP1A.190711.020.G986USQU1ATE6 (June update) and mine still on QP1A.190711.020..G986USQU1ATAW (February). My CSC is G986UOYN1ATAW.
My question now is, whenever I tried to hit the software update, it's keep telling me that my software is up to date. Is there's a reason why it's wont detect the update? If it's because I'm in Singapore not US, then there's no choice that I need to flash using the firmware from Sammobile. The problem is which one that I need to download as AT&T carrier is not listed there. There's only T-mobile, Sprint, Unknown, USA. Please help.

I would reach out to SamMobile and inquire why they're not listing the AT&T Firmware Update. You state your CSC is G986UOYN1ATAW. That CSC is also associated with T-Mobile. You're not using an AT&T SIM Card, correct? On a Multi-CSC Device when you insert a different SIM, the device should update to the correct Service Provider. If you're using a SIM from a Service Provider other than AT&T you probably won't receive AT&T Software Updates, which are distributed by Samsung, not AT&T via OTA.

I did try to reach them, but for some reason they are giving me some irrelevant answer. Something like "You probably don't get OTA-updates (otherwise you got them already from AT&T)". We are having a conversation breakdown there, I think they are not an english speaker (or my english is just bad). Really? that CSC is associated with T-Mobile? now I'm getting more confused because the box is stated AT&T and it's sealed.
I'm using Singapore SIM card (Singtel), so you were saying this set I'm using right now is a Multi-CSC device? If i were to flash to the other carrier firmware, will it create any problem?

Flashing Singtel Firmware won't work since it's configured for the Exynos SoC. Multi-SIM Devices have only regional Service Providers available, you don't have Singtel as an option in an AT&T device. Based on your situation I would consider one of two options. The first would be insert an AT&T SIM just for OTA updates. Not sure if you received an AT&T SIM when you purchased the device, if you didn't they're not hard to find. The second and likely best option is sell the device and purchase a Global Variant with a Snapdragon SoC, you'll receive updates regardless of your Service Provider. If it makes you feel any better there's lots of users in the same predicament. They want the Snapdragon device in regions selling mainly Exynos devices. Workarounds are in many situations are challenging,

I have the exact same phone and using the same network as garyHal, unlocked 988U1/OYM/ATT.
I got my bootloader unlocked and decided to apply the ATT firmware (
G988U1UES1BTJ2). My CSC was already ATT so I didn't perform the csc install step.
After setting the phone up as new, it still seems like its running the unlocked mode. I don't see any kind of branding or extra ATT stuff that may have been downloaded. How do I verify that I have the right firmware and CSC set to ATT?
Thank you.

How did you manage to unlock your bootloader since US Snapdragon variants are locked down pretty tight? I don't think the firmware is dedicated to ATT, it's Multi CSC, designed to function with a number of US Carriers. You should be delighted you're not suffering with ATT bloatware! To check the Active CSC go to About Phone, Settings, Software Information, Service Provider SW ver. On the bottom string the first three letters are the Active CSC on your device. You can review this article for additional information on Firmware and CSC's.

If I am reading it correctly, this is what I am seeing:
ATT/ATT/XAA
I am happy that I don't have the ATT bloatware but I also feel that ATT is locking me out of some of their features because I don't have a "branded" phone, such as wifi call or visual voicemail. Am I misunderstanding your post from above, #6, that flashing ATT firmware would give me the carrier features?
Additionally, does the firmware determine what frequency bands I am using and if I am taking full advantage of ATT's offerings?

Flashing ATT Dedicated Firmware would give you the best chance for additional call features ASSUMING your Ulocked Device is capable of incorporating those features. It should do the trick since the hardware is identical to an ATT device. I would head to an ATT Store to get a definitive answer. Samsung has made it more and more challenging to mix and match branded and unlocked devices with CSC or Firmware modifications. In many cases you won't know until you try. Users want their smartphones to be smart, to work perfectly in every situation but the major carriers use proprietary tools to hold clients hostage.

Hi. I have the AT&T LTE version of the tab s4, SM-T837A. I read that the android 10, One UI 2.1 update for my device went live a month ago, but I'm not receiving any updates. I'm on android 9, One UI 1.1. It says I'm up to date. Any ideas how I can get this update? Does anyone know a safe place I can download it from and do it manually? Sammobile doesn't seem to have it... At least, I can't find it.
If it matters, I don't have a SIM card currently installed on the tablet.
Thanks for your help.
-Dave
because your info is wrong. only the samsung stock versions got the update. all carriers are lagging behind as usual. still waiting for my Tmobile variant also. you can look on sammobile.com and browse the firmware database to confirm what i'm talking about. T837A didn't get the update yet. it;s still on 9
Yes I have the same question. I found only the wifi model is updated to Android 10. Has anyone on a carrier device flashed the wifi version?

Not only wifi version & other variants, except USA carries (verizon,t-mobile etc)
https://www.sammobile.com/samsung/galaxy-tab-s4/firmware/#SM-T830
No you can't, if the device is locked to the carrier...you have to wait update from your carrier ,if it gives the upgrade of course
Att issued the update a few weeks ago, and a smaller update hit my T837a today. It contains September security update and a new radio firmware. link to imgbb if the attachment doesn't work as I'm getting an NGINX error. I been here since 2007 never seen such before...
https://ibb.co/M6Hnkvv
Still won't update
I have the AT&T version of the Tab S4 and it still shows I'm up to date, yet I'm still on the January 1, 2020 security patch does anyone know what to do?
I am in the same boat. AT&T Tab S4 will not update. Is there any way to manually flash? I don't see the update available to download
Complain to att. I pissed and moaned to online live chat support after the international version got it's update. Complained every couple of weeks until finally they asked for my imei, then a few weeks later I checked for updates and it did the 10 update.
I think this has been asked before in a different way in this section but no real response yet. I did some research in the other Samsung device forums and see that often it is possible to remove branding or switch carriers adjusting device ID and bootloader etc. But no idea how to do it for the Tab S4.
I'm sick of waiting for slow updates through T-Mobile (or any carrier) and would like to fully unlock it's potential with Android 10 rather sooner than later. I bought this device second hand network unlocked.
Any short or long answer to these questions? Can it be done? If so where to start?
Am looking to do so, with the t835 you will have full calling functionality,,,

The short answer is no.
I've tried that after I found my T837V can be successfully loaded with T837R4/T837T/... firmware. I thought maybe I could flash stock firmware of other versions. But if you do that with any firmware other than T837*, you will get "secure check fail pit" error. So sadly no.

Thanks for the response! So it does mean you can freely flash T837 versions which could mean I can just wait for the first version that comes out with android 10. Any first release should work. Right?
Turkey version has it:

T837 is Turkey version and I've tried it. It can't be loaded, maybe it need to be T837x which are all US variants.
As for Android 10 update, I think this will work. I'm waiting for the first one who gives the OneUI 2.1 update. So far the Verizon version(T837V) seems to have the most active firmware updates.
In the USA, SM-T837 ARE carrier tablets.
There are the SM-T837A, V, and T; ATT, Verizon, T-Mobile. TheSe are locked to the Carrier. If you have them unlock it, OTA upgrades are over. If you know how to hack the firmware, you can write over the carrier version. The best way to go is probably custom ROM AND ROOTING. But in other nations, it will probably work to write a different Samsung ROM. The SM-T835 HAS no US version, so you can probably write any tab s4 Factory ROM to it.
The USA HAS so many cellular devices, the rules are strict. And, the carriers sell the devices pretty cheap. So, they want them to stay with their service.
T-mobile update for android 10 finally out just got it
