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,
Are you sure I can flash Verizon firmware into AT&T device? CSC may to match?
Thks
I bought a second hand S20+ that is supposed to be a verizon model. It doesn't have the standard verizon bloat software so I am doubting it is a verizon model and more like and unlocked version. But on the software update it lists a VZW samsung site to see the software change log. How can I determine what version this phone is?

I now have new doubts. My build number is QP1A.190711.020.G986U1UES1BTK1 which doesn't match anything on the verizon website.
And the android 11 update isn't showing up on my phone.
So it appears I have the G986U1 software and not the G986U version which got updated for verizon. Is it as simple as downloading and flashing in odin the G986U vzw firmware?
Hello -
Guys for last few days i have been trying to install Android 11 OneUI 3.0 update to my S20+ 5G phone. Since i did not receive the update, i was trying to flash it. But i couldnt flash that, in fact, I softbricked my phone in trying so. I will try to explain details here, please guide me to identify the correct firmware to flash.
This phone is unbranded and USA variant, which I bought from someone. I don't have the box but it is unlocked and unbranded phone, any SIM works on it. I tried looking for the CSC and AP version, which I found
AP VERSION G986USQU1ATAW
CSC VERSION G986UOYN1ATAW
I could only find one firmware matching this, which was still Android 10. And it had CSC code = TMB on SamFW website. I was confused what my actual CSC is, i tried looking for with the "Phone Info" app and it mentioned the "Active CSC Code: XAA".
So I tried following firmwares from Samfw.com
Samsung Galaxy S20+ 5G SM-G986U - TMB - G986USQS1CTL1
Samsung Galaxy S20+ 5G SM-G986U - TMB - G986USQU1CTKH
Samsung Galaxy S20+ 5G SM-G986U1 - XAA - G986U1UES1CTL5
Samsung Galaxy S20+ 5G SM-G986U - SPR - G986USQS1CTL1
I couldnt flash with any of the above firmware. It mostly stucked while flashing "super.img", i was using Odin 3.14 patched.
After trying this flashing, my phone was softbricked and i was unable to flash any of the firmware but one thing worked (which i dont know why). I flashed AP, BL and CP with Samsung Galaxy S20+ 5G SM-G986U - TMB - G986USQU1ATAW since it's AP version and CSC was matching exactly same to my previous AP & CSC versions. But this firmware's CSC file was not being flashed to my phone, it was always getting stuck on flashing "prism.img", so i flashed CSC file with Samsung Galaxy S20+ 5G SM-G986U1 - XAA - G986U1UES1BTK1 and the phone thankfully restored back to Android 10. But now my software update section says "Your current software version isn't supported. Visit a service center."
And now after flashing, my CSC version is G986U1OYM1BTK1 which was G986UOYN1ATAW earlier. I read somewhere that in the CSC version when you check from *#1234#, the three letters after your phone model is the CSC code. According to this, for my actual firmware it was OYN i think (G986UOYN1ATAW) and now after flashing it is OYM i think (G986U1OYM1BTK1). I don't see any firmware website mentioning any firmware with this CSC code. I am very confused now, do i not have any updated firmware for my phone or i have been trying wrong firmwares.
I am attaching current screenshots below about current state, Please help me understanding how to get the right firmware version to flash. If anyone has same version and has flashed, please enlighten.

To check the original CSC go to Settings, About Phone, Software Information, Service Provider SW ver. On the bottom string the last three letters will be your device’s original CSC Code. Doing a Factory Reset will restore it to the original firmware but be sure to backup your data.
You have a Multi-CSC device. Your best option to receive timely updates is setting the CSC to match your Service Provider. 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 dial, you should see a screen with the list of available CSC codes for your device. Select the CSC for your Service Provider and tap the Install option.
Samsung's Smart Switch platform often times will offer updates before they're available via OTA. Be aware Android 11 One UI 3.0 isn't completely stable, many users are having issues after updating.
So my service Provider SW ver is "XAA/XAA/SPR", which means my CSC code should be SPR. My question is then why this Samsung Galaxy S20+ 5G SM-G986U - SPR - G986USQS1CTL1 did not work? :/ It should have.
Also, why do i see the same AP version and CSC version with this firmware Samsung Galaxy S20+ 5G SM-G986U - TMB - G986USQU1ATAW, whose CSC code looks to be TMB. Its very much confusing.
AP VERSION G986USQU1ATAW
CSC VERSION G986UOYN1ATAW
Plus, this doesn't work in my country i believe. #272*IMEInumber#
So the phone isn't an unbranded device, it's branded by Sprint which is now T-mobile. OTA Updates aren't going to be available unless you're on Sprint/T-Mobile's Network using a Sprint/T-Mobile SIM Card. I'm not sure where you'll find the correct FW for your phone, that's why performing a Factory Reset is going to be the best option to receive OTA's.

Since it's a Sprint Branded device there is no FW change will allow you to receive OTA's. The only option is Smart Switch after you do a Factory Reset back to the original Sprint FW. Curious why you aquired a US S20 for use in Pakistan? The Global Exynos variant would have been appropriate if call features and updates are a priority.

The Original CSC can't be modified, it will remain SPR. This FW is for a US Unbranded device, it won't receive OTA's for a Sprint Branded phone. Since the user is in Pakistan and not on Sprint's Network or using a Sprint SIM the only option is downloading updates via Smart Switch after the original FW is restored by Factory Resetting the device.
Well i acquired it because it had snapdragon and 12GB RAM unlike the global exynos version and its not branded, there's no logo and its totally unlocked. So i didnt have any idea it will have Sprint FW.
SmartSwitch doesnt show any update. And now even my phone says "Your current software version isn't supported. Visit a service center."

I already have tried flashing with this firmware it dint work. But i didn't change CSC before trying, is it changeable?
Since the original CSC is SPR it is a Sprint Branded device even though it may be unlocked. Updates are pushed by Samsung for specific devices based on the device's Original CSC, not the Active CSC. The only way you'll receive updates is via Smart Switch with the phone connected to a PC, Laptop or Tablet after you've installed the Sprint FW.
Not sure how valuable the update will be to you since it's structured for Sprint but either way you might consider holding off on Android 11 OneUl 3.0, it's not yet a stable version. Many of the recent posts here are S20 users who've developed issues after installing the 3.0 update.

Not sure how valuable the update will be to you since it's structured for Sprint but either way you might consider holding off on Android 11 OneUl 3.0, it's not yet a stable version. Many of the recent posts here are S20 users who've developed issues after installing the 3.0 update.

I suggested such a way because the user says xaa for csc. I agree with what you said except that if the SPR software burns, will the SPR not ask for the sim card at startup?

Can't say but typically a SIM isn't required to setup a Galaxy device. The real problem is the user wants updates for a device which is operating outside of it's native region. Many users who opted for the Snapdragon SoC to avoid a Exynos variant are having the same issues. The Sprint CSC is in conflict with his region.
The Active CSC can be changed to function in Pakistan but it can't be updated. I've explained the only method to update the device in his/her region but to what benefit? If a user has a priority for updates and call features the best bet is always acquiring their Service Provider's device. Samsung is the real culprit here by using competing chipsets on the same model numbered devices.

To check the original CSC go to Settings, About Phone, Software Information, Service Provider SW ver. On the bottom string the last three letters will be your device’s original CSC Code. Doing a Factory Reset will restore it to the original firmware but be sure to backup your data.
You have a Multi-CSC device. Your best option to receive timely updates is setting the CSC to match your Service Provider. 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 dial, you should see a screen with the list of available CSC codes for your device. Select the CSC for your Service Provider and tap the Install option.
Samsung's Smart Switch platform often times will offer updates before they're available via OTA. Be aware Android 11 One UI 3.0 isn't completely stable, many users are having issues after updating.

Hello sir I have S20+ 5g Canadian, g986w Snapdragon model, nd I'm frm India I want to change csc of Indian but there is no options for INS/INU , there is only 8,10 csc option how can I change to indian ??? Plssss help TIA... Yeahhh I also downgraded it to android 10 oneui 2.5
Finally upgraded my Samsung Galaxy S20+ Snapdragon SM-G986U to ANDROID 11, ONE UI 3.1
After getting failed in failing many of the ROMs earlier, I tried latest android 11 of 1 June, 2021 build of CSC "XAS" and model "G986U" and flashed only AP, BL & CP file. Didn't flash the CSC file, CSC file was still the older, which worked after last soft-bricked (CSC: SM-G986U1 - XAA - G986U1UES1BTK1)

Hey, I have a similar issue and I live in the same country, I got a unlocked Samsung s20+ 5g snapdragon variant and I have already done factory reset but it doesn't show any updates in the settings it just says "Your current software version isn't supported." and it says software is latest version in smart switch.
My CSC is a bit different than yours: XAA/XAA/WWD
I have attached the smart switch pic, can anyone help me update the phone to the latest version?
Also a question to kas07, was your phone official pta approved or cpid?
Hi Community,
I bought my S20+ 5G in October and since then it has not received any updates, neither security patches nor Android 11. I called AT&T and Samsung both but they kept putting the blame on each other. By searching online I realized this seems like a theme in these kind of issues. The only option I feel I have at this point is to install the upgrade myself. I'm more concerned with Android 11 than security patches. I still got for security patch from June 2020 and One UI 2.1.
With this context can you please help with the below questions:
1. When I try to look up the firmware using Model:SM-G986U and CSC:ATT in Frija or SamMobile nothing comes up. I'm looking for G986USQU1CTKH. Am I missing something?
2. But it does come up with CSC:TMB. Can I install this version on ATT branded phone?
2a. Is the TMB version exactly same as ATT version?
3. Does this process trip the Knox counter?
4. Does this process void the warranty?
5. Are missing software updates covered under manufacturer warranty?

AT&T doesn't allow their firmware to be publicly available for any of their devices. Have you attempted updating your device with Smartswitch? Flashing T-mobile's firmware isn't an option to receive updates on your device. This post has information and answers to your questions.

For those who aren't already aware, G986U is the model number of all of the US carrier versions of the S20+. The G986U1 is the model number of the same device, but sold by Samsung SIM unlocked and with no carrier bloatware. Firmware is 100%...
