So I just bought used Galaxy S20 Ultra but the firmware is stuck at One UI 2.1 with latest update in June 1, 2020. When I want to update manually it say my CSC code is XAA/XAA/VZW. I googled and found that's Verizon unlocked device. The problem is the only available firmware in https://samfw.com/firmware/SM-G988U is VZW and XAS. If I flashed using VZW firmware does my device going to get carrier locked or should I choose using XAS? I live in Asian so obviously I don't want VZW locked.
bump. can i bump this post?

Hi All,
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With that said, I noticed that the software is outdated and the security patch level is on February 1,2020.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.

All of them for that model S20, you just need to match the model, any region will work fine
Hi,
Are you sure I can flash Verizon firmware into AT&T device? CSC may to match?

Hello,
I am new to the unlocking stuff.
I just bought a used ATT Note10+ 5G in Malaysia, model SM-N976U
However the security patch was stuck in May 2020. It could not be updated over the internet or Smart Switch PC.
It says it is the latest s/w (the latest should be July 2020)
I checked Sammobile and discovered 2 firmware updates : USA(TMK) and USA (T-mobile)(TMB)
(tried to include sammobile link here but was disallowed due to new user status)
Which firmware is suitable for my phone?
Is there a way to unlock ATT and receive the normal monthly security update over the internet automatically?
(i saw Odin in youtube and have basic idea how to flash it)
Appreciate any advice. Thank you

A thread already exists with the answers to your questions.
https://forum.xda-developers.com/galaxy-note-10+/how-to/att-note-10-5g-n976u-firmware-files-t4059721
No unbranded firmware version exists as of yet.. so you will have to flash a carrier specific firmware.

Thank for for the link provided.
Based on the link information, i can download the 4 base files from sammobile (either TMK or TMB) and add USERDATA ATT N976USQS3BTF4 to flash it.
Is that correct?
I could find USERDATA ATT N976USQS3BTF4 in easy-firmware website with a purchase fee.
(editied: My phone Active CSC Code is XAA, CSC Country is USA)

Hi SCitta,
Fellow Malaysian having the same problem as you. But my problem now is that I have Odin and the latest firmware (XAA) but Odin is showing failed to establish connection. How did you do it with yours?
Am using the AT&T version of the Note 10+.

Never experienced the failed connection before.
Have you installed the SAMSUNG-drivers ? The Samsung Smart Switch PC installation might help to fix the drivers.

Just want to share my experience in this. Bought an ATT N976U from the US and using in Malaysia. Phone came with XAA/XAA/ATT and never received OTA updates.
Downloaded Google phone app and changed CSC to TMB/TMB/ATT using *#*#27262826#*#*
Voila. Received the OTA updates one by one since May2020. Am now on N976USQU5EUC2.
Volte is also working on Celcom.
Did not have to flash firmware. Data not wiped. Everything seemed to be working normal apart from "Tips and Help" in settings crashes every time I click it. Also phone boots with T-Mobile logo now.
So please forgive me if this has been answered before, but I have not been able to zero in on an answer to my problem by searching the forums.
I recently bought an international SM-N975F/DS that I bought through a reseller in Canada. The home region is Vietnam. I am using SIMs from Telus and Roger's. This is my first international version of a phone that I have owned.
I would like to upgrade to the latest firmware but the phone is telling me that I am up to date. I'm happy to wait for the the regional update, but i am not sure it will be triggered while I use the phone in Canada.
I am open to flashing another version of the firmware in order to get the update, but I am confused as to what version to use. Since the dual sim version of the phone was never released in Canada, I'm not sure what version of the firmware I should download.
Also, if I am able to switch the region to one where Samsung Pay will work in Canada, I would love to do that. I'm not sure which country version will work here.
And my final question.... if I do flash a different region will it update manually or will I have to download and flash each new software update and security patch?
Thanks for any help you can offer.
I believe you need to figure out which sm-n975F receives the fastest updates and then flash to that specific region .
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.
G986U and G986U1 Firmware Links and Flashing Discussion Here
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%...

Hello everyone
I bought an S22 with model number S901U (carrier locked T-mobile) from overseas in Dubai that I received unlocled in someway but was stuck on October 2022 security patch and android 12. It says it is up to date and refuses to find newer versions (no updates detected or pushed).
I manually updated the software to the february security patch and android 13 using sam mobile site and odin.
(I used the CSC that matched the device that was TMB/XAA)
After the update, the software version became ASR/XAA,XAA/XAA.
So the first question, what does this ASR stand for, I couldn't find it in any CSC abbreviations.
Secondly, the TMB is not shown, so does this mean that I will start receiving OTA updates directly from samsung?
(From what I understood, the phone is not receiving updates because it is the carrier locked version that has no connection/relation to the carrier, so will this software version change affect this).
After the update, I didn't detect any faults or problems so far, the device is still carrier unlocked and works fine till now.
Any help in explaining the situation will be much appreciated.
