I'm trying to get the USA version of Samung Pay working on my SM-G9600 (International Unlocked Snapdragon S9). Unfortunately, my active CSC is currently set to TTT (Trinidad/Tobago... not sure how, I flashed a CHO firmware, haha), so even when I have my Samsung Account and AT&T SIM card inserted, opening S-Pay just gives me an error, "Unable to connect to Samsung Pay temporarily. Try again later."
To remedy this, I think my best option would be to flash a new CSC from a different region? However, I don't really understand how Samsung's CSC system works; I've tried researching it, but I haven't found anywhere that really explains in detail what CSC actually does, single-CSC vs multi-CSC, etc... Can anyone give me a summary of all the major parts? Or at least point me towards a good resource to learn about it?
However, I have more practical, direct questions:
Could I flash my G9600 with just the CSC (or better, HOME_CSC) of a USA Snapdragon variant, like the U1? Or would that break things, since it's a different model number? Would that be likely to get me a working Samsung Pay?
I guess I should flash the CSC (or better, HOME_CSC) of a different region that also carries the G9600? Of the regions that carry the G9600 (China/Latin America), I believe the only countries that support Samsung Pay are Brazil, Mexico, and Puerto Rico (and Hong Kong, but only with Hong Kong banks? I think.) If using a CSC from the US is a bad idea, which of these would be best? I'm guessing Puerto Rico, since it's most closely related to the USA, but the only PCT firmware on Updato currently has the v1 bootloader, but I'm already on the v2 bootloader (2ARE6), so I don't think I can use it.
I would guess that the next best option would be Mexico, since it's pretty close to the USA, and I see a firmware with the v2 bootloader for it on Updato. However, I'm not familiar with that region code. Is MXO a specific carrier in Mexico? Or is it the carrier unlocked firmware, like U1 is in the US?
MXO is unbranded bro and working samsung pay.
I wanted flash a specific carrier csc but I couldn't set TCE always appers CHC.

Did you end up flashing the MXO ROM? If you did, do you still have dual SIM capability after that? Thanks!

Yes! Dual SIM is not affected by which SM-G9600 firmware you flash. The thing to be wary about would be if you tried to flash a different model's firmware to it (e.g: G960U), since there is no Dual SIM among the U models. Although if I had to guess, the Dual SIM settings would probably still work fine (assuming the U firmware didn't brick it otherwise).
Have you found a fix for this problem, are you able to use samsung pay here in US?
Did you change the csc only or flash the whole frameware?
Thank you in advance.
I'm also wondering about flashing just the CSC on a dual SIM device. I have a Note 9 dual SIM that will not get Volte, so I was thinking about flashing the U1 CSC to see if it would fix it. Does anyone have any advice?
You guys are so good at this compared to me. I felt like a noob ?.
I posted a question a few days back but not getting a meaningful answer. The goal is to do minimal changes but get Samsung Pay working.

I live in Canada and have a N975W and want to flash the star wars U1 firmware, but before I do I wanna know what happens when you put a Canadian Carrier sim in?!? Will the U1 CSC have Canadian Carrier info preset? Will I have to manually modify to get things like MMS to work? Or does the U1 firmware have Canadian stuff preloaded that gets triggered with the Sim card?
Thanks
Nobody?
Exynos

The American CSC does not contain information for Canadian carriers. After you flash the American U1 firmware, flash the Canadian CSC. There is only one CSC for Canada, and it contains information for all the Canadian carriers (Bell, Rogers, Telus, etc.). After flashing the Canadian CSC, when you insert a SIM from a Canadian carrier it applies the settings for your carrier's VoLTE, wi-fi calling, APN, etc.
If you flash Canadian CSC after flashing full U1 firmware will it not effect the U1 firmware? The CSC file is so large I'm wondering how it will effect the U1 firmware. Anyone do this yet? Do I need to use modified Odin?
Have you done this? Does flashing a different CSC effect the firmware?
---------- Post added at 11:58 AM ---------- Previous post was at 11:57 AM ----------
I would appreciate any input from someone who has tried this please. I really want to flash the star wars Android 10 for U1 on my 975W but am afraid that CSC will be different and not sure If flashing CSC from a different firmware will work as the file is so big.
if it doesnt work, you just flash back to stock firmware and csc.
just make sure its for the same processor.
OK, so, I flashed first Star Wars Android 9 version of U1 firmware to test and it works perfectly. Booted up with Canadian carrier sim and it loaded all APN settings. Everything works perfectly.
Flashed Android 10 version of Star Wars U1 firmware and its all good.
So you can load U1 firmware on N975W unlocked version. Same hardware and works in both countries. Do not even need Canadian CSC.
Do not load the HOME CSC file. It will wipe everything but its worth it. Firmware is solid and beautiful.
By flashing unlocked firmware, did you get rid of any carrier bloatware?
Can I ask you guys an info? I own N975u1, on first boot It haven't Greek language and I choose it later at setting. Does N975w on first boot has Greek language? So I install N975w firmware to solve my problem?(some settings remains in English).
975W is Canadian model and i have it on my note 10+ with carrier esk or eastlink if you wish to know what carrier esk stands for. If you are trying to get your phone to show Greek language I do not believe the 975w firmware would be a good choice. It lets you select which country you are from when you start up a freshly formatted phone but I have never selected any language other than Canada which is English. Just thought I would let you know that my model is also a Snapdragon chipset and I don't know if you can Flash another firmware unless you unlock Bootloader and I do not know if that is possible currently on a Snapdragon chipset Note 10.

The only phones with an unlockable bootloader are the N9750 (chineese variant) and Exynos models.
Can you please be more specific with what you are looking for within regards to firmware. Other then the information/answers posted in the first page of this thread I saw this thread, but depending on what your looking for specifically the post may not be of any help.
Also be aware that if you want to retain full compatibility with Virgin then you shouldn't go messing around with the firmware. Flashing other firmware (especially for US models) can result in things not working the way they would normally.

Only firmware for OEM UNLOCK switch in developer menu is exynos models. I found other sites on the net stating SM-N975W Snapdragon can be bootloader unlocked but i tried them all and none worked. DO NOT flash exynos firmware on Snapdragon model as you may ruin your phone or void warranty. Luckily mine still shows official and knox counter didn't get tripped. Sorry, wish I had better news 4 ya.

Hello Everyone,
I have the SM-G985F/DS in Canada. The current CSC is XSP/XSP,XSP/XSP.
This phone is the international variant. Can someone please guide me on how I can change the CSC? I am a total noob. I would like Samsung Pay/ VoLTE to work. Preferably Fido CSC or Unlocked Canada, some bands aren't working properly.
If this isn't possible will I get updates for my phone?
This has been a big headache.
The phone is Exynos and I'm in a Snapdragon country.
Thanks

Since you're using an Exynos phone in a country where they officially sell the Snapdragon variant, you won't be able to flash the Canadian CSCs since they're only available for the Canadian variant.
VoLTE should work after you insert your SIM and reboot the phone, I've seen multiple reports of VoLTE no longer requiring the correct CSC to function.
Messing with band support is almost impossible on Exynos variants and I believe Samsung Pay requires the correct CSC to work so you're out of luck there.
All this aside, you will still get OTA updates based on when they're released for the XSP CSC.
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

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.

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.

I misunderstanding
What a trick bro
It's a link for firmware updates
I need to know which one compatible with my note
And after flash will still unlocked?
Hey guys, so my question is how can I upgrade my Note 10 plus to Android 10, I have the SM-N975U model with ATT, i live outside the US so the person who sold me the phone unlocked it, the thing is that I was checking the original firmware for this model in Sammobile but alm versions are from different carriers (Verizon, Xfinity, etc) I didn't find the one for ATT. Does this make a difference? which firmware should I download?
Just follow this thread. You can use T-Mobile or Verizon firmware. All the same but Just use Home CSC for no data loss. You will not find the AT&T firmware using Frija or Sammobile (or anywhere unless someone extracts it & posts).
Check this thread out.

Hi mate. I don't know if it's gonna help, but I live in UK and I had 975U too which was on Android 9.
System didn't allowed me to update it, probably cause it was on AT&T so I followed a tutorial on yt and updated it to 975U1 Android 10.
EDIT:
N975U and N975U1 Firmware Links Here
For those who aren't already aware, N975U is the model number of all of the US carrier versions of the Note 10+. The N975U1 is the model number of the same device, but sold by Samsung SIM unlocked and with no carrier bloatware. Firmware is 100%...
