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.

Anyone found a fix for Samsung pay?
I imported a Note 10+ from Canada (N975W) it was from Rogers, but they sell all their devices unlocked anyway, I'm here in the UK & using a EE sim card, everything works perfect apart from Samsung Pay.
So my question is, am I on the best possible firmware I can be?, In the UK we have the Exynos Note 10+ so it's not possible for me to flash UK firmware right?
Also my CSC is XAC/XAC/XAC/RWC
XAC is unlocked, RWC is Rogers, so is it just displaying that the device was originally on Rogers & is now on unlocked?
Any help / information is appreciated.
So RWC you can't change and it doesn't affect software updates. First two makes sense what updates and where you gonna recieve | Country / Region / Operator. Unlocked or not, it doesn't give you faster updates. XAC is sim free version code for Canada, I believe. And don't flash Exynos firmware on SD.

So in summary XAC is the best firmware I can be on because it's SIM free which means no carrier bloat, RWC is meaningless (just signifies the original firmware I'm guessing?), & I can't get but also don't need, UK firmware?
Yes you are right. And yes you don't need UK firmware.

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.
Can i flash us firmware or canada fw on Japanese g975j galaxy s10 plus with snapdragon soc,or can i at least flash some normal fw to debrand the phone to make it more normal,its from some AU carier and there is a lot of bloatware on it.
I want to flash a different region firmware (in this case korean) on my device, an s20 plus unlocked (with csc xaa). The reason is that I wish to unlock 5g band n78 that the us firmware of my device does not support. I know that I cannot flash a european exynos firmware, but the korean model SM g986n has the same soc (snapdragon 865) and is single sim. In another thread (https://forum.xda-developers.com/t/flashing-from-sm-g986n-to-sm-g986u1.4072579/) the owner of a Korean s20 plus attempted to do the opposite and supposedly failed, because its korean model lacked mmwave 5g antennas that the american model supports (albeit probably calibration on the chipset is different). So thit is my question: is the reverse operation possible? Do I risk to brick the phone because of hardware limitations? Do I have to unlock the bootloader to flash the korean firmware or samsung frp tool could do the trick? I am open to suggestions here, thank you in advance.
