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.

I have an unlocked US TMO S20 5G that I would like to reset and use in Spain with my Spanish SIM card, but not with all the US TMO firmware etc.
Can I flash a Spanish unbranded/unlocked firmware or should I flash the unbranded US firmware?
Assuming I can flash the Spanish firmware, what are the procedures?
Thanks!
Spanish Firmware isn't compatible with Snapdragon devices, it's designed to operate alongside Exynos Chipsets. You may want to flash the US Unbranded Firmware SM-G981U1 and go from there.
I have already wiped everything on my galaxy a505w carrier: XAC Canada for Corvus. But I didn't try to flash when I knew that my phone it isn't supported. Can you tell me any sort of custom ROM for my specs above. ROM's name and version with link would be appreciated!!! Thanks in advance!!!
I bought the fold 3 off ebay(yes I know)it has the CSC number ending in CVEB
I can't find out anything about the CSC code. My model number is SM-F926B/DS
Any help would be great.
Thanks
Looking on sammobile it means H3G

So I think that's the 3 net work.
Would it be better for update to stay on the rom or flash a BTU rom?
There is no such CSC as BTU anymore, at least on a z fold 3, what's your service provider software ?

BTU has gone!
My phone has no provider.
But the ROM is B3G which is three.
So it must of been on three at some point.
It probably is running three branded software, but that will just be your original CSC code. If you wanted to change it you can, with free software from samfirm but the equivalent to btu now, is eux, Samsung have changed the way updates happen. UK the no longer has its own CSC unbranded code, we fall under eux, so Samsung can release faster updates all at once
By 3 branded I mean the ROM is customised for the 3 network, apps added etc. mines on o2, but that's an multi CSC ROM, oxm which means it has multiple CSC, including eux etc, but eux doesn't come with network customisations and is now the European unbranded
