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?
Hi,
I'll be getting a Canadian S9 soon but i have no need for the device and i'll be sending it to my sister in the states (she is on AT&T). I want to know if i'm OK just flashing the latest version of the US firmware to the Canadian device? and what is the CSC of the unlocked version of AT&T in the states? Will she be able to update as usual after that and will Samsung pay work?
Thank you very much in advance.
Hey I need some help, I have a Galaxy S9 AT&T version but I don't live in the United States. The phone works just fine but I don't receive any updates even through smart switch. I'd like to know how to install the U1 version which is Samsung's carrier free version to my phone. Can anyone tell me the steps and which U1 version should I install?
Hello and awesome Easter everyone!
I live in Norway and used to have an Asus ROG Phone II until last week, I swapped it with a Note 10+ 5g Korean edition.
The phone is working nice and it is A LOT BETTER than the ROG, that phone is a powerhouse, but the software, not so much...
With this phone I have a few problems:
•Lots of stuff in Korean
•Cannot save home numbers with country code or the contact name won't show when anyone calls or text.
•Norwegian language not fully supported.
Everything else works flawlessly and I love the phone so I wonder if there is anyway I can fix this, even if I have to root, it's not a problem. Been thinking if I could flash firmware from the 975f as it 8s the same soc.
Will be very appreciated if someone could help me with this!
Have no problems with flashing and rooting, just don't do it for a long time. Thanks in advance!
Is it carrier branded? If so, try flashing the KOO csc firmware, that may help with some of your issues.
You can't flash the N975F firmware, as it's not meant for the 5G variant.
The N976B model is the 5G variant, but it also cannot be flashed to the N976N.
I have KOO installed now and i have all the "problems". I know the 976b have snapdragon 5g modem and i have exynos. Oh well gonna have to live with it! Thanks for the help!
SM-N976B is Exynos.
Edit: just curious, have you been able to get it working with 5G?
my sim is not 5g nor we have 5g in my area yet unfortunately

You can use PD MDM package blocker to kill the bloatware at boot up. Useful to have.
Thanks it's work =)) not exactly what i wanted to but it's fine . I disabled all the korean blootware :good:
If you open a individual app in PD, in the upper left corner is a box. If you check it the PD MDM widget will toggle any checked app on or off.
If will clear data in apks better than doing it in Settings can; presumably PD leaves no nulls.
If you ever get the flashing screen warning thing *oh no* you need to deactivate PD MDM as system administrator.
PD runs in safe mode! It's been very stable and haven't seen this happen in years.

flash koo firmwere download through sammobile
I have bought SM-N976N but the seller had flashed SM-N975F firmware in it. I have now flashed it with KOO version of SM-N976N but my problem is that the phone is not recognizing sims or carrier in it (not even 3G or 4G) Ping test is always failing. BTW I am from Pakistan.
So my question is , Can I flash OXM version of SM-N976B cz my region will be covered in it. Because samsung has not launched a PAK version of firmware of SM-N976N.
Please help how will I be able to get my sims working in Pakistan with or without root? Please help anyone.
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.
