N960F/DS Firmware wrongly detected

So I bought Note 9 in Indonesia with XID firmware, and I tried to change it to Australian XSA firmware so I can use Australian Samsung Pay. I was thinking the process should be easy since Indonesian and Australian Note 9 has the same version (F/DS, Exynos, Dual Sim Hybrid), but turns out its not. When I flashed it with XSA firmware the phone somehow detect the Switzerland AUT firmware. I re-checked the tar file, re downloaded from different website, tried to flash the Switzerland AUT firmware too, tried to flash with Odin and Odin 3B, and the result is still the same.
Is this a common problem? I just want to be able to use Samsung Pay on my Note 9.
These are the download source that I get the firmware from

Home CSC can't modified but you can get some helpful flashing guidence here. Doing so may affect updates.
Change CSC from LUX to DBT
Can I change my CSC from LUX to DBT by flashing the DBT firmware (minus the HOME_CSC, so i keep my data) ? I've just ordered credits from Sammkey but I'm wondering what that is even needed if a flash via Odin will also do the trick. I want to...

I have an ATL device (Vodafone Spain). Apart from the one Vodafone bloatware app that I uninstall via adb, I can use my Magenta Austria SIM just fine. Everything works as intended and I assume this is due to the OXM firmware. So if you don't miss any features, I personally wouldn't bother changing the CSC
If XEH and DBT share the same multi OXM firmware, their firmware is exactly the same. Meaning flashing the DBT firmware will do nothing as it is the same one that XEH uses. The CSC will only change by that method, if you flash a firmware that doesn't have your current CSC included

Question S21 Ultra_Not receiving Firmware Update.

Download right firmware and update on your own by odin.

Question Can I flash a US-based firmware on my s21 ultra while in Kenya(East Africa) SM-G998U? NB: everything else is fine just not receiving updates.

I have a recently purchased galaxy s21 ultra 5G SM-G998U and Im currently stuck on Sept 2022 patch with A12. CSC is XAA/XAA/XAA/ATT. I'm from Kenya and since this is a US-based model how do I go about accessing the updates, do I flash the firmware to the one in my region or the one in the US
Should be fine, as long as the CSC you want to use isn't included in the firmware you're flashing. You must flash the firmware that corresponds to your model number - meaning you can't flash G998B, G998W, or G998N firmware.
You'll need to use the CSC.tar, not HOME_CSC.tar, because you'll need a factory reset.
So I use a SM-G998U or U1 firmware?

Question s21 Ultra SM-G998U I need Change rom To SM-G998U1

Hi Ihave s21 Ultra Version SM-G998U I need To Change SM-G998U1 I Can Change without Risk Loss File Modem What Deferent Between SM-G998U VS SM-G998U1 And I can Received Update Automated In still With rom SM-G998U
You cannot flash your device with firmware meant for another model; this will likely result in your device becoming inoperable.
Why are you trying to do this?
The difference between the two is the G998U is the branded US carrier version (specific to Verizon/ATT/TMobile/etc) while the G998U1 is the unbranded, unlocked version that can be used on any US carrier.
If you're trying to unlock your bootloader, this won't help you.
