[HELP] NOTE 9, region not changed after flashing new ROM

Hi all,
I got Note 9 (N960F) 3 months ago from UAE. First thing I did was installing the UK (BTU) software in it as I'm in the UK.
Even though I'm currently on N960FXXS2ARJ4 build number [UK software] as it's available at SamMobile website
My Samsung Pay is still configured to UAE. And when I click on About Phone on the settings below the IMEI numbers, there is a United Arab Emirates section showing some TRA ID number.
Could you please help?
You need to change csc using combination file before flash the firmware u want. Got many thread about that here. Try search it on how to change csc.

Hello, I live in Korea.
The phone you use is Galaxy samsung galaxyS10 5G(SM-G977N)
But there's a problem.
I'd like to change the CSC.
The CSC currently in use is LUC.

However, the firmware of the KOO model was put in AP,BL,CP,CSC,USERDATA and it does not change.
Is there any way?
Please give me a good answer.
Hi, I now have the same SM-G977N phone which is a single SIM Exynos 9820 variant and therefore identical to the UK SM-G977B and would like to do the same.
Did you have any success doing the change?

-If the following doesnt work, any advice would be appreciated

This is what my watch currently has:
Galaxy Watch3(0FF2)

I would like Samsung Pay and Samsung Health to work in Singapore.
I read this guide & watched this video on the methodology to update firmware and change CSC code.
Features not made available
I'm from Canada, just found out that some features won't be made available to me. So I will not be paying $600 dollars for something that has it's capabilities restricted. I suspect this is beyond Samsung's control, can anyone confirm this...

Change CSC AUT (EUY) to XEF (EUX) possible?

Hi everyone,
I recently bought a Galaxy S20 FE 4G (SM-G780G) in Switzerland. As I am living in France, I inserted my french SIM card, but the phone is still displaying AUT / AUT, AUT / EUY / AUT.
The CSC is AUT (included in EUY group), but I would like to change CSC to XEF (included in EUX group).
It is not really clear for me if this is possible (with Samkey) as the two CSC's are not in the same group. The phone should of course still work 100% after the change and warranty should stay valid.
Thanks in advance for your help.
Yeah you can do that.
Android 12 should roll out soon in our region.. I'm from Germany and use Malaysian firmware, when I flashed I did so without selecting any csc in Odin. And it automatically installed the one I needed I think.
But it will factory reset your phone.
I also installed XME to get Android 12 first. I noticed a worse overall performance though. Are Android 12 ROM running significantly cooler than Android 11 since thermal throttling seems to be an issue to every S20 FE user..? Any CSC that might perform better in this area since some CSCs have regional difference like SER from Russia comes without Bixby?

Click to expand...
Click to collapse
before you pay out money (I've heard that Samkey told one user our device wasn't supported) maybe the method outlined in this thread is worth a try, but using the pit file from XEF
How to change CSC back to original if you are not able to
So i have a S20Fe exynos and me being impatient installed oneui4 SER version on device thinking that will see whatever happens. I am also developer of Clean OS rom for s20fe so i tried using my csc feature script and it worked flawlessly in SER...
forum.xda-developers.com
if it doesn't work fully then the same method should be able to return it to AUT if needed.
curious how it works out if you do try it.
Do you guys know what countries uses EUY and EUX?
I've got a new phone and i like to use AUT ROMs but so far all we have are EUY and EUX, not AUT
