Hi mate
For what i know you can only change the CSC to those CSC's available in the current ROM installed in your phone , An U variant is the snapdragon version for USA (?) it will not have a european CSC available .. and you cant flash an european rom either ( exynos).
So no , no luck to change to a european CSC with the U variant , sorry

Call drop problem
Hey guys, does any of you here in this thread knows how to fix the call drop problem on sgs3? Just bought my sgs3 two weeks ago and I can hardly receive or make a call,often in drops. I can't make calls. As I have read on this forum, some says it can be fixed through modem firmware change,but I have already installed five different modem firmwares and nothing happens. Most of the time I can't send text messages and neither make a call because of the modem from a different region.
Just hoping someone could help me with my problem. Btw, I'm on Sun Cellular carrier.
Any help will be much appreciated. Thank you so much!

Change CSC

Hi,
I recently bought a Galaxy S9+ from Dubai and my CSC is XSG.
I'm looking to change the CSC to ZTO once I'm living in Brazil.
I've read many threads here but I couldn't get a conclusive answer, is it possible to change the CSC on Galaxy S9?
Thanks.

You should have exynos so yes.
Just flash the exynos firmware you want which will give you the desired csc.
Or as an alternative flash a rom which allows you to pick the csc during install

Flashing stock firmware in odin will not trip knox.
Go to sammobile.com and put in your model number and all the available firmwares will pop out, find one from Brazil.

You'll be stuck on XSG and will get OTA updates for that.
ZTO is no longer a valid CSC for Exynos models, since in Latin America, Samsung decided to launch the 'SM-G9650' Snapdragon 845 model instead.
like exchanging csc galaxy s9 exynos. Dude I'm having the same problem here my G965f Singapore XSP I live in Brazil I can not get the right carrier version just OXM _XSP.

If you flash the CSC then yes of course it will change lol.
Then you will get OTAs for that particular CSC.
Just make sure you dont try flashing firmware for a snapdragon if you have exynos or vice versa

Hi everyone i have a question. I am from Bangladesh. I am using galaxy s9(SM-G960F). I SEARCHED in sam mobile for the latest firmware for my region which is BNG and found only 2 firmware both of which are from March 18. So i flashed the BRF8 june patch version from German DBT REGION using odin. Still my active csc remains BNG. Now my question is will i recieve future ota updates as usual? If not what should be my next course of action? Thanks in advance.
Will this work for snapdragon variants?

Any idea about this
hello if you want to change csc you should flash it by odin and then formate the phone to change it , if only flash csc file it will not change
To change the csc do you need to only flash csc or do you need to flash everything?
Since the 9650 and 965u are practically the same phone just one was shipped to Latin America while other one is international could I flash the 965u on my 9650 to enable Samsung pay / change csc?

Hey,
I have a 965N - meaning s9+ from Korea. I got it there, but know I want to flash a German / European version but CSC needs to be changed because of partition size.
Do I just need to change CSC and partition size will change ?

CSC changeable yet?

Hi,
I have the 965F dual sim it has taiwan csc.
I`m now in Australia and want to use on telstra.
I loaded telstra firmware onto device from odin and did the default csc.
factory reset with telstra sim in and still it`s in taiwan.
How can I change this?
I guess not. Hopefully some one can work it out soon.
nope it wont. even in the future.
what makes you think that?
Have you tried #272*imei#* then choose a csc code?
yeah it doesn't seem to work on dual sim
I tried playing around like *imei 1*imei 2#* etc
nothing seems to work.
waa hoping someone with elite skillz could work out how to make an app on PC force change csc without rooting.
I have a SM-G9650 bought in Paraguay and no matter how many times I installed the ZTO firmware my csc continues showing as UPO..
I followed a lot of methods and no one worked..
The worst thing is that a lot of people did what I did and had success.

Changing CSC is not possible on your SM-G9650 without root.
same for the 965fds?

Not true.
I read that others members with the mobile bought in Paraguay had success in changing the CSC after installing a ZTO firmware.
I also changed mine once, when I installed a ZTR firmware, but then I updated my firmware and it came back to UPO csc.
I have a G965F/DS and tried all kinds of method including combination ROMs and *#272*imei#, none worked. I have XID CSC trying to change to XSP, or XSA or any that has VoLTE and Samsung pay. I don't have a sim card from those countries.

Change region for samsung pay.

Hi!
I got a Samsung S21, model nr SMG991B/DS. Which seems like the international version. But my software version has DTM in it (according to samsung support, this is the german version).
So because I have the german version I can't use Samsung pay properly its looked to the german region. So I would like to flash it so it changes to Nordics region.
Is this possible if so how or is there any other way to change the region for samsung pay?
The phone is not locked to a carrier.

Hi mate
Yes there are ways , check my post here
For Samsung Pay to work the phone CSC and the Samsung pay account must be from the same country , in your case if phone region (CSC) if from Germany but your Samsung Pay account if from somewhere else it will not work ...
So first thing you should do is check your phone CSC go to Settings /About phone / Service Information .. there check under service provider software , you will see the CSC information in your case in this format XXX/ ZZZ,ZZZ/ YYY
XXX will be you active CSC, this is the one you need to change to the right country
ZZZ are sim related, with dual sim you got 2 sets
YYY can't be changed is the region where to the phone was manufactured for , not important , it has no effect
Hi!
UNder service provider software i get DTM/DTM,DTM/EUX/DTM. So I'm guessing thats germany.

Hi
DTM is Dutch T-Mobile (Germany) .
You need it to change to your Country / Samsung Pay account to make it work
Is not that much the rom but the CSC , you may need to flash a new rom if your desire CSC is not installed in your current rom...
How do I find out if the CSC is in my current rom? I need the swedish CSC.

You dont have to change the CSC, just flash an unbranded EUX rom.
DTM is, where the phone was activated, if i remember it right.
If i flash a orignal EUX Firmware.

I bought my phone in Vietnam, but live in Israel and preferred to have my local CSC. I don't know if I could use VoLTE or WiFi Calling without changing it.
And yes OEM Unlock is an option for me under Developer Options.
Since different people are asking different questions, let me post what I know and can help you.
1. You are trying to change CSC from A to B which belongs to same model, can be easily done using SamFW tool or you can also try Samsung shell exploit from S22 forums.
2. U to U1 can be cross flashed using patched odin, which will change csc too.
3. If you are trying to do cross flashing means your model no doesn't match the model no of CSC you want to have like XAA to INS then sorry it's not possible.
