Hi there,
Is it possible to change the CSC of my note9 SM-N960F from Australia (XSA) to Singapore (XSP)? I believe both are part of the multi CSC OXM firmware but there's little information on how to go about changing the CSC.
So far I've tried the following 2 methods but unfortunately, I'm still stuck on the XSA CSC.
Method 1:
- Power off the device
- remove the sim tray.
- Go to recovery , HOLD bixby button + Volume up together , and power up
- In recovery , chose factory reset .. This will give a warning and then reset everything
- Choose power off , in the recovery and insert sim tray .. you should do this before booting up as your CSC will be configured when you will start
- Power on the phone , wait and . then chose restart to system now when asked
- wait and after reboot. CSC remains unchanged
Method 2:
*#272*IMEI# to change CSC but I'm getting the "connection problem or invalid MMI code"
any input would be greatly appreciated!
hello
you can try this solution in post 67 : https://forum.xda-developers.com/ga...n960n-n960u-n960u1-n960w-n9600-t3833721/page7

Hi, I have tried the solution in post #67 but my CSC is still XSA. Is it possible to just download the XSP OXM firmware and flash via odin without tripping knox?
at this time i'm unable to make a working N960 CSC file with only one CSC ( noboby is able to signe CSC file ) and as combination file don't work for this device the only solution is to find a working secret code
sorry and regards
I have N960U usa unloacked, on 8.1.
I also have Thai SIM CARD not in use.
There is any way i can upgrade to Pie 9.0 without loosing call recording?
If i get THL CSC on my N960U i think call tecording will work.
Sny way to do this?
METOD TO CHANGE CSC (tested on N960FD) Install this rom https://forum.xda-developers.com/galaxy-note-9/development/rom-galaxy-project-t3911947 choose csc. then you can come back to your rom, I came back because I like a lot of modifications but this rom is also nice. After this operation It should be good. it helped me. I had CSC BTU samsung and I could not change the method, I did not try with the combination rom because I did not want to play like that. I know that some roms have options to choose the csc at installation and I have used it.
I hope I helped
Hi fellow XDA members,
I own a Galaxy Note 5 (SM-N920I) which was bought in Singapore under operator Starhub (STH). I happen to use this phone in India and I later realized the phone supports VoLTE but the firmware didn't so I stuck with using the Jio4GVoice app for a long time now and I'm done with it due to lot of bugs and call drops.
I looked online for solutions and found many that involved root or custom recovery to flash the so-called VoLTE fix. I have read articles that said the Indian firmware supports VoLTE so I So, I tried the following:
Download the Indian firmware and flashed via odin. But it fails with error specified file not found. Did a research and i unchecked the Re-partition and again tried and it fails at flashing system . So I re-flashed the STH firmware to get the phone boot up. I learnt that CSC is responsible for getting the region specific network to work.
Extract CSC from Indian firmware and simply flash it on odin. But, as articles say that I'll have 4 files for each boxes to place in odin I only had one tar (<firmware_HOME_tar.md5). Then I read, extracting the modem.bin file and ziping that to a tar file and flash it via odin will help. I tried that but no luck (should I factory reset it?).
Both the firmwares have a single file and articles say that there will be CSC_<firmware>.tar and CSC_HOME_<firmware>.tar.
I don't know where I'm getting wrong. Is this even possible or i'm simply wasting my time? I use samsung pay and S health extensively so I don't wanna trip knox.
Update:
I read that cache.img is CSC from here. So extracted the cache from Indian firmware and flashed that to my phone that has STH firmware. I used the Phone info app and found baseband has been changed and available CSC shows INS but active CSC is STH. Now I guess i just need to activate that CSC. I tried the steps mentioned here but it doesn't work.

here is another method you can try. but this only works if your phone supports it.
For firmware that uses a multi-csc code, you need to select a sales code before attempting to connect to a cellular network. This is especially true for 3G and 4G connections.
There are two ways to select a sales code:
1. Enter *#06# in the phone dialer to obtain the IMEI number for the device. You can then enter *#272*Device IMEI# to select a sales code. If your Samsung device does not return a menu, the product code is not a multi-csc code.
OR
2. Install an CSC changer app, such as the "Phone INFO" app. CSC changer apps do require root access, and they do not work on all phones and all versions of Android.
Hit thanks if it helps !
P.S. IT ONLY WORKS ON STOCK ROM ...! so you need to be on Stock Rom.

Thanks for your help. I tried solution 1 and it Worked
However, before trying out your solution, my device was in this state:
1. Flashed Singapore ROM
2. Extracted every file from Indian rom and repacked the tar except the system.img (as this was failing to flash in odin)
3. After booting I got a notification from SupportAgent telling me that unauthorized changes have been made, tap here to reboot to undo those changes
4. I then read your solution and updated the CSC to INS from STH. And device got factory reset and for the first time I saw VoLTE logo on my phone :victory:
5. I finished the setup and still getting the same error in notification from SupportAgent. So I tapped on it, and device rebooted to a new blue screen with sim card logo on it and then boot up to system.
6. Now, in the quick settings, VoLTE toggle is gone and I got WiFi Calling toggle instead. However I still have the VoLTE icon on the status bar.
7. So later that day, I redo all the steps.
- Flashed Singapore firmware (This time, the CSC Country was Singapore and the active CSC was XTH instead of STH. There was VoLTE toggle)
- Flashed Cache from Indian Firmware (CSC Country changed to India the active CSC was INS automatically. Now got WiFi Calling toggle)
8. I noticed other changes in the software:
- The gallery App doesn't show Grid view so I'm stuck with List view
- The Samsung Pay says, its not supported for this device
What do you think about this?

are you still able to use voLTE ?? after these steps.
about Support agent. Ignore it if you can. or skip it. you do not need this as there aren't any official updates after this. (this is only because now system knows that you have modified it, and it will not receive any update. if you can the disable the Support agent app via settings or if possible via root.)
samsung pay will Not work. as knox should have been tripped to 0x1, so Samsung pay like apps will NEVER work after knox trip.

I have a Note 9 SM-N960F/DS model. I bought it from KSA (Saudi Arabia). The phone came with Android Pie (9) out of the box.
Unfortunately my friend rooted my phone and now i am running on "N960FXXU3CSFA/N960FOXM3CSFA/N960FXXU3ASF1" version with "Security patch level: 1 June 2019". I am unable to use my Samsung account and all the security features (finger print, Ratina scanner, Face recognition etc).
When i switch back to original firmware i.e
PDA N960FXXU3CSG1
CSC N960FOXM3CSG1
i got all the features functioning but my SIM card shows "Emergency calls only".
Any help will be highly appreciated. Thanks.

Well, My friend took my phone and told me that he will make it compliant with our local network and make it approved from the Telecommunication authority.
He has downgraded the phone with older firmware version i.e N960FXXU3CSFA/N960FOXM3CSFA,N960FXXU3ASF1. The security patch level is 1 June 2019
I have checked the Knox e-fuse which is not tripped which means its an official ROM and not altered.
Now, i have the latest firmware version downloaded i.e N960FXXS3CSG1 but when i try to install it in my phone it does not recognize my SIM card and phone is in "Emergency calls Only" state.

not sure how you check knox but if he really rooted then its too late and knox cannot state cant be reverted.
typically checking via software is not a good method . going to download mode and checking warranty state 0x0 means is not tripped. anything different means it been tripped/blown.
anyways that dosen't make you phone have no signal though.
i suspect he screwed up the twrp recovery flash procedure for twrp and botched the flash back to stock via odin.
read up on odin and how to use it. get latest version.(search and read)
read up so on how to get latest firmware for your phone and which csc your carrier is so that you can download the correct firmware and have best results for your sim carrier.( in doubt try BTU csc firmware)(but search and read about the subject of phone types firmwares and CSC)
also the firmwares your quoted seem old. not sure why you ended up using it but you should get one that is from july.
E.G.:
https://www.sammobile.com/samsung/galaxy-note9/firmware/SM-N960F/BTU/
(get the most recent! july 25th)( u can dl odin from there too)
on your PC, install samsung android drivers or simply install samsung smart switch. it will install the necessary components.
in it self smart switch can flash firmware automatically for your device. so you might want to try it first.
if you go towards the odin flash route and found the correct firmware or want to try BTU multi csc as suggested above:
put phone in download mode and unzip on PC firmware and flash with odin BL,AP,CP and CSC. But for csc choose csc.md5 instead of home_csc.md5
(be patient while AP is being checked before adding cp and csc)
edit: details steps on odin flashing procedure below

1. Extract (un-rar) the firmware file (i.e. to folder c:\Odin) ***

last but not least don't listen to your friend or let him close to your phone again. reading and searching on xda is much better. everything has been already asked. you just need to search for it.

I haven't try SmartSwitch for N9 but worth to try as it should be able to detect proper csc for your phone.
Else find the latest firmware for your phone with Frija/Samfirm then flash with odin.

well may be your friend tried to change IMEI of phone which is illegal in any country. Match your IMEI with box by dialing *#06#, if IMEI are same then no need to worry. you need to register your phone IMEI with PTA by paying tax. after paying tax they will whitelist the IMEI of your phone and you will be able to make calls.
just for information, my note 9 is also brought from Saudi Arabia, but at that time one device was free, so i got my phone registered by providing my travel details to PTA and they whitelisted my phone.
Please guide me solution.

Hey,
I successfully unbricked my device.
If it fail you are flashing wrong FIRMWAR. HAPPENED TO ME FEW TIMES.

Follow this, it's very safe since you are flashing Stock Rom.
In order to get your CSC regional code you need to contact Samsung. This is really boring since you will have to deal with multiple agents from customer support.
I first contacted Samsung US via Live Chat under support... and they didn't provide any details about product Region at first. So I contacted them few times until they helped me.
YES SPAM THEM AGAIN AND AGAIN.
DONT EVEN SAY YOU ARE NOT FROM US AND DONT MENTION HARD BRICK OR ANYTHING.
So, according to them, my device is for Germanic region (I already knew this, I had some HSH Hotel bloatware).
I contacted German support via live chat and my device is from Austria.
VOILA.
Now that I know which region it is I need to check CSC Region Codes and I made a list.
I searched for them online until I matched codes on the left and Telecoms (carriers) on the right.
Austria (csc codes are on the left and Telecoms on the right):
CSC Regional Codes = Telecoms
AOM = AUSTRIA - unknown /generic probably
MOK = AUSTRIA - unknown /generic probably
TTR = Austria - magenta (former telering/t.mobile)
TRG = AUSTRIA - TELERING
MAX = AUSTRIA - t-mobile
DRE = AUSTRIA - Drei 3 (former Orange)
ONE = AUSTRIA - Orange
MOB = AUSTRIA - a1
ATO = AUSTRIA - Open Austria - directly from Samsung
So, I contacted Drei 3 and A1, I spam them a lot and eventually both agents answered my device is not on their list.
Since my device was SIM UNLOCKED I decided to flash ATO since it's Open and directly from Samsung AUSTRIA.
FIRMWARE
Caution, I didn't like 7.1.1 since I want Root.
So I flashed 5.1.1.
YES I HAD 7.1.1 BEFORE BRICK BUT I FLASHED BOTH 7.1.1 and then I flashed 5.0 for testing purpose. You can chose 1 of them and both are safe.
Click to expand...
Click to collapse
So now that I know which CSC Firmware I want to flash I have to download it. Yes, Firmware is same terminology for Stock ROM.
I downloaded mine from GALAXYFIRMWARE .COM
You could download older firmware if you want, I flashed both for TESTING
I had firmware 7.1.1 and that one I downloaded.
7.1.1 ATO
Then I downloaded 5.0.2 ATO
Choose which one you need.
Then Extract zip in 1 folder.
ODIN
Download unpatched
Patched Odin 3.13.1
For those looking for a modified, modded, or patched odin that is a newer build than all the fake and renamed prince comsy 3.12.3 versions floating around. I patch recent Odin versions to offer similar functionality to the princecomsy; in that...
forum.xda-developers.com
Click to expand...
Click to collapse
I leaved CHECKED AutoReboot and F.Reset
FLASHING
FOR 7.1.1
Now, every file from extracted zip make sure it matches Odin box:
BL file is going into BL slot
AP file is going into AP slot
CP file is going into CP slot
CSC file is going into CSC slot
For 5.0
There will be only 1 extracted file.
It goes into AP slot
Now make sure your Tab is turned off.
If not, remove back cover and unplug battery and plug it back again.
Download mode:
Press Home + Power + Volume Down
(at the same time)
When prompted blue window, press Volume UP
Now connect it to Odin and wait 2minutes to connect.
Start flashing.
If it fail you are flashing wrong FIRMWAR. HAPPENED TO ME FEW TIMES.
PIT FILE
USE This if ABOVE FAILE.
I did not test this.
Okay for some reason you are really in bad position and you really want to flash PIT.
Well you can extract Pit from 7.1.1 CSC.
Copy CSC file to Desktop and rename it to .zip extension:
It will look something like this:
CSC_ATO_T555ATO1CRH1_CL14058996_QB19181858_REV00_user_low_ship_MULTI_CERT.tar.md5.zip
Click to expand...
Click to collapse
Now extract it and look for Pit extension file.
Its something like:
GT510LTE_EUR_OPEN.pit
Click to expand...
Click to collapse
NOW make sure in ODIN Re-Partition is CHECKED.
Now that you have it and you are flashing with PIT.
IN ODIN THERE IS PIT OPTION CLICK ON IT.
IN PIT SLOT PUT PIT.
IN OTHER SLOTS PUT OTHER FILES FROM EXTRACTED ZIP.
Btw if you know how to root this device Android 5 or 6.
Let me know.
**********This is first time am posting a guide so pardon me. *******
********As usual am not responsible for anything that happens to your phone.*******
*****Am not claiming ownership of the above technique, its what worked for me*****
I saw many posts here about people struggling to change csc from skc to koo or international***
Others had issue with their phone suddenly lost network and just displays emergency calls only****
so I have s10 sm-g973n which had csc as koo then flashed skc my mistake. The phone booted with annoying skc boot logo, and branded junk from the carrier. Then one morning the phone couldn't connect to gsm network!
I tried all manner of things to fix it. Rooted with magisk, flashed custom rom nothing.
Tried samkey to change csc still nothing. modified odin in flashing multi csc rom nothing.
Got some luck in changing csc by editing efs/imei/mps_code.dat using root explorer, text editor and vola the carrier junk disappeared. But still no network.
was told only way is to use z3x box or chimera to patch certificate but didn't give up. I posted question here in xda but no guide or response.
But that gave me an idea of what could be the issue- corrupt efs that needs the certificate to be patched. so got keyword.
After watching many YouTube videos I came across a video about a rom that has certificate patched. Just flash with odin and done!
I downloaded and followed the instructions. The phone booted up fine and after going through initial setup the network was back!
Not only did the network came back but the model changed to F, csc became oxm! You can now use tools like Samfw from too to change csc to your local region.
Later in the day, will be flashing firmware with my region csc.
Here is the link to the rom:

Yes sim 2 will work. And after completing flash stock rom for security reasons. Because the above rom is rooted and modified we don't know how secure it is. after network certificates are patched now flash a stock rom from eg sammobile or samfw etc.
When i flash this file the storage becomes 64gb

Did you find a fix for that? For me the internal memory become 32Gb. Is there a solution for that?
I bought an S10 that turned out to be a G973N(SKC) flashed to G973F-D/S(XSG). I think they used this method and these files to do it. I can't get the OEM unlock option to come up. I've tried everything. I am starting to think that it's because of the XSG country code. I was going to try to change it XEU (Great Britain) in SamFW but it just stalls and doesn't do anything. Any suggestions on what I can do here to change the country code? I need that OEM unlock option so I can degoogle it.
Hi guys,
I have I big problem with this rom man, each time I restart my phone i lost network and I have to reflash your rom and factory reset the phone to get it back. It's like it's forbidden to restart the phone, otherwise my network get lost and IMEI Status NG again.. Is there a fix for that? Thank you. Is there a for that fix?
Or do you guys have a rom based on android 12 for g973n u7 converted to dual sim that can solve this IMei STATUS NG? I watched on youtube some guys that have it but it's not free or I can't pay that from here in my cluntry the poorest country in the world.
Thank you guys.
