Hello everyone, I just got my G960F/DS and it originally came with SIN CSC so being I am in Canada, I tried to load the UK firmware to try and get VoLTE and WiFi calling to work. I was able to on SIN CSC, to select BTU firmware from the phone app using the secret code, but stupid me didn't discover the one thread about to use XEU to get the WiFi calling option and now I am stuck on BTU CSC without the option to go to XEU. I read if you use ODIN to go on H3G and then use ODIN back to a OXM based ROM, that it will go by default to XEU, but for me it just kept the BTU CSC after the firmware was flashed.
Does anyone have any suggestions? As mentioned above, no secret codes on the phone app I read to access the CSC changer or the advanced phone info is currently working. I can't flash a custom ROM as I am on the 7 days wait so wondering if it would be best to wait the 7 days and just flash a custom TW ROM with the CSC I want?
Thanks.
You can't switch between XEU and BTU easily, if at all as they are MultiCSC and one contains the other, BTU contains XEU
Not sure why your phone would default to BTU if you were flashing XEU from a completely different CSC not included though unless your phone was originally BTU
Make sure you're using CSC and not HOME_CSC when you flash and remove the SIM for the flash
Flash back to SIN then to XEU using CSC in ODIN both times

Yeah the phone originally showed SIN as the product code for Singapore. When I got the phone, I did originally try flashing the G960FXXU1BRF8 BTU ROM with the CSC (not HOME_CSC) with ODIN, but after setting up the phone, the CSC stayed at SIN. The only way I was able to set it to BTU was using the phone secret code of '*#272*IMEI#*' which now being on BTU, that no longer works to switch to XEU. Is there any special steps I should be following to switch CSC's properly? I did the following so far to try and switch
- Flashed H3G BL, AP, CP, CSC using ODIN (kept default ODIN options with SIM card and SD Card removed)
- Let the ROM boot up and went back to Download mode to flash the OXM BL, AP, CP, CSC
- After the firmware was flashed in ODIN, booted into recovery mode to factory reset/wipe cache.
- Inserted SIM Card and SD Card and let the ROM boot which indicated BTU as active CSC and Product Code.
Hope these details help. Do you know if the SIN firmware is a non-OXM or is it part of the OXM-multi CSC?

Thanks for providing this. Do you know why when I flashed the H3G firmware which is a non-OXM CSC, why flashing to a OXM after, caused the Sales and Product Code to stay BTU? As described in my last post, I flashed the BL, AP, CP and CSC for H3G and it did boot, but I immediately shut off the phone and installed the OXM firmware after it did. Does my SIM Card have to be inserted during your steps? Lastly not sure if it's true but I read that whatever your product code is, the OXM CSC will apply that CSC during the first boot. So I have to find a way to change the Product Code without using the phone secret code since that no longer works on BTU firmware.
I usually do my research before doing anything like this to prevent issues and have installed custom ROMs, changed CSC since the S2 days, but this has me stumped.

If I had to guess, (if your phone is 2nd hand) then the original CSC was actually BTU and not SIN, SIN was flashed before it was sold
If that's not the case, then I'd guess that BTU always defaults from OXA Multi unless your CSC is included, which would mean you do not know your original CSC and SIN was still flashed before sale
Otherwise I have no idea, I haven't tried changing my CSC on the S9, I know with the S7 I had before this, the same problem occurred trying to switch between XEU and BTU, my S7 was XEU and refused to switch to BTU
SIM only needs to be removed for the initial flash and first boot from what I know, otherwise it can use the SIM to work out the original CSC

Yeah I kind of figured. Phone was brand new and the Samsung seal wasn't broken but when I did boot it up for the first time, I didn't get the setup screen. I know with my S5 my product code was switched and even when flashing Canada's CSC, with my SIM installed, it would default to a different CSC then what I needed. The only way to change it was using the Phone's Secret code. It's a shame that it's not easier to change the product code so that the proper CSC is applied.
Does anyone who has the BTU product code have the same issue with the secret code not working? I am on the same version of ROM that I was on before my CSC got changed to BTU so I know it's not the ROM version. Every guide I found regarding flashing CSC has been to get to BTU not to get to XEU so anyone who can shed light on this? In the meantime, I will wait the 7 days for OEM Unlock to appear.
So I got the OEM unlock last night after 154 hours uptime but it was 7 days since signed into Samsung account and I did try XEU and INS CSC but no voLTE. Was wondering if anyone on Rogers or any of the Canadian carriers have gotten voLTE or wifi calling to work? In the past I know INS CSC did have voLTE for the s7 when it was a S8 port but so far trying INS, SIN, BTU, or XEU CSC hasn't worked. I am happy with RR AOSP right now, but wanted any suggestions as there must be one CSC that works.

Hi Andrw0830,
Can you please advise how you did manage to change the CSC back as required to XEU? I also by mistake changed my CSC from STH to BTU via secret code and now the secret code is not working and I am stuck with BTU CSC. Does the OEM unlock has to do anything with it ? Appreciate your feedback ? Thanks

I waited the 7 days to enable OEM unlock. Then I installed TWRP and installed the devbase ROM which has the choice to change the CSC. You do have to copy the options.prop that's included in the ROMs zip to your SD card before flashing the ROM. Then open up the file and there is a line for CSC, change it from KCSC to XEU. Save the file and install the ROM which will install the CSC you chose and the first boot will have it enabled.

Thanks a lot for your quick response and guidance. I was looking at options where I do not have to necessarily flash a custom ROM and somehow change the CSC. Nonetheless, can you please advise further if the KNOX count/warranty is void after you performed this flashing and is there a way to reset these counters ? Thanks again.

Unfortunately, once you flash a custom recovery, the KNOX is tripped and there is no way to reset.
ok thanks for your feedback. I will go and check with Samsung Service center
Hi All,
I have tried searching for a solution to change CSC Code on a rooted G960F BRI model but all threads are about changing it without root (and that doesn't work).
Can someone point me to a thread maybe, that provides the steps to change CSC on a rooted phone?
You should be able to change it without root as long as the new CSC you are flashing does not contain the phones original CSC
For example BTU is Multi_CSC and contains XEU, so if your phone was originally XEU and you wanted to try and switch to BTU you cannot because the phone will automatically choose the original CSC from the Multi_CSC
You would need to flash a CSC that is either a single CSC or does not contain BRI
Look on the play store for CSC changer for a root method

Hey Thanks for your reply....I am currently on BRI and wanting to move CSC to XSA but XSA being single CSC and BRI multi CSC I think it is not possible yet....
I've tried to debrand my phone by flashing open market firmware (XEO, Poland). I downloaded the newest version of Odin, flashed it but now my CSC under settings says OPV/OPV, OPV/EUX/OPV. OPV is my carrier's CSC, I'm wondering what that EUX is. I've looked it up on Google and it seems like I'm not alone, seems like Samsung changed something and older methods no longer work. The question is - will I still receive updates released for my carrier or I'm screwed for good? Phone INFO app says my active CSC is OPV. I'm running S20+ 5G (G986B) Exynos variant.
Same problem here, I've flashed it with XEO POLAND G986BXXU1ATBM firmware using Odin3 v3.14.1_3B_PatcheD, few minutes later it showed "PASS" and nothing changed. Same branded firmware after reboot..
It seems, that many more 'branded' CSCs are now part of Multi-CSC. For me, this is DTM (T-Mobile DE). It osed to not be part of multi-CSC but it is now part of OXM.
This means, that you can not force it anymore, as you already ARE having the exact same firmware with the 'branded' CSC. Just checked, OPV is in deed part of OXM now.
In the Ultra Section is a thread showing the CSCs belonging to OXM: https://forum.xda-developers.com/ga...galaxy-s20-ultra-g988b-firmwares-5g-t4060443/
I have not yet found out / gotten an answer from anybody how to change CSC. Samkey also is not supporting the S20 series ATM - dont know, if this will change.

What I have worked out is that when you flash a multi-CSC firmware file you end running the CSC one letter earlier in the alphabet out of the. Available multi-CSC list
E.g. I had a VOD branded S105G and flashed BTU firmware, and ended up with TEL CSC
I also tried flashing BTU on an H3G branded A70 and ended up with EVF CSC
The original branded product CSC also never changes

Enable Developer mode and set OEM Unlock to ON before trying to change CSC via ODIN Flash
This should not be necessary? Doesn't that trip Knox, despite original Samsung Firmware?

Since now it's part of Multi CSC, does that mean I will receive updates faster? I can see other polish carrier's CSC are listed as single so I assume they are kind of separate firmware, am I right?
Honestly I do not know, if the respective CSC will be getting OTAs at the same time.
However, you can always flash manually with HOME_CSC, that is true.

Enable OEM unlock does not trip Knox. As long as you flash official Samsung firmware files in Odin Knox is never tripped
My own personal experience on S10 and above is you cannot flash a different CSC with OEM Unlock disabled
(Flash completes successfully but CSC doesn't change)
When changing from one e.g. branded csc to multi csc with the S10+, this worked fine without enabling oem unlock. Well, anyway. Flashing OXM multi CSC over OXM multi CSC will not change anything, right?

I found that you have to be on a single CSC before flash to multi-CSC and also you don't always end up on the CSC you expected
e.g. Flash BTU on a VOD product and you end up on TEL CSC (one letter in alphabet below VOD) and not on BTU
did everyone succesed DEBRAND ?

Hi. I have S20 Ultra SM-G988B/DS, it's International model, original CSC is VAU, and I installed OXM CSC Firmware, I use it in United Arab Emirates with XSG CSC, but it also shows XFA CSC, idk why. After updating to OneUI 5.1, i can only see eSim option for 2nd sim but 2nd Physical sim is not working and nothing in the settings. I tried to change the CSC but no luck. Kindly help
