Hi Everyone,
I'm from Australia and recently bought a SM-G781B off eBay...
Turns out it was a UAE variant and Samsung Pay is all messed up.
I've flashed the phone a few times now using ODIN, trying to get the right CSC correct for Australia (G781BXXU2CUB5) for either of the following CSC's;
XSA (Generic Australia), OPS (Optus), VAU (Vodafone), or TEL (Telstra).
The issue I have is all the Stock Firmware's I've download and flashed keeps registering my CSC as XME (Malaysia)...
Phone INFO app doesn't even detect any other CSC's in the package
I've tried downloading the correct Firmware packs from the following and none gives me the correct CSC for Australia;
https://samfrew.com/
https://www.sammobile.com/
https://samfw.com/
App: Frija Firmware
Does anyone know why this is happening, or can upload/direct me to correct firmware either XSA, OPS (Optus), VAU (Vodafone), or TEL (Telstra)?
I'm totally at a loss now...
Any help would be much appreciated, thanks heaps in advance.
from what I've read recently Samsung has stopped people being able to switch as of android 11.
maybe... I stress MAYBE according to your countryman Hugh Jefferys, if there's a lower version of firmware on the same binary number you might be able to downgrade and then that might mean you can switch CSC.
this is someone who's never even tried changing CSC telling you this so your own research is obviously the only thing to put some faith in.
good luck
XSG (UAE) firmware is part of the OJM multi CSC, whereas XSA/OPS/TEL are part of the OLM multi CSC. This means that it is not possible to simply flash XSA in Odin as the multi CSCs are different, you would first have to use the combination ROM to change from OJM to OLM and then you would be able to flash any OLM CSC firmware, whether that be Australia, Singapore, Malaysia, or Thailand. I'm an Aussie myself, I got my phone from JB Hi Fi but switched it to Thailand CSC since XSA updates are horrendously slow (Samsung Pay does still work on Thailand CSC as does VoLTE/VoWiFi). For your case though, I'm afraid you are out of luck in terms of changing the multi CSC with the combination ROM, if you are on One UI 3.1 then the bootloader version is U2 whereas the combination ROM bootloader version is U1, so you would not be able to flash it anyway. Also, I tried to flash the combination ROM while my bootloader was still on U1 because I wanted to change from OLM to OXM (Romania CSC) for fastest updates, but Odin was not allowing the flash first because of "please get the approval to flash factory images (pit)" which I fixed, then "please get the approval to flash factory images (abl)" at which point I gave up. So as I said before, sorry but I don't think there's a lot you can do Unless a U2 bootloader version combination ROM is leaked which may or may not happen and you can get around the Odin not allowing you to flash it issues, the phone will unfortunately be stuck on UAE firmware (unless there are other countries part of OJM which you could switch to for faster updates).
Hopefully this helps you.
I have the same model! I changed my CSC but for some reason chat features in messaging app doesn't work now..other than that, all's good..

Your software version is was originally XSA, so you wouldn’t have any issues flashing it with XSA and defaulting to XSA instead of another region. The CSC will automatically default back to XSA.
Mine unfortunately defaults to Malaysia XME when flashed with XSA firmware.

Thanks for the detailed reply.
From what I’ve tested, I have no issues with flashing from XSG OJM Multi to XSA OLM Multi. You can do this provided the FIrmware security number is the same as your current revision. You can’t however flash to a lower security value. See image attached.
The current firmware security value at the moment is “2” running One UI 3.1, Android 11. We can’t downgrade to any security firmware version “1” types with Android 10. If we could, then you can use multiple methods to manually change the CSC .i.e through Google Dialer or IMEI trick.
All the Firmwares at the moment are still Muti regional, unfortunately there doesn’t seem to be a way to change the CSC manually even though they are Multi regional.
All XSA firmwares I’ve downloaded and flashed will keep defaulting to XME as that’s the default unless my original CSC was XSA to begin with for it to detect.
I think the only option at the moment is to use SAMKEY, unless someone comes with with a new Android 11 method...
The other option is to root the phone and ADB to change the CSC, however this would trigger and break KNOX securities.
I did check Samkeys update log and they state it’s supported now, this method wouldn’t trigger KNOX;
VERSION 3.63.9 (PLANET EARTH'S FIRST)
- Added support for G780F (Galaxy S20 FE) ALL BIT
- Added support for G781B (Galaxy S20 FE 5G) ALL BIT
- Fixed FAIL(16) on Slow PC's
- Fixed FAIL(20) on G780F
They’re actually up to VERSION 3.71.9 now.
Might be worth a try.

I can confirm SamKEY works on One UI 3.1, unfortunately it is paid but it does work. You can get an account for cheap from eBay with 1 credit on it which is all you need to do the CSC change. Using it I was able to change from XSA to THL (with no data wipe at all which really surprised me).

Trust me you wouldn't want XSA firmware anyway, the updates are terribly slow for it for the S20 FE 5G (not sure about 4G), it tends to get security patches a month after they should've came out, for example it got the March security patch in April which is pretty awful imo. I think it's the slowest CSC in general for the G781B, if you're on OLM multi CSC you're much better off switching to THL where the updates are a lot faster.

That's interesting, I didn't think it was possible to change between multi CSCs like this without the combination ROM (how you were able to switch from OJM to OLM). If you try to switch to an OXM multi CSC such as DBT or ROM from OLM multi CSC, what happens? Does it work? I'll be honest I never tried it myself but didn't have the motivation to try it anyway as I heard it wouldn't work.

Hi There,
Yes, im sure it works provided the security firmware version is the same as I mentioned above.
I also changed to BTU to test.
I can't test for you any longer as I've returned the device for a refund. Will go buy an AUS XSA Variant.
Attached are the images of my original and changed firmware for your reference.

That's very interesting, when you get the XSA variant can you try and see if you are able to flash a CSC such as ROM or DBT on the phone successfully using Odin? I would love to know if it was possible for this to work or not, I'm on THL myself after changing from XSA and did not think it was possible to switch to a different multi CSC (from OLM to OXM).

Yeah that's true no 8GB variant sold here as far as I know not even on the Samsung website and we don't even get eSIM support either
Is there an update/workaround on this issue?
are there any methods that work without samKey?
Noticed that the dialer app that was once able to record calls, is now recording only me talking, since the latest OTA updates on the stock firmware (updated to oneUI 3.1 and Android 11).
I'm also on XSG (OJM) firmware and want to change CSC to enable call recording on galaxy S20 FE 5G (model G781B).
Would love to know how can it be done.

I'm sure by now you've already sorted this, but this is for future people with a need to change CSC
The SamFW FRP Tool can tell you which CSCs are available on your phone already, and can automatically have the CarrierPreConfig service trigger a CSC update. Only need to enable USB Debugging. No root, no reinstall.
But if your phone doesn't have the CSC you need already, download Frija, or another firmware download tool, you'll be able to download and install an OXM Multi CSC firmware (such as XSA, OPS, TEL or VAU), and install it via ODIN tool.
Be sure to select HOME_CSC to keep your data, and backup first.

Hello guys,
I recently bought a galaxy s9 due to it being cheaper now a days. Now, the handset is still on august 2018 patch. There are no new updates available as well. I tried to do a bit of research and found that flashing a rom will be worthwhile. However, the thing is - I have never used a Samsung device before. As such, I am overwhelmed by all these information about CSC, Model number, Build etc etc.....
My device is a SM-G960F, exynos chipset. Service provider is BNG/BNG/XEU. I want to flash one ui on it without much trouble. I have a little experience flashing Oneplus and HTC devices, so the methods are quite known to me. Can u guys help me find which roms are compatible with my device and all that? TIA <3

As I said, pick any region you want, XEU is just the original region of your phone
OneUI comes with Pie, and if you flash one with the June update you'll get the new camera night mode and selfie live focus goodies
Doesn't really matter which region you flash, I often switch between DBT (Germany) and XEU (United Kingdom) as DBT releases updates faster

Thanks a lot bro!!!! U just eradicated my confusion xD
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

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

Is there any way to trick those apps ?
TnxAlot
No there isn't, apps such as these use the phones firmware to determine region, it cannot be changed manually, hence why people who import Samsung devices often cannot use Samsung Pay, your only option is to flash a firmware from your region, however keep in mind you can't flash Exynos firmware to Snapdragon or vice versa

I flashed a DBT (germany) OXM (multi-csc) ROM.
It took the CSC automatically from my SIM carrier I can't do anything about that or can I?

OXM takes the information from the SIM to determine CSC however if you flash a specific firmware that isn't Multi then I think your CSC ignores this, I'm not 100% certain however so I'd do a little research first, sorry I couldn't be of further assistance
I'm currently on an SFR CSC (France SFR) and I want to swap to XEF. Will I be able to get OTA updates right away? OneUI 3.0 for example, it's not yet available for my carrier but it is on unlocked devices.

Hi, I'm also interested in performing this operation, but come on tell me if this invalidates the warranty?
My current firmware is: G988BXXS5BTJ4
I would like to flash this: G988BXXU5CTKG
you can switch csc without problems with samkey. In case of warranty you can switch back. I've done the same for DBT
what do you mean by samkey?
Samkey is the tool to use for changing the CSC.
I did it Friday for the first time on my German (DTM) S20 Ultra and switched CSC to Nordic (NEE).
However, I'm not getting the One UI 3/Android 11 update OTA.
I'm suspecting it is because, OTA only updates the most recent version for that CSC, and the DTM-CSC was 2-3 updates behind.
So Odin is probably necessary in that case to get the latest update.
As the title suggests, I was able to successfully change the CSC on my factory unlocked (unbranded) Fold 3 - F926B/DS bought in Germany with OXM firmware having Android 13 & one UI 5.0 from EUX to INU csc using SamFW Tool v3.31 in hardly 2-3 mins. Kindly note that I also looked into other options to do this like Samkey tool (paid service) and alliance shield app (which doesn't work anymore) etc before engaging with the SamFW Tool as none were simple/working with no complications whatsoever involved.
My main objective to change the CSC was to enable call recording and couple of other features (including some pleasant surprises listed in the end of the post) which were available in the INU csc with little to no hassle. The process was pretty simple, straight forward and most importantly, FREE . It DOESN'T require any factory reset, flashing of roms or wiping cache partition before or after the process.
The step by step guide process which worked for me is as follows:
STEP 1: Click here - SamFW Tool Download - to download the latest version of SamFW tool.
STEP 2: Remove the sim card and connect your phone to a computer and make sure the phone's drivers are installed.
STEP 3: Unzip the downloaded file. Right click on the file SamFwFRPTool.exe and 'Run as Administrator'.
STEP 4: After the software opens, make sure your phone is detected before proceeding. If its detected, click on ADB tab in the software.
STEP 5: In your phone, go to developer options and enable 'usb debugging'.
STEP 6: In your phone, open phone dialer and type *#0*# to get into test mode. Leave the phone unlocked and keep it aside now.
STEP 7: Click on 'Change CSC' button in the ADB tab of the tool. Now the tool will connect to your phone, check and list the available CSCs which your phone model supports as shown in the pic attached.
STEP 8: Choose a CSC which you wish to change to from the drop down menu in the pop-up window as shown in the pic attached.
NOTE: The tool also has the option to force the phone to accept a CSC not listed/supported as well by manually entering the same. However, I would not recommend doing it if you really wish to get OTA updates and also to evade any unforeseen issues. I must admit, I haven't frankly tried this and do not know what lies in the pandora box to be honest.
STEP 9: After choosing the CSC from the drop down, the tool quickly connects to the phone, changes the CSC and restarts the phone.
STEP 10: After the phone restarts, unlock the phone using your pin/password, insert your simcard, check the change of CSC in software information, disconnect the phone from the computer and also disable the 'usb debugging' in the developer options.
That's it! All done. Phone restarts with the new chosen CSC and the related features will now be active!
BONUS: There is also an option in the ADB tab in the SamFW Tool named 'Battery information' which gives the complete information of the battery status including the 'charge/discharge cycles' along with its temperature, voltage etc. like in the pic attached. Do note that the information shown in the 'Genuine battery' section isn't correct for some reason and always shows as 'NO' for any phone with/without genuine battery.
With my choice of INU csc the following major changes/surprises were noticed over the EUX:
1. Call recording and a couple of other INU specific features are now enabled (google for more info on what csc enables what features).
2. Not sure why but Battery backup has increased significantly after the csc change to INU. SOT (Screen On Time) which has fallen to 3-4 hrs after the OTA update to One Ui 5.0 & Android 13 is now back to 5-7hrs or more.
3. RAM management has definitely got better. With EUX csc it used be around 5-6GB during standby and now its always around 3-4GB when the phone is idle.
4. Instead of 4G or 4G+, now it shows LTE and LTE+.
5. Mobile data speed has increased both in 5G (Jio True5G network) and in LTE+ when compared to EUX CSC.
6. 5G signal strength has improved drastically. Signal loss or switching to 4G+/LTE+ is very low now.
7. 5G to 4G/LTE switching while calls (VoLTE/VoNR) is more seamless now. Latching back onto 5G network after a call is a breeze now unlike earlier with EUX csc.
8. Phone definitely got faster for some reason. Can very much feel the difference when switching between apps, multi-tasking, even opening/closing apps and other day-to-day tasks.
etc...
Haven't tested whether the OTA updates will still get pushed after the change in CSC yet, as my phone is already updated to the latest patch as I write this. Should absolutely work IMO as long as we choose a CSC which the phone supports but in any case will update the thread once the next update via OTA is available/pushed by Samsung.
Disclaimer: Please be informed that all the above information is purely based on experience of using the tool for changing CSC only which worked well for me with my Fold 3. Cannot take responsibility if it doesn't work for you.
Does it work for Fold 4. Want to change CSC from Korean Region to INU (India). Please guide
Sorry, haven't tried it on Fold 4. Logically it shud work, I guess. There is no harm in connecting n checking what CSCs does ur model supports using the tool IMO.
Tried out but it does not work. It shows only the Korean csc. Even that seems to be not changing
Oh k. I think the tool works, else u wudnt b seeing the CSC which ur phone supports.
I have checked sources in the web as well on this and looks like Fold 3 or 4 with Korean CSC supports only CSC from Korea.
I guess u can still force a CSC on to it replacing the Korean one but thats too risky as u will b missing OTA updates and im not aure wat all things it will mess up.
Awesome! It works and it doesn't wipe the device. I just switched from G975U VZW to CCT without any issues.

Happy to hear that. BTW I also got samsung pay/wallet to work as well by installing its apk file today after changing the system language to a local one specific to the changed CSC i.e., English (India) for INU CSC in my case.
I confirm that it is working on a stock android 13! Great tool!
(It worked on the second try though )
Has anyone tired it on a Fold 4, Mine is XAA and I want to convert it to INU. Haven't been abe to do it as yet.
Let me know if someone finds a way, mine is a US version and I want to convert it to the India CSU.
Thanks in advance

Oh great. Getting otas after the change?
Does OTA work after change?
Hello, can somebody please briefly summerise the options for switching the CSC/Firmware?
I read other threads and this one and now am confused which method actually would work for me.
My situation: i have a Samsung A52s 5G purchased from Deutsche Telekom in Germany, sold separately, not bundled with a contract.
And i am having a contract with a different carrier on a different network, but a german SIM card.
My phone is configured all english, and i need to keep that.
Because of assumed network optimisations and the problem of delayed updates of "branded" phones, i would like to convert the phone from the current CSC of DTM to the DBT using fimrware (A528BXXS1DVL2/A528BOXM1DVK5/A528BXXU1DVK5/A528BXXS1DVL2), which i hope would link me to updates directly provided by Samsung.
I found "https://forum.xda-developers.com/t/...official-firmware-all-samsung-device.2697238/" and "https://forum.xda-developers.com/t/...-multi-csc-codes.4436853/page-5#post-87485577 ", but i am not sure whther the methods described there only apply for UPDATING (within the same CSC) the phone with non-OTA methods, or whether that also covers SWITCHING the CSC?
In the end i have two questions:
1) So far i believed that "simply" putting an official stock Samsung firmware (multi CSC in my case, containing the DBT, but apparently NOT containing the DTM) would bring me there.
But then i read that this might not be suffficient. Instead i also would have to switch the CSC in my Phone's config, which apparently would require purchasing a license for a Samkey unlock code.
Because otherwise i would not receive any OTA updates once i switched just the firmware.
Is that actually true?
I would prefer not to have to buy a Samkey...
And to make the confusion even bigger: now i read, SamFw Tool would also be an option?
But: is that trustworthy? And: from posts of some of you: this might even obsolete to switch the firmware, do i understand that right?
2) If switching firmware still is required: would using Odin/Heimdall be the only option to switch the firmware, or would adb sideloading do the same job as well? I am asking because i don't have access to a windows machine.
Would be so great if someone of you could untangle my confusion a bit, thank you.

Did not automatically receive the OTA updates with the recent DVL9 update. However, tried a work around to change the CSC back to EUX via the same tool (which is a 2 min task) to check if I can get OTA again.
And yes it worked! immediately after changing the OTA to its home CSC, was able to see OTA in the updates section of the phone. So, I updated the phone to the latest version (DVL9) and then changed the CSC back to INU after the update . All is well and quick! .

May be TUR csc has restricted options/features. In my example after I changed to INU csc (India one) all the India related options got automatically activated like call recording, spam filter, samsung pay using cards etc etc. which weren't available with the EUX csc before the change.

Any potential issues using INU csc in the UK? I use Samsung pay already but native call recoding would be really useful for me

Might be worth clearing cache and data from Google play services see if that helps. Having the same device with 2 different cscs might have confused Google
Edit
Any reason your Google play store is out of date or is it connected to your original issue
