Did you manage to change your CSC version via *#272*HHMM* ? It changes the CSC region setting and hard reset the device.
It is also possible that you flashed a firmware with an unique CSC.

Yes, I change my CSC version via *#272*HHMM*. My phone show THL but kies show KOR.
My firmware is S8500DXLD1/S8500OLBLD1 (bada 2.0 official firmwares for some Asian countries like Thailand,Vietnam, Malaysia.)
Sorry, my english isn't good.

please clear Kies registery to make it think that you are connecting a new device

You have to choose the correct ROM first. So if your phone is SM-A505F you need that ROM. Not recommended to use other ROMs like SM-A505 FN, G etc.
Once you have the correct ROM (must be newer than your current) use Odin 3.13 or newer to flash your phone . before flashing do back up and then remove all accounts!!! Then remove your SIM and memocard and do hard reset. Connect to Odin in download mode and flash. Wait till its completely finished and boot up your phone. 1st boot can take up to 10 minutes, once you see the Start screen insert the SIM card from desired region and let the phone restart again.
My phone for some reason picked up CAC product code (Uzbekistan). Flashed latest ROM inserted my Vodafone SIM and after restart my phone was on BTU (UK unbranded).

is flashing different CSC ROM will trip Knox

I my case this method for FN version did not worked any different way to do it?

No it wont trip knox as long as you are flashing official samsung firmware.

OK I investigate a bit today
looks like I was able to change CSC from ROM to FTM (Freanch Orange) using brand Orange from Poland (OPV) - all was done with JUN patch the same patch level files
I would like to change from ROM to XEO (Poland unbranded) and for this I did not found any way to work

I think that it's somehow let you change the CSC only one time... I recalling that I was able to do it on my A50 and A70 but only one time...

in my case it is more like I can change to branded CSC like orange or T-Mobile ( did this few time) but it not give me Poland as a country
I cannot change to unbranded CSC like XEO - it always show ROM as active CSC (softwanre CSC it is showing XEO) but for example news I have from Romania

typically it will remain as whatever sim you have in the phone.. there are tricks u can do.. id search some more as theres many csc related threads.. also make sure that csc u want is actually included on the device already since if it doesnt exist then well you cant use it until u get the right csc..

You didn't say what region you want. In my case I was after UK (BTU) or Germany (DBT).
Do hard reset (sim and memory card remove). Turn on phone without sim and wait until it says No sim inserted. Insert the sim from region or country you want to have on your phone.
Make sure you have multi CSC ROM. In my case it was ok. Changed from CAC to BTU.

There's no LTE/4G only mode. So if this is what you want no need for flashing different ROM.

You need multi CSC ROM. First time boot up without sim and memory card. When boot finished will tell you insert sim. I think Samsung set up phones to allow ONLY one change and only first time...

how to Update using ODIN

Hello
i don't know if this question was asked before i tried to search but nothing
i came from xperia xz and flashing was just as easy as downloading the FTF and flashing in flash mod
i bought my S9 that was stuck at 1 Dec 2018 software and no new updates are available (even with smart switch) to download so my best solution is to update it manually using ODIN
i used to have a galaxy gear watch and s5 and flashing was also simple but i came across a thread that said something about CSC Version and i am sacred that i may brick the phone while trying to update it
can someone point me in the right directions ?
my CSC : G960FOXM2CRLI
Service provider SW ver.
SAOMC_SM-G960F_OXM_KSA_PP_0002
KSA/EGY, EGY/XSG
baseband version
G960FXXU2CRLI

PPR1.180610.011.G960FXXU2CRLI
and i live in egypt but the phone was sold is KSA if that's matters
any help please ?

If there are no updated KSA firmwares for your S9, flash any CSC for the G960F, Germany (DBT ) has the latest June update

If you have KSA sim card need to flash KSA firmware with only Home CSC also and if you have EGY sim card and will come OTA downloads
KSA/KSA,KSA/XSG

Well yes you need CSCs to match for OTA, but it is not necessary for normal usage, once my region releases the latest update I will flash back for OTA

so it's normal to flaash any firmware even if the CSC doesn't match? only the phone model number right? flashing on ODIN like thr normal way kust like the s5? nothing else need to be done ? like enabling/disabling stuff on developper options ? OEM unlock? sorry for my noobies questions

Normal if your own region CSC has not updated their firmware yes, but you will not receive OTA updates until the CSCs match and will have to flash manually each update
There is a big thread about it so I'm not going to go into it in detail here, quick search should find what you need
Nothing else needed, boot to download mode and flash with Odin 3.13.1

Is it safe to flash A505F firmware on the A505FN device? As far as I know, the only difference is NFC.
And is it possible to void the warranty by doing this?
I tried Smart Switch a few times, but no updates.

Hi thanks for your reply.
Should I need to remove all accounts, and make a factory reset first?

Smart Switch only will provide you the newest firmware in the same line, not an option to use other different firmware from a different region.
Ever is recommended to do a factory reset/format data before to "switch" to other firmware and make a backup before to restore it in just minutes with SS.
Install Phone Info(Samsung) and there you will find the CSC availables for your device before to change the firmware (most of the international models are multi_CSC compatible), search for the regions and compare them here https://www.****************/2017/0...specific-product-code-csc-and-country-region/ if some of them is convenient for you then you can flash it, check before your bootloader version, I think all are now in v1 but check it before to go further.

Yes, you usually can (I switched a lot of times) but you could find some issues regarding to radio/baseband depending on how different they´re.
Take a backup before using Smart Switch, take note of your actual firmware in a safe place if something goes wrong and don´t forget to enable USB debugging and OEM unlock before to go.

Good yes already did a backup and OEM Unlock and USB Debugging are one.
I'm simply waiting the firmware to be downloaded. Take very long time to download from samfrew

I forgotten to remove my Sim Card but even that it has changed the CSC.

My model is A505F. I don't think you may install F on FN. It may work but you may have several problem with correct functionality of the phone or even brick it.

F firmware on an FN device should be ok afaik, but I believe you'll loose NFC
Also keep in mind that INS csc has this string in cscfeature_network.xml
<CscFeature_Message_ConfigImeiTracker>+919560345888,+918424098931,+919176905802</CscFeature_Message_ConfigImeiTracker>
I remember that this was a problem on custom roms for the old A-series since all roms for some reason added INS csc, so a bunch of users in europe got charged extra for messages to india if they didn't remove that from cscfeatures..
Not sure if it still acts the same, but I can confirm that the string is there in INS csc for A50.

There is finally firmware with July patch for FN versions of this device, so probably I'll wait few days, because only 5 countries in Europe got an update to the newest version, skipping June security patch, but I hope we'll have new features in the camera.

SM-G781B - CSC: XSA (Generic Australia), OPS (Optus), VAU (Vodafone), or TEL (Telstra)

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.

Yes, im sure it works provided the security firmware version is the same as I mentioned above.
I can't test for you any longer as I returned the device for a refund. Will 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).

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).

Wish I tried it before returning the device. The Australian stock only has 6GB RAM and no dual-sim....

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.

thanks!

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.
