SEK would be great but it doesnt have callerid spam protection sadly. It has callrecord and chat features.

I dont like the google messages. That is why im using samsung messages.

If anyone knows a CSC which has: callerid spam protection, call record and chat features it would be great
[Samsung Galaxy S23] danieldeak70:
If a software update comes it will change to INS ifts on INS or it still be EUX ?.

Like right now its: ... INS/INS,INS/EUX/O2U

Will it change to: ... INS/INS,INS/INS/O2U or it will be still EUX INS after update?

So i have this and the latest version of December patch security with android 14, if i change to INS may i lose the OTA ?
[Samsung Galaxy S23] ChoSmile:
ONLY FIRST CSC can be Changed via SamFw, it is "Active CSC", OTA updates comes when pushed for this "Active CSC".

It doesn't changed the n update comes. Doesn't change even when flashed via ODIN other firmware from same MultiCSC (if the Active CSC is part of this MultiCSC.)

Next two (comma separated) are SIM1 and SIM2 - it changes to Active then sim exist.

Penultimate CSC is region made for (non changable).

Last one is country/region/operator manifacured for (non changable)
[Samsung Galaxy S23] ChoSmile:
No. You are already on Android 14. OTA will work and receive updates when new update is pushed for INS.
[Samsung Galaxy S23] nikriaz:
Dear @ChoSmile, thank you for your great contribution to the topic! Could you please look on this?

Two years ago I bought new S21 SM-G991B and immidetely changed CSC from SER to XXV to have call recordings. I see I used SamTool, credits bought through Ebay and Odin. I don't remember all details, tho. Never did anything special with phone later and never been on any betas, only regular OTA.

The phone worked flawlessly, including GPay and CR till last week when I received large UI 6 update, immediately followed by small security update. Since then Google Play marked "Device is not certified", GPay says "Phone does not meet security requirements" and SafetyNet reports "CTS Profile mismatch".

Current status is:

G991B_OXM_XXV_14_0003 XXV/XXV,XXV/SER

Version: G991BXXS9FWL4/ G991BOXM9FWK3 / G991BXXU9FWK2

Tried all common recommended things like cache partition wiping, GServices data/cache deleting etc. No joy.

Tried to install Samsung Pay (first time on this phone). Seems work but only shows compatibility with Vietnamese bank issuers while I live in Europe, so useless.

Not sure what does mismatch what and what to do?
[Samsung Galaxy S23] Arzee08:
Re-Add your card again
[Samsung Galaxy S23] nikriaz:
It's a joke, I believe. Just in case if not: it's impossible because GooglePay does not meet all mandatory requirements.
[Samsung Galaxy S23] ChoSmile:
Two options:

A)

Wait for next Samsung firmware (or Google authorise it meanwhile before next Samsung fw)

OR

B)

Download via Frija or SmMobile website or SamFw website EUX firmware for your device, flash it with ODIN (BL, AP, CP and HOME_CSC without data loss), CSC stay same. OTA will stop. After next XXV released have to download and flash again and OTA will work again.
[Samsung Galaxy S23] Arzee08:
It wasn't a joke. I came from the beta and on the official ota firmware it did this till I re added my card. Don't know about the safteynet stuff but it is for sure correct. I mean it 2 seconds to try doesn't it.

Edit - I understand you didn't come from the beta but is worth a try in the meantime
[Samsung Galaxy S23] nikriaz:
@ChoSmile, thank you very much! I suspected this. Will wait some time, if not resolved by itself then will go by (B).
[Samsung Galaxy S23] strongkoya:
which one from thos include call recording " ACG | AIO | ATC | ATT | CCT | CHA | DSH | FKR | GCF | LRA | SPR | TFN | TMB | TMK | USC | VZW | WWD | XAA | XAG | XAR | XAS "​
[Samsung Galaxy S23] ChoSmile:
None of SM-XnnnU1 models (U/W also).
[Samsung Galaxy S23] saturn3000:
At present, for the S23 Ultra SM-S918B with CSC EUX, what is the CSC that allows to have both call recording and anti-spam and allows to have OTA updates even after the CSC change?

Thanks.
[Samsung Galaxy S23] ChoSmile:
I can CONFIRM for "B" region devices (Europe, Asia, Midde East, ...)

S24 (SM-S921B)

S24+ (SM-S926B)

S24 Ultra (SM-S928B)

CALL RECORDING WORKS !

CSC change is still working with SamFw. (no data loss)

CSCs with call recording: INS, THL, XXV, ILO maybe others but also.

INS - CallRec, CallID, SPay

XXV - CallRec, SPay

THL - CallRec, CallID

SEK - Sorry, did not check personaлly, there is no SEK in S24/+/U devices.

ILO - CallRec, CallID, SHM

(CSC changes are not limited)
[Samsung Galaxy S23] MajkPL:
Also possible on S24? Because the processor is different in EU. Possible Only SEK?

So as not to be left with a brick later.
[Samsung Galaxy S23] ChoSmile:
There is a lot of misunderstanding about what exactly is changing CSC.

The processor (or other hardware part) does NOT matter.

What matters is (software) which CSC regions are written into CSC section of the firmware. These availalble CSC regions are the SAME for the three "B" models S24 (SM-S921B), S24+ (SM-S926B) and S24 Ultra (SM-S928B).

SamFw just give command to SWITCH only between these AVAILABLE CSCs, it is not percisly "change" but "switch".

This switch enables/disables (shows/hides) different features (depended on switched active CSC) that EXIST in ALL fimwares.
[Samsung Galaxy S23] saturn3000:
At present, for the S23 Ultra SM-S918B with CSC EUX, what is the CSC that allows to have both call recording and anti-spam and allows to have OTA updates even after the CSC change?

Which is the best CSC for timely updates and which doesn't upset other things on the phone like holidays in the calendar or the way you dial phone numbers? SEK - ILO - THL ?

Thanks.
[Samsung Galaxy S23] ChoSmile:
In SEK, CallID (anti-spam) was includen in Android 14 for S22 series, it was missing in SEK at Android 12 and 13.

!!! There is no SEK is S24 series devices. Sorry!!!

Never try it in S23 series.

Other with CallRec and CallID are THL, ILO, INS.

Which is "THE BEST" depends of people's needs.

(For me is INS - CalRec, CallID, SPay, Digikey)

!!! There is no SEK is S24 series devices. Sorry!!!
[Samsung Galaxy S23] saturn3000:
Do OTA updates for INS CSC arrive faster than others?
[Samsung Galaxy S23] ChoSmile:
Samsung depended. There is no rule. Most of the times EUX is first. One or two times INS was earler... but generally 2-3 days later, maybe several times longer.
[Samsung Galaxy S23] vampysol:

I got S23u from US whose model is S918U1. Can I flash this phone directly using Odin for INS ROM?

Should I flash first or enable 5G bands for JIO Sim first?

Will I get call recording facility by just flashing INS ROM?

Do I need to also switch csc to INS after flashing ROM?

Edit: maybe more correct question is should flashing INS ROM on S23U US S918U1 model will work using Odin?
[Samsung Galaxy S23] ChoSmile:
It's not possible to flash cross models firmware (B on U1).

May be low level flash in service center via some box or jtag but normally not possible via ODIN (or if is possible via USB - I didn't know how).

Sorry there is no CSC in USA (U/U1) and Canada (W) models that have Call Recording feature enabled.
[Samsung Galaxy S23] panu123:
I tried actually flashing using Odin but always getting "secure check fail: pit" error. Good that this attempt saved phone from bricking due to that error.

Just to understand this error, does this come because U1 bootloader is locked?
[Samsung Galaxy S23] ChoSmile:
Inquisitive users proof protection :)

Even unlocked you can not flash different model.

Firmware must be signed for correct device. Even custom firmwares (if rooted) are for exact model. Otherwise the device become "brick".
[Samsung Galaxy S23] zuberek48:
Hi Cho,

I just went through the whole thread, very informative btw.

I have a

S23 Ultra SM918b_OXM_EVR_14_0002

EVR/EVR,EVR/EUX/EVR

updated to Android14.

I want to unblock native call recorder and I am thinking to change csc to ILO or INS.

ILO - advantages: CallRec, CallID, SHM - and disadvantages: Fridays and Saturdays marked as the weekends instead of Sat/Sun

INS - advantages: CalRec, CallID, SPay, DigiKey - and disadvantages: before changing csc I have to block below numbers

+919560345888

+918424098931

+919176905802

In both cases OTA will work as I am already on Android 14.

Like I mentioned above I need native call recorder, other options not really important for me.

Should I use SamFw FRP Tool version 4.8.1 which is available for download from samfw.com

or SamFw_Tool_v3.31 (most of available online versions full of trojans).

I have never change csc before so I want to make sure I did't miss any important info.

Which csc in you opinion will be better for me ILO or INS?

Thanks
[Samsung Galaxy S23] ChoSmile:
What is better or best for someone is a matter of individual needs and preferences. It's INS for me.

3.31 is latest that do not need internet, after that app requres internet to check and update itself to lates version, if internet rejected - it close itself).

All version(s) shown that they have trojans (but they don't have or false positive). (This version is 100% like mine, used since ocober '22). If you scare of trojans - use paid option: Samkey, 1 credit needed per 1 change (for example: can buy samkey credit from ebay 1 is ~$5, 2 are ~$9).

Spoiler content hidden.
[Samsung Galaxy S23] zuberek48:
Thank you
[Samsung Galaxy S23] zuberek48:
hi,

Just recognized that blocking the number doesn't prevent phone to send text message to this number.

Do I need to setup someting extra? thanks
[Samsung Galaxy S23] ChoSmile:
Manual send via messaging app is not blocked by phone block list (generally it is for incoming calls and messages), but internal send to India number is also blocked. Me and friends using India CSC for years on many phones are without any "passed" messages (checked in detailed bills).

P.S.

Anyway, even if you don't block them "1 international sms sent" ONCE on a new sim card is a few cents (everyone can afford it).
[Samsung Galaxy S23] zuberek48:
Hi,

I have just changed CSC to INS and all ok, Thanks again
[Samsung Galaxy S23] czerwus:
hello everyone,

I bought Samsung Galaxy S23 and updated to Android 14, OUI 6.0 (Poland)

Now i have Service provider software version as in teh photo below.

Can I change the CSC to one that supports call recording?

View attachment 6063245
[Samsung Galaxy S23] ChoSmile:
Yes, to any of these: INS, SEK, ILO, XXV or THL.
[Samsung Galaxy S23] nguyenlucky:
@ChoSmile I thought Samsung pulled out of Ukraine (SEK) due to the war, but Samsung SEK website still shows the S24 series.

I also bought a Shield Pro account, change CSC to both EUX and EUY with Samfw and use Shield Red app to change Country ISO, but Ukraine isn't in the country list either.

Not sure what happened to SEK CSC 🤨

Note: Country ISO is only relevant for EUX/EUY CSC.
[Samsung Galaxy S23] ChoSmile:
I download and unpack CSC firmware file (even before I receive my phone) HOME_CSC_OXM_S928BOXM1AWM9_MQB75606875_REV00_user_low_ship_MULTI_CERT.tar.md5.zip

Inside in AVAILABLE CSCs are there is NO SEK for S24 Ultra (SM-S928B) model.

"CSC change" apps just sent command to SWITCH to desired CSC and even some of them have option to "write your own CSC" - the phone is resposible to SET the "Active CSC" and it is set only if this CSC is part of available CSCs inside. (There was an exeption for S22 B models for several firmwares for INS (which was part of S22 E model) but it was deprecated.

So, in the current situation, the first (and the only) S22 series firmware available is S92*BOXM1AWM9 - No SEK CSC inside to switch (change).

Maybe in next firmware Samsung can add it.

The firmware ...WM9 is just not an usual one (it is pre-installed) W means year "2023" and M means month "13".

There is test firmware ...XA7 on the go ... which means 2024 January... so will wait for release and will check if SEK is included.
[Samsung Galaxy S23] corepda:
Hi guys,

I was on XSA ROM but I changed the CSC to INS for call recording. Since I have done that last year, I have not been able to receive any ROM upgrade for my device, which is pretty disappointing. Everybody else on XSA is on Android 14 with Touch UI 6.0, and I’m still A13 & on 5.1.

Can someone please provide instructions on how to upgrade to the latest version of the ROM? Appreciate your help in advance. Below is the screenshot of my device software for you to give me exact idea on the next steps. Thanks again

1706958154401.jpeg
[Samsung Galaxy S23] ChoSmile:
What it "was" is irrelevant.

What is current CSC (you change to)?

What are the EXACT current versions? Dail *#1234# and share it here.

Also from Settings > About phone > Software information > Service provider software verion - shere here both lines?
[Samsung Galaxy S23] corepda:
Thanks mate, here is the screenshot from my software section from the *#1234#
[Samsung Galaxy S23] corepda:
I just updated my post. Thanks mate
[Samsung Galaxy S23] ChoSmile:
Both XSA and INS was on different chanels at Android 13.

There is no ...WF1 on INS, so that why there is no OTA.

They become united at Android 14.

To fix this you can download latest firmware ...WL3

Download Galaxy S23 Ultra SM-S918B (INS) S918BXXS3BWL3 in Samfw - Samsung firmware download

Galaxy S23 Ultra SM-S918B (INS - India) S918BXXS3BWL3 U(Android 14) samsung firmware download all model, lastest, fast update, completely free and fast speed in Samfw.com ✅

samfw.com

You need to flash via ODIN - BL_, AP_, CP_ and HOME_CSC_ files.

(use ODIN 3.14.4)

(CSC_ files not needed, its for reset)

Phone will be updated to latest firmware, also will have OTA when next firmware is relesed. No data loss when HOME_CSC_ file used.

(If you do not know what is ODIN flash and how to use it - do a search in XDA forums, explained many times OR find a friend to help you do it remotely instead of you.)
[Samsung Galaxy S23] corepda:
Cool thanks mate, I'll give it a try. Cheers
[Samsung Galaxy S23] nguyenlucky:
someole told me SEK will be consolidated into EUY (Europe non-EEA) using Country ISO. As of now, there's no country ISO for Ukraine yet when switching to EUY (checked with paid Shield Red app). Finger cross
[Samsung Galaxy S23] sealed:
Hello. Does anyone know which CSC can enable 5G SA and VONR option in model 918B? Xiaomi can enable these by using dial code, I don't know where I can find these options including developer options.
[Samsung Galaxy S23] ChoSmile:
Like EUX and EUY have many localisations for different EU contries NONE of them have "Call Recording" enabled. So, even on EUY will be added Ukraine localisation - it WILL NOT add "call recording". Only on separate CSC (SEK) can expect differet feаtures, if added at all.
[Samsung Galaxy S23] ChoSmile:
No, Samsung don't have such option disable carrier ckeck for differet features (VoLTE, VoNR, VoWiFi, ...) like Xiaomi.

Only Samsung can enable this feature by adding it in next firmware if your mobile operator inform Samsung that VoNR is supported for their sim cards.

OR

Root (but there are a many disadvantages).
[Samsung Galaxy S23] nguyenlucky:
Before the EUX countries are consolidated, none of the have call recording I think. I already bought Shield Red and will try when SEK/Ukraine ISO comes out.
[Samsung Galaxy S23] Samsunga:
Probably.
[Samsung Galaxy S23] saturn3000:
It would be useful to know for S23 Ultra, version B, what are the differences between the various CSCs and what is lost by using them in terms of functionality.
[Samsung Galaxy S23] enebro77:
Anyone here from Spain ?

Which CSC should be the one to change into ?

SEK looks like being the one, as long as it has even sPay ....

Anyway, thanks for confirming
[Samsung Galaxy S23] gpap2004:
SEK doesn't have SPay. Only INS has.

INS doesn't support HCG and blood pressure monitor on Samsung Health smart watch 4 and 5
[Samsung Galaxy S23] eddiedimitris:
Has csc to do with hd call?
[Samsung Galaxy S23] gpap2004:
Yes. THL and INS don't support Vodafone's Greece HD call. When you answer a call you don't see the HD on the call screen.

But with SEK everything is normal
[Samsung Galaxy S23] eddiedimitris:
So for me in Greece only Sek is my choice right Although I have Cosmote...In an older s21 I had Ilo(Israel) but I do not remember if I had Hd call....I am waiting for samkey to support it in order to change csc
[Samsung Galaxy S23] gpap2004:
ILO has not so often OTA updates , but you can still update through ODIN with a EUX firmware.

INS is the firmware I would like , but it's not working some health functions on galaxy watch (although you can mod it with Dante22 trick).

Why you are waiting Samkey while SamFW is way better? I used to change csc with Samkey and still have credits but I tried samfw and is a lifesaver!
[Samsung Galaxy S23] eddiedimitris:
Can you give me an easy and specific guide to do it? I've never done it this way before. Only with samkey. Have you installed Sek on the s23 ultra?
[Samsung Galaxy S23] gpap2004:
Yes , I used samfw for first time in my s23 ultra. The procedure is very easy and safe. I tried INS but then I changed to SEK for the reasons I explained before.

In short:

1. You enable ADB in your phone

2. You download samfw to your windows PC and run it.

3. Connect your s23 ultra with the PC through a cable.

4. Run samfw , and press Tab adb in the program (it is the third tab in the upper place of the app).

5. You will see a pop up menu with all available XOM multi- csc .

6. Choose and right in the appropriate box the one you want (INS ,SEK etc).

7. Press "change csc"

8. It will appear a prompt saying dial *#1234#* (or something like that ) while the screen of your phone is looking like being in check mode( like the one you have in Samsung Member app when you want to make a check for some function).

9. That's it. In seconds you have your new scs without data wiped!
[Samsung Galaxy S23] eddiedimitris:
First of all thank you very much!After this do you believe we will have normally OTA updates ?
[Samsung Galaxy S23] TODI1111:
I used SEK csc instead of EUX csc in S22 ultra. The OTA updates came fine.
[Samsung Galaxy S23] harry552:
Hey Guys,

I am importing a S23 Ultra from Australia to India, thus wanted to know will changing the CSC Initiate region lock, Also can i receive OTA updates when we change csc from XSA to INS or INU ( Also, whats the difference between the two)?

Thanks in advance
[Samsung Galaxy S23] gpap2004:
Yes, we will have OTA updates normally, because SEK EUX and INS are part of the same OXM multirom which take the same updates
[Samsung Galaxy S23] gpap2004:
No , you will not have OTA updates, because Australia rom is different from OXM multirom .

You will have OTA updates only if you change your initial CSC to the one that is part of this multirom rom.

IF , you change to INS from XSA (XSA was your rom that initially came with your phone) , the only way to have updates is manually through ODIN ( that means , you can download INS firmware once is available every month and manually add it to your phone)
[Samsung Galaxy S23] zorbakun:
Hey Guys, If I imported a S23 from Spain, would it work in the Middle East? would changing CSC help overcome the region lock if any?

[Samsung Galaxy S23] gpap2004:
Sorry, I don't know it.

But no need to unlock the bootloader in order to change CSC
[Samsung Galaxy S23] eddiedimitris:
I would prefer THL or INS because they have built in Hiya...the fact with HD+ i consider...Is it sure that they do not support this?I think Egypt csc supports call recording too
[Samsung Galaxy S23] zzattack:
Are there benefits to SEK when already rooted? Skvalex works fine for me.
[Samsung Galaxy S23] efsanevii:
Hello guys, can anyone help me out which CSC is best suited for the S23 Ultra so that it will receive updates from OTA, ECG will work actively and also for spay, call recording and spam? Thank you...
[Samsung Galaxy S23] czerwus:
Well... i switched from PRT (Poland) to ILO and everything works just fine. Bun now I have some questions.

1) Are ILO updates avaible for me or will be updatet with PRT, or maybe updates are unavailable after CSC change?

2) Spam protection will protect me form PRT or ILO spammers ? (living in Poland)

3) Can I switch back to PRT or maybe this is one time thing?

4) Does factory reset switch me back to PRT or keeps with ILO ?

5) Does this process broke my warranty ?

Will be gratefull for answers :)
[Samsung Galaxy S23] ChoSmile:
No such CSC.

INS or ILO - both have CallRec and CallerID/spam but only first have SPay, only second have SHM (Samsunsung Health Monitor).

OTA update ... WHEN your selected CSC (INS or ILO pushed by Samsung.
[Samsung Galaxy S23] ChoSmile:
Almost all questions are answered in the threads but most people demand personal attention they do not have time to use search.

1. When ILO OTA update pushed by Samsung.

2. database is for all

3. unlimted (or unless Samsung removes option to change)

4. No, nor factory reset, nor ODIN flash with firmware if your currect CSC is part of the MultiCSC (list of CSCs inside firmware). Can be switched to desired another CSC (part of the MultiCSC) OR ODIN flash with SingleCSC (have only one CSC) firmware like XID .

5. No. It is SAME ORIGINAL FIRMWARE (SAME FILES) just some features/extras existing in it are shown or hidden depending of CSC (region permits/bans and requirements).

@Cho,

Hi, How are you doing, I would like to update the CSC for my Canadian Galaxy S23 Ultra. Want to have call recording. Could you please suggest any CSC.

If i install Indian OS will it effect any thing to my device?
[Samsung Galaxy S23] ChoSmile:
Sorry, no CSC for your phone model SM-S918W, (also for all Canadian W and US U/U1 models).

It is not possible to install different model firmware (B on W), even with almost same hardware. (Maybe in service center on low level via box it's possible).

The only way is root - but it broke knox, no warranty, most security apps, bank apps, some games will stop working, even hide root have to be updated often when google catch "hide").
[Samsung Galaxy S23] jack_mac2:
any other alternative way to record calls?
[Samsung Galaxy S23] ChoSmile:
- Root (with many disadavtages)

- Cube ACR form Galaxy Store (if still works recording from microphone, means that volume must be high or speakerphone to "catch other side")

- external device as Bluetooth Call Recorder
[Samsung Galaxy S23] Rakaan:
Does changing CSC require resetting the device or is it something which can be done easily on the fly? Thanks
[Samsung Galaxy S23] ChoSmile:
Answered MANY times :)
[Samsung Galaxy S23] Rakaan:
I am sure it has been but there is too much information and all scattered. At some locations, it says need to reset and at others, someone mentions, no need to wipe the data. Looking to update the CSC from XSG to INS without wiping the data.

Thanks 🙏
[Samsung Galaxy S23] czerwus:
changing CSC does not reset your phone. All data and settings remain intact.*

* - settings related to the CSC you want to use could change.
[Samsung Galaxy S23] Rakaan:
Thanks a lot. Also, would the OTA updates be received without any issues?
