If your device is SM-S908N (as I can see LUC in blurred picture) - it is not possible to change CSC at all for N (South Korea) models.

Also no call recording CSC for N, U, U1, W and 0 models.

Only B or E models!
[Samsung Galaxy S22 Ultra] Sami man:
The thing is I am using the Korea version of S22+ and I want to change to the US version of CSC but that isn't supported should I manually type the CSC and proceed and what will happen to my warranty if I do?
[Samsung Galaxy S22 Ultra] DaOldMan:
Forget it. After restart the csc will change back. Not possible. You can change to csc in your rom only.

Sorry.
[Samsung Galaxy S22 Ultra] Sami man:
Okay is there any way to enable the esim feature.
[Samsung Galaxy S22 Ultra] ChoSmile:
No way. You can switch only between CSCs inside your model. For N models even forbidden by Samsung.
[Samsung Galaxy S22 Ultra] Sami man:
So there isn't a way for me to enable the esim feature.
[Samsung Galaxy S22 Ultra] DaOldMan:
Probably not. Maybe you can root it and then get esim on a custom rom, if one exists. But this will introduce new problems like Samsung pay, Samsung health not working. Banking apps problems. Google pay work arounds... Sorry.
[Samsung Galaxy S22 Ultra] Sami man:
I wouldn't want to root my phone as you've mentioned some, it has a lot of downsides I'll just sale this phone and buy a new one. Thanks for the assistance though.
[Samsung Galaxy S22 Ultra] rk3v:
Hi, I like to change my CSC on my Korean SAMSUNG Galaxy S21 Ultra (SM-G998N) to Indian version to use esim (Now only 1 physical sim, no e sim option, sim manager is not visible). Already out of warranty, so i can try any option as long as it dont brick my phone. i googled, but most old posts says cannot change csc of korean version. I am new to this. Any option to get a esim? thanks a lottttttt
[Samsung Galaxy S22 Ultra] Sami man:
Have you tried to change the CSC using Samfw tool.
[Samsung Galaxy S22 Ultra] rk3v:
No. i was confused. in Samfw tool, which option should i select to change CSC. Under ADB or under Root
[Samsung Galaxy S22 Ultra] Sami man:
The option under ADB.
[Samsung Galaxy S22 Ultra] rk3v:
Tkss. it says "

Checking ADB connection...

No ADB connection found

"
[Samsung Galaxy S22 Ultra] Sami man:
Talk to me on telegram on @Xda_help2023 I'll walkthrough you the steps.
[Samsung Galaxy S22 Ultra] rk3v:
ok will ping u. i enabled debugging. now it is shwoing few CSC. but dont know which CSC has esim option.

Available CSCs are KTC | LUC | SKC | KOO | WWD. first 3 of them are koreans. so wont work. any idea about last 2 = KOO & WWD ? does it has e Sim option?

KTC = Korea (KT Corporation)

LUC = Korea (LG Uplus)

SKC = Korea (SK Telecom)

Updated. Hi, I like to change my CSC on my Korean SAMSUNG Galaxy S21 Ultra (SM-G998N) to a CSC which support esim (Now only 1 physical sim, no e sim option, sim manager is not visible). SamFW tool says Available CSCs are KTC | LUC | SKC | KOO | WWD. first 4 of them are koreans. so wont work. Any idea about WWD CSC. 1) which country it belongs to 2) will it support eSIM 3) will it disable any existing apps-Gpay,Bank apps or cause any other issues 4) will CSC Change reset my phone and have to install and configure all apps and data again? Thanks a lottttt
[Samsung Galaxy S22 Ultra] ChoSmile:
WWD is for shops (demo phones)

CSC change (did not erase/reset anything) but for N models (S. Korea) it is FORBIDDEN by Samsung (not changing by any paid or free apps).

Only ROOT (if find a way) but most apps stops working. No security, bank, payment, some games, a lot of staff... there is a root hide but it is temporary until Google catch it... cat and mouse game... Butter buy other international model.
[Samsung Galaxy S22 Ultra] MrDusan:
I am trying to download the samFW tool 4.6 but from where ever i download it I get my antivirus triggered with different types of trojans that are in the installation file. From where do you guys download it? Thanks.
[Samsung Galaxy S22 Ultra] hogger33:
I am planning to change CSC on my A34 5G (EUX version) with SEK version via SamFW? It is possible?

I would like to use call recording.
[Samsung Galaxy S22 Ultra] DaOldMan:
Use SamFW to check which CSC are availible for you in the rom. Then you can know which one you can change to.

Cheers.
[Samsung Galaxy S22 Ultra] ChoSmile:
No, SEK is part of SM-A346E.

There is no CSC with call recording enabled for A34 (SM-A346B)
[Samsung Galaxy S22 Ultra] sbassios:
Hello,

I have the s23u.When i choose the SEK csc i have rcs messages,when i choose ILO or INS i dont have it...is there any solution for rcs messages with INS csc or ILO?i want the call recording, spam call and the rcs messaging
[Samsung Galaxy S22 Ultra] ChoSmile:
My S23U INS use Messages by Google with RCS support (need to be activated inside app). I preffer it instead of Samsung Messages app.

Google Messages - Apps on Google Play

Simple, helpful messaging by Google

play.google.com
[Samsung Galaxy S22 Ultra] sbassios:
via google messages i can send rcs messages,but i am used to samsung messages application thats why i am asking
[Samsung Galaxy S22 Ultra] DaOldMan:
We use ilo here in Israel. No one uses sms here anymore. It's used mostly for password confirmations. Everyone uses whatsapp or telegram. We have no idea why Usa is stuck in 1897 using useless SMS system. Try to send 2gb file through that, or original photo without compression, edit your message, send voice message, video message.. and much much more.

For SMS don't use Samsung messages, it's useless. Not only there is no rcs support in ilo, they also have bad message filtering. We use Google messages for that, it filters spam very well.

Cheers
[Samsung Galaxy S22 Ultra] sbassios:
i am trying to get used at google messages!!send original photo without compression via google messages?
[Samsung Galaxy S22 Ultra] DaOldMan:
That's why we don't use sms at all. You can't send original pictures, voice memos and much much more. We all use only whatsapp or telegram here. With them you can do what you want.
[Samsung Galaxy S22 Ultra] sbassios:
You cant send original picture via whatsapp while you can send it via rcs samsung messages
[Samsung Galaxy S22 Ultra] DaOldMan:
You can via telegram. Rcs is nothing compared to all features those apps have. No idea why people still use it.

Samsung doesn't support features in Israel. No Samsung pay or rcs....
[Samsung Galaxy S22 Ultra] JohnnyC73:
The CSC region of my Galaxy S23 Ultra is XAA, which of these options has call recording, spam filter and VoLTE?
[Samsung Galaxy S22 Ultra] sbassios:
I tried to send via telegram original picture but unfortunately it compress it like whatsapp
[Samsung Galaxy S22 Ultra] DaOldMan:
Because you didn't learn enough about telegram. In order not to compress it you need to sent as a file, then choose gallery and then the picture. Zero compression.
[Samsung Galaxy S22 Ultra] soul18reaver:
did anyone else lost the ability to use google pay on their device ( SM-S908B/DS exynos, had changed last year CSC to SEK) after the update to S908BXXU4CWE1?

more info: seems that it has only a few CSC available now and I get the message that the device doesn't meet security requirements and in google store the play protect certification says device not certified
[Samsung Galaxy S22 Ultra] DaOldMan:
Delete Google play and Google play services apps data. Restart. If you are not rooted it should be certified again.

Cheers.
[Samsung Galaxy S22 Ultra] soul18reaver:
thanks, tried but sadly it still sees my s22 as not certified;

also the safetynet test fails on CTS profile match
[Samsung Galaxy S22 Ultra] ChoSmile:
Samsung miss to authorised their ...WE1 in Google Play Protect. (Happens many times with a lot of devices. First time on my Note20 I write and call Samsung... until any understood and answer me the next firmware comes.)

Options:

Wait Samsung to release next firmware ...WEx (x>1) or ...WFx

Downgrade via ODIN (AP, BL, CP, HOME_CSC) to ...WD3 (and turn of temporary OTA updates).

P. S.

Nothing other helps (delete, uninstall, even factory reset on this firmware), just firmware did not pass GPP. The chance Google to reauthiorize it is small than Samsung to push the next firmware.
[Samsung Galaxy S22 Ultra] soul18reaver:
ok, thanks for info.

I will wait for the June update
[Samsung Galaxy S22 Ultra] Lj9211:
I'm from New Zealand and I got SM-S918B XNZ in my Samsung s23 ultra. which CSC should I change to enable the call recording ?
[Samsung Galaxy S22 Ultra] redcom7:
But how is this possible? Samsung did so big mistake?

I believe was in purpose

to stop call recording....
[Samsung Galaxy S22 Ultra] ChoSmile:
INS, XXV, ILO, SEK, and not recommended at the mement THL

It's part of firmware. They just can remove. Someone miss to do part of procedure. Happens many times on many phones.
[Samsung Galaxy S22 Ultra] redcom7:
If i cahnge csc to one of these (INS, XXV, ILO, SEK) and make a system restore you think that i am going to be ok?

With call recording and Google pay?
[Samsung Galaxy S22 Ultra] ChoSmile:
No, if already updated to to WE1 you can to restore, return to previous firmware because bootloader is 2 (prevous firmware is with 1).
[Samsung Galaxy S22 Ultra] emfjop:
I have experienced the exact same problem... I updated 1 week ago to the latest version and suddenly (yesterda) safetynet fails.

I have tried to downgrade via odin to the previous version and still experiencing the same problem (enabled hiding apps and installed sensitiveprops+safetynet-fix.

Did anyone managed to fix it with a downgrade?

DEVICE: samsung s21 fe (g990b)

Thanks a lot
[Samsung Galaxy S22 Ultra] ChoSmile:
My second phone S22U SEK CSC updated OTA to problematic WE1 and Play Protect said "Device is not cetified" in Google Play Store.

Because previous firware WD3 is still same bootloader "3", I just downgrade with ODIN (BL,AP,CP,HOME_CSC) and and status changed: "Deivice is certified" it is not needetd to install any "sensitiveprops" or "safetynet-fix". If device is with official firmware, no root, no knox tripped, no mods, Play Protect automatically verifies device and status become "certified".

* * *

For S23 series THL CSC updated OTA to WEA is is not possible to downgrade because bootlader of WEA become "2" and previous firmware WD1 have lower bootlaoder "1". So for S23 users have to want next newer firmware for certification fix.
[Samsung Galaxy S22 Ultra] redcom7:
Thank you i was about to downgrade today..

With s23+.... Time for nothing..

Do you know about every how many days they update the firmware?

Sorry i am on samsung s23+ and Android after 2 years with ios...
[Samsung Galaxy S22 Ultra] ChoSmile:
Once a month for new phones. (In rare cases more than once.)
[Samsung Galaxy S22 Ultra] emfjop:
Thanks for quick reply. Wow, it is strange. Can you please tell how the downgrade process would be with magisk installed? I got bootlooped yesterday many times, untill i formated the data (I mean, if I use the home_csc file won't work, but if i use the normal CSC it will format data and work)

Thanks and best regards,

Pablo
[Samsung Galaxy S22 Ultra] gpap2004:
Which CSC do you currently have? Because in EUX firmware that i had before, Cube ACR did nothing .
[Samsung Galaxy S22 Ultra] saturn3000:
However, usually if you are in a noisy environment such as on the street you cannot hear the recorded voice of the person you are talking to.
[Samsung Galaxy S22 Ultra] renek11:
Well, if you have another working app for the Galaxy S22Ultra, here it is.
[Samsung Galaxy S22 Ultra] saturn3000:
There are no applications that works for call recording without changing CSC, it is a system lock.
[Samsung Galaxy S22 Ultra] eddiedimitris:
Hello

I have sm-s9080b and before 5 days I change csc from eux to ilo in order to have call recording and hiya...everything goes right.I did it with samkey and it was perfect....but 2 things.

1)Before Ilo I changed to Egypt (Egy) but it has not hiya for call blocking...just thinking in Egypt the do not have exclusively snapdragon edition?How I manage to make it to my Exynos?

2)I have a problem with samkey and they can not help me....I try to go from ilo to Egy and the process stops when it goes to connect with their server and says fault ...do you know what happens?One from samkey told me to factory reset my phone but before do this has this happened to you?

thank you
[Samsung Galaxy S22 Ultra] tomesiek:
When you change to ILO you may experience a different stock calendar (saturday is on red - if you know what i mean).

Just try to switch off your antyvirus and firewall, also make sure that developer mode is switch on on your phone.

God luck
[Samsung Galaxy S22 Ultra] eddiedimitris:
Yes you are right the red is on Saturday...do you believe that this is causing the problem?How can I fix this?
[Samsung Galaxy S22 Ultra] tomesiek:
I think because in ILO is jewish calendar.
[Samsung Galaxy S22 Ultra] eddiedimitris:
Can you please give me an idea how can I solve this in order to use samkey again?
[Samsung Galaxy S22 Ultra] tomesiek:
I think that the only option is to use SEK CSC and install Hiya as a spam blocker. Other way, there is a big chance that we not get a OTA update*.

Please check that you got adb.exe in SamKey folder (my antyvirus remove this everytime when i was installing SamKey, need to switch it off before i want to use SamKey). Also check if developer mode is switch on on your phone. Basicly all basic before you use SamKey

* i read on a different forum (hope is not true) that all other CSC with native call recording in EUX firmware are there "accidentally" .
[Samsung Galaxy S22 Ultra] eddiedimitris:
Do you believe that If I stay with israel firmware I will not take OTA updates?
[Samsung Galaxy S22 Ultra] tomesiek:
My believes got nothing to do. If Samsung release firmware for ILO then yes if not... we need to wait. But.... for now there is no seperate image for ILO and there is one for SEK. So... lets just wait and see
[Samsung Galaxy S22 Ultra] eddiedimitris:
In this case I think the only solution is

to change csc via Odin
[Samsung Galaxy S22 Ultra] tomesiek:
via SamKey. Odin is for installing a firmware
[Samsung Galaxy S22 Ultra] eddiedimitris:
Because I can not use samkey that's why maybe flash other firmware is a solution ....do you know if via Odin I could flash whatever firmware I want?

p.s.

Sending data to SERVER...OK

Waiting for SERVER response (May take few minutes)...FAIL(bad)

SamKEY Team (2017-2022)

thats what samkey responds
[Samsung Galaxy S22 Ultra] tomesiek:
Edit post and cover Imei and serial nr. I think that is just because servers SamKey are litle overload right now. Try late at night or morning. I'm almost sure it's just temporary.
[Samsung Galaxy S22 Ultra] eddiedimitris:
it is 3 days now i have this problem
[Samsung Galaxy S22 Ultra] eddiedimitris:
So me With Exynos will I take updates with ilo firmware?
[Samsung Galaxy S22 Ultra] emfjop:
Sorry, the message was not sent correctly.

Is it possible to downgrade a system without losing data? The problem came because I downgraded using the home_csc file.

Thanks and best,
[Samsung Galaxy S22 Ultra] ChoSmile:
Downgrade from official to official firmware via PC with ODIN and all 4 files: BL, AP, CP and HOME_CSC will preserve data. (Only HOME_CSC most probably will corrupt data - all must be same version).

If you have magisk, so your phone is (or was) rooted, or custom rom, or custom recovery, anything else modded - so there are no guarantees for data preservation during the downgrade.
[Samsung Galaxy S22 Ultra] Nikishek:
I confirm the problem with problematic firmware.

S22, CSC SEK, firmware WE1, and can't use Google Pay ("Device is not cetified"). For me, the solution is to hold on and wait for the update. In the meantime, I'll switch to the European CSC EUX.
[Samsung Galaxy S22 Ultra] redcom7:
.? And if you switch to EUX?

Is Google pay going to work?
[Samsung Galaxy S22 Ultra] Nikishek:
What is your opinion on SamFw? Virustotal says it is full of trojans. Their website doesn't look very legal, you need to run it as admin, and after installation it "looks for an update", if you block this connection, the program won't start at all, ip leads to Colombia - another suspicious thing.

Is it worth it to you?
[Samsung Galaxy S22 Ultra] ChoSmile:
No. It is same firmware. Just different features enabled/dissabled depending of active CSC.
[Samsung Galaxy S22 Ultra] ChoSmile:
If question is to me.

I keep several older SamFw versions.

3.31 is the latest that works without internet (blocked internet access)

Still shows a problem on Virus Total but no problem found several months usage.
[Samsung Galaxy S22 Ultra] ChoSmile:
Meanwhile:

On my old S22 (SM-S908B) on SEK CSC with WE1 with GPay problem (not certified), downgrade via ODIN to WD3 (certified), now again updated OTA to WE1 - shows CERTIFIED on Google Play Store, Safetynet Test - PASSED.

Might be a miracle... Google Play Protect updated. Will see.. . 😁
[Samsung Galaxy S22 Ultra] DaOldMan:
You will get June update in few days, so just wait.

Cheers
[Samsung Galaxy S22 Ultra] soul18reaver:
an update:

after I updated google play store to the latest version( google play store->settings->about )

and also updated the google play system with the latest (wasn't available 2 days ago)

(settings->about phone->software information-> google play sistem update)

I have the phone now as certified with WE1 :D
[Samsung Galaxy S22 Ultra] redcom7:
Nothing here with csc THL.. that no works
[Samsung Galaxy S22 Ultra] Nikishek:
There was no need to switch the CSC. Overnight, an update came to Google services or Google Play. Everything works with same SEK CSC now.

I can confirm that. Still on WE1 and SEK CSC. Google Pay is working from today again.
[Samsung Galaxy S22 Ultra] redcom7:
Hi all..

Did anyone here... manage google pay work with THL CSC?
[Samsung Galaxy S22 Ultra] urbanman2004:
So I've owned my Samsung Galaxy A54 5G, the "SM-A546U" model for almost a month, and it currently contains the "TMK" CSC. I haven't done any in-depth modding to a Samsung device since 2017 when I last owned my Galaxy S7 due to Samsung's anti-consumer practices, but that's besides the point. I'm not trying to root my device, but I want to enable native call recording which is currently missing on my device so I would like to know if there is any way possible to force my device to support a certain CSC that will enable this feature. Any helpful advice would be welcome and I would greatly appreciate it.
[Samsung Galaxy S22 Ultra] DaOldMan:
This is a usa model. There are no csc in the rom that enable call recording.

For that you buy the international model, but then you may have problems with the frequencies.

Sorry mate
[Samsung Galaxy S22 Ultra] leosoftstudios:
So the same answer should be also fit on A546B (European) model right?

Because there is no CSC in EUX rom that enables the native call recorder. Is this correct?

And in that case, from A54 5G models only the A546E (Asian) version is able to carry native call recorder by changing an appropriate CSC. Am I correct again?
[Samsung Galaxy S22 Ultra] Sherlock29:
Can you tell me which is the best CSC for call recording? Like is there a big difference in OTA delay between SEK and INS for example? And other than that is there any other difference? Thanks in advance.
[Samsung Galaxy S22 Ultra] DaOldMan:
For which model?
[Samsung Galaxy S22 Ultra] Sherlock29:
S23 Ultra
[Samsung Galaxy S22 Ultra] ChoSmile:
INS - call rec, call ID/spam, SPay

THL - call rec, call ID/spam, no SPay

XXV - call rec, SPay, no call ID/spam

SEK - call rec, no call ID/spam, no SPay

ILO - call rec, call ID/spam, no SPay

When any CSC firwaware will be pushed OTA is decided by Samsung. No plan which CSC will be first. Sometimes same day, sometimes several days, sometimes never. (Example latest THL released first but no other pushed.)

Which is best - everyone decides for himself/herself.
[Samsung Galaxy S22 Ultra] BlueMeany68:
Sorted.
[Samsung Galaxy S22 Ultra] emfjop:
Hello friend.a new update has appeared for SM G990B Sek region. How can I check before updating if this will happen again? How can I check if it passed GPP?

[Samsung Galaxy S22 Ultra] sbassios:
Does xxv support rcs messages via samsung messages?its the only i havent tried
[Samsung Galaxy S22 Ultra] ChoSmile:
Maybe it is supported but depends if SIM operator support RCS, better use Google Messages which support RCS on all operators, CSCs and countries (except where Google services are not allowed).
[Samsung Galaxy S22 Ultra] sbassios:
unfortunately it doesnt support...why samsung doesnt support rcs(samsung messages) and samsung wallet everywhere?
[Samsung Galaxy S22 Ultra] verszipo:
i don't knwo about RCS, but for why Samsung Wallet doesn't work everywhere, well there are a lot of legal requirements and agreements that need to take place before you can use Samsung Wallet (or Google Pay or Apple Pay for that matter). For example for Romania it took quite a while for Google Pay to be avaiable because it took a long time to get aggreements from the government and the banks from RO.

Also, not all banks want/care to support a payment system, for example Raif... only allowed their cards to be added to Google Wallet in the last month even though Google Pay was available for about 2.5 years (it got activated somewhere in November of 2020).
[Samsung Galaxy S22 Ultra] ChoSmile:
Any of the *Pay services (Google Pay, Samsung Pay, Apple Pay, Garmin Pay, Fitbit Pay, Huawei Pay, Wena Pay, Mi Pay, ... and etc.) have to sign a contract between them and the bank to represent their bank cards - separate/infidudual for any conuntry, any bank, any *Pay service.

If there is no at least one bank in a country that have a contract for example with Samsung Pay service - the "Samsung Pay" app is not available to download and install in that country. Even you change the CSC or doanoad the desired *Pay apps in your phone - if your bank do not have a contract - you can not digitize your card.

.

Ask and insist in your bank to sign a contract with desired *Pay service.
[Samsung Galaxy S22 Ultra] Red_Baran:
Sorry for the ignorance. I've been having a hard time sorting through all the information. Can this be done on an SM-G988U, with the latest firmware?
[Samsung Galaxy S22 Ultra] Yakuzahi:
Hey need help

I have SM-S908E with call recording but in the US SPAY, WIFI CALLING VOLTE not working. Can I install any other CSC that have all those options working?
[Samsung Galaxy S22 Ultra] ChoSmile:
No. Sorry, there is no CSC with Call Recording enabled for US models (U and U1).
[Samsung Galaxy S22 Ultra] ChoSmile:
Call Recording + SPay for SM-S908E try INS or XXV.

If Samsung Wallet missing - install it from Galaxy Store (for supported CSCs only).

Abour VoLTE and VoWiFi - check if you have needed APN(s) for your mobile operator, at least "ims" type and "xcap" type for ussd support.
[Samsung Galaxy S22 Ultra] bizkit_120:
Hello ChoSmile, I have A54 us version (a546u ) is possible by swapping csc enable call recording? Or any workaround? Thanks in advance 🙏
[Samsung Galaxy S22 Ultra] ChoSmile:
Sorry, no CSCs with native Call Recording feature enabled for any U model.

Workaround is root but most Knox tripped, no warranty, security apps, bank apps, some games stops, there are modules to hide root but on any new firmware must be updated... if there is a way current firmware to be rooted.
