Yes, confimed. Google pay worked just fine... :)

I have YASNAC showing CTS profile match: PASS with the versions I posted before.
[Samsung Galaxy S23] ChoSmile:
So, options are wait, check for Google updates or Samsung updates. Or flash EUX (BL_AP_, CP_, HOME_CSC_)
[Samsung Galaxy S23] lukatino:
@hvihavai

What version of google wallet do you have?
[Samsung Galaxy S23] hvihavai:
24.20.637707351
[Samsung Galaxy S23] Fritz-67:
It seems to be working again. I haven't changed anything. The CSC is still CSC SEK, I haven't changed anything. The YASNEC test suddenly worked successfully. Google Wallet no longer shows any errors either.

[Samsung Galaxy S23] lukatino:
Hi, on my side same as before, all updates installed, I am on THL and YASNAC failed

Hi @ChoSmile I have been wondering, what if I BEFORE those additional updates of playstore, wallet, services, changed the CSC back to the original one? It would all be working properly now?

Do you have any suspicions why it doesn't work for me but works for others?
[Samsung Galaxy S23] ChoSmile:
No, it will not chnage anything about GPay.

Changing CSC just SHOWS/HIDES different features and extras - allowed/forbidden in the CSC region.

To fix GPay - check for Google Play update (alredy fixed for S23 series ...XDE.) or flash all files with ODIN from working files.
[Samsung Galaxy S23] lukatino:
Hi Guys

I just want to let you know that I manage to solve the issue (did not check gpay at shop yet). So what I did was a

1) disabling the google play store app on my phone

2) running the YASNAC with no error (!!!)

3) turning on the google play store app

4) another check with YASNAC and it works!!!

One questions:

What I noticed the "Evaluation type" in YASNAC changed from BASIC to Hardware_Backed - anyone knows why is that and what does it means to me and my phone?
[Samsung Galaxy S23] Trifenix:
it's not the solution.

google has done some update in play service, and after that yasnac return to work and gpay too.
[Samsung Galaxy S23] bastoun19:
Hello, I am in CSC INS, instead of EUX originally. now that the problem is resolved with Google Pay and the XDE version, in your opinion, for the next update, should I switch back to XDF or do you think that now everything is OK with XDE? Thank you for your help.
[Samsung Galaxy S23] xclub_101:
The issue was solved in fact with updates from Google a few weeks back but apparently now we have the June update and is again different - from what I see on reddit "EUX update is CXE9/CXE3/CXE3 but ILO update is CXE7/CXDE/CXDE".

Any experience with that?
[Samsung Galaxy S23] ChoSmile:
On my old S23U phone with XDE after problem with GPay I flash to XDF. Meanwhile they fix XDE. Now I decide to skip flashing wirh ODIN (it's just a Security update), only change CSC to EUX, updqte OTA to XE9 and agin change CSC to INS. GPay works.

In XE7 most probably GPay also works because is same bootloader (as XDE) already fixed by Google.

P.S.

Other user confirms: XE7 is OK.
[Samsung Galaxy S23] bastoun19:
Thank you for your answers. I still have a question because yesterday I went back to EUX to do the june update but it was not proposed. So I went back to INS and the June update was proposed to me. I would like to point out that I was in XDE and therefore I still am.
[Samsung Galaxy S23] ChoSmile:
OTA (On The Air) Update is small package that contains differences between current and next firmwares.

For S23 series firmwares for INS and EUX CSC are:

INS	EUX
S918BXXS5CXE9
S918BXXS5CXE7
S918BXXU5CXE3
S918BXXS5CXDF
S918BXXS5CXDE
S918BXXU3CXD3
S918BXXS3CXD2	S918BXXS3CXD2
S918BXXU3CXCF	S918BXXU3CXCF
S918BXXS3BXBD	S918BXXS3BXBD
S918BXXS3BXAD	S918BXXS3BXAD
S918BXXS3BWL3	S918BXXS3BWL3
S918BXXS3BWKC	S918BXXS3BWKC
S918BXXS3BWK5
S918BXXU3BWJM	S918BXXU3BWJM
S918BXXS3AWIG
S918BXXS3AWI1
S918BXXU3AWH3
S918BXXS3AWF9
S918BXXU2AWF3
S918BXXS1AWD1	S918BXXS1AWD1
S918BXXU1AWC8	S918BXXU1AWC8
S918BXXS1AWBM	S918BXXS1AWBM
S918BXXU1AWBD	S918BXXU1AWBD
S918BXXU1AWA6	S918BXXU1AWA6

All firmware are MultiCSC, all of them have internally all CSC but not between all two of them are "OTA update" with changes.

So, if you change (switch) CSC when you are on WBM for exaample, you will contionue receive OTA updates because on both CSC channels are OTA firmmwa from WBM to WC8.

When you are on XDE (INS) and change CSC to EUX - there is NO XDE for EUX, so There will be no OTA update.

Going to INS again - OTA comes to XE7.

The way to move to other CSC channel and continue to have OTA updates - are both channels to have same firmware OR to flash FULL FIRMWARE with ODIN, for exmample XDF (EUX), so it will come XE3 and XE9.

If full firmware have 5 (five_ files: BL_, CP_, AP_, CSC_ and HOME_CSC_ )

ODIN flash with BL_, CP_, AP_ and CSC_ files are finish flash desired firware and makes reset (wipes everithing).

ODIN flash with BL_, CP_, AP_ and HOME_CSC_ files are finish flash desired firmware like UPDATE - all data stay.

Phone accept flash files with same bootloader version or bigger.

Bootloader verion (1...9,A...Z) is the 5th digit/letter (from right to left), you and see it start from 1 and now is 5.

First several leters/figits are model and region.

Next S (security only) or U (update: security and features) - type of update.

Bootloader

Android OS or UI version: start from A, now is C - so 3rd Major update. (Z is BETA test version).

Year W is 2023, X is 2024, Y will be 2025

Month A - January ... L - December, (M is month 13, pre-release)

Last one is compication inside month (1...9,A...Z), there are internal firmwares that was not pass something to become public. For example : XE3 and XE9 are 2024, May updates but 1,2,4,5,6,7 and 8 was internal tests for EUX channel.
[Samsung Galaxy S23] 7alvoo:
Dear ChoSmile,

I do not want to abuse your patience, but I have a few questions:

Can I make my EUX device fully flash to ILO firm ?

And then I will not only get the ILO CSC function but also the future updates for the ILO line ?

Obviously, when switching, you have to wait for the ILO firm version to be higher so it won't go from XE9 to XE7, but from XE3 to XE7 ok ?

If my EUX device's CSC is already set to ILO, do I need to switch back to EUX before flashing the full ILO firm?

And Is it also possible to switch completely without losing data using home CSC ?

Thank you for your patience!
[Samsung Galaxy S23] ChoSmile:
At the beginning Samsung push same firmware versions for both (all) CSCs of OXM MultiCSC.

Later separate channels and OTA updates are only from current to next firmware of active CSC. For S23* they become same at Android 14 but later separated again.

So, when versions are different you need to full flash with Odin (BL_, AP_, CP_ and HOME_CSC_ files) of desired CSC and switch it with SamFw (or Samkey) (Doesn't matter which is done first.) and OTA will work on next active CSC firmware release.

For 4th section [CSC] in Odin

- choosing CSC_ file will reset phone at the end.

- choosing HOME_CSC_ just update it, no data loss.
[Samsung Galaxy S23] SupremeJaguar:
Hi @ChoSmile and everyone,

I was hoping for some clarification, as I have been reading but still some things are unclear.

I purchased S23 SM-S911B in the UK. Firmware is:

Version: S911BXXU5CXE3

CSC : S911BOXM5CXE3

SamFw provides this link when pulling info: https://samfw.com/firmware/SM-S911B/EUX

However for any of the firmwares on this page given, I receive this list of CSC/regions. Why is that the case?

does that mean these are the only ones which would receive OTAs if I switched CSC?

View attachment 6118218

Am I able to change the ROM completely by flashing?, to one which has a different PDA version, such as:

https://samfw.com/firmware/SM-S911B/SEK/S911BXXS5CXE7

The CSC list for this firmware is different (and better):

View attachment 6118219

The model number is the same for the device, so trying to understand the difference in firmwares better, and why these lists are different, along with what is and isn't safe.

I guess the biggest question is, if we can flash the full firmware from another region, and then never have to worry again, and receive OTA always? or is it still required to do some flashing/tweaking sometimes?

Thanks!
[Samsung Galaxy S23] ChoSmile:
You can change to any of these CSC.

The CSC with Call Recording feature enabled are:

INS, THL, XXV, ILO, SEK, ZTO

You can change CSC with SamFw

And because all of them are different from EUX, ypu need to flash also with Odin if you want OTA updates.

There is also one option XID CSC and changed is only with flash because it is the SingleCSC and it is changed automatically.

What are the differences (features, extras and disadvantages) of CSCs... read the tread.
[Samsung Galaxy S23] bastoun19:
Thanks a lot for all these explanations. So, to confirm: if I want to full flash EUX with Odin, I take the last firmware XE9, that's right? But, if i stay with INS and firmware XE7 i still have OTA update for INS (but not for EUX). right?

last thing: if I full flash with CSC_files (wipes everything) do i need remove ggogle and samsung accounst before? Thks again!
[Samsung Galaxy S23] ChoSmile:
No need to remove accounts

flash BL_, AP_, CP_, HOME_CSC_ just update (no data loss)

OR

flash BL_, AP_, CP_, CSC_ ends with reset

if flashed with reset (CSC_ file) - phone will require last Google account.
[Samsung Galaxy S23] bastoun19:
and does this remove esim profiles?
[Samsung Galaxy S23] ChoSmile:
NO DATA LOSS... LIKE OTA UPDATE
[Samsung Galaxy S23] Yaovic78:
Hello guys,

I have never changed CSCs before, and I have a SM-S916N which is Korean. I want to change it to another country to use Samsung wallet. I know it only supports Korean CSCs, but I'd still like to change it anyway. I just wanted to ask, is there possibly any CSC that would still support updates afterwards that isn't Korean? Best if it's a CSC from North America or China, as I have sim cards from those countries. Also, if I were to do it, are there any of you who have done the same before and what happens? Do you have updates? Are there any issues apart from updates? Thanks!
[Samsung Galaxy S23] ChoSmile:
No way to flash with firmware for different model (than N).

No CSC change allowed for N models.
[Samsung Galaxy S23] Yaovic78:
Hm, I see. I guess it's too bad, but I'm fine if I can't, although are there any workarounds for samsung wallet because it asks for a Korean sim card which I definitely don't have. Is there maybe like a bypass for the setup process of Samsung wallet or maybe a modded version of Samsung wallet of another region that will run on the Korean model? I've tried different regions of the app's apk and it has never seemed to like it and just crashes on opening. Thanks for the reply, by the way!
[Samsung Galaxy S23] ChoSmile:
Samsung Pay and later Samsung Wallet is pride of Samsung in their native country South Korea. So do you look in Galaxy Store (not Google Play Store) for Samsung Wallet. Unless you rooted - it must be there.

Samsung Wallet - Apps on Galaxy Store

Samsung Pay got even better. Meet Samsung Wallet! Samsung Pay is now part of Samsung Wallet. With Wallet, you get the features and benefits of Samsung Pay, plus Samsung Pass, digital home and car ...

galaxystore.samsung.com

No modded or alternative version of Samsung Wallet - it use KNOX to store securely data, so also KNOX must be 0x0 (if even once rooted - KNOX is irreversible tripped to 0x1).

Try get South Korean prepaid eSIM if this help to to initial set-up.

OR better

Just sell this "N" version and buy "U"/"U1" for US, "B" version for Europe/Asia, "0" for China (but may have some restrictions like Google services).
[Samsung Galaxy S23] gpap2004:
No special benefits. If skvalex is working for you , you don't need to change CSC
[Samsung Galaxy S23] NIKOSXRI:
I have ILO from israel in my S21ultra for 2 years.

Everything works including hd voice, ecg blood pressure, hiya spam detector, and call recording....Its the best.

Only thing is that when i switched to my new s23ultra to ILO from EUX i had the volte switch.

When i was in eux i had a switch for roaming.Maybe volte switch is not necessary in EUX?
[Samsung Galaxy S23] eddiedimitris:
i tried via samfw but it does not do anything...After i press adb menu then no drop menu appears....i wonder what i do wrong...

[Samsung Galaxy S23] NIKOSXRI:

Hey, can you please also check if the show network speed on status bar is available in ILO? It's under settings > Notifications > advanced settings

Thanks in advance!
[Samsung Galaxy S23] gpap2004:
No. There isn't such a setting. I never saw this setting, neither to initial EUX csc. Maybe is a carrier add on.
[Samsung Galaxy S23] Kelsios:
Thanks. I'm in EUX and don't have it. I've also noticed that even though you have voice over lte enabled in settings, it doesn't show up as VoLTE in your status bar. Have you hidden it in settings or it doesn't work?
[Samsung Galaxy S23] gpap2004:
Volte is showing in cosmote or wind. In Vodafone where I belong, there isn't volte in status bar. Only 4G or 5G says (when wifi symbol closes). There is not hidden in settings, also. These are Vodafone s settings

I have successfully changed CSC to THL from KSA with SamFW 4.0. without any hassle. Simple easy stems and self explanatory with this Version 4.0.
[Samsung Galaxy S23] eddiedimitris:
Finally I also managed to change csc through samfw... I was following the wrong guide. Finally I installed INS csc and I notice everything works perfectly. It has HD call and volte... On the other hand, for a while when I tried THL I didn't see that it has hd call.. Once I see and get the first Ota upgrade there everything will be perfect
[Samsung Galaxy S23] Kelsios:
I think that NPL has call recording enabled, as well as network speed indicator. Can someone on NPL please check?
[Samsung Galaxy S23] kuschelhase_13:
'm straight on NPL on it there are call recordings but no network speed display sry
[Samsung Galaxy S23] gpap2004:
Definitely. As these CSC are all part of the same OXM multi language rom , they will take the same updates (even in different time). If you f.e. change to XID (Indonesia) , XID is not part of same multi rom ,so no OTA updates .

To make it clearer, EUX was our initial csc.

Every phone comes to a region with an initial CSC , specifically for that region. You can change CSC for the one that is part of the rom (the rom with CSC and region EUX , has many other CSC for other regions, as INS, THL, ILO , SEC.

Take a look to the following screens hot, you can see some of the available CSC which you can use and have OTA updates!
[Samsung Galaxy S23] gpap2004:
Sorry , I don't know. I know about EUX and OXM multirom csc
[Samsung Galaxy S23] alex_72gr:
Does ILO support the watch functions and spay?
[Samsung Galaxy S23] gpap2004:
I changed to ILO. I confirm watch functions as blood pressure monitoring and ECG are working well. I don't know about SPay , as it is not supported by the banks of my country, so it is useless for me.

[Samsung Galaxy S23] gpap2004:
Oh ,yes!
[Samsung Galaxy S23] Samsunga:
Which one is best ?
[Samsung Galaxy S23] gpap2004:
You mean between s23 ,s23+ and s23ultra? If this is the question, the answer is according to your needs. F.e. s23 ultra is the best for me , but if you want a not so big phone and not care about 10x zoom photography, go for s23+.

If the question is which CSC , then the answer is ILO and SEK if you have galaxy smartwatch, otherwise INS is excellent at the same manner
[Samsung Galaxy S23] Samsunga:
XID is bad ?
[Samsung Galaxy S23] gpap2004:
No , not at all. XID is not part of multirom OXM , but is very good CSC.

[Samsung Galaxy S23] PFusion:
For S23 variant users, if you change your CSC doesn't change what bands/frequencies are available?

I read some YouTube comments about this

And several users reported that some bands where not available.

1.) Is this true?

2.) Will you still be able to receive over the air updates?
[Samsung Galaxy S23] gpap2004:
It is not true. If you change csc of a multi rom firmware, you have no band lost and you can receive OTA updates

[Samsung Galaxy S23] asc366:
Do they, like, on the same time? Right now, for Europe, it seems S23U has a new update, while my s23u on SEK doesn't get it yet. It that because of phased rollouts or because of my changed CSC?
[Samsung Galaxy S23] gpap2004:
You will get later than EUX . It is the role out in phases
[Samsung Galaxy S23] asc366:
OK, thanks. Any experiences into how much later? I wouldn't want to use SEK for call recording and whenever EUX gets an update, go back to EUX, upgrade, and go back to SEK just for call recording.

It's my first Samsung in a while (ex-OnePlus here) so I'm unaware how much SEK lags behind EUX in general (For, S22 or something)
[Samsung Galaxy S23] TODI1111:
Apart from one or two occasions, SEK csc always received the update a few days later. It also happened that he received it a week and a half later, but also that he received it earlier.
