hello

I have s23 ultra Sm-s918b european...this year as we have snapdragon chip i think we can easily change csc to INS without have problem with OTA updates in order to have call recording...is this right?What you think?

Thank you
[Samsung Galaxy S23] gpap2004:
Yes , it is right. BUT, if you owned a galaxy watch 4 or 5 you cannot have ECG and Blood pressure monitor. Otherwise, the watch is working. Also , if your carrier supports HD voice call , you will lose it.

My opinion is that SEK is more suitable for EUX users, than INS.

If you don't bother about the above I mentioned, you can go ahead INS.
[Samsung Galaxy S23] eddiedimitris:
First thank you very much for the answer...do you know has sammkey start to support csc change for s23 ultra?
[Samsung Galaxy S23] gpap2004:
Till the moment I write, it doesn't. But it is miles more easy to change CSC with SamFW app
[Samsung Galaxy S23] tomesiek:
hi.

Above that i think that Samsung Calendar app is "bit different" when you change to INS. In my personal opinion SEK or THL, are the best choice, those two CSC works form me since S9. THL up to S22ultra, now SEK, did not decided what to chose for s23Ultra yet, got time till Monday.
[Samsung Galaxy S23] s3axel:
Just changed from EUX to SEK without issues, SamFW worked like a charm - thanks to all here ;)

What I hoped for was that network speed indicator in status bar would also be enabled, but its not for SEK... Do you know whether this would work on INS?

Thanks, cheers,

Axel
[Samsung Galaxy S23] gpap2004:
I had EUX before changing to SEK and I didn't notice any network speed indicator. Maybe it is a carrier's function only
[Samsung Galaxy S23] s3axel:
Thanks, I know - it's not activated in EUX and apparently also not in SEK...it can be activated via CSC, though, if you are rooted.... But I want to try without root for the time being...

I'm wondering whether there is a CSC that has call recording and network speed activated and can be selected if you are on EUX-Multi-CSC....
[Samsung Galaxy S23] Kelsios:
Exactly what I would like to know as well.
[Samsung Galaxy S23] Samsunga:
Why you dont try with India rom ? https://samfw.com/firmware/SM-S911B/INS/S911BXXU1AWA6
[Samsung Galaxy S23] s3axel:
Thanks for the recommendation, does INS CSC have network speed indicator?...
[Samsung Galaxy S23] mahtabshuv:
Will i get ota updates with XXV unlike INS?
[Samsung Galaxy S23] nguyenlucky:

SEK working for call recorder.

[Samsung Galaxy S23] richardgsm:
i have samsung sm-f711u and sm-s901b is possible to change csc for auto call recoreding any one can guide me up please
[Samsung Galaxy S23] ChoSmile:
For Flip3 - no, it is US version.

For S22 - yes, change CSC to SEK with SamFw. (a lot of guides)
[Samsung Galaxy S23] InTheCage:
Call me an dyslexic idiot but I am missing a proper tutorial, all these bits and pieces don't work in my autistic head.

1. To be clear, with frp tool I dont need to flash any firmware, just change the code?

2. With snapdragon cpu u can change to any land code listed here?

3. Can't brick device with this and changing back is np?

going to try on m23 ( SM-M236B / DS ) - ( just for fun, backup phone )
[Samsung Galaxy S23] ChoSmile:
Yes x3

P.S.

CPU doesn't matter, same for Exynos or Smapdragon or Mediatek, so vailable CSCs are part of (inside) Mutiple CSCs firmware in Samsung firmware, the tool just switch "active one" between them (so featuures allowed/forbidden for "active csc" becomes available or hidden), unlimited time, or until Samsung forbid this method of switch in some feature firmware, who knows!
[Samsung Galaxy S23] kubavat9:
Can you please guide, how we will know when the CTS is Pass. because I am thinking to go with Option 2.

I am having MacBook. Is Samfw tool is available for Mac OS ?? I am not able to find it on their website.
[Samsung Galaxy S23] Anthosm:
Hey guys, I just noticed that I am on the OWO multicsc and want to jump onto the OXM. Flashing a different firmware won't trip knox in this case right? Also does your data get wiped or is it retained?
[Samsung Galaxy S23] ChoSmile:
Find a friend with Windows.
[Samsung Galaxy S23] ChoSmile:
If the model is same - you can flash with different MultiCSC. BL, AP, CP and HOME_CSC will not wipe data.

P.S.

BE SMART & SECURED - MAKE BACKUP OF IMPORTANT DATA IN ADVANCE!
[Samsung Galaxy S23] kubavat9:
OK. So SAmfw has no support for Mac.

based on your past experience, when will AHW3 INS will have Gpay working. means in generally what time do Samsung fixes this things??
[Samsung Galaxy S23] ChoSmile:
My guess: On next firmware... probably next month.
[Samsung Galaxy S23] kubavat9:
Thanks bro for the quick responses.
[Samsung Galaxy S23] kubavat9:
I am having the same singapore dual physical sim version handset and have changed CSC to INS sinces last 10 days and didn't received the august update in India on INS. So, I did the following:

1. I change to XXV and updated OTA will go to AWGJ.

2. Then change back again to INS to reenable features.

3. downloaded latest ODin and AWH3 of INS from Samfw website.

4. Flash with ODIN (BL, AP, CP, HOME_CSC) - so next time when new INS comes OTA will work.

In my case, AWH3 is CTS is Pass, so GPay is working on this AWH3.

Thank You ChoSmile for all the insight into this game. you were very helpful throughout.

Cheers.
[Samsung Galaxy S23] ChoSmile:
Samsung Pay
[Samsung Galaxy S23] kb5rir:
What is Spay? I want Call Recording, Caller ID and Call Screening.
[Samsung Galaxy S23] InTheCage:
It works on m23, INS didn't work for some reason, stayed on eux after reboot and no record options.

Think I put REK afterwards and works perfect.
[Samsung Galaxy S23] ChoSmile:
Most probably SEK :)
[Samsung Galaxy S23] nguyenlucky:
Because there's no INS for M236B.

[Samsung Galaxy S23] InTheCage:
Yes SEK.

How come there is no native app installed to play the recordings? Now I have to choose between vlc and total commander. Maybe I deleted the native app, same for mp3 files.

Recordings are m4a.
[Samsung Galaxy S23] ChoSmile:
The native app is Voice recorder from Galaxy Store.

[Samsung Galaxy S23] ChoSmile:
No, there is no CSCs in U, U1, W models and I don't know alternatives.
[Samsung Galaxy S23] jamaldeenmd:
Thanks.
[Samsung Galaxy S23] mirjabd:
Thanks a lot, Dear. I have got to proper answer.
[Samsung Galaxy S23] jpp604:
Just to add that i've just found out that in my region is not necessary to change CSC anymore.

For S23, using Brazil Retail (ZTO) now i have callrecording, hiya and spay from factory.

JP
[Samsung Galaxy S23] Anthosm:
My phone was imported from latin america so it has the multi-csc from that region and is on the Panama csc. It has call recording which is my priority but I am not sure about the rest. I can't find any list online about which csc from that region has what enabled. Does anyone know? (I think Panama might be missing Hiya and Spay but Brazil has all).
[Samsung Galaxy S23] xclub_101:
You can set the week to start on Monday in Settings at least in Samsung Calendar, Google Calendar and Outlook - that should cover most use cases ;)

That being said in August the ILO CSC was a HUGE plus - I got the August security patch weeks ago while on EUX there is no update as late as Monday 28th.
[Samsung Galaxy S23] sandeep_sp:
@ChoSmile bro .. i have got the one ui 6 beta OTA update.

You explained everything in detail.

THANKS A LOT. LOVE ❤ YOU BRO
[Samsung Galaxy S23] jamaldeenmd:
I have not

I have not flash yet, if i do can I receive OTA and can I use CSC instead of HOME CSC as I want clean install.

Thank you.
[Samsung Galaxy S23] nguyenlucky:
You sbould receive OTA, and you can use CSC file to wipe all data, good luck.
[Samsung Galaxy S23] jamaldeenmd:
Thank you sir.
[Samsung Galaxy S23] jamaldeenmd:
Sir, I don't understand regarding service provider having Thl or vvx. Please take a look at my attachments. Sorry I'm not expert in this. Thank you.
[Samsung Galaxy S23] ChoSmile:
Your phone's current active CSC is H3G (UK) and part pf OXM MultiCSC.

THL and XXV are part of different MultiCSC (OLM)

So if you want to change to THL or XXV, first need to download THL or XXV files (via Frija, samfw sie, sammobile site, other site)

There are 5 files inside: BL, AP, CP, CSC and HOME_CSC

Option 1

flash via ODIN (BL, AP, CP, HOME_CSC without data loss) and then to change active CSC via SamFw to THL or XXV. OTA updates will work.

Option 2

same as previous but use CSC file instead HOME_CSC file in ODIN (BL, AP, CP, CSC) - flash will finish with phone reset (like new fresh phone). Again use Samfw to change active CSC to XXV or THL. OTA updates will work also.
[Samsung Galaxy S23] jamaldeenmd:
Thank you. After flashing you mentioned I have to use Samfw tools to change active CSC toThl or xxv. Again please explain how to use the tool to change. I never done this before. I don't want to mess-up my phone currently my phone working perfectly. It's because of native call recorder only Thank you for your time.
[Samsung Galaxy S23] ChoSmile:
Really?!

Why does everyone need specially and personally made instructions?! It has been explained in this thread several times. A simple youtube search (samfw csc change) shows even a visual.

If you do not want to mess-up DO NOTHING !!!
[Samsung Galaxy S23] jamaldeenmd:
OK. I'll check YouTube as you mentioned.

Thank you for your time.
[Samsung Galaxy S23] corepda:
For anyone looking for instructions, it is pretty simply put down in the video below

My personal experience:

- Didnt realise it will be this simple. I only needed call recording.

- I used samfw for THL but realized Spay doesnt work, not that I use it but I suspect that may cause other issues too so I moved to INS. Call recording, Spay is working. Caller ID option is grayed out. Not sure if that is across the board for INS. I am in Australia so hopefully no other issues. Fingers crossed. Any other Australian users here that can report what works or doesnt work.

@ChoSmile great work supporting the community. @nguyenlucky thanks for the tip via PM.

Cheers guys.
[Samsung Galaxy S23] Anthosm:
I changed some time ago from the panama csc to brazil csc (zto). However I noticed recently that I haven't received any updates and that I am still on July security patch.

My version is

S918BXXS3AWF7

I checked on sammobile and there one newer version which is

S918BXXU3AWH7

That has the august security patch

When I check for updates and tells me that none is available and I am up to date.

I thought that simply changing csc would allow updates to carry on as normal. What gives?
[Samsung Galaxy S23] nguyenlucky:
According to samfw, for the AWF7 firmware, TPA (Panama) and ZTO (Brazil) have different CSC version. The former is AWF7, while the latter is AWFB. Hence you don't get OTA when changing CSC from TPA to ZTO while on Panama AWF7 firmware, because the CSC part is mismatched for ZTO.

1. If you want to OTA to the latest version, just flash the AWFB HOME_CSC file from ZTO AWF7 firmware.

2. Or you can full flash ZTO latest firmware with HOME_CSC.

Download Galaxy S23 Ultra SM-S918B (ZTO) S918BXXS3AWF7 in Samfw - Samsung firmware download

Either way, OTA will start working normally.
[Samsung Galaxy S23] Anthosm:
Thanks for your reply.

A few days ago I switched back to TPA amd got the latest update and then another a couple of days ago.

I noticed though that with latest update TPA and ZTO have the the same PDA/CSC S918BXXS3AWI3/S918BOWO3AWH9.

However I do see here that ZTO csc is not listed in the group

https://samfrew.com/download/Galaxy__S23__Ultra__/eim6/TPA/S918BXXS3AWI3/S918BOWO3AWH9

Do you think in this case OTA updates will be coming in if I switch again to ZTO with the CSC version now being the same or will updates still not come through?
[Samsung Galaxy S23] nguyenlucky:
For this AWI3 firmware, all PDA/CP/CSC are the same between ZTO and TPA, so switching back to ZTO will still preserve OTA. However, future updates may change that.

About TPA country group, it doesn't matter.
[Samsung Galaxy S23] Anthosm:
I think I get it now.

So it all ties down to the csc they shipped with. Which explains why when I changed to ZTO that it was listed as ZTO/ZTO, ZTO/TPA.

I ll probably just avoid the hassle of flashing the ZTO firmware and stay on TPA. It still has call recording, I just lose Hiya which is almost useless in the country I am from anyway.
[Samsung Galaxy S23] Beji-boy:
Hi, guys I have it Samsung Galaxy S23 Plus - [SM-S916B - dual sim] which CSC have enable call redord and callID protection HIYA ??

What it do cahnge CSC to other country? Is there some big problem or only allowed this function. I mean if there will be problem with updates and software :)
[Samsung Galaxy S23] ChoSmile:
I can not understand people that ask something (which is available in this thread because they are lazy to read), someone take their time to answers them (but because they are too lazy) they keep asking questions (already answered) and want someone else to explain personally and holding their hand, and next request will be (probably) please write me step by step how to change it.

Just do NOT do anything, forget about this!
[Samsung Galaxy S23] neogeo727:
INS still not certified yet after the latest update. I need Google Wallet to work, and avoid any data loss. Should I keep waiting for INS to be certified or should I just change my CSC to any other that keeps callid, callrec and Google Wallet?
[Samsung Galaxy S23] ChoSmile:
Option 1:

Download via Frija SM-S91xB csc: VIP

(x is 1 for S23, 6 for S23+ or 8 for S23 Ultra)

Flash via ODIN BL, AP, CP and HOME_CSC (NOT CSC file)

No data loss, still on INS, callrec works, callid works, SPay works, GPay works, no OTA (but can switch to EUX or VIP, OTA update, and then again switch to INS for every fw update) .

Option 2.

Same as 1 but download THL

Flash with Odin (BL, CP, AP, HOME_CSC)

Use SamFW and change to THL

No data loss, THL, callrec works, callID works, NO SPay, GPay works, OTA works

Option 3:

Same as 2 but ILO

No data loss, ILO, callrec works, callID works, NO SPay, GPay works, OTA works

Options 4:

Same as 2 but download XXV and flash

No data loss, XXV, callrec works, NO callid (can use Hiya as external app, popup), SPay works, GPay works, OTA works

Option 5

Wait for next INS update

P.S.

I'm on 1
[Samsung Galaxy S23] stiflerakos:
What about Galaxy Watch features ?
[Samsung Galaxy S23] ChoSmile:
As far as I know from other users ILO have SHM (Samsung Health Monitor) working for Samsung watches, callrec works, callid works, no spay, OTA works)
[Samsung Galaxy S23] Darkknight CSC:
I changed my S23 ultra CSC XSG to INS using SamFW tool . I got the call recording and Samsung pay. I was in September security patch (XSG) when I changed CSC to INS. In order to get regular software updates OTA do I need to flash the latest INS firmware which is October ( S918BXXS3AWIG) or should I flash September (S918BXXS3AWI1) ?
[Samsung Galaxy S23] ChoSmile:
XSG and INS have different files.

If you want OTA on INS, flash via ODIN (BL, AP, CP, HOME_CSC, no data loss).

OR

Otherwise change XSG, do OTA and again change to INS.
[Samsung Galaxy S23] Darkknight CSC:
Hi. I chnag

Thank you for reply . i want to flash via ODIN to get regular update in INS - CSC. currently I’m in INS CSC with security patch of September update which I got when I was CSC XSG. do I need to flash the latest INS firmware which is October ( S918BXXS3AWIG) or should I flash September S918BXXS3AWI1.?
[Samsung Galaxy S23] ChoSmile:
Latest INS to work later OTA on INS.
[Samsung Galaxy S23] Darkknight CSC:
Hi i

hi ChoSmiles

Thank you for the Help. As you suggested I have flashed my S23 ultra with latest INS October security update with Odin. Everything went smooth. Now software information shows in October security. Hopefully I should get future update via OTA. Thanks once Again for all your efforts.
[Samsung Galaxy S23] Darkknight CSC:
Hey, I have done the same thing on my S23 ultra. Flashed latest INS firmware with ODIN and everything working fine. Just wanted to know did you get security update via OTA?
[Samsung Galaxy S23] ChoSmile:
If flashed INS files and change via SamFw to INS (doesn't matter which of both was first) - you will have OTA update when new firmware is pushed for INS (security update, normal features update or major AndroidOS/OneUI update).
[Samsung Galaxy S23] supilota1183:
hi, I have a s23 ultra eux. I would need call recording and Samsung pay. which CSC do you recommend and also can I only do the csc change or do I also have to flash the files. for example if I put INS is it enough to just change csc or do I also have to flash the India files? Thank you all
[Samsung Galaxy S23] ChoSmile:
INS (India) or XXV (Vietnam) or ZTO (Brazil)

Better both Change via SamFw and Flash with Odin - to have OTA. (For EUX to ZTO you need first flash then SamFw.)

if you don't flash and still want OTA, you have to do for every new firmware release: switch to EUX, OTA update and the switch to desired again.
[Samsung Galaxy S23] supilota1183:
quindi se ho capito bene. per avere Samsung pay e la registrazione delle chiamate cambio il csc in quelli indicati da te con samfw tool. se voglio gli aggiornamenti via OTA ricambio il CSC in EUX, aggiorno e poi ricambio il CSC. ascolta e il codice SEK cosa ne pensi? un ultima domanda se posso meglio Samsung pay o Google Wallet ?

Thank you very much indeed

***Moderator Translation***

so if I understood correctly. to have Samsung pay and call recording I change the CSC to those indicated by you with samfw tool. if I want updates via OTA I change the CSC in EUX, I update and then I change the CSC. listen and the SEK code what do you think? one last question if I can choose Samsung Pay or Google Wallet better?
[Samsung Galaxy S23] V0latyle:

[Samsung Galaxy S23] supilota1183:
Thank you very much, I'm Italian and I use Google translator and I must have copied badly
[Samsung Galaxy S23] ChoSmile:
Option 1 (recommended):

Switch with SamFw to XXV

Download via Frija or via SamFw.com website SM-S908B and XXV and apply update (BL, AP, CP, HOME_CSC files) - there will be NO data loss.

Call Recording, SPay, GPay, OTA works

Option 2:

Switch with SamFw to XXV

On every new update, switch to EUX, do OTA update and switch again to XXV

Call Recording, SPay, GPay works, but OTA with two switches FOR EVERY UPDATE

* * *

SEK do NOT have SPay, do same as XXV - two options but without Samsung Pay

* * *

Google Pay is better - more banks, easy to use (just unlock and pay).

Samsung Pay requires additional activation.

(few banks supports SPay)

The only BIG ADVANTAGE of SPay was MST payment - payments to old magnetic stripe pos (before nfc), but it was active only in US/India and new devices no more include MST hardware (the latest was S20/Note20 series).

Currently I am in india and I want to use Call Recording, Samsung Pay(Samsung Wallet) and Caller ID

Thanks!
[Samsung Galaxy S23] ChoSmile:
There is a misunderstanding.

CSC is SWITCHED between available CSCs in firwaware, not changed to desired.

INS is in B model.

Your model is W.

There is no CSC in W, U, U1 models which have CallRec option.

Better sell your and buy B model in India.

Are you getting regular update via OTA ? or did you flash the phone with ODIN?
[Samsung Galaxy S23] saturn3000:
When I had S22 Ultra I changed the CSC from EUX to SEK and the OTAs worked fine. A friend of mine has it now and continues to receive OTA updates every month.

From what I read above, however, with S23 Ultra if I change CSC every time I have to go back to EUX to receive OTAs or flash the firmware of the new CSC, has there been a change on Samsung's part or have I not understood correctly?
