maybe this will help [RESTRICTIONS-REMOVED] Samsung Health Monitor - WearOS
[Samsung Galaxy S22 Ultra] ilpincio85:
Followed your "tutorial" and now, everything, works like a charm! Thank you

Which feature are you missing? for me it seems everything is ok.
[Samsung Galaxy S22 Ultra] efkosk:
"blood pressure" and "ECG"

Does it work for you? Maybe there's a problem with my watch, or my location, or both: -)
[Samsung Galaxy S22 Ultra] ilpincio85:
Tested just now.

Pressure i need to calibrate it before testing.
[Samsung Galaxy S22 Ultra] gpap2004:
I great thanks to @efskok!!! I changed my EUX CSC to SEK (Ukrainian) successfully with Samkey! No data wiped! Now I have native call recording. My advice to anyone who wants to give a try ,is to try it now with the initial firmware A7 with January update. Maybe it could be impossible to change the CSC in next updates and need to downgrade.
[Samsung Galaxy S22 Ultra] tomesiek:
Hi all.

Just got mine (30 min ago). Can confirm that trick with SEK CSC work fine. Got call recording option. Now just setup, copy all settings and files.

PS:

My ultra came without screen protector - strange, lucky for me got one before phone been delivered ;-)
[Samsung Galaxy S22 Ultra] gpap2004:
S22 series have no screen protector any more .. Unlike s21..
[Samsung Galaxy S22 Ultra] tomesiek:
Just because i managed to get call recording i can forgive them that. :)
[Samsung Galaxy S22 Ultra] ilpincio85:
I found now that I lost caller id and spam protection with SEK CSC.

It has simply disappeared from dialer settings.

How can I re-enable it? Maybe we need a different CSC in order to have call recorder and spam protection?
[Samsung Galaxy S22 Ultra] efkosk:
You're right, spam protection is gone.

Other CSCs need to be tested.

These CSCs should have call recording:

BKD, EGY, ILO, INS, LYS, NPL, SEK, SLK, TUN
[Samsung Galaxy S22 Ultra] rodrigofd:
Just completed the process, changing my CSC to ILO (Israel).

I can confirm that native call recording works, caller id and spam protection are still there, and no data was formatted :)

UPDATE: Samsung Health Monitor doesn't work (unavailable on your region) :(
[Samsung Galaxy S22 Ultra] behemot24:
SEK disabled Samsung Pay, can't open the app anymore. Can you please confirm if you can launch it on ILO?
[Samsung Galaxy S22 Ultra] rodrigofd:
Sadly it seems that it became unavailable now, with ILO. I get to the start screen, and right away a popup saying "Samsung Pay is not admitted on your phone" :(

In my case I'm fine with it since I use Google Pay, anyway.

Any particular reason you need S Pay instead?
[Samsung Galaxy S22 Ultra] ChoSmile:
All Android display languages (menus) and all writing languages (keyboards) are available/possible in any CSCs.

P. S.

You know that INS is part of SM-S908E model and if you change CSC of SM-S908B model to INS - there will no OTA (Over The Air) updates. You must install every firmware update manually via ODIN (AP, CP, BL, HOME_CSC). If you not understood what is written in previous sentence - highly recommend you change your SM-S908B CSC to SEK, where updates works (but no Samsung Pay). Google Pay works on all.
[Samsung Galaxy S22 Ultra] gpap2004:
This is true. Although you can download the EUX firmware and upgrade though ODIN (SEC CSC didn't change through ODIN) I will wait for SEK ota update. It is very common for Samsung not sending OTA updates early. Be patient my friends
[Samsung Galaxy S22 Ultra] saturn3000:
It seems that the update S908BXXU2AVEH released on June 3 for the EUX CSC had problems of excessive consumption for the battery, in fact on June 10 the new update EUX CSC S908BXXU2AVF1 was released.

Surely for SEK CSC we will have the S908BXXU2AVF1 release directly.
[Samsung Galaxy S22 Ultra] jelbo:
I'm on AVEH and changed CSC from EUX to SEK yesterday. I will get OTA updates just fine probably, right?
[Samsung Galaxy S22 Ultra] Kenkanekiei:
I spent some time reading through this thread and from what i understand the my SM-S908U1 which shows csc OYM XAA dont have any option to get INS csc? My phone was brought from US a gift and im using it in India. Is there anything i can do to use A firmware for my region along with changing the csc?
[Samsung Galaxy S22 Ultra] ashwinkmgowda:
Hi

I am also using a galaxy s22+ SM-S906U1 bought from usa, which is OYM XAA, also looking for a solution to change CSC and use call recording, native Samsung Pay and other features

Please let me know if there is any workaround
[Samsung Galaxy S22 Ultra] Kenkanekiei:
lets hope there is a way . i got samsung pay to work after using a US zip code but i get offers and promotions related to the US . are we missing out on any other features other than native call recording.
[Samsung Galaxy S22 Ultra] R3XNebular:
Thanks, I bought my S22 Ultra from Samsung Aus store SM-908E, changed it to INS with no issues. I was wondering does both INS and THL support Call Spam reporting?
[Samsung Galaxy S22 Ultra] gpap2004:
Right
[Samsung Galaxy S22 Ultra] ashwinkmgowda:
Has anyone with U1 version tried changing CSC to ATC?
[Samsung Galaxy S22 Ultra] caser2010:
Does it work whit the Samsung A52 5G?
[Samsung Galaxy S22 Ultra] gpap2004:
Probably yes
[Samsung Galaxy S22 Ultra] ashwinkmgowda:
Hi

So, I have SM-906U1_OYM_XAA

Can I flash the INS version on it?

I don't mind updating manually via Odin every time.

If yes, can you please suggest the firmware I need to use?
[Samsung Galaxy S22 Ultra] ChoSmile:
I'm not sure. Never have U, U1 or N model to test. For S22 SM-S90xB it allows to change CSC to INS (might be because INS was part of Exynos B model in previous S21, S22 series or there was an plan/opportunity to make B model in India also.)

You can try with Samkey.

There are 2 options about active CSC:

- The best: will become INS

- The worst: will stay same and 1 Samkey credit will be lost.

You can write here the result for other XDA users ;) (if you want of course)
[Samsung Galaxy S22 Ultra] caser2010:
Dosent work on the A52-5G :( . Tried the SEK and restartet the phone, but still nok Voice recording options, and the CSC havent changed :/
[Samsung Galaxy S22 Ultra] jelbo:
Did you follow all the instructions, disabling screen lock and having no SIM? I have a different phone though.
[Samsung Galaxy S22 Ultra] ChoSmile:
A52 do not have SEK CSC.

For А52 can be used Single CSC XID updated via ODIN (AP, BL, CP, HOME_CSC). 🆓
[Samsung Galaxy S22 Ultra] caser2010:
Okay :) Can you link for the CSC XID i should use whit odin? Does i need to install a new recovery before i can use odin? And should i just start the phone in bootmode?
[Samsung Galaxy S22 Ultra] ChoSmile:
Use Frija with your exact model: SM-A52?? and XID to download firmware.

Put phone in Download mode

ODIN 3.14.4 (or 3.14.1) set AP_, CP_, BL_ and HOME_CSC_ files (not CSC_) and update your phone.

(All data stays if you use HOME_CSC_, or wiped if CSC_ used. )

We are discussing only methods that keeps phone's KNOX to 0x0 and warranty is stay Valid, So, original recovery is not changed, bank apps works, Google Pay works, no root, no firmware mods.

(without /DS)
[Samsung Galaxy S22 Ultra] gpap2004:
Strange thing.. although SEK firmware is already uploaded to Sammobile, OTA update is not available (for a first time , because till now all OTA updates came normally). I know i was the first who said be patient, but ... Any other with the same concern?
[Samsung Galaxy S22 Ultra] caser2010:
Now i found it, but not sure where to find the PDA number?
[Samsung Galaxy S22 Ultra] saturn3000:
Also for me, SEK CSC, AVF1 is not yet available via OTA update.

However, even here https://doc.samsungmobile.com/SM-S908B/SEK/doc.html the AVF1 update is not yet available.
[Samsung Galaxy S22 Ultra] caser2010:
It failes
[Samsung Galaxy S22 Ultra] ChoSmile:
PDA not needed.

CSC you need is XID (not OXM)
[Samsung Galaxy S22 Ultra] caser2010:
Arh now it worked :) Thanks :)

So now i need to dl the file 6.6GB? I asume its my backup?

Where do i find the new CSC file so i can record calls? Total new in this, so thanks for answearing my "stupid" questions :)
[Samsung Galaxy S22 Ultra] ChoSmile:
Whole procedure are written many times (on forum and in internet).

https://gprivate.com/5zjil

This is NOT your backup.

This file is archive of whole phone firmware.

Inside are 5 files: filenames starting with BL_... , AP_... , CP_... , HOME_CSC_... and CSC_...

You need first four. Do not unzip last one CSC_...

Open ODIN and select BL, AP, CP, CSC buttons all and choose corresponding file.

Put phone in Download mode.

(Google it if you do not know what is this and how to.)

Connect phone to PC.

Press Start on ODIN.

Wait until successful reboot.

Now in Phone (green call) app's settings (three dots on topright corner) will have Recording settings.

Hello.

I changed my branded S22 from MEO to unbranded EUX through Samkey, but since then I'm not receiving OTA's... I'm still on AVDB... I asked Samkey support and they say it's not Samkey related... do you have any idea what could be?

I'm not alone in this and also created a thread about this situation: https://xdaforums.com/t/csc-change-through-samkey-no-otas.4454801/page-2#post-87019225

[Samsung Galaxy S22 Ultra] ionone:
Hi,

I did not received the latest SEK update through OTA.

But I manage to update it to the lastest firmware through Smart Switch (Official Samsung App). Download it on your phone and computer and it will find the latest SEK update.

Link to download it (Samsung official website) : https://www.samsung.com/apps/smart-switch/
[Samsung Galaxy S22 Ultra] tsilva30:
yeah, I know.

I got the AVDB from Smartswitch but this time i'm not getting any pop-up
[Samsung Galaxy S22 Ultra] saturn3000:
When I connect the phone to smart switch with USB C in Windows 11 PC smart switch shuts down...
[Samsung Galaxy S22 Ultra] gpap2004:
Finally I got the SEK update through Smart Switch and everything went great!
[Samsung Galaxy S22 Ultra] jelbo:
Nice. Not for me with my S22 though:
[Samsung Galaxy S22 Ultra] loipram:
I can confirm S908BXXU2AVF1 via OTA (SEK). strange that it is not in the release note..

I just tried to change CSC on my S8+ (SM-G955F). I entered INS code. Everything was looking great, but after all, my country on phone is still UK. And still no phone records :( can sameone expalain why it didnt worked ?
[Samsung Galaxy S22 Ultra] cosmin971:
Hi.did you manage to change DO2 to EUX?
[Samsung Galaxy S22 Ultra] gpap2004:
Me ? No. I changed EUX to SEK once and for ever.
[Samsung Galaxy S22 Ultra] tsilva30:
do you receive OTA's?
[Samsung Galaxy S22 Ultra] gpap2004:
Yes , I received ota updates regularly. Except the last one (SV1). But I update to the new firmware successful with Smart Switch , the official Samsung app . It's exynos version
[Samsung Galaxy S22 Ultra] tsilva30:
just asking this because so many people (like me) didn't get OTA's after changing CSC through Samkey. specially if you change from a carrier firmware to unbranded firmware (EUX)
[Samsung Galaxy S22 Ultra] gpap2004:
Maybe this will happen in changes from unbranded firmware or if you set a CSC f.e from snapdragon version to exynos (as we saw for INS csc)
[Samsung Galaxy S22 Ultra] Yuna:
that happens when you change your CSC to region where this model isn't sold.

For example:

changing EUX (OXM) to SEK with S906B - I will still get the updates, as S906B is sold in Ukraine.

however, if I change CSC to ILO (Israel), which for some reason is in CSC files for S906B model, I will not get OTA updates, since Israel's device is S906E.

Same goes with S906U and U1.

Has anyone tried changing CSC via SamFW FRP tool? I want to know it's will factory reset ot not?
[Samsung Galaxy S22 Ultra] carlitobahsoun:
will not wipe
[Samsung Galaxy S22 Ultra] Droidphilev:
I treid it, doesn't seem to work :(
[Samsung Galaxy S22 Ultra] Yuna:
It highly depends on the FW version and some other, yet unknown, factors.

Two devices on the same FW - one might change, other might not.

Doesn't depend on ADB, just modem rejecting commands.
[Samsung Galaxy S22 Ultra] saturn3000:
Have you set up an available CSC for your model code?

If yes, try this:

1. Click on Change CSC and wait for the procedure to finish

2. Once the procedure is finished, click again on Change CSC and wait again for the procedure to finish.

3. Click Reboot and select [ADB] System
[Samsung Galaxy S22 Ultra] Droidphilev:
Hi again,

Well.... right after i posted that it didn't work i tried again and this time it worked!

1. did 'ADB devices'

2. started the tool, filled in SEK and pressed the "Change CSC" which gave 2 'fails' and 2 'ok'.

3. disconnected the device and reboot. CSC was changed and recording works!

Tried to go back to EUX in the same. Worked without any problems!

Bye Samkey! :)
[Samsung Galaxy S22 Ultra] ningsp:
I change from THL to INS via Samfw FRP tool. Confirm it's work.

[Samsung Galaxy S22 Ultra] Droidphilev:

[Samsung Galaxy S22 Ultra] tsilva30:
That's not this case.

EUX it's sold in my country.

Portugal gets S90xB EUX for unbranded S22.

However no OTA's after unbrand the device from MEO to EUX. This is common to all users who do this change through Samkey from branded CSC to unbranded

[Samsung Galaxy S22 Ultra] SHeGaRDe:
hello everybody,

for the past 5 days I've tried every suggested solution here to change my phone CSC to XID or SEK double or triple times each. used samFW FRP, SamKEY and also the phone code method. nothing worked.

tried every single remark mentioned here like : turning off security on my phone, removing the sim cards, turning off eSim, changed the USB cables, used different PCs etc. nothing worked.

both SamKEY and SamFW FRP showed me that the operation successful but the CSC still not changed.

the only solution i didn't use is flashing New Indonesian XID ROM through Odin. and i don't want to do that yet because i don't want to go through the whole process of formatting and reinstalling all my apps and data etc.

my phone info is :

Galaxy S22 Ultra 512gb , SM-S908E/DS, OXM_XSG_12_0010, XSG/XSG, XSG/XSG/XSG

android security patch 1 June 2022.

any help is appreciated.

thank you.
[Samsung Galaxy S22 Ultra] nguyenlucky:
No, you can only change between TGY and BRI.

Middleeast or Euro CSC are not available for 9080
[Samsung Galaxy S22 Ultra] nguyenlucky:
XID and SEK will not work with your device. XID is not part of the OXM multiCSC (which your device has). SEK is not part of the S90xE model at all (it's in S90xB with Exynos).

If you want XID you can just install the full Indonesian firmware with Odin, for free.
[Samsung Galaxy S22 Ultra] nguyenlucky:
No you can't. US version cannot change CSC to non-US or flash any non-US firmware.

Stick with XAA, or flash U firmware if you want faster updates.
[Samsung Galaxy S22 Ultra] nguyenlucky:
Perhaps your current firmware version is not available for EUX. Manually flashing the latest EUX firmware via Odin may solve the problem.

I changed my CSC from KTC (a Korean carrier) to KOO (Korean unbranded) using Samkey on my G981N a while ago, and OTA worked as usual. No Korean bloatwares.
[Samsung Galaxy S22 Ultra] ningsp:
DS is mean Dual Sim.

Dual Sim now support in model S90xE and S90xB (Physical sim and Esim).
[Samsung Galaxy S22 Ultra] ChoSmile:
For your device SM-S908E 3 options:

- Change to INS (or XXV) via SamFW FRP (free)

OR

- Change to INS (or XXV) via Samkey (paid).

OR

Download via Frija firmware for SM-S908E XID CSC

Three are 5 files inside, you have to use only 4 of them.

Update (free) via ODIN 3.14.4 with BL_, AP_, CP_ and HOME_CSC_ files.

(Using HOME_CSC_ file in CSC section instead of CSC_ file will NOT reset your device. So, again, do not use CSC_... file!!!
[Samsung Galaxy S22 Ultra] SHeGaRDe:
thank you. appreciate the help.

i think i made the mistake of assuming that XID will work for every model :)

for now i changed to XXV and both call recorder and Samsung pay working :)
[Samsung Galaxy S22 Ultra] SHeGaRDe:
thank you. you saved me .. your answer (change to XXV) worked perfectly. i used SamFW FRP.

now both call recorder and Samsung pay working.

thank you again. and as contribute to the thread, i have extra SamKEY credits so any one in need for them just DM me.

Anyone with an Australian S22, does changing CSC to INS/XXV/XID... enable the second sim slot?

The Australian version doesn't have DS in model number but still has eSIM, two IMEIs and dual sim dual standby capabilities. It lacks the second slim slot though (seemingly disabled by software), unlike the DS model.
[Samsung Galaxy S22 Ultra] ChoSmile:
What is the EXACT LETTER(S) /DIGIT(S) (?) after S22 ( SM-S901? ), S22+ ( SM-S906? ), S22 Ultra ( SM-S908? ) ?

SM-S90xB - International/Europe

SM-S90xU - USA

SM-S90xU1 - USA unlocked

SM-S90xW - Canada

SM-S90xN - Korea)

SM-S90x0 - China/HK

SM-S90xE - Asia/Africa

/DS - Dual SIM

x = 1 (S22), 6 (S22+), 8 (S22 Ultra)

I did not hear for Australian version.

As I see in Samsung Australia store it is E model, so you can change via SamFW FRP or Samkey to any E CSC (INS, XXV, THL). Without XID, it can be switched only via ODIN XID firmware.
[Samsung Galaxy S22 Ultra] nguyenlucky:
It's the E version. I am fully aware that it can be changed to other E CSC (INS XXV XID whatever) using Samkey or SamFW or full Odin firmware. I just wonder if doing that will enable the SECOND PHYSICAL sim slot.

S22 Ultra I checked in JB HIFI Australia is SM-S908E, without DS (Vietnamese version is SM-S908E/DS with two physical SIMs, eSIM, two IMEIs)

Edit: One interesting detail, when I check firmware version using *#1234* in the same S908E device, it shows the model as S908E/DS as opposed to S908E in About phone. So I believe that it's still a DS model, just disabled via software.

I havne't bought the device yet so I cannot test.
[Samsung Galaxy S22 Ultra] nguyenlucky:
S90xE also covers Oceania countries (ANZ) and Latin America (Mexico, Brazil etc)
[Samsung Galaxy S22 Ultra] ChoSmile:
Except change to XID.

About second SIM - Just TRY. I'm not seeing single SIM S22 model if they have 2nd SIM pins on board. Or eSIM cgip inside (just inactivated).

The best option - it will be available hardware and working.

The unpleasant oltion - it will be shown in menus but not possible to used because of hardware lack.

Last option - it will still not available.

If you want - Share with us (others here) what happens and if CSC was changed and recording works 🙂
[Samsung Galaxy S22 Ultra] tsilva30:
I have the latest EUX software AVF1, previously I had AVEH they're all part of EUX and I did flash the latest EUX from Odin.

Maybe this only happens with most recent phones s21fe, z fold 3 and s22 because these cases are happening with these phones and newer.

SM-S90*B - no, OTA not works, but manual works via ODIN with any B firwaware (EUX for example)

not possible for other models SM-S90*U, SM-S90*U1, SM-S90*N, SM-S90*0 - can not be changes

SEK CSC

SM-S90*B - yes, OTA works

not possible for other SM-S90* models

SamFW yes free

Samkey yes paid
