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
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.

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.View attachment 5649749 View attachment 5649751

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.
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!!!

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.

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 :)

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.

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.

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.

S90xE also covers Oceania countries (ANZ) and Latin America (Mexico, Brazil etc)

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 🙂
 
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.
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.

I'm in the US and have an S22, model SM-S901U1 with XAA CSC. Looking to change to another CSC such as INS that would hopefully support Samsung pay. Would I still get OTA updates?

Hello, I've the similar situation, I want to change to INS. Just wanted to know if OTA updates would work fine after this, if I change using SamFW? Thanks

INS CSC, depends of EXACT model (last letter):
SM-S90*E - yes, OTA works
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

I've 908E so I should be good then. Also, as far as I've seen it is not resetting the device so the data should be intact however, I'd still take a backup.

Thanks alot for the detailed answer! Appreciate it.

I used to flash Indonesia firmware through ODIN and native call recording was perfect in my S21 ultra EUR version. Now ,in S22 ultra with EUX csc (SM-S908B) Im wondering if we can flash Indonesia CSC because I don't know if it is another firmware belonging to SM-S908E versions of s22 ultra.
it is not possible because they have different processors.
SM-S908B =Exynos 😭
SM-S908E = Snapdragon 🥳

    I change CSC only to have call recording!! I need to press button REC every call or I can set automatic auto record?
    In the phone application settings you can activate automatic recording for all phone calls.
    2
    I want to ask if it works the other way around if I want to go back and change the CSC from SEK to EUX ?
    Yes, it works. I already tried it. First EUX to SEK, then SEK to EUX, and now SEK csc.
    2
    I have a factory EUX and changed to SEK. It should work normally OTA for me, but Ukrainian, right?
    Yes , you have OTA Ukraine update. Usually, you have it just a few days after EUX update
    2
    Really true????? Nobody said it's only for Pixels phones!!!!!!! I immediatly change the CSC!!!!
    Oh, yes !! No beep , no messages!! You just have it to auto recording - if you like it- (through phone settings) and you never have to worry about!

    For SM-S908E (SnapDragon):
    XID is SingleCSC and do not exist in MultiCSC, so can not be changed/switched by Samkey.
    The only option to change CSC to XID is flashing with ODIN. If flash with files: BL_, AP_, CP_ and HOME_CSC_ - it will not reset (with CSC_ instead of HOME_CSC_ phone will be factory reset)
    XID:
    - have call record,
    - do not have Samsung Pay (it have SPay but it is an Infonesian custom version with their local banks only, can not be changed with international SPay)
    - do not have internal spam, but can be used Hiya app (from PlayStore for any CSC)


    These CSC are from MultyCSC - all CSC are inside the firmware - and can be switched/chaged via Samkey at the moment (methods with local SIM, modded theme, Dialer code are fixed and not work long time ago, combination firmware works but no available files for current bootloaders)

    INS (India) have call record, SPay and and spam
    XXV (Vietnam) have call record, SPay, no int.spam but Hiya work
    THL have call record, spam, but SPay discontinued last year
    ILO have call record, other not sure (less updated, not every month, Jewish extra security)

    All CSC installs have specific bloatware apps (some can not be uninstalled but can be disabled via PC with adb or some package disabler via phpne)

    INS is better choice for E model.

    ---

    For SM-S908B (Exynos):
    Only SEK (Ukraine) via Samkey have Call recording, no SPay, no spam, but Hiya works

    ---

    For SM-S908 U, U1, W, N, 0 (SnapDragon):
    No know/available CSCs with call recording

    Using Samkey to chage CSC to one that not exist inside the exact same (U, U1, W, N, or 0) region of MultiCSC - do nothing, just lose one Samkey credit and CSC stays same.

    Flashing U, U1, W, N, 0 device via ODIN with E firmware is NOT possible because different models (even all are SnapDragon CPUs).

    At the moment call recoring:
    S22 (SM-S901x), S22+ (SM-G906x) and S22 Ultra (SM-G908x)
    * is model 1, 6 or 8
    x is region (the region have several CSCs)

    SM-S90*B (europe) - Exynos - via Samkey (paid) to SEK, INS
    SM-S90*E (asia) - Snapdragon - via Samkey (paid) to XXV, THL, ILO (or via ODIN (free) flash to XID)
    SM-S90*U (us) - Snapdragon - no CSC with call recording
    SM-S90*U1 (us) - Snapdragon - no CSC with call recording
    SM-S90*W (canada) - Snapdragon - no CSC with call recording
    SM-S90*N (china) - Snapdragon - no CSC with call recording
    SM-S90*0 (korea) - Snapdragon - no CSC with call recording

    They write on the web that it is not supported, but it is not true. I risked it and it works! So S22u is my daily from today.

    1. Turn on the developer mod
    2. Enable usb debugging
    3. buy credit on samkey (on the web or ebay)
    4. Install SamKEY CodeReader
    5. connect the phone to the PC
    6. turn on samKEY, log in and change CSC.

    This operation didn't seem to reset my phone. But I can't guarantee it.


    screenshot of my CSC version:

    I would also like to recommend the "AutoSync" application, which automatically uploads all your recorded calls to Dropbox. It all works on the S22u.

    Thanks for your informative reply.

    So for me, my best option is to get Samkey credit and just do the simple Samkey procedure to change my CSC to INS (INDIA) ? Right?

    Do you or anyone know if INS (INDIA) CSC would caused any feature to be unusable? Like Google Pay? Samsung Health with Samsung Watch? And will INS CSC have bloatware apps? Like?

    And last noob question from me, does changing your phone CSC affect your phone BANDS / Frequency ?
    I am using INS (Not changed CSC but I am living in India)
    No carrier bloatware except one My Galaxy. All features like GPay,SPay,S Health,Spam Call, Call Recording are working fine
    My personal opinion about CSC changing
    1.For Non Rooted device - Go with SamKey
    2.For rooted users - Instead of changing CSC just modify your own CSC file and get desired features. OR use a ROM with preactivated features

    Wheeej, successfully changed to "SEK" on "EUX" and call recording is here!
