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)
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)

specially if you change from a carrier firmware to unbranded firmware (EUX)
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.

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.

I treid it, doesn't seem to work :(
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

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! :)

Has anyone tried to change CSC via Samfw FRP tool to a phone which CSC had previously been changed via Samkey?
Works?
 
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.

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

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.

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.

    You are right on this one and it depends on what everyone needs. I don't need call recording but I would like the integrated spam protection
    Sure, you are right but here we talk about how to have call recording so whoever is interested in this topic is because they want this feature.

    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

    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.

    Good evening everyone. For a few weeks now I have been the owner (I still haven't figured out if I'm happy or not) of a Samsung Galaxy S22 Ultra Exynos SM-S908B / DS. I live in Italy and I had enabled the call recorder on my previous Huawei P30 and I was very disappointed to discover that the S22 Ultra had it disabled (in the European version). Thanks this thread, using the SamFw FRP Tool 3.1 software and with the help of this tutorial in Italian I changed the CSC easily and in a few minutes. Free of charge (unlike using SamKEY). Now my CSC looks like this:

    Everything seems to be working fine. Except the anti-spam call service. Thank you all.

    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!
