I changed from EUX to Israel. In Bulgaria its perfect. Call Recording, Caller ID, Spam Protection are working perfectly.

I noticed that the Fw tool showed failed to change, but actually csc eas changed

INS have all. SPay, DigiKey, Call rec, CallID/spam, no reset, no data loss, add the 3 numbers to block list:
+919560345888
+918424098931
+919176905802

I would like to change the CSC of my S22 Ultra (SM-S908B/DS) from EUX to INS but this one is not in the list of available.
I only have these:
BTB | BTE | EVR | MEO | MET | SFR | TSI | BOG | CAU | CPW | EUX | EUY | MOB | MOT | MSR | O2C | PLS | PRT | SEK | SER | SIM | SKZ | SWC | TIM | TOP | VIP | WWA | WWC | WWD
Can I force SamFWTool towards one not present like THL or INS?
Thank you for reply.

I'm on TEL CSC (Telstra Australia). Will VoLTE still work after CSC change to SEK?

Does anyone have experience of if VoLTE still works after a CSC change? This is critical for me as our 3G network shuts down next year.

I haven't tried SEK but ILO csc still let's me use VoLTE. You'll lose S-pay with that csc though.

On S22 Exynos series - models B - only SEK have Call Recording. (INS is part of S22 SnapDragon E models.)

    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.
    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 !!!

    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!

    Can you give me an easy and specific guide to do it? I've never done it this way before. Only with samkey. Have you installed Sek on the s23 ultra?
    Yes , I used samfw for first time in my s23 ultra. The procedure is very easy and safe. I tried INS but then I changed to SEK for the reasons I explained before.
    In short:
    1. You enable ADB in your phone
    2. You download samfw to your windows PC and run it.
    3. Connect your s23 ultra with the PC through a cable.
    4. Run samfw , and press Tab adb in the program (it is the third tab in the upper place of the app).
    5. You will see a pop up menu with all available XOM multi- csc .
    6. Choose and right in the appropriate box the one you want (INS ,SEK etc).
    7. Press "change csc"
    8. It will appear a prompt saying dial *#1234#* (or something like that ) while the screen of your phone is looking like being in check mode( like the one you have in Samsung Member app when you want to make a check for some function).
    9. That's it. In seconds you have your new scs without data wiped!

    Short representation of current latest firmware S918BXXU1AWBD

    FYI (for your information):
    S918 - model
    B - region (U or U1 - US, W - Canada, 0 or 8- China, N - South Korea, B - Europe, E - rest world (for S23* B merged with E)
    XX - free, or operator specific
    U - updated features (OR) S - security only
    1 - bootloader version (firmware can be updated/downgraded only to same or bigger bootloader version)
    A - Android/UI sequence version - starts from A, B, C, ... (Z - beta test)
    W - year (... U - 2021, V - 2022, W - 2023, X - 2024, ... )
    B - month (A - January, B - February, ... L - December)

    S23 Ultra (SM-S918B) INS csc - new OTA ...WBD
    Call rec, Call ID/spam, SPay - works.

    Do no update to S91*BXXS2AWEA
    The firmware is not signed by Google Play Protect - so phone become UNCERTIFIED and Google Pay stops, other SafetyNet dependent also.

    At the moment only THL CSC is pushed to ...WEA. Others (at the moment) are on WD1.

    TThe is nonoption to downgrade because this is first firmware with new 2 bootloader.

    Deleting, Unistalling, Clearing data, even Factory reset do NOT avoid uncertified status.

    (There is a chance for updating Play Protect but it's less likely before Samsung new firmware.)

    Current option for already updated to WEA:
    Just wait for new WEx (after A) or WFx firmware.
