Those who are having issues communicating via AT, first try setting the ports via *#0808# to RNDIS+DM_Modem or RMNET+DM+Modem or ADB+DM+Modem, reselect the correct modem port in terminal, then send a couple of AT <enter>'s till you get an OK response. You may need to try all three settings in case it doesn't work.

Hi ,
Are you able to successfully change the CSC to INS ? If so can you please share the steps and links for files if any needed. I am struggling for the last 2 days with this issue. My Samsung Pay is tied with UK. I want to change this to India.

Just wanted to say thanks to the OP as I have managed to change mine and get call recording and s pay working.

On the same note I heard that google is rolling out native recording across android and will just put the onus on the user regarding complying with law locally etc. A good move if it actually happens as it's one the feature many people want and then we won't have to use the hack!!

3º. Flash Combination File
4º. Change CSC with realterm
5º. Flash Multi CSC Android 9 again
5º. Update last version with SmartSwitch (more Faster for me)

All went good, Mr.Januzi

    I performed this tutorial on my G965F just for proof that it works. I took screenshots for those who may be interested, and just to help you along the way while you're changing the CSC on your device.



    Let's start off by saying, I did NOT find this method, I simply used the guide from @applepay in his thread HERE.

    I've added screenshots and proof to show that this works, and to show you how to use RealTerm to change the CSC on your device.
    Now, the main purpose of this would be to help those who have region locked devices, however since I don't have one, I can't test this. This will also benefit those who want DBT for example, for quick OTA updates, but don't have a German SIM card to change the CSC using the normal method.

    My device is a local Pakistani model so the CSC was PAK/PAK,PAK/PAK. Just for proof, I tried changing it to NEE (Nordic Countries). Screenshots are given below.

    ---------------------------------------
    Step 1) Power off your device and make sure to back up all data, since this will require a factory reset. REMOVE your SIM card before proceeding further.

    Step 2) Boot into download mode, and flash the combination file for your device. I had a v2 combination file for S9+ already, so I flashed that.
    Download link for v2 combination file for G965F - AndroidFileHost
    Your device should look like this while booting:

    Step 3) Fire up RealTerm and connect your phone to your PC. Once booted into the combination file, it will say either SM-G965F or SM-G965F [DS] if it's a dual SIM device.
    Should look like this:

    https://imgbox.com/9ZdRS0BJ


    Step 4) Click the 'Port Tab' on RealTerm, for me it showed Port 8 = \ssudmdm0000, if this shows up for you, it means your device has been detected by RealTerm, then set the Baud rate to 230400
    Screenshot:
    https://imgbox.com/OpwRG4qD

    Step 5) Go to the 'Send' Tab on RealTerm, enter 'AT' and hit the 'Send ASCII' button, you'll get this as a reply:

    Code:
    USB READY
    BOOTING COMPLETE
    AT

    Screenshot:
    https://imgbox.com/1ky52t8k

    Step 6) Enter 'AT+PRECONFG=1,0' and hit 'Send ASCII' again, you should get your current CSC as a response, in my case it is PAK.
    Screenshot:
    https://imgbox.com/iZgiAkqg

    Step 7) To change your CSC to your desired CSC, use this command 'AT+PRECONFG=2,???', replace ??? with the CSC you want to install on your device. I chose NEE, so my command looked like this: AT+PRECONFG=2,NEE
    Screenshot:
    https://imgbox.com/yTAo0uGI

    Step 8) To confirm your changes have been applied, type this command to test the current CSC, 'AT+PRECONFG=1,0', your response will look like the message in the screenshot below:
    Screenshot:
    https://imgbox.com/u2LjnmZU

    Step 9) Go to SamFirm, type SM-G965F and download the latest firmware of the new CSC which you have applied. Flash in Odin with AP, BL, CP and CSC_OXM and your device will reboot. Since the CSC has been changed, first boot will take a little longer than usual.

    Here is my device with NEE CSC instead of PAK:

    Guys the combination file U7 for g965f is out today but still not free, maybe someone can share it here.
    You can grab it HERE

    Now I'm confused [emoji53] Doesn't the CSC have to be changed by following the process in the first post of this thread?
    That's only if you don't have the SIM card of the region you want to switch to, or if you want to change to another unbranded CSC.

    In the case above, that user wants to switch to a carrier CSC, so the combination file method is not required.

    I mean, this method of changing CSC using realterm will work also for S10+ or not? by the way, I owned S10 plus (SM-G975U1)
    No it will not work fo the S10 series.

    Combination ROMs can't be flashed on S10 without special permission from Samsung.

    Great guide!
    It helped me a lot.

    One small addition : on my Note 9, when i started RealTerm, after flashing combination, RealTerm detected the port, but no command was being sent. I have digged a bit the issue, and realised that after selecting the port, i go to Misc TAB in RealTerm and click on top left Setup, phone gets detected, and all went well from there.
    Please add this part to the guide, so it will help others!

    Thanks!
