[Samsung Galaxy Note 9 Guides, News, & Discussion] Ayman M.S.:
Finally the real deal.

Hello everyone,

I want to share my experience with you so that all of you can benefit as I did. For a long time I really wanted to be able to change the CSC on my Note 9 (N960F/DS, XSG, Exynos, Android 10, One UI 2.0) for the purpose of call recording. I was not able to do that for months, but I've recently came across the real FREE solution. It's a free tool (just released about 2 weeks back) that you can search for on google & youtube " ChangeCSC All Samsung Free Tool " . The nice about this tool is that it works with ANDROID 10, does not require ODIN and it will neither require root nor will it trip your knox while being totally free (as of now), BUT it will erase all your data (i.e. Factory reset) so beware to recall your google & samsung accounts' passwords to be able to bypass the normal FRP lock after the phone resets (for those who do not know what FRP lock is ; just make sure you know your account passwords, otherwise sign out of all you accounts before executing this method). You will find multiple youtube videos for it & multiple links for its download. This tool is by far the most convenient as it will show you everything upon execution (resembling the old code method of dialing *#272*IMEI# ) as it launches Samsung's builtin "Preconfig" interface so that you can choose which CSC you want. I will try to conclude the steps as detailed as I can:-

1. Use your PC to Download the compressed file of the tool. (the sites on which the file is uploaded are really annoying, try to be patient to complete the download).

2. Disable any antivirus or security app temporarily on your PC before extracting the compressed file. (I used winrar free version to extract it.)

3. Run the resulting exe file as administrator. (Very important)

4. Enable USB debugging on your phone. (Just google how to do that if you're unaware of it)

5. Connect your phone through wire to your PC and press the "Check" button at the top of the tool to make sure everything is OK.

6. Choose your android version (8/9/10) then press "Change CSC" button on the left side of the tool.

7. Your phone should prompt you an ADB-granting request. Allow it.

8. After allowing ADB access you will be directed on your phone to "Galaxy themes" store to apply a temporary theme. Apply it. (All Steps starting from current Step will be shown to you in a detailed screen on the tool on your PC , so don't worry).

9. After this you will find the builtin CSC change option shown as "Change Carrier" under your device's Legal information. Choose the right Android version of your device.

10. Choose your desired CSC & then Choose "Sales & network code change" option when prompted.

Congrats. Your device will now factory reset and change CSC as chosen. (I took my SIM cards out at this point, Not sure if that will be of any effect).

I would also like to say that I did not lose VOLTE nor 4G+. And pretty much every single aspect of the phone remained the same so far (did not try everything yet), BUT I Finally got the Builtin Samsung CALL RECORDING.

One last thing for those who are looking for the call recording feature, the CSC that I chose was THL (Firmwares that support call recording include, but are not limited to, Thailand "THL" & India "INS").

Update: After changing CSC I failed to receive OTA updates , even no updates were shown on smart switch when connected to PC , though several updates were released. However I managed to update my phone without loosing data or regional CSC via Odin by using CSC home option to keep my data (I downloaded all updates from sammobile and I opted for my original region firmware updates; XSG not THL, while everything kept the same i.e I did not lose THL CSC and the call recording feature.)

Hope that helps.
