Hello
I did a short tutorial on how to change csc on Gear S3 R760. (possible to work with other Gear S3 models)
I'm not an English speaker, so excuse my mistakes.
I'm not a developer, and this tutorial is not my merit. I found the informations here and here.

Do this at your own risk, I do not take any responsibility.

thanks to @adfree

I tested this tutorial in my Gear S3 Frontier R760, Tizen 3.0.0.2, Rom R760XXU2CRC3

I do not know if this tutorial works in any version of firmware but you can try.


1)Go to settings/about gear/ and activate "Debugging"

2)Go to settings/connetion/Wi-Fi/ and set to "always on" then connect to your preferred network.

3)Go to settings/connetion/Wi-Fi/Wi-Fi networks/your connected network/ and scroll down until
you find "IP Address" and save somewhere that address.

4) Download to your Desktop "sdb tool" from here and extract the arhive SDBstarterKidv1.zip,
in the extracted folder you will find more archives.
You have to extract sdb_2.2.60_windows-64.zip if you are using 64 bit Windows or sdb_2.2.60_windows-32.zip
if you are using 32 bit Windows. I will use in this tutorial the version for 64 bit Windows.

5)Navigate to: C:\Users\EMP83\Desktop\SDBstarterKidv1\sdb_2.2.60_windows-64\data\tools
and launch the command prompt here.

6)Enter 1 by 1 the following commands:

6a)
HTML:
sdb shell

after this command you will be prompted by windows firewall and you have to hit "Allow"

6b)
HTML:
sdb connect 192.168.1.73:26101

change 192.168.1.73 with ip address from your watch (the one you saved earlier from Wi-Fi settings).

after this command you will be prompted in your watch to allow a RSA Authorization Key( you must allow it)

6c)
HTML:
sdb shell

6d)
HTML:
launch_app csc-manager.csc-pre-configuration

after this command a list with all available csc should apear in your watch. Select the one that you whant.
I changed from United Emirates Arab CSC to France CSC.
after this step all your data will be deleted and the device reset to factory settings.

Command works fine for R765A... but lose your hope... it only shows ATT.

Thanks anyway... if we could at least inject other CSC codes...

Sorry, I don't understand.....
I can only find
SDBstarterKidv1.zip
DebuggingANDfindIP.7z
SDBconnectRTLv1.7z

But there is no file called "SDB tool" or something like that.... --> Do you mean SDBstarterKidv1.zip ? (and the sdb_2.2.60_windows-64.zip inside ?)

EDIT :
I have understand what happened for me. ...
I had no connection because of the windows firewall and not a missing "SDB tool" file or something else.

It works now, I had change my CSC without problem

@yan74s

You are able to unpack archiv files?

Unzip or unpack?
With 7Zip for instance... if you are Windows user...


Depend on your OS... if you want 64 bit or 32 bit sdb.exe...

If you search harder... you will find sdb.exe
Code:
sdb.exe

Best Regards

Thanks for your help, It was my firewall that gave me errors, and I though I need something called "SDB tool" to get the connexion.
(Even answering "yes" to the firewall didn't give me the connexion, I had to disable It)

:confused:
XEF is France if I remember correct...

No idea if XEF is Samsung Pay enabled...

Try XAR for US...


Best Regards

I live in France that's why I use XEF but, it's seems it's not really enabled, you're right....

My situation before :

Phone S7 edge : PHN firmware --> no pay
Gear : original CSC - > Pay works (1 payed one time in a shop)

1st try
Phone S7 edge : XEF firmware (and got Oreo) --> Pay enabled Card registered
Gear : original CSC - > Pay get launch on gear but not on phone (can't register a card)

2nd try
Phone S7 edge : XEF firmware --> Pay enabled Card registered
Gear : XEF CSC - > no pay

3rd try
Phone S7 edge : XEF firmware --> Pay enabled Card registered
Gear : BTU CSC - > pay launch but can't register my Card, need an UK billing adress. Not functionnal

I suppose If I try with the XAR will be the same : must register a US Card....

Maybe I must wait that both of methods (phone and gear) are available in France and not only the phone. But I did It with the original CSC and I don't remember what is was... :(

I have SFR csc on my Galaxy S9 Plus and it is Samsung Pay enabled. On my watch I have XEF csc and Samsung pay it is not yet enabled. On samsung site they say that Samsung Pay it is enabled for Samsung smartphones and soon will be for Samsung smart watches also. My Gear S3 originally came with csc of emirate arab united and it was Samsung Pay enabled but I only works with cards from that country.

I have this error

C:\Users\jhpis\Desktop\sdb\data\tools>launch_app csc-manager.csc-pre-configuration
'launch_app' is not recognized as an internal or external command,
operable program or batch file.

What I missed?. I run ansicon.exe not sdb.exe

    Whenever I open sdb.exe in terminal, I get the list of commands and "Process Completed" at the end and I cannot type anything. Can anyone please help me with what I am doing wrong?

    Did you find a solution? it happens the same to me...

    I already have modified my CSC and Pay functioning ...

    The one that opens and closes immediately the console when executing "sdb.exe" is normal, then you have to execute "ainsicon" and from there put the commands ...


    I hope it helps you.

    A greeting.

    That's normal - sdb.exe is just installing the tool. You then open a Command window and follow the instructions:

    1. The SDB starter kit in the link to the tool provided by @adfree contains several .zip versions of the tool - select the one for your system configuration, extract it, and save it in a folder you can easily find later. It also contains a connecting guide (.pdf) which although based on the S2 is useful. Double click the 'Install' file; a CMD window will flash and close.
    2. Back up your Gear S3, as it will automatically re-set with this method once you change the CSC code.
    3. Enable debugging on your S3. Go to: Settings - About Gear - Debugging.
    4. Turn off Bluetooth on your phone, and connect your S3 to wi-fi (not to the PC as an access point; just connect to the wi-fi your PC is connected to).
    5. Find the IP address your S3 is connected to. On the S3, go to: Settings - Connections - Wi-Fi - Wi-Fi Networks. Tap on the connected network name, and scroll to the IP address.
    6. Open a Command window (type 'CMD' in the Windows search bar). Navigate to the SDB Tools folder in your SDB folder.
    7. Connect to your Gear S3. Type: sdb connect [the IP address, without the brackets]:26101
    8. 'RSA Key Fingerprint' will appear on the Gear - tap accept.
    9. Once connected, type sdb shell.
    10. At the prompt, type launch_app csc-manager.csc-pre-configuration . The CSC code selector will appear on the Gear; scroll to the one you want and select it. The Gear will reset.
    11. Once your Gear resets, re-connect to Gear manager (you will need to re-pair your Gear, and it will prompt you to restore from backup etc.).
    12. You're done! Note that I struggled a bit with getting it to accept my credit card - I reset the SPay app from within the app and re-booted my phone as another user suggested and that seemed to work - but even then, it appears to validate cards based on the CSC code/country selected so I haven't yet succeeded in getting it to accept all the cards on the watch that I have on my phone - welcome any suggestions in that regard.

    This method is so easy once you go through the initial set up that I might play with other CSC codes to see if one gives me more access than another...might... ;)

    Sorry for the double post, but it woked for me.
    I just have to restart the watch (watch active, tizen 4) after debug.
