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)

sdb shell

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

6b)

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)

sdb shell

6d)

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.

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

sdb.exe

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)

Now with XEF I don't have pay at all when I push the top button on the gear.....
[Samsung Gear S3] adfree:
:confused:

XEF is France if I remember correct...

No idea if XEF is Samsung Pay enabled...

Try XAR for US...

Best Regards
[Samsung Gear S3] yan74s:
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... :(
[Samsung Gear S3] EMP83:
Samsung pay will be soon released for Gear in France.

Not yet, soon!
[Samsung Gear S3] yan74s:
It's released in France now

Yesterday, I paid something with my gear. (my phone wasn't compatible because of an PHN rom)

This morning I updated my phone to XEF and Oreo : It gives me access to Samsung pay with my phone. But It has lost the function with the gear ..
[Samsung Gear S3] EMP83:
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.

For italian guys, set CSC = ITV, I've tried TIM CSC, but it doesn't allow to install Samsung Pay. After the factory reset check for Gear software update and install the latest version before configuring Samsung Pay.

Great guide, works like a charm, thank you.

Do anyone know the CSC for Brazil? ZTO is the appropriate one? Can I cross check in my Smartphone (S8)?

with the *#1234# I got:

CSC S8 - G950FOXM3CRG1

CSC S3 Gear - R7600XA2CRG3

I am willing to activate Samsung Pay on the S3 Gear Frontier (RM760)

Edit: Changed CSC using ZTO, Samsung Pay activated successfully.

Thanks a lot for the tutorial!

Any idea what im doing wrong? Do you think is my firewall?

Thanks
[Samsung Gear S3] AlbioB:
It's self explanatory, your target (Gear) is not reachable.

Did you put you Gear in debug mode?

Did you set wifi always on on your Gear?

Did you type the correct IP address of your Gear when you did "sdb connect"?

Did you allow the RSA key?

Redo all steps from 1 to 6b.

Temporarily disable your firewall too.

Also assure your router isn't blocking traffic between devices.
[Samsung Gear S3] MatHunter:
Thanks

Thank you for your response, i'll do it again following your instructions.

6a) <--- I thought this was the 1st step

HTML Code: sdb shell

6b) <--- So this is the 1st step really?

HTML Code: sdb connect 192.168.1.73:26101

Thank you.
[Samsung Gear S3] AlbioB:
Actually I don't remember, but you can safely try the step 6b. It just says to sdb to connect to your Gear.

Remember to change 192.168.1.73 with the IP address from your watch (the one you earlier found in Wi-Fi settings).

Hi,

I don't know why, but it seems a major part of the Gear S3 watches have the United Arab Emirates CSC.

I'm from Romania and the watch is from a local store but it had the UAE CSC and that bugged me up a little.

So, using the SDBstarterKidv1 and navigating to the "tools" folder in cmd and then running the commands one by one I managed to change the CSC of my Gear S3 Classic (this tutorial is for Gear S3 Frontier) successfully.

Need to mention that Tizen version in my watch is 3.0.0.2.

Thank you very much, I appreciate this guide

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?

Thanks for the input.

Let's see if I take a while and try to change the CSC to Spain to take advantage of Samsung Pay.

[Samsung Gear S3] jaco_ma:
Did you find a solution? it happens the same to me...
[Samsung Gear S3] jaco_ma:
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.
[Samsung Gear S3] jtOttawa:
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 [MENTION=1030585]adfree[/MENTION] 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... ;)

Thanks for the detailed explanation
[Samsung Gear S3] philr1983:

Changed my CSC from SEB to XAR, installed all the updates (there were two), and went straight back to SEB. Everything seems to be functioning.

P.s. Going to XAR allowed me to install Samsung Pay, now since I changed my CSC back to SEB its gone but I don't think that SPay would work anyway since my country is not supported officially.

Ok. So i modified csc from ITV to XAR

After rebooting and pairing i checked for updates.

I found first a 10Mb firmware (novermber update)

After that i found the new firmware (290 Mb).

Then i had new R760XXU2DSA1 firmware finally!

After all i modified again my csc from XAR to ITV.

Enjoy!
[Samsung Gear S3] TarekElsakka:
That message "sh-3.2$" means you're actually connected to the device and should skip to step (6d) in the OP.

I realized that the steps should 6b > 6c > 6d and just skip 6a.
