Hola. Como lograste activar Samsung pay en tu reloj? Soy de la ciudad de México, tengo un Samsung Galaxy Watch de 46mm modelo SM-R800 y un LG V35 US desbloqueado. Ya cambie el CSC el reloj venia configurado TTT-TRINIDAD y TOBAGO y lo cambie MXO-MEXICO, instale el plug-in de Samsung pay en el teléfono pero me sale un error (adjunto imagen). Pero no logro hacer que la app aparezca en el reloj

I don't think is necessary to have S Pay in your phone. I am in Mexico and I am using the Note 8 US unlocked version and I can't use Samsung Pay on my phone because of the ROM (I need the official Mexican one) but after changing the CSC of my watch I can use S Pay over the watch without any issue. However I had to install the S Pay app on the watch.

Why would you change it to Mexico? Here in Mexico there is no official support to S pay on the Watch. I change it to USA, I think is XAR or XXA and my S Pay is working great.
Porque lo cambiaste a México? Aqu

OK, so I change it to the United States (XAR-USA) and I can use it in Mexico without problems? I'm going to change the CSC and see if I get the app. Thank you

No problems at all, i am using HSBC and everytime I use my watch to pay the people looks at me like a hacker or something like that hehe. I dont know if all banks support S Pay, but HSBC does.
As soon you change the CSC and your watch reboots the SPay app will be available to download, in my case the Watch ask to install it.

Please share if you could change it and use S Pay.

It's silly that they do not activate the S Pay support in mexico in the watches if it's already in the phones, but hey.

Done, I'm ready. When I restored it, I opened the Plugin on the phone and finished installing the app on the clock. Thank you

I was able to add two cards banorte and hsbc. Now we just need to try. Doubt, in that I have to check that I have the banking terminal when I pay. You see that later they do not know what can be done that way

Hello friends,
Thanks very much for the topic.
I connected my German Galaxy Watch (SM-R805F) and oppened the CSC options in watch.
Unfortunatelly there wasn't any Brasilian CSC (ZTO, BTA,BTM,TMR).
Does anybody knows if is it possible to insert a not pre-configurated CSC?
Thank you very much.

I have the same issue (Brazil CSC not in the pre-configured list). Did you find the solution for change to a CSC that is not in the list?

Thanks!

Hello
I've been stuck for almost 4 days now and i tried everything i can do but i have no knowledge of how tizen nor how SDB works. so i downloaded the SDB and opened the windows x64 which i got on my pc and i started cmd in the folder and after i tried writing SDB shell i get error: target not found
error: target not found
error: target not found

C:\Users\saba\Downloads\jdk\data\tools>
If i try to ignore and connect i get
C:\Users\saba\Downloads\jdk\data\tools>sdb connect 192.168.1.73:26101
error: failed to connect to remote target '192.168.1.73'
i even tried killing and starting the server
C:\Users\saba\Downloads\jdk\data\tools>Sdb kill-server

C:\Users\saba\Downloads\jdk\data\tools>Sdb start-server
* Server is not running. Start it now on port 26099 *
* Server has started successfully *

C:\Users\saba\Downloads\jdk\data\tools>Sdb shell

Does this reset itself to default region if we get software update for the watch? then we have to do everything all over again?

Hi,

I have just got a GWA2 and there was no Samsung Pay app on it even though I bought it from Samsung Shop. So I was trying to run this to see if fixed the issue.

When I run launch_app csc-manager.csc-pre-configuration it says it was successfully launched but nothing appears on my watch. Does anyone know what I could try next?

C:\tizen-studio\tools>sdb shell
sh-3.2$ ls
apps_rw data media share
sh-3.2$ launch_app csc-manager.csc-pre-configuration
... successfully launched
sh-3.2$

No, I have been in contact with Samsung support but they are about as much use as a chocolate teapot. I have sent them log dumps off of the phone and they are investigating, i'll keep you posted when I hear back from them.

Just to say worked a treat on my grey import from eglobal . . galaxy watch running Tizen 4.0.0.4 . . change to BTU

Little addition to people having trouble.

As per previous posts make sure wifi is below channel 10 (you will need to log into your wifi router to change this setting . . didn't seem to connect until i did this) . . also double check your spelling etc

(note: also worked previously on my frontier)

    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.
    5
    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.
