Okay.

Now if not Top Secret.


Country... better to know Sales Code aka CSC...

Example...
KOO is Korea... but seems Samsung Pay not work in Korea... :D :rolleyes:

Working country is for example... USA... with Sales Code aka CSC aka active CSC:
Code:
XAR

If you are from US... so good chain to increase your luck is:

Samsung Phone with Sales Code from US
+
Watch with CSC from US
+
Valid allowed supported Credit Cards for Spay...

Because this is also 1 funtastic phenomenon... not all Cards are samsung Pay enabled as it seems... :rolleyes:

If you wish to try CSC change... then Combination firmware and Stock Firmware allready leaked... but nobody tested yet... IMHO...

Only as info.

Best Regards

All I know is Samsung increased Security in Tizen 5.5... :rolleyes:

But this means NOT... old tricks not work... :D


In theory all leaked what """we""" need.

Combination FirmwareS to have Root access...

Stock Firmware to get back to """Normality"""

My suggestion is to check first if Reading and Backup work in CSA partition...

This could be done without play with Firmware...

Attempt to copy to PC:
Code:
sdb pull /csa/csc/csc-active-customer.inf

Code:
sdb pull /csa/imei/prodcode.dat

Attempt to show only:

Code:
sdb shell

Code:
cat /csa/csc/csc-active-customer.inf

Code:
cat /csa/imei/prodcode.dat

Try and see if this is working...

Maybe Samsung protected CSA again like in old Gear S2 times... :D

Best Regards

Thanks guys I manage to edit the CSC.



@roriii

Can you maybe explain what exact you wish... :eek:

Because IMHO SM-R840 is BT only device... this means netOdin files contains ALL CSC... also for USA:
Code:
XAR


Here I have uploaded few files...
https://forum.xda-developers.com/showpost.php?p=83275439&postcount=29

No idea if this is """official""" enough for you... because leaked files...

Only as info. ;)


Best Regards

I need S-pay on the GW3,
I know the previous generations of watches had S-pay pre-installed, Wonder why they left it out this time around. Hope someone soon figures a way out to change the CSC or even better Hope Samsung roles an update out with S-Pay installed

    Here is a transcription of the TechnoProz video, so all credits are going to TechnoProz.
    Please note that before applying this procedure you have to backup your phone as all data from phone will be erased.
    And please keep in mind that English is not my native language :).

    Change region - Samsung Galaxy Watch 3

    1) Prerequisites:
    a) The watch and laptop must be on the same WiFi network​
    b) Disables all Firewalls and all Antivirus programs on the laptop​
    c) The watch's battery must be fully charged so as not to have any surprises during the process​
    2) Check the existing model number on the watch:
    a) Settings / about watch / see now model number --- mine is SM-R840​

    3) Download from https://drive.google.com/drive/folders/1AuiQhGDRh1nqrMZZCJOH5PHAGReKpbgo the following:
    a) COMBINATION-FT55_R840XXU1ATG3.tar.md5.7z​
    c) Stock Firmware SMR840.rar​
    d) WiFi_Net_Odin.zip

    4) Unzip “COMBINATION-FT55_R840XXU1ATG3.tar.md5.7z” and get the file:
    a) COMBINATION-FT55_R840XXU1ATG3.tar.md5​
    b) Put the above file in a folder called “COMBINATION-FT55_R840XXU1ATG3.tar.md5”​

    5) Unzip “SDBstarterKidv1.zip” and get the following files:
    a) Guidelines_on_Connecting_GearS2_device_using_WiFi.pdf​
    b) Guidelines_on_Connecting_GearS2_device_using_WiFi_151222.pdf​
    c) sdb_2.2.60_macos-64.zip
    d) sdb_2.2.60_ubuntu-32.zip
    e) sdb_2.2.60_ubuntu-64.zip
    f) sdb_2.2.60_windows-32.zip
    g) sdb_2.2.60_windows-64.zip
    h) put all these files in a folder called “SDBstarterKidv1”​

    6) Unzip the "sdb" file corresponding to the laptop's operating system, I will unzip the "windows-64" archive, and get the executable along with some related files:
    a) Install.bat​
    b) We put these files in a subfolder with the name of the operating system chosen, for me "Windows 64"​

    7) Unzip "Stock Firmware SMR840.rar", there are 3 ".7z" files that we unzip and get 3 files:
    a) AP_R840XXU1ATF3_usr.tar.md5​
    b) BL_R840XXU1ATF3_usr.tar.md5​
    c) CSC_OXA_R840OXA1ATF3_usr.tar.md5​
    d) Put the files in a folder called "Stock Firmware SMR840"​

    8) Unzip “WiFi_Net_Odin.zip” and get the executable together with some related files:
    a) NetOdin3.exe​
    b) Put the files in a folder called "WiFi_Net_Odin"​

    9) Make the following changes to the watch:
    a) Settings / about watch / software / click quickly many times on "Software version" until the message "Developer mode tuned on" appears​
    b) We take a step back and choose "Debugging mode" and go to "On", Debugging mode on "​
    c) Press the two buttons simultaneously, the first one at the bottom, and hold down the buttons until “Select REBOOT Mode” appears.​
    d) Select “Download (Wireless)” using the “power” button at the bottom.​
    e) Press and hold "power" until a star appears in the middle of the screen and the text "Wireless download, do not turn off target!!”​
    f) Double-click “power” to select “WPS mode”. Now the watch works as a hot-spot​
    g) We now search the laptop for available wireless networks and select RM-840 and connect it​
