How to change S9/S9+ CSC (Only Same Model Number's CSC)
Hi I will tell you how to change S9/S9+ CSC simple.
You can change to the same Model Number's CSC.
You don't need a special UART Cable.
It's simple to changing using RealTerm or PuTTY with any Type-C cable.
(I recommend Samsung's bundle cable in the phone box.)
Install Smart Switch and RealTerm or PuTTY.
I will tell you using RealTerm.
And you will need SamFirm to download Stock Firmware.
1. Find Your Model's Combination File by yourself!
And Flash by Odin.
2. If your phone shows your Model Number after boot.
Run RealTerm and go to Port tab.
Set Baud to 230400 and Select Port to ssudmdm0000 or very similar name.
3. Go to Send tab.
Enter "AT" and click Send ASCII.
If you get a response like
+USB READY
BOOTING COMPLETED
AT
or
AT
or
OK
or
BOOTING COMPLETED
AT
Proceed to the next number.
If you didn't get a response click +CR and send again.
If you get a response like "ERROR" proceed to the next number.
Still if you didn't get a response check your phone status and cable status.
If everything is normal proceed to the next number.
If still you didn't get a response it mean's your phone or cable is not normal status.
4. Enter "AT+PRECONFG=1,0" and click Send ASCII.
You will get this response.
AT+PRECONFIG=1,0+PRECONFG:1,???
OK
??? is your current CSC.
5. Enter "AT+PRECONFG=2,???" and click Send ASCII.
Enter ??? you want to change to another CSC.
You will get this response.
AT+PRECONFG=2,???+PRECONFG:2,OK
OK
??? is your changed CSC.
6. Enter "AT+PRECONFG=1,0" and click Send ASCII.
You will get this response.
AT+PRECONFIG=1,0+PRECONFG:1,???
OK
??? is your changed, current CSC.
7. Flash Changed CSC's Stock Firmware.
Congratulations!
You changed CSC for free by yourself!
Special Thanks to "HD Voice"
(He finded this method even without having a S9/S9+. Just a normal Korean User LOL)
