Wanted to change my CSC from "SIN" to "INS"

[MaverickHuehuehue]

I recently purchased the S24 Ultra with a CSC code of SIN, which means I’m currently getting all the features available in Singapore.

From my research, I found that the device has a multi-CSC (OXM), and when I dial #272imei#, I can see a list of available CSC options to choose from. Since I live in India and use Samsung Pay and Call Recording, I’m considering selecting INS from the list and applying the change.

I understand that this process will reset my phone, which I’m fine with. However, I want to confirm whether this change is safe and won't brick my device before proceeding.

Not in my opinion if done properly.

I am planning to do with the same method that I have mentioned, so what steps do you think I should take care of?

[Wodehouse]

Take a full backup. Keep the phone fully charged. Ensure you have a stable network ,WiFi or cellular. WiFi preferred.

Not Change CSC via this menu

You need to use Samfw tool to change via computer

Oh, I thought using the default Samsung provided method would be safe!

Use SamFw tool change CSC, it is a 2 minute task and your data will not be erased. There are lots of tutorials available over Youtube, you can follow them.

Have you changed?

[MaverickHuehuehue]

No, I was waiting for someone's input who has already done it

You can watch system hacks video on YouTube; he had done it, and I saw comments where everyone said it was working fine. I also want to do it, but I don't want to take any risks.
