Go to the service center & tell them to update to the latest software...
They will flash the latest indian version firmware

Will it suit for korean version snapdragon processor phone?

I checked with samsung service center just now. They said not possible. If we install indian OS on korean version phone, the phone will become dead. Is it true?

Ohh...
Can't say about that
Did you said them that you've Korean version S20 Ultra?😅

[Nasheer]

Yes. I said to them

My service provider shows KT phone.. will it change after installing Indian OS?

This could be tricky
You can flash Indian Csc from Odin/Smart Switch but there's always a chance for bricking your device

Anybody has done it before? Any problems occurred?
