How to Reverse Root?

[Guntzer]

I bought my Korean Note 9 as second hand without knowing it was already rooted. I already restarted the phone from the settings and even flashed it but it is still considered rooted. Is there another way?

If you flashed firmware coming from sammobile normally it undo the root .

In flashing the firmware make sure you see first the binary so that it will not fail.

Try to flash firmware, make sure it's the same region as when you bought it tho.
