OEM unlock not available for Samsung S9
OEM unlock not available for Samsung S9
Does "enable OEM unlock" fall outside the developer settings?
You reach out to Samsung requesting access to your purchased phone or explore XDA-Developers discussions. It seems @OhioYJ might be right—that your device could be locked, indicating you don’t fully own it despite the purchase.
You can explore options on XDA. I checked briefly, and it looked like a particular version might be rooted, though not unlocked—rooting usually needs specific firmware. It seems you're facing a challenge with that model. You might need a different device to unlock it. You could try flashing a different regional firmware, which is sometimes possible on certain devices. However, I suspect this isn't straightforward for your setup, as similar issues are likely discussed in the community threads. It wasn't mentioned anywhere.
