Cannot find OEM Unlock for Samsung galaxy s21 + 5g

[whiggs2]

Last month, I decided that I wanted to try rooting my Samsung galaxy s21 + 5g (model name SM-g996u), and I got as far as unlocking the network before I hit a snag. In all of the tutorials I have looked at concerning how to root my device, they all keep saying that I need to OEM Unlock my phone under the developer settings. However, as the title of this post would indicate, that setting is not present in the development settings. I have just about lost my damn mind trying to find and enable this setting via online tutorials, and I keep coming across the same suggestions: configure date/time setting so that it is not automatically set, manually set the date back a couple of months, go to dev settings and disable auto-update system setting, disable 'Download updates automatically' setting in software update (this is the only step I was not able to follow because that setting appears to have been removed from more updated version), and restart the device. I even tried removing my sim card, resetting my phone, and retrying the previously outlined steps. Nothing has worked. Is there anyone out there that can help me with this? Any info would be great.

Is device leased from a carrier, e.g Verizon? AFAIK by default this phone has OEM Unlock option in Android's Developer Options.

[Android][UNSAMLOCK] Bootloader Unlock for Samsung US/Canada Devices

This thread is @svetius approved NOTE: The OneUI 3.1 bootloader (March 2021 security update and later) will bypass the unlock token, Do not update or bump your bootloader version. So If you ever take the update and you can downgrade go for it...

This device(all of the US models) doesn't have the OEM unlock option. As far as I know, these devices have to be unlocked via a paid service from a 3rd party.

Device has been paid off. It is also network unlocked as well. The device was originally leased from Tmobile. I am aware that the setting is supposed to be in developer settings. I am telling you, it is not showing up for me.

May I'm wrong but the fact that the client have covered the contract, doesn't mean that the carrier do that, if a special petition was not presented to them, then, they don't care about. If the device came with a firmware that came with that feature disabled, so it, also, ends its "normal" life with the same featured included (or not) in the firmware by default.

But you could make advantage from the network unlocked condition, switching to a different firmware it would be possible, and, the option may appear.

I have seen that suggestion mentioned before online, though I have not really found any good tutorials on how to go about doing that. Any suggestions?

This - The 'U' devices do not have OEM unlock by default.

This may be just a kind of starting point, to have in mind, but that need more research though, I did it in my GN8 but with your device, things may be different.
There are some things you have to check, in the download screen, KG has to be completed, not prenormal or checking, also search for the CSCs that are compatible for your device, this is one of the tutorial, kind of, that I followed https://www.getdroidtips.com/guide-...ocked-firmware-galaxy-note-8-sm-n950u-n950u1/
