Question Locked Bootloader? - Samsung Galaxy S21 Ultra

Hello,
I recently got a new S21 Ultra and I was trying to unlock the bootloader & flash stuff.
I haven't rooted phones for a few years, so I am unsure how much has changed. As far as I know, EU Exynos models have unlockable bootloaders, don't they? My S8 did back then.
As I noticed the OEM Unlock option Is missing from the dev. settings. Fastboot can't seem to detect the device either. If I go to DL mode, I see a line OEM Lock: on(L).
My build number is: G998BXXS6EWBB
One UI: 5.1
Is my BL completely locked or is there any hope that it can be unlocked?

Question about galaxy note 3 on AT&T

I have a note 3 from att (not connected to any network. it is carrier unlocked) is there a way to unlock my bootloader yet? i want to root with no problems like frp lock
The bootloader may not be locked if it is running an older rom, such as 4.2.
If the bootloader is locked, there's no way to unlock it.

I have 5.0

For non rooted device, OEM unlock is useful?

I have an unlocked (for use with any carrier) but branded 950F exynos 128GB that I don't plan to root, at the 10th day appeared the OEM unlock option, my question is:
If not rooting, is of any use to activate it?
I have searched about it, but I found mixed answers, some say it will trip knox, others that it will do nothing as it was already unlocked by carrier, or that it would help if bricked by failed update,
What would be more convenient ?

oem unlocking non persistent on g6

Hello I have a new Moto G6. I have enabled developer options and I've enabled OEM unlocking. But it doesn't seem to stay enabled between reboots? I just bought this yesterday. I'm trying to unlock the bootloader, but I can't unless OEM unlocking stays enabled. Am I missing something? I know there's currently no root for the G6, but still I think I should be able to unlock it, or am I mistaken?

That just allows the bootloader to be unlocked. You still would need to actually unlock it following the unlocking guide thread in the guides section

Yes I know this is not root, this is just unlocking the bootloader, yes I do have a key from motorola. But I can't do anything if OEM unlocking will not persist between reboots. I'm just trying to unlock the bootloader. And yes it is unlocked for sims.

I said nothing of root. Unless I am missing something from your original post, "Allow OEM unlocking" just allows the bootloader to be unlockable. After you tick it, reboot directly into fastboot mode (not back into android, that'll untick it again).
[GUIDE] Unlock Bootloader - This states after enabling OEM Unlock in settings (from within Android) to reboot into the bootloader (This guide says power off and then power back on while holding volume down, if you have debugging on you can just "adb reboot bootloader"). Rebooting back into Android with the bootloader still locked I believe does untick the OEM Unlock option.
ok thanks, I'll try again.
I have the XT 1925-6 US unlocked version. One of the first things I do with a new phone is to enable Developer Options and toggle OEM Unlock even though I may not Unlock the Bootloader right away.
The OEM Unlock toggle has stayed persistently on through numerous reboots with the Bootloader still locked.
Hmm.. Well I could have sworn I had seen what was described before, however it has been a while. I unlocked mine all in one go so I can't say. If it's supposed to stay on then I'd really be curious why it isn't for jloh

I tried it again and it worked, thanks. I guess I rebooted android at first. Thank you.

How do I see if my bootloader is unlocked?

Good evening. I bought a used mi 9 and was told the bootloader was unlocked but when I go to see it says the device is locked, the phone is secured. But if I go into developer options, the unlock bootloader was already checked (that was the first thing I checked) So I'm confused if it's unlocked or not. Thx

no oem unlock

Okay so basically i flashed WW_17.0210.2001.60_0 and i cant find OEM unlock in dev options
You cant unlock BL straight from fastboot, You either have to use Asus'es prioorietary app (which sends all Your device info to asus, theoritically voiding Your warranty), or the unofficial way - by basically flashing barebones sd855 BL, unlocking it, and then flashing ROG2 stock one back. For more info, there are proper threads regarding those matters.
