I want to update my Samsung S9 Sprint US but I don't have the option to unlock bootloader anywhere, not listed in developer options and download mode has bixby button to show barcode instead of hold vol up to unlock.

Hi all,
I did a test for an AOSP 10 rom on my Note 10+ N975F Exynos, I activated the OEM Unlock from the developers options, then I unlocked the boot loader from the download menu by long pressing the V+ key, then I want to go back to flash the stock rom but the OEM Unlock was grayed and in the download menu there is no v+ long press, I have only:
V up: Continue
V down: restart
Skey: show barcode
What should I do? or no hope and I will not be able to lock the BL?
Best Regards
So lately, I tried to unlock bootloader of my Samsung Galaxy M30 with One UI Core 2.0. As I had read in many guides that after successful unlock, the option of unlocking OEM will be grayed out. But when I enabled it, it asked for my device PIN, then Samsung account password and switched off automatically. After factory reset, it booted up but the OEM unlock option was still blue and togglable. It read Bootloader already unlocked!
I'm confused because there was no 'device lock' mode in download mode, no need to 'long press power up to unlock Bootloader in download mode' or 'no gray toggles'.
On Download Mode I could see "OEM lock: OFF" . Does it mean that my Bootloader is unlock.

You are bootloader unlocked. Check the guides on this forum, and also the TWRP thread.

The model is Samsung Galaxy S20 5G SM-G981B/DS. I want to carrier unlock it, would that be possible?
Bootloader and Carrier Lock are two seperate things...
Trying to root my note 10+, i've enabled the oem unlock and tried to follow a guide to unlock the bootloader. but when i try to press and hold the vol up key nothing happens and bootloader wont unlock, tried to just flash twrp but get blocked by OEM lock. any help appreciated.
did you find a solution? First you need to unlock this option from developer options.
I did a test rom on my Note 10+ N976N Exynos, I activated the OEM Unlock from the developers options, then I unlocked the boot loader from the download menu by long pressing the V+ key, then I want to go back to flash the stock rom but the OEM Unlock was grayed and in the download menu there is no v+ long press, I have only:
V up: Continue
V down: restart
Skey: show barcode
What should I do? or no hope and I will not be able to lock the BL?
Or can I update OTA with unlock bootloader?
Best Regards
Are you on a custom rom? If not :
1. enter fastboot mode
2. enter command like oem unlock but this time with oem lock or flash lock or just the opposite of unlock
DO NOT OTA UPDATE OVER UNLOCKED BOOTLOADER
Thank you for your help sir. But I risk to update my note10 plus on OTA with unlocked bootloader and I updated it successfully to latest version.
