Can't unlock bootloader

I'm trying to unlock the bootloader of my Nexus 5x, because I want to downgrade to 6.1 after proximity sensor issues. I tried "fastboot oem unlock" and "fastboot flashing unlock", but it looks like the bootloader auto-locks after reboot, and so I can't flash anything.
Did this happen to someone?
Do you have "Secure boot- enable (no rpmb)" on fastboot screen?
This is my fastboot screen

You can't unlock bootloader because probably you have replacement emmc memory/motherboard without flashed rpmb partition. You can't do enything with that, but on this forum there is a topic, where someone wrote how to work around this problem.

Update your platform tools, make sure USB debugging is enabled, then try again.

[Q] Relock Bootloader

Hey guys, i have to send my Pixel C to repair so i want to lock my bootloader. My Problem is, that i cant enable OEM unlocking in the developer options because its grayed out saying that my bootloader is already unlocked. "fastboot flashing lock" and "fastboot oem lock" both give me the error "FAILED (remote: Enable OEM unlock is not set)".
Is there a workaround for this?
Thanks for your help!
I also have this issue.
Same thing here. I loaded LineageOS and have decided to go back to factory. I can't figure it out either. Here are my results.
fastboot flashing lock
FAILED (remote: Enable OEM unlock is not set)
finished. total time: 0.022s
fastboot flashing unlock
FAILED (remote: Device already unlocked)
finished. total time: 0.003s
fastboot flashing get_unlock_ability
(bootloader) 0
OKAY [ 0.020s]
finished. total time: 0.020s
Ok all, I finally figured it out.
I had to download factory image 6.0.1 (MXB48J) go thru the instructions to flash this image.
Started up in android went thru the min setup to get into Settings and Developer Options. Turn on USB debugging and the OEM Unocking.
adb reboot bootloader
flashboot flashing lock
Prompted me about wiping the device.
Everything is good.

Question No way to unlock bootloader?

I got a ROG phone 6 few days ago. But I found that after I used the official unlocker app, I cannot find OEM unlock option in Developer settings.
I tried 2 commands in bootloader:
Code:
(bootloader)
fastboot flashing unlock
FAILED (remote: 'permission denied')
fastboot: error: Command failed
get_unlock_ability: 0
OKAY [ 0.003s]
Finished. Total time: 0.004s
How can I enable it?
To unlock the bootloader, you have to use unlock app from the Asus homepage. That's the best way to do it. Relock could be done by CMD command.
I also cannot unlock my bootloader. When i use unlocking tool app my device just reboot

Question error unlocking bootloader "failed to get unlock data"

Hello, I am trying to unlock the bootloader of my moto g60 but I have a problem to get the bootloader data with the fastboot oem get_unlock_data command, every time I try it returns the following error
c:\platform-tools>fastboot oem get_unlock_data (bootloader) Failed to get unlock data. OK [0.008s] Finished. Total time: 0.008s
I have tried to restore the firmware with RSA, but it is still the same no matter how many times I try, I always get the same error, if anyone knows of a solution, or has had the same problem and has solved it, please explain to me what I can do.
