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.

[UNIVERSAL ASUS GUIDE] Unlock the Bootloader of any asus device

So a quick thread here. Asus devices won't be unlocked by the common commands which are
Code:
Fastboot oem unlock
Fastboot oem unlock confirm
From now on, asus uses there own codes.
Here it is
Code:
Fastboot oem asus-go
Fastboot oem asus-go confirm
This is not a guide. If you use the old command it will return an error UNKNOWN COMMAND.
Thanks !

[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 Unlock Bootloader doesnt work

Hello,
today i got a Moto E20 for debugging my webservices. I habe to Unlock the Bootloader for that.
I enabled the Developer-Menu in Android and the oem_unlock and usb-debugging in the settings.
When i boot the device into fastboot all seems OK... i get a connection with adb and fastboot to the device.
But all "fastboot oem XXX" commands just reply
fastboot oem device_info
...
OKAY [ 0.000s ]
finished. total time: 0.000s
Click to expand...
Click to collapse
That is the default reply for
fastboot oem get_unlock_data
fastboot oem device_info
just with different timings...
Any suggestions?
Bootloader version is aruba-1bfa2a4-2021
SW-Version: motorola/aruba_reteu/aruba:11/RON31.266-20/63893
kind regards
Sven

you are in the fastbootd mode .. the correct mode would be in the bootloader mode (adb reboot bootloader) ..
unfortunately it still does not work - the relevant command does not seem to work (fastboot oem get_unlock_data) -
motorola via support says it can not be unlocked .. but i certainly dont believe that - the e40 for example can be ..
the reteu firmware might be limited ..

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
