It's because you are entering the wrong command. "fastboot oem unlock" is used on nexus devices. The command you will have to use to unlock is this, keeping the unlock token you got from HTCDev in the same directory as the fastboot binary
Code:
fastboot flash unlock token Unlock_code.bin

you cannot lock bootloader after installing custom system as it wont detect the system.

Can't Lock bootloader or Remove Bootloader warning

Hi. I am trying to lock my bootloader and delete the warning of unlocked bootloader. When I try to do "fastboot flashing lock" it gives me "permission denied". I think because of "Oem Unlock". My device is Asus ZE620KL(Snapdragon)and I couldn't find anything about this. When I search only thing I could find is "how to enable on Galaxy devices". I am willing to remove only unlocked bootloader warning but "in /dev/block/bootdevice/by-name/" there is no logo file. I hoped I could at least open splash and look inside of it but I couldn't even open with any tool or extract. For any help thank you.

For real lock bootloader so you need flash STOCK ROM.
For unmessage in bootloader Try:
Code:
fastboot oem lock
This need good adb-fastboot tool & drivers. Depend of OS of your PC too.

"fastboot oem lock" gives "unkown command" error.
"fastboot flashing lock" gives "permission denied" error.
My adb-fastboot and usb drivers works well. I can do every other commends but not these.

Unlock OEM via ADB

Hi, so my Xiaomi MI A2 is kinda not working and I think that wiping cache partition might help but I can't access the recovery so I wanted to install TWRP. The thing is I have the boatloader locked, I have the USB depuration activated but not the OEM, so how can I unlock boatload or unlock OEM via fastboot?
Thanks

Relock the Bootloader?

I know asking this question at a very early point would be very foolish, I tried searching various places for the answer but didn't, can anyone from previous experience or with answer tell me how can the Bootloader be locked again?
Thanks in advance!
EDIT: Thanks to IDunnoLookatXDA The BL can be locked using
Code:
fastboot oem asus-lock

Nope, I've tried all the asus specific and default fastboot commands:
Code:
fastboot oem asus-back
fastboot oem asus-csc_lk
fastboot flashing lock
fastboot flashing lock_critical
fastboot oem lock
fastboot oem lock_critical
fastboot flash !frp-partition! default_key.bin
None of this worked

Holy SH1T that actually worked
for beginners oem is no command
To lock the bootloader (or remove the annoying prompt you get at startup)
Code:
fastboot oem asus-lock

This does not work for me. This is what I get from the cmd prompt:
C:\Users\uli13>fastboot oem asus-lock
...
FAILED (remote: Command not supported in default implementation)
finished. total time: 0.004s
Please help
I've sent the device back because of Display issues, and no longer own it.
But what I understood from your response and suggest you is:
Turn off the device and put it in fastboot mode, then issue the above command and it should work. Hope it helps

Question Bootloader

Hello, can I lock the xiaomi bootloader by fastboot using the command: fastboot oem lock?

Hi, I think so. But I recommend that you also install a stock rom before you lock the bootloader, because it may happen that you can't start your phone anymore and you have to bring it to a repair shop.
