To my knowledge, to relock the bootloader we need to:
fastboot oem lock begin
<flash firmware>
fastboot oem lock
Is there any way to lock the bootloader without flashing the firmware?

hi guys, i've unlocked the bootloader with the dc-unlocker2client , And i want to go back to the original boot loader, i've tried to re flash the 137 and eve the 129 chinese rom but the annoying message on boot startup still exist..
so how to go back?
youre mixing up two things: the bootloader and the boot image
the former (bootloader) you unlock via fastboot and the unlock code that you read out via dc-unlocker. this is the reason why u receive the message at bootup and u can relock the bootloader via fastboot as well (fastboot oem relock XXXXXXXXX)
the latter is the boot image that u have to decrypt in order to be able to root properly and not be stuck in a boot loop. the boot.img is reflashed once u install a new stock firmware. but the bootloader lock state is untouched by this, thats why u manually have to relock it using fastboot!
cheers
thats weird.. i entered the fastboot mode
and opened the minimal adb - and wrote the command : fastboot oem relock XXXXXXXXX
the XXXX is my unlock code from the dc software i guess..
and its says : failed : stat not match
so.. how can i lock it again?

You don't need your unlock code to do this. Enter fastboot and issue the fallowing commands:
Fastboot oem lock
Or
Fastboot oem relock
Or
Fastboot flashing lock
Don't need to do all of these. Start with the first one.
I used this two command to unlock
fastboot flashing unlock
fastboot flashing unlocl_critical
So when i want to return to stock
flash stock rom via miflash flsh_all
Then type this
fastboot flashing lock_critical
fastboot flashing lock
fastboot oem lock
Is this the correct on?
please help me how to lock oem or bootloader to install ote firmware update on stock rom?
You use Fastboot command to achieve this:
Code:
fastboot devices
fastboot flashing lock <- or: fastboot oem lock
