re-lock bootloader

HI everyone, sorry for my ugly english.
My question is simple: How can I lock again the bootloader in mi G8 RIO-L03? I´ve unlocked this for few changes, and i'll like re-lock.
Thanks for the aswers!

Using fastboot, enter the code: fastboot oem lock. Then your bootloader should be re-locked.

Try doing the following
Code:
fastboot oem lock begin
Now enter all the commands to flash stock firmware then
Code:
fastboot oem lock
So you should end up with something like this
Code:
fastboot oem lock begin
fastboot flash partition gpt.bin
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img_sparsechunk.0
fastboot flash system system.img_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
fastboot flash system system.img_sparsechunk.3
fastboot flash system system.img_sparsechunk.4
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
fastboot erase cache
fastboot erase userdata
fastboot oem lock
Be aware that you can still tell the bootloader has been previously unlocked as normally when you unlock the bootloader it blows a fuse which can never be replaced (I presume unless you replace the entire motherboard)

Okay I'll try that. Cheers

Doesn't work! Just says "still require signed boot.img"

And I presume you have flashed boot.img from an official firmware during the process
If so find another firmware or I don't know the answer

So does that mean i can't relock my bootloader!?

RIGHT! I've locked the bootloader but now everytime i boot it. It says "Your device has loaded a different operating system" it would be great if it didn't

it means you need a signed boot.img so if the one you are flashing during the process isnt signed find another
try this one

There's no fuse that goes they can't tell if its been unlocked its not Knox , its when u get the unlock code they no the devices serial number . If you hard brick they can't necessaly tell!

The issue is in the signed boot image. you see, you need the official motorola firmware to be able to lock the bootloader again as they only have the signed boot images. :/
Why are you trying to relock the bootloader btw?

Can I Relock Bootloader, After Regular And Critical Unlock?

I've been advised that I should use both the unlock and critical unlock command so that when I flash the system image it also updates my bootloader. But I want to relock it after so Google Pay and everything works. I don't want to root or anything else. Would I have to again enter two different commands to relock everything? What are the ADB commands?

The instructions are clear, to lock the bootloader you have to run only ONE command: fastboot flashing lock
Beware, you have to be 100% stock, without any modifications!

Question How to flash stock rom? I'm on arrowos 13, but my bootloader is somehow locked.

I'm currently on arrowos 13. I wanted to go back to stock rom. So I tried flashing the fastboot rom via Mi Flash Tool. I got an error saying my device is locked. So, I checked if my bootloader was locked by using this command on fastboot " fastboot getvar unlocked" . It says "no", which means my bootloader is locked. I don't know how that happened. I tried to unlock the bootloader with Mi unlock tool, but it fails at the verification step itself. I don't how to proceed from here. I'm stuck with arrowos now.

You can't install custom roms on bootloader locked device.
