[Solved] Relock bootloader Zuk Edge?

Hi,
When i received my Zuk Edge few months ago I unlocked the bootloader and flash a custom ROM. But it was buggy and i prefered to returned to the stock ROM.
So im now back in Stock ZUI Rom, no root, no custom recovery, no custom rom/firmware... The only thing remaining "unofficial" is the bootloader, which i "unlocked".
How can I lock the bootloader of the Zuk Edge ? (i mean relock it)
Cause i didn't find any post on that subject
Thank you all
I found the answer actually on ZUK Fans Forum.
You have just to :
/!\ Be on Stock ROM (ZUI Official) /!\ (otherwise, you'll brick the phone)
- Go to fastboot mode (adb reboot bootloader)
- Type this : fastboot -i 0x2b4c oem lock
Then the device will restart (it will be a bit long, no worries)
The bootloader status won't be unlocked unfortunately, but "relocked".
Hi,
but with "relocked" bootloader, OTA Updates are not able. I made same step/mistake and unlocked the bootloader with the aim to get OTA Updates, but now there is no way cause of the really bad description I followed... (
Is there any solution to lock the bootloader again? Maybe editing the 'unlock_bootloader.img'?
Sincerely yours

Locked bootloader,formatted,only fastboot

Hello,i have the Redmi Pro but it was with fake os from the vendor.So i tried to unlock the bootloader as xiaomi suggested.I thought i have unlocked it,in the test menu it said unlock so i went to the next step.Downloaded SP Flash Tool,downloaded the stable rom and tried to flash the rom.
There was a problem with the cust.img file so i downloaded the suggested one for the fix but now it says that the img is a mismatch.
With a locked bootloader i can not flash through fastboot because it says it is not allowed,so does the XiaoMiFlash application.
No,the fastboot oem unlock doesn't work.
What can i do now?
Thanks in advance!

Could I unlock bootloader, root with Magisk (no TWRP) then relock.

Dear guys, I don't like the warning boot screen after unlock bootloader but still want to root my Mate 9. So I need to know, is there any problem if I unlock bootloader, then install Magisk with fastboot (without TWRP), then I relock bootloader? Are there anyone tried?

The phone does not enter fastboot / bootloader mode

Hi everyone,
I am the owner of an A2017G, unlocked bootloader.
I tried them all, but all of them and I can't get into fastboot / bootloader mode.
Ihave flash rom via MIFLASH and AXON7 EDL TOOL using rom Nougat and Oreo, but the result is always the same !!!
Do you have any ideas to help me, perpetuate?
Thank you.
Use miflash and flash unlock bootloader image by Turkdev, even in oreo it will give you fastboot menu.
I did this 3 days ago to relock my bootloader
Use this tutorial:

The reason you lose your fastboot menu because you unlock BL with another image (using Axon 7 EDL tool perhaps), but if you do unlock with turkdev image in tutorial, your fastboot menu will stay there
