Relocking bootloader means your device required to have everything stock, (recovery, system, oem, all partitions), otherwise relocking will fail.
On stock recovery/after relocking,
you can't install/flash custom stuff. You will have STOCK only...

How to go back to stock and relock the Bootloader?

Hello
i have to sell my device so i want to get it to stock again.
My current Setup:
Bootloader Unlocked, Stock Recovery, Rooted with Magisk, Stock ROM 9.0.0.283
What are the Steps to go Back to Stock and wipe everything?
Ive read that if the bootloader relock again it is not able to unlock the second time? Is this correct? I want to get the Unlock Code to the person who buy it but if its real, he cant use the code anymore..
anyway is it possible to do the job with the Stock E-Recovery in the current state of my phone? Without bootloader Relocked? Or is it necessary to relock the bootloader again?
Thank you very much

Ask the buyer if they want it locked. Personally it wouldn't be worth my time if it couldn't be unlocked again. Better to check first..
If you want to lock (not relock) bl justdownload your adequate firmware from androidhost.ru and flash fw using Usb-otg method.
You can unlock/lock your bl using unlock code anytime you want (provided you haven't changed your mainboard in the meantime).

I thought you wanted to go back to stock. I've already gave you solution to bring back all the way stock.
I m not sure if it's even possible to re-lock bootloader using fastboot when you're on pie.
Bootloader status re-locked still means your warranty is void.

Hey I've tried this otg method but without success
If I try it with the dload folder option and try to force flash the emui updater throws an error.
Even with the dialer code method.. same..

I've tried the Huawei suite on PC and phone in fastboot mode..same..massage this phone can't be reset or so..
What can I do next?

It won't relock and you'll get updates normally.

RE-LOCK BOOTLOADER Asus ROG Phone II

Hi, I'd like to re-lock the bootloader. I have performed all the steps to convert from CN to WW (also the fingerprint and themes). From the RAW flash 1908.21 I updated manually to 1910.35 and everything is fine. Can I re-lock the bootloader or should I do it immediately after the RAW flash? Because in the guide here on xda he says: ''
Relocking Bootloader
* Thanks to our respondent pd0200426 We can now safely re-lock the bootloader.
* WARNING: This needs to be done "ONLY" right after a Stock Rom Raw flash. Attempting to lock at any other condition might brick your device.

Question unlock boatloder

can i install eu xiaomi roms without unlockbootloader and if unlocked can lock it again
You can't install eu ROM (custom ROM) without unlocking bootloader. And if you use any other ROM then the initial one meant for your phone don't relock bootloader. Or also you will brick your phone.

thanks
