Edit: Of course you will need to have the relevant RUU for your phone (unbranded is x.xx.401.x, branded is x.xx.PHONE_PROVIDERS_ID_NUMBER.x), which should be able to be found in THIS thread.
Flashing steps are:
1. boot into fastboot and connect to PC
2. flash stock recovery
3. relock bootloader: fastboot oem lock
4. run RUU from PC, phone will need to be in fastboot

fastboot relock, locks device

Hello Guys,
i have a redmi 5a and i made a rollback on rom from 10 to 9.
i had to unlock the bootloader and install previous verson of miui.
i could done that succesfully.
but i also installed twrp and root.
now i want to relock bootloader but when i do it via adb
not just the bootloader locks but the whole device too
and the phone does not start.
then i go back to fastboot and unlock the device with miflash unlock
and it works again but the bootloader is still open
what did i do wrong?

It's possible to relocked your device after rooting but relock the bootloader means locking the mod of your device, you'll lose your root. And again, if you need to root your device, you need to open the bootloader.

U cant relock the bootloader with custom recovery coz phone it doesnt start and maybe hard brick.always relock bootloader with stock recovery.also consider relocking,because u maybe cant unlock again until unofficial way found

Question Oneplus 9rt fastboot and recovery not working Oxygen os13 stable

Few days back i successfully rooted my 9rt then today i unroot my 9rt and download the oxygen os 13 stable via op updater app and installed it but every time i reboot my phone it show a msg your bootloader is unlocked,device is in orange state can't be trusted reboot in 5 seconds then os boot normally but i can't access the recovery and fastboot mode to relock the bootloader plz help.

Looks like fastboot is locked in version you currently use (is it F.11?). You can't lock bootloader before next version with unlocked fastboot will be installed. The only other option is to downgrade to Android 12, then relock and upgrade again, but you will need to wipe data.

Update-after enable usb debugging and using "adb reboot fastboot" command i can boot into recovery mode where wipe data,reboot ar showing and my pc showing fastboot devices in cmd should i use fastboot command to relock the bootloader or wait for the unlocked fastboot stock rom.. thanks

It is fastbootd mode. Unlock/relock commands don't work in this mode, but you may use it to flash previous version of rom (fastboot rom) with unlocked bootloader.
Another option is to use this official ROM for local update. Please note it will wipe data, backup is needed.

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.
