Once you unlock with HTCDev you cannot fully relock it. i.e. it will says "Relocked" instead of Locked. HTC warranty are trick but according to the agreement you'll get warranty for hardware fault not caused by unlocking Bootloader.
What are my options? Should I just wait for the official firmware zip or can I just relock bootloader and then flash ota? Also, can I unlock a relocked bootloader? S-on btw
Yes you can unlock a relocked boot loader

I'm seeing comments all over the web that you don't need to unlock your bootloader to flash a recovery. Is that true and can anyone confirm this. I'd like to just flash a recovery on my device and make a stock backup all without unlocking the bootloader.
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

Hi I lost my phone but my phone is locked with samsung id. Just wondering if any one can install custom recovery and custom rom without unlocking or if bootloader can be unlocked using adb or fastboot?
