I spent hours surfing the internet looking for a way to Unlock Vivo Bootloader although the phone's Android version is a bit old and not knowing I have a tool that can unlock the phone's BL with a single click, the tool I used is Miracle Box 2.82, is common and almost every technician I know uses of it.
The phone I tried unlocking its bootloader is Vivo Y613F, I tried fastboot commands such as 'fastboot oem unlock, fastboot flashing unlock' etc.
