Unlocking the bootloader on a Vivo device is a specialized process, primarily because Vivo does not offer an official unlock tool or authorization site like some other manufacturers. While the "OEM unlocking" toggle exists in the settings of most Funtouch OS devices, it often serves as a prerequisite rather than a direct trigger for the unlock.
