The list of LG smartphones for which bootloader unlocking is officially supported has been updated once again. This time, it's the LG V30 that's been added to the list - specifically, the H930 model that's on sale in some parts of Europe and the H930G Italy-only variant. If you aren't already aware, the bootloader unlocking process allows you to do things like running a custom ROM on your unit. But keep in mind that it voids your device's warranty as well.
