For those of you out there luck enough to already have a BlackBerry Z30 in your hands, you can now download OS 10.2.0.1521. Although this one is labeled as 'leak', it's actually among one of the OS' that has been appearing on shipping versions of the BlackBerry Z30 in some regions. So it in a way, could be considered official as well. Consider it a back up autoloader that will help you reset your device should the need arise.
That said though, where it is still an autoloader file and not standard operating procedure for loading an OS onto your device, standard leak disclaimer caution is still advised so there's that. As always be sure to use caution when installing leaked software on your device.
