The package also contains a directory called "upgrade". This contains the kernel and uboot images. These are hardware specific. Putting the wrong version of this on your device can be dangerous. The update mechanism in recent firmware should only install the correct files, but, older firmware didn't check and using the wrong package could brick the device.
If you do a factory reset and manually upgrade rather than letting the device do it, then be very careful. The factory reset version of the firmware is the most likely one to not handle this properly.
All the files in the upgrade package should be used together. While using just the "KoboRoot.tgz" is safe, there are sometimes changes that need changes in the kernel. There have been a couple of strange problems reported that were tracked down to the kernel not being updated properly.

Thanks for the info. So should I be able to do a manual upgrade from 3.12.1 to 3.16 without issue? On the Aura, of course.
