You would need to remove the KoboRoot.tgz and manifest.md5sum files and the upgrade directory.

You would not be back where you started if the firmware revision was changed. If you copy those files for a firmware version, do a factory reset, re-install that firmware version and then copy the files back, you will be back where you were before the factory reset.

As to why saving and restoring the files on the visible partition is not the same as a factory reset?

The internal storage has 3 partitions only one of which is exposed through the USB interface. One partition is used to boot the Linux OS while another stores the information needed to reset your Kobo to the state it was in when it came from the factory. This means a factory reset will revert the boot partition to the firmware installed when you took your Kobo out of it's box while the user partition structure is restored with no books loaded.

A couple of other items:

In addition to the three partitions, there is a chunk of free space which is used to store the device serial number and some other mystery information.

If you are using ADE to handle DRMed library books, you will want to save a copy of the .adobe-digital-editions directory. Copying the activation.xml file from your backup back into that directory on your Kobo will save you from having to re-activate your Kobo after a factory reset.
