Once you get the hang of the whole process, you'll be pleased, if not thrilled, with your Kobo device.

I did this successfully last night. It did in fact restore the book to the Kobo. And, as I mentioned earlier, there are two differences, one minor and one major. Minor: that changed the look of the cover in the My Books list on the device. The cover no longer fills the bounding box of the icon representing the book. That's sloppy but oh well.

Major: reloading the book that way has somehow changed its "relationship" with the Kobo, such that I can no longer use the device's software to set flush-left/ragged-right. I have no idea why. It's the only book on the device that "resists" the FL/RR formatting, and I do want that formatting option. In the days when I would edit ePubs manually to fix problems in them, fixing this involved extracting the .css files, getting rid of the hard-coded text-align:justify commands (which should not be in ebooks in the first place), then refreshing the .epub file with the updated .css. The Kobo's ability to set flush left/ragged right got me around that irritation. So the ADE solution giveth, and also taketh away.
