Unable to open .epub I've created in Calibre

If this isn't the problem, I've sometimes fixed a (similar) issue by converting to another format (like kepub, mobi, etc.) then re-converting back to epub.

If none of that works, it might be the particular file. Epub can be finicky handling graphics (which is what your entire ebook is.) A work-around would be to use an OCR app to convert the file to text.

Um, no. The problem was the horrible code that the scan produced. A span around each space sizing them slightly differently. And spans around each word. And the very large stylesheet. The time taken to render that on the device was seen as a hang and the device restarted itself. As I said, I tried a beautify in the calibre editor and after 20 minutes it hadn't come back. From memory, I left it running for over an our before I killed it.

try using calibre to convert eBook to ".txt" file then convert it back to ".epub" file.
