Well, the fact that the thread is five years old does not mean that I have the same problem with the Kobo Glo HD that I received this afternoon.
I loaded the 253 books that are present on my Bookeen Opus, and while the Kobo digests them it stops at about 10% and completely bomb, resetting.
I smell a rat in one of the books I have loaded, but how do I debug which one is the culprit?
