So far have made sure the ybook is fully charged re-downloaded a system file and reset. Now I get a miniture picture of start up page and plus three black dots and that is it.
At this point, either you've got so many new ebooks on the SD card or which you've added to the main memory of the Cybook that the Cybook is chugging through trying to create thumbnail images - or - you've still got a corrupted filesystem. If the former, let it sit and work its way through. If after several hours it still hasn't moved to the Library screen, then you've proved it's the latter issue.
The best fix for that is to download a copy of the latest firmware update from Cybook's store (the link on their blog takes you to the register/sign-in page) and follow their instructions to install it.
