I was able to flash my reader successfully

But I still have some problem with the epub ccs customization. I was trying to set the font size, but I couldn't make it work.
Following koadic's advice, I have tried setting my font size in the html tag, but it doesn' t seem to have any affect at all. Perhaps my epub file has both the html tag and the body tag, and the device epub customization couldn't override the css in the file? Any suggestions on how to make it work?
Thanks!
