I think I've come to the conclusion that neither of the Fontin fonts works on K3 (of course it's probably just me

). On both the hackless hack and the full hack, I am unable to open my content. With the full hack my home screen and menus show the font (and they look bad) but I cannot open any book after applying the font.
I've used this font on my K2 and 505 with no problems but just can't get it to work with K3. I had to a 4th factory reset.
