I went from KitKat to lollipop and the font I've been using for the past five yrs won't work anymore. It is Diablo font. Other fonts work fine but Diablo just shows up as how the stock font is. I always changed the font with rom toolbox. I downloaded the font from somewhere else to see if something was wrong with my Diablo font ttf and it just appears as stock. Anyone have any thoughts on this?
