Oups!...I have "Invalid format" on main menu, and everything froze!
I played with different style.css
First I have just one style.css and it works as it should.
Then i put three different css
style1.css
style2.css
style3.css
And I saw them in PRS settings, I could choose one of them. But when I go to "continue reeding" on some ePub book I did not see difference, css was not applied. Then I connected reader with USB and i saw that I have 4 files in /database/system/PRSPlus/epub/
style.css
style1.css
style2.css
style3.css
So I concluded that I forgot to delete my style.css when I put those other three (style1.css, style2.css, style3.css), and then I deleted style.css and then there was only these three. And when I disconnected reader from USB then my style3.css was apllied and it works great. But when i changed to style1.css or style2.css in PRS settings there where not applied, and somehow it returned to default state, like there is no any style.css file.
Then I connected reader with USB and saw these three (style1.css, style2.css, style3.css). Then I created empty file style.css so I have four css files. Then I disconnected USB reader and have same situation with default ePub font, with no css applied. But when I connected reader there was no that empty style.css, it was deleted, I only have style1.css, style2.css, style3.css
And when I disconnected reader from USB then (and now) I have frozen PRS-505 with "Invalid format" at the bottom
Did I make this situation with that empty style.css while I have other three (style1.css, style2.css, style3.css)?
Any suggestion on how to fix this ""Invalid format" frozen reader?
That is the main question right now
Other question is: why did other style.css was not applied when I set them in PRS settings? I don't know how I manage to make it work that one time.
