Replace DEFAULT epub fonts! (PRS-505) - Page 2

sherman · 12-23-2009, 03:28 PM

Hey, can we also use this to control margins, font size, paragraph spacing etc?

Yes. Anything that is controllable by CSS and is supported by ADE is a fair game for this hack. You may need to use the !important modifier to override book's settings, though.

I may have failed to express myself, too, because what I wanted to say was that I tried messing with the PRS-505 internals, in order to make the Adobe Digital Edition program use a user CSS stylesheet, but I failed ; you succeeded, and for this I thank you.

My PRS is now configured with Caecilia as my default font for ePub, and that's great !

Moderators, maybe we could pin this thread, because it's IMHO one of the major discoveries in the PRS-505 history...

Cheers,
David.

I thought that might be the case.

Now if only the version of DE on the 505 would support text justification... Then I could completely replace LRF as my format of choice.

agreed, and pinned.

bravo to pepak for this hack.

now, it would be great if you mad hackers could discover the userstyle.css for the 600 and 700 !

The same hack I used should work for 600 and 700, IF we have an ability to flash them. If someone were to send me a current firmware image, I would replace it.

pepak · 12-24-2009, 02:28 AM

If someone wants to give it a try, here you have a modified ADE for Sony PRS-600: http://tmp.pepak.net/hack-epubfonts-...ebug_only!.zip

I extracted it from the hacked russian firmware (http://translate.google.com/translat...D12146&prev=_t) and did the same modification that worked for PRS-505.

Note: I don't know if it works. I don't even know how to flash it back to the reader. If it breaks your reader, I don't know how to flash the original firmware back.

pepak · 12-24-2009, 03:07 AM

And the same thing for PRS-300:
http://tmp.pepak.net/hack-epubfonts-...ebug_only!.zip

Extracted from russian firmware as well:
http://translate.googleusercontent.c...8lxEcMQeyc861g

Same cautionary note applies: I don't have a PRS-300 so I can't test the hack. It may not work at all, it may brick your reader, anything. Not recommended for anyone who doesn't have a lot of experience with flashing his reader.

pepak · 12-24-2009, 03:16 AM

And for PRS-700:
http://tmp.pepak.net/hack-epubfonts-...ebug_only!.zip

Again made from the russian source:
http://translate.googleusercontent.c...otIIeMYIxT-VBA

The same cautionary note applies.

pepak · 12-24-2009, 03:19 AM

If someone manages to modify their firmware with these hacks, I would appreciate it if they could write a guide on how they did it.

Alternately, someone who speaks russian could perhaps contact user boroda who created the original russian firmwares, asking him to create a non-russian firmware which would be exactly the same as the original firmware, only with my ADE hack included.

sherman · 12-28-2009, 02:43 PM

Well, yesterday I decided to try this out (and combining with the PRSCustomizer hacks including new LRF fonts) and it works perfectly!

It will be so nice to be able to change fonts whenever I wish without having to reflash the firmware.

Thanks Heaps pepak

pepak · 12-28-2009, 03:19 PM

You're welcome.

Too bad I can't find anyone with PRS-300/600/700 to try the other hacks :-(

Pepak,

I'm just not that familiar with cramfs. I tried to unpack the image on the Russian flasher so I could insert your altered file using cygwin, but kept getting a missing superblock error. If you want to give me some pointers in that area, I'm willing to give it a shot. I was planning to simply modify the russian image and use their install routine to flash my 600.

pepak · 12-30-2009, 02:05 AM

Well, that's the problem, really - as I don't have 300/600/700, I can't try it and then provide a proper guide.

I think it should be possible to extract just a flasher from those russian links I provided and then use the "build new image" - "flash image" method of Igorsk's flasher (rather than the "copy image from card" - "flash image" expected by the russian guides).

Updating your original firmware (with cramfs tools) will be difficult because the firmware is encrypted.

Pepak, I need to test whether this hack was correctly integrated into PRS+. Could you please send me sample epub & userStyle.css? (email to kartu3@gmail.com or any other way) All books I have are LRF.

PS
I've changed path filename, hope you don't mind. In prs+ it looks like:
/database/system/PRSPlus/epub/style.css ("///opt/prps/epub/style.css" in so file, /opt/prsp is a symlink)
