So instead of step 4 in the instructions of post #1: if you can somehow extract libnickel.so.1.0.0 and libadobe.so into the patch_kobo_35 directory, then from that directory run:

mkdir -p ./usr/local/Kobo
./tools/patch32lsb-Darwin -p 3.5.0_source/libadobe.so.patch -i libadobe.so -o ./usr/local/Kobo/libadobe.so
./tools/patch32lsb-Darwin -p 3.5.0_source/libnickel.so.1.0.0.patch -i libnickel.so.1.0.0 -o ./usr/local/Kobo/libnickel.so.1.0.0
tar cvzf KoboRoot.tgz ./usr/local/Kobo/libadobe.so ./usr/local/Kobo/libnickel.so.1.0.0

Great!! Thanks GeoffR! it did worked for me now

Can I just drug it back into ./usr/local/Kobo folder and compress KoboRoot folder into zip archive and change .zip to .tgz? Will this work?

I'm not exactly sure what you mean, but I think the answer would be no, you can't create a valid .tgz archive just by renaming a .zip archive.

This one?

tar -pczf name_of_your_archive.tar.gz /path/to/directory

Sorry, I don't understand what you are asking.

Edit: If you mean to replace the files in the original KoboRoot.tgz with the patched ones, then that might work, but it is probably not a good idea. Better to create a new KoboRoot.tgz that contains just the patched files, because the device will then update much faster. You might need to apply the patch a number of times until you have it customised to your liking, and it will take much longer if you install the whole original KoboRoot.tgz each time.

Oh! Now I see! Do I need just to transfer on the device the new KoboRoot.tgz that was created with your script you gave me? Only that or manifest.md5sum and upgrade folder as well?

Just transfer the new KoboRoot.tgz containing the two patched files (assuming your device is already running firmware 3.5.0, if not, then upgrade first before patching it). After you eject the device, it will just unpack KoboRoot.tgz and overwrite the old files.

It worked super fine for me!! THANK you chrisridd and GeoffR! You're awesome guys, I appreciate that! Finally I've got Russian keyboard after 5 years! I just fixed my Kobo Touch broken display this week with one from Kindle! I'm back to my best eReader now
Cheers!

That function is quite different in 3.5.0, and I can't see any way to adapt the old patch.

Does the "Advanced" font setting (the weight/sharpness slider in particular) work with sideloaded fonts at all? I have enabled the patch, and I see the option; when I move the slider I see the effect in the preview panel, but it doesn't seem to have any effect in the book. (This is with v. 3.3.0, in Aura.)

Yes it does generally work with sideloaded fonts, although there may be some particular fonts it doesn't work with. Two reasons I can think that it might show correctly in the preview but not in the book:

1. You haven't pressed the "Apply" button before closing the advanced font dialogue.

2. The font showing in the book is not the font that you are have selected for adjustment. Try changing to a different font: if the font shown in the book doesn't change to the font you selected then the book has been created in a way that forces a certain font to be used rather than the one you selected. Only way to get around this is to edit the book's stylesheet so that the paragraph classes for the main text inherit the font set at the body level. (The font you select in the device's menu is applied at body level).

[Jellby]

Neither of those options applies. Changing the weight with one of the pre-loaded fonts works fine in the same book, which means that the font is not hardcoded. Strange... it looks like the same font in different books has different weights, but it may be a difference in size too. I'll try again after upgrading to 3.5.0 and rebooting. Maybe I should remove the books' settings too.

[GeoffR]

The sideloaded font I use for testing is Dark Courier: http://h10025.www1.hp.com/ewfrf/wc/s...reitem=lj611en

I think the patch `Fix page breaks bug` essential

I use to "disable" widows/orphans and avoid blank space at the bottom margin.

I tried to adapt to firmware 3.5.0
here:

# librmsdk.so.1.0.0 in firmware 3.5.0 (1ad1188b51)

<Patch>
patch_name = `Fix page breaks bug`
patch_enable = `yes`
replace_bytes = 2B87F6, E5 D0, E5 E7
#Alternative method
#replace_bytes = 2B87F6, E5 D0, 00 46
</Patch>

add file librmsdk.so.1.0.0.patch to folder /patch_kobo_35/3.5.0_source/

I hope it is useful.

Probably not that useful since the long paragraph bug was fixed in the version of the Adobe RMSDK used to build 3.5.0.

So far none of my test books showed that bug so I agree that it was fixed making the page break fix unneeded.

Without regard of the question whether this patch is useful, I would like to mention that in addition to

Linux users have also to add the concerned library to the FILES_TO_PATCH list in 3.5.0.sh:

FILES_TO_PATCH="./usr/local/Kobo/libnickel.so.1.0.0 ./usr/local/Kobo/libadobe.so ./usr/local/Kobo/librmsdk.so.1.0.0"
