Font, ScreenSaver & USBNetwork Hacks for Kindle 2.x, 3.x & 4.x

[kuser]

@Niluje
In my Kindle keyboard jailbroken (010N) with fonts & SS hacks installed, I successfully updated firmware to v.3.4.
My (dumb) question is:
If I want to update Font & Screensaver hacks to new version, do I first uninstall previous hack?
I read the notes you wrote at 1.st post, but due to my poor english I dont understand correctly.

Regards

@kuser: Except for the jailbreak, you don't need to uninstall the old versions first. Just install the new one on top.

Hi Niluje,
thanks for Answer.
If I understand correctly:
I dont need to uninstall old jailbreak & Hacks.
On existing jailbreak installation I can Install new Hacks.

Thanks

@kuser: Nope, got it wrong.

You *need* to uninstall the jailbreak to upgrade it.
You *don't need* to uninstall any of the *other* hacks to upgrade them.

Ok very clear.
many thanks

!!! I installed your latest Jailbreak on my Kindle Keyboard 3.4 without first uninstalling the previous Jailbreak. It seems to have installed fine. Should I uninstall both and reinstall the latest version?

@montalex: If you were already using mine in the first place, and it wasn't a freakishly old version, you *should* be okay, but at the very least do a complete reboot, just in case.

If you were using Yifan's jailbreak, it might get a bit hairy. Try to uninstall one, reboot, uninstall the other, reboot, and then install the latest version.

... Another small update? Yay?! Fonts v5.4.N!

It's mostly a bit of cleanup after the fixes of v5.3.N...

* Removed the browser workaround, turns out it's unnecessary now that we're doing stuff properly .
* Added the bci_new FT override (bci built without FT_CONFIG_OPTION_OLD_INTERNALS). It might be more performant, but it might also be less compatible, especially on older devices/fw.
* Use the proper fontconfig config file in older K3 FW (<= 3.3).

That means that, if asked, the browser will now correctly use an FT override, like the rest of the system, thus saving a few hundred KB of RAM .

(And removing a somewhat nasty, most definitely hackish, piece of code that I'm surprised turned out to be so robust xD).

I also had to compress the packages in RAR, instead of ZIP, to get them under MR's 20MB attachment limit.

It was your jailbreak. I've always kept up-to-date with your stuff! Thanks very much for all you've done.

One question, though. I use custom Georgia 2 fonts. If I update the font hack, will I have to reinstall my fonts? I have my Kindle looking just as I want it now, with 10 point margins, bookcovers for screensavers, etc.

@montalex: The upgrade/install process will keep your custom settings/fonts/screensavers .

Hey, dear Mr. NiLuJe, I appreciate your efforts on kindle fonts hacks.
However, I met a problem on KF8 format books.
A same book that I transferred to mobi format and AZW3(KF8) format by calibre software, the mobi format can display the right font hack result (CJK.ttf that I replaced); but the KF8 format lost the hack result and display original font.

Would you please tell me how to do to let KF8 format books display a right font hack result?

Thank you very much!

NOTE: Because regenerating the cache takes so much time, we won't try to handle the browser fonts by default, in order not to waste 5 minutes each font switch.

Important note about KF8 files: Please note that in order to use your custom fonts in KF8 files, you will *have* to enable this feature! You'll also want your font's metadata to be consistent: for example, all the Serif fonts should be of the same family, and their styling info should be accurate, or you'll risk having strange surprises, like books rendered in all bold .

That might or might not be enough for CJK fonts though, you might have to tweak the ko & zh overrides in the fontconfig setup... (linkfonts/etc/local.conf)

Hey, Mr. NiluJe, thank you for your quick reply.
But I still feel confusion how to tweak the setting parameters.
Do you mean the step by step like below:
1) Remove the nobrowser file in the linkfonts folder first?
2) How to enable KF8 feature?
3) Which contents that I should change in local.conf file?

Best Regards!

@donnie888:

* Yep, delete nobrowser, then reboot.
* If that still doesn't help (it should at least work for Latin scripts, though), delete the few zh/ko overrides near the end of local.conf (~L394-444), then reboot (or autoreboot).
