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

[Barty]

Re font hack, I'm trying to get tighter line spacing by playing with my custom font's metrics -- ascender, descender, etc. When I preview the font in Windows, I'm seeing tighter line spacing, but when installed on PW2, there's no effect. Seems like the reader just ignores the font metrics values and calculates its own. True?

Double check that you're not using (old) mobi format for your books.

I'm using modified (edited via Font Creator) Bookerly on my PW3. Don't have jailbreak so I'm embedding font files to every azw3 book

The firmware in your PW-3 has the new layout engine.
Barty did not post if that PW-2 had been updated yet to the newest firmware.

@Barty: I vaguely remember posting a FontForge screenshot of what the Kindle renderer actually cares about when tweaking these things. With a bit of luck, I linked to it in the FAQ. If not, try doing an attachment search on my nick, the screenshot would have been a PNG.

But, yeah, what @shamanNS said holds true, I don't remember how the mobi6 renderer behaves on that front, so I'm talking about KF8 here .

And potentially forget about KFX, too, since that's a whole other can of worms... .

Thanks all. I'm on an old fw, like 5.4.3 or something. Don't want to update because I don't want to mess my jb. I'm using Mobi because the kf8 renderer has even bigger line spacing. I'll give azw3 another shot and try to find NiLuJe's post.

Hello!
(me again)

I have the same problem:

The kindle show my customs ScreenSaver,

But I want to show me the cover of the last book I opened.

I tried 2 things:
1. creating the "cover" file in "linkss" folder (didnt work)
2. via KUAL
2.1 open Helper+
2.2 Select "ALLOW ScreenSaver" (a check mark is showed)
2.3 Head to "Screen Saver" Menu
2.4 select "COVER MODE BEHAVIOR" and select "White Borders"
then "QUIT" option.

I opened the book, read a couple of pages, then push sleep button...
... and I keep watching the wonderwoman picture (not the book cover...)

some clues:

1. Should I erase all the pictures in the ScreenSaver folder before activating COVER Mode?
2. Does it matter the resolution of the cover incrusted in the .mobi file?

thanks a lot for your time!

Toggling cover mode requires a framework restart (at the very least).

jum... man... I didnt read that... I think...

thanks thanks thanks again!

So, for anyone figuring out how it look in the kindle PW2:
---
I followed the same steps writting before.
+ framework restart:



Happy to see you again!:


Open my current reading book, read a couple the pages and press the sleep button:


guys!

I should probably put that requirement in the KUAL status message triggered by the cover mode button, just in case .

Really? do you mean this thread: Kindle Touch/PaperWhite ScreenSavers Hack (its your thread by the way )
Or you are talking about a wiki page?

In the other hand: It could be a IRONIC message... I dont catch ironic in english

It is already in the installation instructions of the SS Hack top thread.

I read that as being an additional (reminder) message written to the status area of the KUAL menu.

Another choice, for the K5 and older, is to ring bells and blow whistles (meaning: restart required).

[NiLuJe]

Yup, what @knc1 said .

[MrCaringi]

So right!

it is here:

"Do you want to use the cover of the last book opened as a screensaver? Make sure you've installed the Python package first, then just drop a blank file named cover in the linkss folder. Restart your Kindle ([HOME] -> [MENU] > Settings -> [MENU] > Restart; or simply use the Screen Savers > Restart framework now button in KUAL), and you're done ."

I read it but totally forgot! sorry guys...
... and thanks again!

following the tutorial to the letter baring in mind this is my second kindle that i am attempting to jailbreak. first was wifi only this time it is a 3g that i am struggling with. i now that they are different files etc which i have downloaded and putting the correct one on my 3g but i keep getting an error u007 when restarting after putting on the file and disconnecting and then restarting i had no problems with my wifi only one worked first time.

i have tried a few different jailbreaks to see if it was just this one that didnt work but again still get the error,

have removed all books etc reset back to factory settings and still get the same error.

@alilou85: is this perchance a second-hand device?

Because a U007 error usually implies that the device is already (half) jailbroken...
