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

@BryanW: Well, your corrupt vBulletin downloads issue is certainly weird ^^. Glad you got it working in the end though .

Jailbreak and SS hack went off without a hitch, thanks to all those involved.

NiLuJe your instructions were orderly and easy to follow.

Hi, since I got a Kindle 2 international, during Kindle 2.3.x days I installed the font hack that prevents firmware from automaically updating. Why do you had to prevent the update? 'Cause update brings about Kindle's "bricking".

For now no hack is installed into my Ki2. Can this "Fonts & ScreenSavers hacks for Kindle 2.5" prevent the auto-update of its firmware?

Hi all,
I'm tried to enable internal User Screen Saver capability. But it seems not finished or buggy and not work at all (in 3.0.2 firmware). But, if developers fixed bug,You can enable it by:
1. Place you images in sleepscreens/600x800 folder in Kindle's root directory.
2. Enable User Screen Saver feature by editing /var/local/java/prefs/com.amazon.ebook.framework/prefs and add this line:
screensaver.enable.userdefined=true
I hope, this information will be helpful for next SS Hack's

NiLuJe, is there an issue with Droid zip in your first post? I have just tried to do the font hack for this for a new kindle3; four times, downloading the zip each time, and twice I had to reload the original fonts in order to be able to get the kindle functioning again, setting it to factory default. I tried on a different computer (XP not windows 7) and that still didnt work, each time reloading the original fonts was the only way it would start functioning again. The first time I thought it was because it was indexing; but the factory reset got rid of all the books, but second, third and fourth time still failed. The original font hack worked, just not replacing it with the droid. Any ideas?

I am hoping that one of you Linux experts might be willing to be help me out with one of the Kindle 3 hacks. I am willing to pay a reasonable amount for the help. I am a very experienced software developer (coding since 1964) but never got into Linux.

Basically, I need someone to work with me to disable the screensaver on my new K3. There is a reference to this here:

https://www.mobileread.com/forums/sho....php?p=1098081

In another post it looks like setting ~disableScreensaver works but I am not at all sure how to do this.

There have been some interesting comments about this entire issue of being able to turn off the screensaver. Personally, I can't understand why Amazon didn't provide the capability of setting the timeout value or even turning it off with the latest firmware. One of the major things I do with my Kindle is used it for recipes. Even with the recent firmware upgrade on my DX which increased the screen timeout to 20 minutes this is typically not enough for most of my recipes. Hitting the switch to turn the screen on is a bit of a hassle since I have the Kindle in a protective splash proof cover when I am cooking so I have to partially remove it to access the switch. It looks like the K3 has a shorter timeout so this problem is even worse.

If one of you is willing to work with me, you can email me directly at: eharris &at& synnovation.com. I can easily set up my system for remote access and control so this hack will probably be fairly easy to do remotely.

Thanks,
Ed

@ArtSalt: No.

@Sir Alex: Aha! I knew it . Great find! We can't easily muck with the framework ourselves, though, so it's unlikely this could get fixed via a hack, but it's nice to know more details about that nonetheless .

@Pushka: Not that I know of, it's basically the same fonts than those installed by default by the hack, and I used those for about two days without any issues... What happened exactly after putting the fonts & doing a framework restart?

@choclit: ~disableScreensaver works. (kinda). The only downside (AFAICT, never tried it myself) is that it disables the sleep mode (suspend) altogether... There was a way to change the sleep timeout on FW 2.x, but I haven't taken a look at that yet on FW 3.X.

We discussed this a bit a while ago, so, to answer isotherm's idea:

lipc-set-prop com.lab126.powerd touchScreenSaverTimeout 1

only resets the timeout to the max (ie. 600s).

(Didn't test preventScreenSaver, suspendGrace & deferSuspend though).

Possibly this has been answered before, but 46 pages of discussion don't make a search any easier.
I have a Kindle 3 and I would like to use Times Roman reading books. Would this work:
-jailbreak
-install font hack
-rename my Times Roman fonts on my (Windows) computer to Serif_*.ttf
-put them in the linkfonts/fonts dir

Would this work? If not, what would I have to do to get Times Roman?

[NiLuJe]

@bartveld: Yes.

Thank you NiLuJe.

My local forum just reached this post and what they did was this;
1. They dropped i18n, CJK.ttf and kept separate C,J,K fonts as original 3.x FW scheme for easier font change and replaced each Asian fonts with new ones. For this the original font.properies file was used.

2. The fallback font, code2000, was edited with new local font sets. (keeping consistency with each Asian fonts replaced)

Nobody is really sure about 'hint' thing though.

[NiLuJe]

@test011: Great

I'm not sure what the impact of good glyph hinting is on CJK glyphs to be honest, but I expect it's far more noticeable than on latin scripts, which explains why a good number of CJK fonts used to use bitmaps glyph, but basically, on the K3, if a font looks fuzzy, it's because it's not hinted .

But on the CJK front, I expect that anything remotely recent must be at least partly correctly hinted, because otherwise outline based CJK glyphs pretty much look like mush. ^^

@NiLuJe New to the kindle (I just got my kindle 3g) and I can't for the life of me get the usbNetwork to activate. It installed fine and the log said done, I run ;debugOn then ~usbNetwork wait and nothing happens. I've plugged it in and it always gives me usb drive mode. any explanation or anything I can do to fix it?

@rumblpak That's pretty weird... PM me your install log & syslogs (;dumpMessages).

I'd be happy to but all that is creating is a single all_logs_as_of_Mon_Sep_27_14.54.35_EDT_2010 file that is 8MB which I don't think is what you want. If it is just tell me and its on the way.
