@twobob: Thanks for your input. I've began typing my previous post right after @Ixtab reply to my first question, but didn't finish/post it for next 30+ minutes So I didn't see your's 'till after I've posted mine.
Now that I've read it I can see that pre-edited .jar file don't work on KK fw 3.4.

So I'll try pulling files and unpacking them in a couple of days. My USBnetworking hack works over WiFi,and I don't want to be autoupdated to fw 3.4 (waiting to see how the Calibre generated .apnx files problem with azw3 turns out ) when I turn WiFi on on my Kindle,so.. this will have to wait.
Or probably I should wait for someone else who has already setup-ed debricking & custom kernel with recovery to try this modification on KK with fw 3.3/3.4 ...

p.s. I know that I could just pull phone/ADSL cable from my rauter/modem ,but I need my internetz Downloading stuff...

Or
You could firewall the Kindle from Amazon updates in your router;
Or
You could firewall the Kindle in its own rules, of the 3.3 image you are going to install, before you install it.
Or
You could apply one of the "disable OTA update" hacks to the 3.3 image you are going to install, before you install it.

All of the above described here at MR.

Err. then just amend your autoupdate script thusly...


Line 42 - 47 /usr/bin/process_update

Quote:
# Start updatewait in background and exit
# ${_UPDATE_WAIT} &
# msg "Started ${_UPDATE_WAIT}" I
msg "Auto updates are disabled, exiting..." I
exit 0
fi
AFAIK that does the job...
Manual updating would still work should you choose to.
Nothing else would be affected AFAICT.

Then simply revert if you want to go back to autoupdates.

Enjoy.

@knc1: My Kindle is already on fw 3.3.

Also, I could "firewall" using Windows hosts file

@twobob Any kind of file editing (outside of "USB partition") requires USBNetworking, which works over WiFi in my case. Anyhow, I currently don't have time for editing and SSH-ing ( ), so no need for firewalling and disabling auto update.

For the record, I "hot-edited" mine (on one 3.3 device) in exactly the way you describe just the other day. The edit took what? 20 seconds? It's a big update compared to that.
As it happens the update wasn't actually pushed down for quite a while.

I have ZERO Idea of their update scheduling, : )

Also... just one tip:
I could "firewall" using Windows hosts file, no, you couldn't, well you could but it wouldn't do zip, but... moving on.

Perhaps catch you when you have a bit more space for the project.
Laters...

and I'm glad you are enthused about the prospect of being a hack author

@alansplace: Not necessarily the right place (or, more exactly, thread), but:

If they're mine, you should have stuff with the right info in the linkss/info.txt file on your Kindle. That should point you in the right direction (and, in the case of my stuff, you can safely use the uninstallers from the latest version, they handle all previous versions fine).

I saw that and removed it here and put it as a new thread like I believe I should have done in the first place while you were replying, sorry. See you there, ok?

In my case I have 3.2.1 firmware on DX, and I did this hack for my device. I don't have any other devices.

I wrote the steps how I did that hack in my instruction. So now everyone can make same things with his device.

What is the difference between my device and yours? The difference is the fact that your version of MobiReader (java app which is resonsible for rendering book on screen) may be different. The jar files in your case will have different resource classes with different names in comparison to mine, and those classes may have different array fields.

So, you have first to find where are those arrays that have to be changed.

I would suggest you to search for them in following way:
1) copy all jar files that you find in \opt\amazon\ebook\booklet\ and \opt\amazon\ebook\lib\ directories to your disk.
2) download JAD and put it to PATH
3) for each jar file which you found and which you suspect that it will have that array that should be changed, do following steps:
4) create a powershell file

get-childitem C:\Projects\MobiReader\ -include *.class -recurse | foreach ($_) {jad.exe -d $_.directory -s .java $_.fullname}

(MobiReader dir in my case is the dir where I unpacked MobiReader.jar)
this will decompile you all classes recursively and will create .java files for every .class file. This is for Windows machine (I am windows programmer). If you have Linux - I don't know how to automate it to avoid running jad.exe eachfile.class for every file separately.

5) in Far Manager (or any other tool you like) do search for "font.size.list" or for "17,18,21" in all java files you've just made. The latter string I made by looking at what sizes are set in FONT_SIZE parameter written to \mnt\us\system\com.amazon.ebook.booklet.reader\rea der.pref file after I increase font size one by one - IN YOUR CASE FONT SIZES MAY BE DIFFERENT.

In case of Kindle DX with 3.2.1 firmware there are 2 such files that are responsible for font sizes:
\opt\amazon\ebook\booklet\MobiReader.jar
and
\opt\amazon\ebook\lib\framework-api.jar

In your case with different firmware and device, you may have different set of jar files and different classes that contain a (hardcoded) array.

But you'll have to find it on your own.

6) after you find it, follow my instruction to modify it, recomile, jar and put back to your device.

I've just made an experiment - and it works. There can be a choice of not 8 but more font sizes. I've made 11 options:



For this I modified the array
\framework-api\com\amazon\ebook\framework\resources\UIResourc es_en.java
like this:
"fontmenu.default.font.size.list", new int[] {
21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31
}

I wonder if you could find an option for "Words Per Line" and ditch that gutter...

Like "Max!" "Normal" "Useless"

I would heart that oh newly-crowned master of text tinkering : D

@ihor: Nice work. Only if it head different/modified icons, that indicate size it would be perfection

@twobob: Yeah, permanent margins change would be awesome...
