Kindle 2 - Is it possible to make the Full Screen Mode default?

[supakdee]

Hi,
I would like my Kindle to use Full Screen Mode as default (instead of press "F" every single time open any documents).
I search through the posts already but could not find the way.
Any one know which parameter might do? I can also use USBnetwork to change it.
My Kindle is K2i ver.2.5.8
Thanks.

One more - Anchor to Top Right - I always read Japanese Manga - If can put Anchor to Top Right as default, it'll be perfect.

It is possible, but not easy.
If you send me file /opt/amazon/ebook/booklet/PictureViewer.jar from your kindle I can make changes in it for enabling fullscreen by default. I already did it for my Kindle 3 device

Hi proDOOMman,

Thanks a lot.

I attach the file with this email.

I'm looking forward to seeing your reply.

Try this hack: https://github.com/downloads/proDOOM...screen-0.1.rar
It hack contains patched PictureViewer.jar and init script
After installation you need to reboot device manually!
Don't forget to patch whitelist

Also I wrote universal version for any Kindle device: https://github.com/downloads/proDOOM...n-hack-0.2.rar

Hi there!
I tried to install your 0.2 update. My Kindle said the update was succesfull, but nothing changed. In fact the log file says:

ota_install: I def:update::patching PictureViewer jar

My KDXG is on 2.5.5 firmware, do I need to update it to 2.5.8 before I can install your patched viewer?
EDIT: installed 2.5.8, but the log file is the same.
Or could it be because I didn't update the whitelist? I can't find that file in my Kindle.

Java on KDXG so old
I made fixes and upload new version: https://github.com/downloads/proDOOM...n-hack-0.3.rar
Try it

Hi proDOOMman,

I installed it - automatically restart then restart one more time.

It works perfect.

Thanks a lot

Universal patch, nice.

Just by curiosity I wanted to see how you did this so I retrieved your source:

Spoiler:

1- extracted the .tgz from your .bin install
2- unzipped the .tgz to get the .tar archive
3- extracted the .tar archive and got the PictureViewer java archive
4- extracted the .jar and got the PictureViewer.class
5- decompiled the .class to finaly get the PictureViewer source text file

But I am no more advanced I am looking at your "package pictureviewerpatcher" and I totaly don't understand where/how you patch that full screen option.

If at all possible, would you care explaining the source a little -- in java noob terms?

Thanks

[proDOOMman]

This patch just makes some simple manipulations with java bytecode using javassist library. Procedure "processJar" unpacks PictureViewer.jar, finds "g.class" file, sends it to "ProcessClass" procedure and pack jar again. "ProcessClass" adds to end of method "g.stop" call of function "m()" (this function triggers fullscreen mode) and adds to method "g.stop" disabling of fullscreen flag - variable "D".

Much appreciated proDOOMman. Thanks again.

Just tried this out on a Kindle 3 Wifi v3.1 and it works great! Thank you!
