Jailbreak is for installing anything to root partition - and yes consist of nothing more than a dev-certificate. The rest is window dressing and a clever way to copy that key where it needs to go. Kindlet Jailbreak is for active content to run (and maybe break out of their sandbox? not sure on that).

FYI, next time when you ask a question, would be nice if you don't edit it out only because you found an answer. Leave the question, and say you found it and what the answer is (or where). MR is not for your benefit, it is for everybody's benefit. Somebody else with the same question and no solution would like to hear what you found out.

Sorry about that, I think my main question was whether either one of those type of JB's ever needs updating after initial installation. As far as I found, no.

@ixtab, in thread about kindlepdfviewer there was a discussion about KPVBooklet, relying on some stock Amazon Java classes. It searches required method in class by it's signature, so it can resist to obfuscation. Maybe this way will be suitable for some of your patches.

Normally that is correct, but sometimes you need to update - e.g after an update of the Kindle.

Interesting idea, but it can only be applied in very specific circumstances. It's not suitable for patching classes - even if the method to be patched could be unambiguously identified (the approach only works for them because there is only one method with the given signature in the class), simply going ahead and modifying bytecode that has not been manually examined is a lot like playing russian roulette.

BTW, I am already using something (roughly) similar here.

Recently added the JBPatch (mostly because I could

...Thanks Ixtab!) and found that I really ,REALLY like the hypenations. It's amazing how such a little thing can make a big difference!... so now I'm tempted to try the margins: does anyone have suggested margin settings/adjustments that they like for standard mobi books? Thanks

i upgraded to 5.3.2 and new firmware is awesome, but i realized that i cant read without jbpatch customizations =| i hope ixtab or someone gets a way to at least customize margins. And yes im no developer and cant program crap... in the meantime ill listen emo sad gay songs on youtubs =|

You really should. With margin and hyphenation you get a 20% more text on a page.

I have:

10 for top margin
10 for top margin offset
25 for bottom margin
25 for total bottom margin height
15/15 for left/right margin in PDF
15 for (left/right) margins in non-PDF with default words per line
25 for (left/right) margins in non-PDF with fewer words per line
40 for (left/right) margins in non-PDF with fewest words per line

My KPW(5.3.1) is bought from japan.
I followed the step described in the README file.
But after I put update_jbpatch_3.1.0_fw531_install.bin on the device,
I found menu/settings, menu/update your kindle option was grayed out
Any help please
thanks

twobob · 01-14-2013, 01:23 PM

well assuming that you did transfer if over USB... and then eject?

Did you do that - or SSH it onto the device?

sabonis · 01-14-2013, 02:40 PM

uhh~ I tried two of following
1. eject device -> plug out usb connector
2. plug out directly
same result (update is unclickable)

I didn't try ssh, cos I don't know how to do that by ssh
but I did know how to ssh to my KPW device.

I've tried many times to reset the device and reinstall KPW 5.3.1FW,
and follow the step in the README all over again and again and again and ...

If there are any information I left to show u , please tell me
Thank you!
