Question To jailbreak a unjailbroken old-version device which being autoupdated?

Hello everyone,
I just buy a kindle pw2, and I didn't know 5.6.x can't be jailbroken unless you open it. It is my fault and I've learned a lesson.

This kindle was bought by a seller from Japan, May 2014.
And I bought it from the seller online.
The 5.6.x version was first released in Dec. 2014, right?
If I don't misunderstand, my kindle is not installed with 5.6.x., and it was auto-updated to 5.6.1.0.6 just after I turned it on.

So, please let me know:
Is it possible to jailbreak a kindle pw2 which was never jailbroken, not installed with 5.6.x but, unfortunately, autoupdated to 5.6.x?

Sorry for my poor English, and thanks in advance!


ps. I just want to install koreader because I need to read lots of PDF files.
I dare not open it! With my hands messing on it, it will absolutely become a trash!

Nope, doesn't matter what the initial factory status was, what's on it *now* is what matters.

AFAIK, the PDF component of KOReader uses parts of the k2pdfopt code for the reflow feature. If you have lots of PDF files you may want to check out k2pdfopt, which allows you to reformat large pdf files for 6" screens.

I'm thinking if I should open it

Thanks

Installing this need not jailbreak, or I have to reflow and output a new PDF and then send to my kindle?
Thank you

k2pdfopt is a standalone pdf-to-pdf converter. I.e., it takes a large .pdf file and reflows the text so that it fits a Kindle screen. Afterwards you'll have to manually copy the new .pdf file to your Kindle.
It's fully automatic, however, you can also customize the converter to get better results. For more information also see this thread.
