That is why I am asking. What will it do?

Provided that the functionality doesn't also change with each update...

That's exactly the point. It would be possible "somehow" to do it, but you'd still have to manually check whether the results make sense. So I use my own manual "heuristic" for finding which class/method has become what. It's still extremely tedious, but at least it's a bit faster than having to find out everything from scratch again.

Allow for customizations. Read the README.

It will steal your soul, but your kindle will sing exactly like Elvis. I know, hard choice....

There is one area of the file system that you can see when connected to a pc - the place where you put your books.
Everything else about the software that runs the machine is outside of that view.

Putting software onto the machine, in the part that you can't see, requires the use of cryptographically signed packages.

Amazon only ships the Kindles with their own crypto certificate installed.
The "jailbreak" for the Kindles installs an additional crypto certificate so that software packages not provided by Amazon may be installed.

With the recent advent of the version 5.3 firmware for the Kindle Paperwhite (Kpw) it has become a bit more than just installing our customization certificate, but the principle remains.

Ahhhhhhh. This is the first time I really went looking. I now see that Collections file (whatever json) is no longer visible/accessible. That was the one I could tweak on my k3.

Hmmm. More investigation will be required.

So could someone explain the next steps after this jailbreak to complete the screensaver override? That's the piece I miss.

Hello.

I have done the jailbreak by the following method:

My question is, can I update my paperwhite directly to 5.3.1 version?, or should I have remove jailbreak before update...

Thanks ;-)

You can update directly, and if your jailbreak version was recent enough, it will be automatically jailbroken again right after update. Please note that this update is a full reflash, so it'll override everything you have modified on main partition.

You can safely update from any previous PW version - jailbroken or not - to 5.3.1.

I highly recommend to re-apply the jailbreak once you're on version 5.3.1. This will make sure that all the required files are in place, even if the firmware update wiped them.

Thank you very much, tomorrow i'll do it ;-)

The screensaver hack isn't working for me (update is greyed out) so can I assume that the kindle has been correctly jailbroken? I did the press on the left corner on that document and it said my kindle was being liberated etc, but maybe it hasn't worked?

Cross posting to multiple threads here is a good way to be ignored.
