ScreenSavers hack without python

It's been long time since I posted here. Mainly because I started to use my kindle for… reading books.
I almost completely switched to ebooks and recently I discovered that I really miss one feature of a paper book – a cover. A cover that helps me to visually remember a good book, its title and author. And then I recalled NiLuJe's screensavers hack.
As the python installation takes a lot of space I thought I could replace python tools with my mobitool binary. I gave it a quick try and it works fine. The downside is I had to drop KFX support, because my tool does not support it. Anyway for my use it is not needed as I don't buy books on Amazon. I am posting link to my fork here, in case someone will find it useful. Bear in mind it is a quick mod of the original work, only tested on KT.
Thanks again NiLuJe! I am looking at the cover on my kindle's screensaver now.

@baf: Great minds think alike .

I happen to have a watch on releases of your MOBI implementation, and I just saw the mobitool cover thing, and I was just thinking of looking into trying it out .

As you said, can't really drop Python entirely because KFX, but that'd still allow me to drop my outdated and mangled copy of KindleUnpack that doesn't support Python 3 because I'm too lazy to rebase it ;p.

@NiLuJe
I added cover feature to mobitool just for the sake of screensavers hack mod. Just a few lines of code. Glad it may be useful for you.
BTW I didn't realize the ss hack is such a complex code. Impressive!

I also don't buy books on Amazon (mostly), but I do use the KFX format through excellent KFX output plugin, 'cause they display much better on the Kindle. I wouldn't dismiss kfx that easy if I were you...

Interesting, but now I realized that KFX is probably not even supported on my old Touch with 5.3.x firmware.

Question Random Screen saver hack isn't working

I Python.
I have latest python installed + screensaver hack
Although cover hack works fine but custom random image hack isn't working

FW is latest 5.13.1 can I have old builds of SS hack to try them or install specific python version?

As default it automatically switches screensaver to lastscreen hack

@Kinki: That's just because you have broken images in your image pool. An old version won't help you, that codepath doesn't depend on Python, and hasn't been touched in *years*.

See the docs/FAQ.

You'll also have to reboot the device, once the ScreenSaver code hits an image it doesn't like, it's stuck until the next boot.

Failing integrity check when installing on Touch

Hi there, first time posting on this forum so please bear with me. I've just jailbroken my Kindle Touch and I was following the instructions to install the ScreenSaver hack. However, it keeps failing (After checking the package, it immediately goes to "Destroying Package"). Here is the MRPI log output:

Spoiler:

I don't really understand the output, since I would have thought the integrity check would be one of the most basic checks to pass and I'm not sure why I would be the only one to have it. My "Update Your Kindle" IS greyed out, though I'm not sure why. I didn't update my Kindle after jailbreaking it.

What I've (not) done:
I didn't modify the file.
I ran Install MR Packages with the kindle unplugged.
I am not subscribed to special offers.
I'm planning on using the cycle mode.

This might or might not be relevant:

Spoiler:


I previously encountered "Illegal Instruction" error before I got the "Integrity Check fail" error,

but I think it was fixed after I reinstalled jailbreak because the error became the Integrity Check fail error.



Would appreciate any help! Hope my time spent finding nice wallpapers wasn't wasted

That vaguely look like the *very* first build I pushed yesterday.

It was *very* broken ^^.

The current build should only be *slightly* broken, but it mostly passed and worked on my PW2.

It's still broken on Kobo, though, so new stuff is currently baking, should be ready in a few hours.

For the ScreenSaver hack? I actually went on to try installing Python 2.7 and LibrarianSync using MRPI yesterday but they both failed multiple times due to "Illegal Instruction". So I was actually wondering whether the error was due to the ScreenSaver hack or MRPI... I know this is slightly off-topic but did you also push a new build for MRPI?
