I really hate that that "jailbreak" overwrites Amazon's key when it doesn't need to.

So I repackaged it to create the key uniquely. This also means that the jailbreak doesn't ever need to be uninstalled. I've attached the updates for all 4 models.

Also, I repackaged the screensaver hack for all four models as well.

[EDIT:]

Screen saver install directions:
1) Install the jailbreak. The update will "fail" on the kindle, but will create a certificate that will verify our signed hack packages.
2) Install/Uninstall Screen Saver bins as normal.

[Edit again:]
A single backslash prevented the old uninstall scripts from removing the version tag. This has been fixed, and the new uninstall scripts work as expected. I'm sure I'll get a million people yelling during the next official update, however. oh well.

Is this safe for us to do to our Kindles?

Thanks. I just tried it on my K2-US and now have my custom screen-saver again. Looking forward to my Georgia2 font before too much longer, I hope.

Follow-up question: do you need to run the "jailbreak" first, or just install the screen-saver file? (I did both, but I see a report and KindleBoards that someone else had success just installing the screensaver file.)

The jailbreak file does not work on my k2i.

The screensaver hack did work without installing the jailbreak file for me.

I believe it's expected that the jailbreak will report as having "failed" when in actuality it did what it needed to do to make it so that the actual screensaver install file can work.

Did someone move the files? The link seems to be invalid.

Yes. porkupan's jailbreak installs the certificate on the kindle. We need this there so we can sign our hacks with the key, and have the kindle verify it and allow them to install.

Also, I didn't include an uninstaller for the repackaged jailbreak, since the jailbreak doesn't change anything, it only installs the public key to /etc/uks/pubhackkey01.pem . And this should never affect an official update. If it turns out later that amazon specifically writes an update to fail if that file is there, then it's a simple case of making an uninstaller that simply removes the key.

No, I was updating the archives to include the source code, and fix a typo in the uninstall scripts.

Oh, I sure hope you're right, NogDog! I'm holding off on manually applying the Kindle update. I just can't give up the font enhancements.
