Jailbreak only works half

Bebef · Today, 10:36 AM

Hi everyone.

I tried to jailbreak my Kindle Paperwhite 3, but somehow ended up with something only half-working. I did the installation as described on https://kindlemodding.org/. I installed KUAL and MRPI. I can put packages in the /mrpackages folder. When I run ;log mrpi, I can see the package installers run on the screen. The package will vanish from /mrpackages However, the installed things won't work. I can start KUAL, but I can't start KOReader. When I install the screensaver, the sample picture will be displayed until the next boot.

I'm pretty sure I followed everything to the letter, so I'm wondering what might have went wrong (and where).

Cheers,
Steffen

What are the exact steps that you followed to install KOReader?

Like I said, I followed the instructions on kindlemodding.org. Applied the WinterBreak (https://kindlemodding.org/jailbreaking/WinterBreak/), installed the hotfix and installed kual and mrpi, exactly as described there.

Did you fill the storage? Your PW3 is so old it hasn't gotten updates for a couple of years and you don't need to worry about an unplanned update while the jailbreak is being done. If you did fill space, free up about a GB and try installing MRPI and KUAL again.
