A note from Bookfere may be useful (sucessful on my kindle oasis3 with 5.17+ and WB)
Regarding the installation of the screen saver hack for versions 5.17 and above:
After jailbreaking, ensure that KUAL and Mrpi are functional.
Then, install usbnetlite via MRPI (
https://github.com/notmarek/kindle-u...ases/tag/1.0.M).
In KUAL, select USBNetLite -> Toggle USBNetwork.
Connect the Kindle to the internet, and SSH into the Kindle from your computer: `ssh root@[kindle IP] -p 22`. (The default pw is 'kindle')
Using WinSCP, execute the following commands in sequence:
1. `mntroot rw`
2. `ln -s /lib/ld-linux-armhf.so.3 /lib/ld-linux.so.3`
3. `mntroot ro`
After completing these steps, you can proceed to install the screensaver hack using Mrpi as usual.
