Basically /var/local/eink/isis.wbf is the default waveform you need for the kindle 3 to load if your eeprom is empty.

To make a complete list of steps, you need:
1. Jailbreak and install usbnetwork, https://www.mobileread.com/forums/sh...ad.php?t=88004

2. Enable usbnetwork to automatically start when usb is connected, so you can quickly experiment with a few different waveforms. Check the readme of usbnetwork package.

3. When kindle started, connect usb to your computer and ssh to it. Link a pre-stored waveform from /opt/eink/images/ to /var/local/eink/isis.wbf, reboot and test.
ln -s /opt/eink/images/xxx.wbf /var/local/eink/isis.wbf

For me only the oldest wbf works, maybe my new panel is really an old model.
The K3 shipped with at least three different models of panel during its production life-time.
So a bit of experimentation to get the best match between the available files and the panel can be expected.
