Download the jailbreak, install it.
Phew, you're safe now. 
OK. The latest versions of the Kindle firmware, fw6.6.x, has blocked the methods we used to obtain root access. However, the jailbreak, if previously installed, will be preserved when upgrading to fw5.6.x.
Third-party sideloading has not been affected by the new firmware at all. However, our aftermarket addons include tools for managing collections via calibre (see the calibre plugin "Kindle Collections") -- like all aftermarket addons, this requires being jailbroken. 
Once jailbroken, there is no real harm in upgrading. The only old firmware that is worth holding onto for dear life is fw<=5.4.0, since it doesn't have Cloud Collections. Also, since it doesn't support Cloud Collections, it supports nested collections via Collections Manager Kindlet. |
Thanks so much for the in-depth reply.
I copied zip files onto USB device USB folder, unpacked them, ejected & unplugged the PW, and then went to *[HOME] -> [MENU] > Settings -> but did not see the option to "Update Your Kindle". I'm wondering if this is because device is unregistered which would of course would require that i turn on WiFi etc.?
