So I got to,
==========
Download and install the current 'hotfix'
The current version is attached to its release post, see:
Jail Break Survival Code
Spoiler:
Unarchive the release archive package.
Connect Kindle to PC with the USB cable.
Place the Update_jailbreak_hotfix_*_install.bin in the topmost, visible level of USB storage (alongside of /documents).
Eject and/or Safely Remove (term depends on OS) the Kindle, USB storage.
Remove the USB cable.
get stuck here --------> Home -> Menu -> Settings -> Menu -> Update Your Kindle
but I cannot update the kindle, but the file is there in root initially. and the "update Your kindle" is briefly black for a second and goes greyed out and the hotfix file disappears from root
So its applied itself? which sounds weird....
