I just used winterbreak to jailbreak my Kindle Signature 12th edition, which is 5.17.0. The jailbreak was successful. I the installed the MR Installer extensions and mrpackages folders, followed by trying to install the KUAL bin file (placing it in the mrpackages folder and invoking ";log mrpi" from the Kindle's search bar. However, I'm seeing the following error in the MR Installer's log file:

I checked, and the K5/kindletool app *does* exist. Maybe the mount point path has changed for internal storage on the latest Signature device? I would appreciate any help/advice anyone can provide. Thanks.
