Hello, may I ask you how you used Kubrick exactly?
I was unable to boot Kubrick using a USB flash drive. I had more succes in a virtual machine, but now I am stuck at "Putting device into Fastboot mode ... Waiting for device".

I have exactly the same model and my device is also on the 4.1.4 firmware. I am unable to install KUAL because of the "This device is not authorized as a test Kindle by the developer of this item" error.
