Why Kubrick cannot work for installing the original firmware? (the one the device had on when shipped) I did a bit of searching through the forums and found that it won't apply to KT2.
Thanks!

Kubrick requires a device to be in USB Downloader mode, which is activated by holding down a physical button (i.e. a "magic key") on the device while powering it on. Devices newer than a K5 have no button to hold. However, most of them DO have internal pads (somewhere) that connect to the same BOOT0 and/or BOOT1 (USB boot mode) bins on the SoC device, but so far nobody has figured out how to use them AND it would still require opening the device to connect to those pads on the PCB. And while open, you might as well do the serial jailbreak that we DO understand. Amazon is NOT making it easy for us, and in fact is trying hard to NOT allow us to use our kindles in ways we prefer (by attacking our rights as owners of our own kindles).
TL;DR -- KT2 (and newer) devices lack a "magic key" required by Kubrick.
