If I get my hands on newer devices that I can risk by opening and poking and prodding, I plan to find a testpoint or via (or more likely a resistor) that connects to the "magic pin" that enables USB downloader mode. It has to go to one of the pins that sets the boot mode (which need to be tied to resistors, and perhaps some sort of electrical switching mechanism). They must be routed to resistors, which must be on a top or bottom layer (at least according to my understanding about how these i.MX SoC devices work.
We just need to figure out which side of which resistor to short to ground without releasing the
magic smoke, and we can adapt Kubrick to these new devices too...
