[HTC One X] Vcek:
Interrupting the flash doesn't work without pulling the battery, it will lock you in ruu mode until you properly flash the bootloader

Interesting link regarding talking with HTC hboot over serial-links and radio (probably with microsim connector)

Some interesting pulls from diag.nb0(could be of some help with Trip's hacked Fuse)
