ok, now I'm lost.
it seems one needs to use this from the kindle, but mine is useless right now. how could I test this?
as for kubrick, I'm fiddling with it right now... I'm searching for the tools.
I used the standard linux shortcut ctrl+alt+F2 to access the root console.
still searching for the tool to send a uboot to the kindle

mfgtools if I understood
I'm trying, but with difficulties, to understand this
