no update, i've not had any time at all to look at it again. but it seems i'll have some free days soon
i'll need someone with such a bricked bsquare device, who can test stuff.
again to sum up, we can try:
1
) flash a modified OS which doesn't ask for password - very easy to mod the OS after we find out how to flash it at all
2
) find password calc routine - well hidden so far :/
one idea right now for option 1
). as i said the bootloader tests for several key combinations, all of them consist of two keys.
i've not had the chance to try all combinations on mine. i understand the disassembled code but i don't have the physical wiring of the keyboard
(i'm not disassembling the hardware of my bsquare for this
), so either someone provides me with a wiring or try all combinations, if you feel like trying
the known ones are
B+C hard reset
U+D usb download
(which won't be useful for us as we do not have the PC side program for downloading the OS over usb. i doubt platform builder can handle USB, something else is needed to emulate it for PB, and this is what we are missing here
)
S+D or S+R i forget right now
, this i think looks for a SD card, which sounds promising. but whatever it looks for if it doesn't find it, it will hard reset just like B+C.
please help get more key combinations, iirc there are five or six in total - i'll check disasm again
