I have just posted flash images read out of two C139s and one C140,
along with an annotated disassembly of the bootloader and other
reverse eng notes:
Hopefully someone will find it helpful...
To the OP: in case you haven't already figured it out, you need to use
-m c140xor with C139 and C140 phones. I don't know what phones would
-m c140 (w/o xor) be correct for, if any. Sylvain's direction to use
the -c option as well (and then use *.highram.bin instead of *.compalram.bin)
is also correct, because the images are bigger than the ~15k max one
can download w/o -c on this phone.
Also you said your C139 came with fw version "V1.9.24" - are you sure
it isn't V1.0.24 instead? The imprint on those stickers is a pain to
read, too small... If your fw version is actually V1.0.24, then it is
the exact same one I have just dumped and reverse-engineered.
