If that doesn't yield anything you might need to dump the flash (how ? good question ... no idea what option there is without being able to load code. jtag, or chip unsoldering ?), and reverse engineer the boot loader to see what changed.
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.
