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.

New subject: Motorola C139 V1.9.24 Won't Load from osmocom-bb
Hi,
I had a similar problem with a tracfone branded c139 (ftmtool error). On
IRC, Hoernchen mentioned an older post where the author "fixed" the
bootloader. He also mentioned a pastebin that referenced a tool called
mot931c. I managed to find it and could successfully reflah my tracfone's
bootloader, which now loads osmocom-bb without issue. Here's the reuploaded
software package:

Hi,
It should be noted that the new bootloader is very limited (no charging, no
loading of the regular phone os). I found another tool, called "C139 FULL
SOLUTION UNLOCK AND FLASH", that successfully could flash a proper firmware
(European_Software in the archive it is version 1.0.03.E):
https://drive.google.com/file/d/0ByHQWL5Q6bSwTWdhRFAyU05uLUk/edit?usp=shari…
Nonethless this particular (trac)phone is still limited to the US bands.
