[Bitpim-devel] audiovox 9900

[Dustin Sacks]

Hello,
I am trying to get access to the media files on an audiovox 9900.
Specifically, this phone is able to record short video clips which I would
like to examine.

BitPim successfully connects to the phone and gives a filesystem, however
the media files are nowhere to be found. In fact when compared to the
filesystem I get when I run BitPim with an LG4400 the 9900 filesystem
appears very barren.

The root of the filesystem has these entries:
$SYS_RMT
$USER_DIRS
NVM/
RDM_PORT_MAP
VoiceDB/
cnst/

I assume that this phone is just not supported. I have downloaded BitPim's
sources, but I have no clue as to what is required to get the 9900 to reveal
its full filesystem. Could someone point me in the right direction?

thanks,
Dustin

This looks similar to the minimal file system for the Sanyo phones. All
the phonebook and calendar data can be found in non-descriptevly named
files in NVM, but none of the ringers or wallpapers can be found in the
file system. If the video clips are downloadable over the cable, it
won't be through the file system, but rather through other commands
which are probably not easily derivable from first principles.

Unless you already have some software that does it then we can
figure it out from serial port sniffing :-) [BTW I did at one
point send every possible command in the filesystem command set
and they all gave me error codes except for the ones I already
knew about. However there do seem to be some other families of
commands]

The easiest way to find if they are in the filesystem is to make
a complete backup, shoot some video, make a second backup and
compare the two.

Inside the NVM dir there are two files, ERI.BIN and PRL.BIN. Both these
files have a small amount of content at the beginning followed by zeros.

NVM/ERI.BIN contains
HEX:
00000000 55 53 2f 52 49 2f 30 30 00 00 b8 55 00 00 00 00
ASCII:
US/RI/00...U....

NVM/PRL.BIN contains
HEX:
00000000 55 53 2f 52 4c 2f 30 30 00 00 b3 f1 00 00 00 00
ASCII:
US/RL/00........

Any chance US/RI or US/RL could be a directory?

I did a full backup, then shot some video, took some pictures and added a
new entry to the phonebook. After taking another full backup and comparing
they appear exactly the same. So all of this stuff has got to be stored
somewhere currently hidden.
