[Verizon Galaxy Note 3 Q&A, Help & Troubleshooting] bftb0:
Old thread, but I thought that I would add the following info in case anybody goes looking for the same stuff (Software Assistant) at some later point in time, perhaps from later releases.

It can be found inside an ISO file at /system/etc/autorun.iso on the phone

Also, even if you don't have a working phone you can dig it out of the "cache.img.ext4" file in the Odin tar.md5 tarballs (using a few mad linux skillz).

During Odin flashing, it would appear that much of the region customization (CSC) is performed in the recovery boot immediately after Odin finishes. That is, the "system.img.ext4" image is quite generic, and the CSC customizations are performed by copying them into place during the subsequent recovery boot. If you unpack the cache.img.ext4 file and mount it (details in a little bit), you will find:

./recovery/command

./recovery/sec_csc.zip

The .zip file above also contains the ISO image file. Getting the zip file though requires the skillz mentioned above, just hang on a second! :D

the ./recovery/command file contains (e.g. in the MJE tarball):

--update_package=CACHE:recovery/sec_csc.zip
--carry_out=csc_factory
--wipe_data

and the META-INF/com/google/android/updater-script file (inside recovery/sec_csc.zip) is also quite trival:

show_progress(0.100000, 0);
show_progress(0.500000, 0);
package_extract_dir("system", "/system");

Basically, this recovery boot process just unpacks everything in the sec_csc.zip file under "system/" to right on top of the vanilla system image that was flashed by Odin.

For example, in the MJE tarball, the contents of "sec_csc.zip" are:

OK, finally: the mad skillz. You need to use the Android SDK "simg2img" tool (search for simg2img here on XDA) to unpack the sparse ext4 image file (cache.img.ext4) in the Odin tarball.

on your fave linux distro

$ tar xvf Odin_BLAH_BLAH_BLAH.tar.md5 cache.img.ex4
$ simg2img cache.img.ext4 cache.full_img.ext4
$ mkdir /tmp/mntcache
$ mkdir /tmp/mntiso
$ sudo losetup /dev/loop0 `pwd`/cache.full_img.ext4
$ sudo mount /dev/loop0 -o ext4 -o ro /tmp/mntcache
$ cp /tmp/mntcache/recovery/sec_csc.zip .
$ sudo umount /dev/loop0
$ sudo losetup -d /dev/loop0
$ unzip sec_csc.zip system/etc/autorun.iso
$ sudo losetup /dev/loop0 `pwd`/system/etc/autorun.iso
$ sudo mount -t iso9660 -o ro /dev/loop0 /tmp/mntiso
$ mkdir isocontents
$ cp -r /tmp/mntiso isocontents/
$ sudo umount /dev/loop0
$ sudo losetup -d /dev/loop0
$ echo 'cleaning up'
$ rmdir /tmp/mntcache /tmp/mntiso
$ rm sec_csc.zip cache.*.ext4 system/etc/autorun.iso
$ echo 'files are in folder isocontents'

as always YMMV.
