Command or script to read a binary file and skip some bytes every X bytes
You should try to use this bash script I wrote for you (require busybox on your Android):

put the script in a file called script.bash (change  with your own path) :

#!/system/xbin/bash
# sputnick 20120928 http://android.stackexchange.com/posts/30069

binfile=&lt;THE PATH OF YOUR BIN FILE&gt;
bytes=$(wc -c &lt; $binfile)
c=0 count=0

while ((count &lt; bytes - (1024+512) )); do
    dd 2&gt;/dev/null if=$binfile bs=512 count=2 skip=$c
    printf '\n\n'
    ((count += 1024+512 ))
    ((c+=3))
done


Now, in a terminal on your computer (this is for linux, adapt it if you use Windows)

adb push script.bash /mnt/sdcard/script.bash
adb shell
bash
chmod +x /mnt/sdcard/script.bash
/mnt/sdcard/script.bash


edit

This is what the script does in-fine :

dd 2&gt;/dev/null if=/tmp/bin bs=512 count=2 skip=0
dd 2&gt;/dev/null if=/tmp/bin bs=512 count=2 skip=3
dd 2&gt;/dev/null if=/tmp/bin bs=512 count=2 skip=6
dd 2&gt;/dev/null if=/tmp/bin bs=512 count=2 skip=9
