Bash script (Linux) to automatically decrypt the original firmware (OF) from iriver for dual-booting.

Be sure to change the two variables :

• h10 : Path to the H10 UMS mount point
• fw_orig: Name of the orignal firmware to decrypt

---

#!/bin/bash

h10=/media/H10
fw_orig=H10_Original.mi4

cd /tmp
mkdir mi4code
cd mi4code
wget http://daniel.haxx.se/sansa/mi4code.c
gcc -o mi4code mi4code.c -lgcrypt

iriver_fw=`grep -i rockbox $h10/System/$fw_orig`
if [[ "$iriver_fw" != "" ]]; then
    echo "FAILED - File $h10/System/$fw_orig is present but"
    echo "it is not orignal Iriver firmware!"
    echo "Please be sure that $h10/System/$fw_orig"
    echo "is the original (crypted) firmware"
    exit
else
    ./mi4code decrypt -s $h10/System/$fw_orig $h10/System/OF.bin
fi
