yes they are on the same directory if you see the terminal prompt now get another error
i run the chmod to 777 on all file and folders
dd: opening «»: dont exist file or directory
./undreamboxfs: 51: ./undreamboxfs: ./unsquashfs-lzma: not found
./undreamboxfs: 53: ./undreamboxfs: ./uncramfs: not found
cp: el objetivo «dbimage» is not a directory
Done!
