Struggling

Hi, I'm struggling running this, can anyone point me in the right direction? here's the error...

$ adb shell

shell@g3:/ $ /system/xbin/busybox nc -l -p 5555 -e /system/xbin/busybox dd if=/dev/block/mmcblk0

5 -e /system/xbin/busybox dd if=/dev/block/mmcblk0 <

dd: can't open '/dev/block/mmcblk0': Permission denied
