Here's how to do it manually without CASUAL. All credits to Adam.

From a computer with adb on a rooted device:

Code:
adb push aboot.img /sdcard/aboot.img

adb shell

su

dd if=/sdcard/aboot.img of=/dev/block/mmcblk0p5
Also can be done via downloading the attachment, putting at root of /sdcard/ and doing these commands in terminal on a rooted device:

Code:
su

dd if=/sdcard/aboot.img of=/dev/block/mmcblk0p5
MD5 (aboot.img) = 0ba9ad45fc15cf3d62af7dd363686b3f
