MyBook live debricking guide osx and windows from usb

Hello dudes,

After fighting with my brick mbl for 2 day I have finally manage to debrick it.
What you need is:

  • Mac/OSX or Windows
  • 7zip
  • VirualBox
  • Ubuntu virtual machine (I use 13.10)
  • SATA HDD usb doc station (I have icy box)
1366281-a.jpg
  • Debrick script

You can download it from here
WD MyBook Live Debrick Script

or

Copy the code under and save it in a new file named "debrick.sh"

#!/bin/bash
#
# The purpose of the script is to reinstall the operating system (debrick) on 
# a harddrive that has been extracted from the housing of a WD MyBook Live.
#

#help screen
if  [ $# = 1 -a "$1" = "--help" ]; then
echo "
standard use of script is:
    sudo ./debricker.sh     the script will find out what disk to use, it will not
                            touch the partition tables and therefore perserves data.
                            it will look what the newest version of the firmware is
                            via internet and then search for it in current folder or
                            subfolders. if none is found it will download one.

possible options are:
    /dev/sd?                path to the disk from mybook live. if not given, the script 
                            will figure it out on its own.
    /*/*.img                path to the firmware that will be written to the disk. if 
                            not given, the script will search for and then download it.
    destroy                 script will rewrite the partition table of disk,
                            this will not perserve data, must match /dev/sd?.

example
    sudo ./debricker.sh /dev/sda /firmwares/mine.img destroy

  • MybookLive firmware (only the rootfs.iso file inside the archive)

Download from here MBL 2.x firmware

Step 1

Get the HDD out of the MyBook live. Here is a nice tutorial by a funny guy

Step 2

  • Install VirtualBox (download from here )
  • Download Ubuntu Desktop (here)

Step 3

Make an Ubuntu virtual machine.

Step 4

  • Start the ubuntu virtual machine
  • Install Guest Additions for the virtual machine (select the ubuntu virtual box window and Devices > Install Guest Additions)
  • Restart the virtual machine after install is done

Step 5

  • With the virtual machine open and selected plug in you USB HDD docking station (with the HDD plug in). Now the ubuntu virtual machine should tell you that an usb storage was plug in but it cant mount it (this means that everything is ok). The virtual machine needs to see the HDD if now we cant continue. If the ubuntu virtual machine is nor seeing the usb hdd you can read here how to set it up

If everything in this step works you can continue !!!

Step 6

Open Firefox in ubuntu virtual machine and download

Now Install a 7zip extractor in ubuntu. You can use Ubuntu software centre and just search for 7zip and install the only app

Step 7

With 7zip extract the rootfs.img from the MBL frimware

"Install 7zip and point it to your MyBookLive firmware "apnc-021109-053-20120413.deb" and double click and you will see "data.tar" where you will again double click and be presented with a "." Double click the "." then double click "cache volume" then double click "upgrade" and then highlight "rootfs.img" and hit extract."

After extracting the file open ubuntu terminal and install mdadm

sudo apt-get update
sudo apt-get install mdadm

For all the question asked for the install just use Yes/Ok/Continue/Default (like windows with next next next ….)

If everything in this step works you can continue !!!

Step 8

Find which dev is your usb hdd from MBL

sudo fdisk -l

A list of devices will appear. Look very carefully and be sure that you know the correct path to the usb hdd (if not you will destroy the virtual machine that is not such a big problem you can install it again or roll it back if you have snapshot)

in my case the path of the usb hdd is /dev/sdc

Step 9

Now lets debrick the hdd

cd to the place that you have download the debrick.sh file

My case

cd Downloads/

And now the magic

If you don't want to delete the data (your stuff) from the hdd

sudo bash ./debrick.sh path/to/rootfs.img /path/to/dev/mount

My case:
sudo bash ./debrick.sh rootfs.img /dev/sdc

If you want to wipe the data of the hdd

sudo bash ./debrick.sh path/to/rootfs.img /path/to/dev/mount **destroy**

Answer to all the questions from the script. And take a long nap because this thing will stay for a long time depending on how much data you have on the HDD

If everything in this step works you can continue !!!

Step 10

If everything worked fine with no errors just unmount (safe remove hard drive) the hdd, stop the usb dock power, get the hdd out of the dock and assemble back all the parts.

Plug MBL to LAN and Power and it should work like a new one

Have Fun !!
