Unbrick WD My Cloud 3TB

  1. Open the case, follow this vidoe without breaking anything, use credit cards in front on two sides, and strong knife to push from back. follow this link:

  2. Hook to a Ubunutu box via a SATA cable to retrieve data (I tried all window tools with no luck of retrieving data- v4 firmware)
  3. Download a virgin disk image (for 3TB from baidu cloud) 2TB image here: link
  4. Restore the virgin disk image you downloaded, use DISKS utility to restor the image, click on the wheel icon on top right (individual partition restore did not work for me). Use Gparted to check sd*4 is ext4 with 2.7GB in size, you can format it to ext4 if needed.



  5. Put the board back on and plugin power and ethernet cable, initialize and follow the installation instruction from a web browser.

WD My Cloud Hacking

Turn off auto update, stays with v3, NOT v4

Turn on SSH and turn off auto update and modified the file so that downgrade will be allowed. You might need to resize your My Cloud via a hard reset. May need to factory restore after -hold reset button for 10 secs, keep holding, unplug power, 30sec, plug back in, keep holding 40secs and then release.

    Hi there,

    Have you found any way to connect printers on the usb port and then share them with your network?

    Hi, it seems there are a few steps missing in between here:

    3. Set up Owncloud.
    cd /var/www/htdocs
    nano -c +146 setup-owncloud.php

    4. Create a admin user name and password.

    or I did not get it? Please advise. Thanks.

      Hi Frank,

      I’d update the firmware and use Nazar’s pre-compiled Appz. See this post.

    can you tell me which version of the WD MY CLOUD firmware you were using?
    I cannot make your guide work…
    php5-gd does not install properly for me…

    • mistan  December 30, 2015

      Hi Nano,

      I was using version 3 back then. I’d highly recommend using the new firmware and follow this post. Let me know if you need more assistance.
