自己爱折腾，通过ssh在装软件的时候把my cloud弄砖了，估计售后也不会免费修，就自己在西数社区里面找了一下。砖的情况分两种，一种是磁盘分区都在，一种是磁盘分区都乱了。目前这两种情况救砖都需要拆开my cloud，将硬盘挂载在linux下面进行。
第一种情况，磁盘分区没有乱。（没有验证，国外说可行，而且数据不丢失）
You can write the system OS image like JRman wrote is the easiest and fastest method.
If you are a GUI guy (like me) you can write it using a GUI tool like i said in the other thread download the firmware unpack the system OS file rootfs.img and use disk utility from your ubuntu ( i did in lubuntu but it should be the same).
Download http://download.wdc.com/nas/WDMyCloud-030104-139-20131028.zip
Unzip WDMyCloud-030104-139-20131028.zip to get sq-030104-139-20131028.deb.
Unzip WDMyCloud-030104-139-20131028.zip to get data.tar.
Unzip data.tar to get a folder named CacheVolume.
Inside CacheVolume there is another folder named upgrade.
Inside upgrade there is a bunch of files the needed is rootfs.img
Open disk util in ubuntu (disk, disks, gnome-disks several names...just alt-f2 "gnome-disks) select the first raid partition in MyCloud HDD , click on the gears icon (the one in the middle of the util screen)
click on "Restore Disk Image", browse using the combobox and select rootfs.img.
Click open and finish the write process, repeat these steps with the second raid partition, close util, shutdown system, reconnect HDD to miniboard, ethernet cable to router and power supply.
If Partition layout is ok and hardware is ok this should recover a soft brick in MyCloud.
第二种情况，磁盘分区乱了。（验证，可行，要丢失数据）
下载别人提供的磁盘原镜像，在linux下，将整个镜像写入磁盘。

15 hours ago - last edited 15 hours ago Hi, dggomes & kissu,
I fixed My Cloud just now, and upgraded to the latest Firmware. Now, I am doing a Full Factory Restore.
Please forget the script and rootfs.img, see my below steps:
1. Download a virgin disk image
http://community.wd.com/t5/WD-My-Cloud/Here-is-WD-My-Cloud-2TB-virgin-disk-image/td-p/637769/highlig...
2. Restore the virgin disk image you downloaded, please follow this GUIDE, only follow the step 1 -15. If your Cloud is a 2TB disk, that's all! Or, please look forward to extend the last partition to 3 or 4TB.

3. DO NOT USE THE GParted to extend the last partition, I just follow below GUIDE. You need to modify the script to your own (# mkpart primary 9428992s -1)
http://community.wd.com/t5/My-Book-Live/GUIDE-Debrick-MyBookLive-v2-0/m-p/571579/highlight/true#M225...
That's all.
Wish everything goes well!
我是爆，感谢楼主的帖子，越来越有学术氛围了，这种感觉真不错

分享一个MC的重装系统功能，傻瓜式。是人都会，不需要linux系统。爆疯语在不在。。就是在论坛直接下载镜像，然后win下用winhex恢复到磁盘即可，恢复后开机快速恢复初始设置就行了。
