Unbrick then Firmware Upgrade Equals No Dashboard

@Bennor, original instruction here: https://drive.google.com/open?id=0B_6OlQ_H0PxVRXF4aFpYS2dzMEE
Use “Recovery” package for unbrick WDMC (No need to open device. An you can use it if new HDD installed.)
Or use “Replace HDD” if first method not work.

Ps: “Hand” method to reset device (After unbricking, for example):
touch /mount_point_for_md0/etc/.fresh_install
