Not sure I understand. Are you trying to initialize the WICED IDE/Dev Environment to its initial state, or the device itself?
To recover the device, there are instructions in the WICED Smart Quick Start Guide (SDK 2.x and TAG3 Board)
To recover the contents inside of the IDE, you could use the instructions here: How to Import a New SDK into an Existing WICED Smart IDE or try uninstalling then reinstalling?
If you prefer entering your question in a language other than English, there are some instructions here for setting this up: The Broadcom Community Forums now have language translation capabilities...

And also his/her WICED Sense needed to be recovery.
