Before restoring Google Nexus 7 to factory state, the user data will need to back up the data and download the required files. The guide requires a certain level of command prompt knowledge and is aimed at Windows users. A 7-Zip software for extracting files from .tgz file, Android SDK along with the required Java SE development kit and Nexus 7 factory image can be downloaded from the links.
