Have the tools to restore your device to a factory state of the latest Android 4.3 build
Just as users are reporting a wide rollout of the latest Android 4.3 update, Google has posted factory images of build JWR66Y and JSS15Q for the Nexus 4, both Nexus 7's, Nexus 10 and GSM Galaxy Nexus. Factory images, if you'll recall, usually show up quickly after the announcement of a new OTA update, and are the Google-sanctioned way to restore your device to a factory state of the latest firmware version should something go wrong.
The Nexus 4, Wifi and HSPA Nexus 7 (2012), Nexus 10 and GSM Galaxy Nexus all stick with build number JWR66Y and are referred to as "android-4.3_r1.1", while the Nexus 7 (2013) splits to a different path with build number JSS15Q and "android-4.3_r2.2". Sprint and Verizon versions of the Galaxy Nexus, along with the Nexus S, are seeing no factory image changes (as expected).
If you have the need to restore your device and wanted to jump right to the latest version, you now have the tools. Those of you who are willing to flash factory images instead of wait for the OTA update can make use of this resource as well at the source link below.
