Google has recently rolled out its latest Jelly Bean firmware - Android 4.2.2 JDQ39 - to a spate of Nexus devices including Nexus 4, Nexus 7, Nexus 10 and Galaxy Nexus I9250. The firmware update is now available for download as Over-The-Air (OTA) update for Nexus users. However, those who missed the opportunity can now download and install the same manually using this guide.

The latest OTA update Android 4.2.2 JDQ39 reportedly brings no feature updates, but only adds Bluetooth bug-fix for Android Nexus devices. Users should verify that their device is running the necessary baseband firmware, Android 4.2.2 JDQ39, before trying to install the OTA update.
