Update Nexus 7 with Android 4.2.2 JDQ39 OTA Official Firmware

The third Google Nexus device to receive an update to Android 4.2.2 via JDQ39 OTA Official Firmware is the manufacturer’s Nexus 7 model.

This tool that we will teach you how to install was created so that problems such as bugs present on the earlier update could go away. And they did, as we soon found out from previous updates for Google Nexus 4 and Nexus GT-I9250.


We will not let you proceed to our tutorial unless you see whether or not your Google Nexus 7 features Android 4.2.1 JOP40D software (it’s in the “About phone” option). As soon as you find out that the software really is on the gadget, then you should also check if it is factory unlocked and if USB Debugging is turned on (if not, do it yourself). Then you need to make backups for your apps and your APN settings, sync your contacts, charge the battery in use and install the right drivers for the device (on your computer).Nexus-7
