Google released Android 4.2.1 JOP40D Firmware OTA update for the Nexus 7

Today, Google pushed OTA firmware update notifications for users of Nexus 7 WiFi and 3G variants that told them that a new Android 4.2.1 Jelly Bean official build is available for their devices. At the moment this has been sent only to several countries worldwide, but the rest of them should get the notification in the next couple of days.

The Google Nexus 10 and Nexus 4 devices received the same update yesterday.

This OTA JOP40D firmware of Android 4.2.1 Jelly Bean OS has been launched and most Nexus 7 owners should apply the update right now. It was launched mostly because it fixes the December bug and with the December month being only 3 days away, the People app in Android 4.2 needed it to add birthdays and other important life and work events.

The changelog of the Android 4.2.1 OTA update contains info regarding the HID gamepad and joysticks, which ware now supported via Bluetooth. Also, bugs and some errors were fixed so that you’ll get a better Jelly Bean experience.

If you’re wondering how to update the Nexus 7 to Android 4.2.1 JOP40D Firmware then you can simply open Settings, then About tablet menu and after that you can check the ‘System updates’ section and you should see the OTA notification. Install the update and then you’re device should work even better than it did with the former Android 4.2 firmware.

It has been reported that the update notification will work only with non-rooted devices. If you’re on a rooted device, then you won’t receive the OTA update and that why you will need to restore your device to the former Android 4.2 JOP40C before installing the new JOP40D OTA firmware.

Most users who installed this new firmware on their Nexus 7 WiFi / 3G tablets noted that the performance has improved and it feels like the device UI is even smoother than before. If your device is stock ROM and it doesn’t show the OTA JOP40D firmware update, then you can use this manual installation guide here.

The update size is only 1.1MB and it doesn’t feature too many new functions, but it still should be flashed. Google should launch a major update in the next months as there are several other parts of Android 4.2.1 need to be improved and fixed.
