How to officially upgrade Galaxy Nexus to Android 4.2.2

By | March 16, 2013

The Galaxy Nexus will finally get the Android Jelly Bean 4.2.2 upgrade with the ZIP file that overwrites the OS. With this upgrade the Nexus range can avail of the 4G high-speed network connectivity wherever possible. Some network providers are notorious in modifying the apps and content to make the phones more compatible, especially where there are dedicated network providers. In some places the companies have been slow to react to the changing demands of the smartphone world. Nexus is a late-comer where upgrading the operating system is concerned.

With this upgrade, Galaxy Nexus users can now look forward to some cool operational speeds and advanced applications on their mobile devices. The ZIP file is available directly from Google Market so the download and overwriting process of the OS should be a seamless effort. The update is available for Galaxy Nexus smartphone as well as Galaxy 7 and Galaxy tablets.

How to install Android Jelly Bean 4.2.2 on Galaxy Nexus

There are two ways in which you can download the OS and install it on our Nexus device. The full installation is the traditional Google Market path and the radio update uses the CDMA technology.

Direct installation

  • Download the ZIP file from Google Market on to the microSD memory card,

  • Shut down your smartphone,

  • Press the home and shutdown buttons simultaneously and the smartphone will boot in the custom recovery mode,

  • Install the ZIP file from the memory card by following the step-by-step instructions,

  • Shut the phone and reboot it.

That’s all it takes to upgrade your OS from an older version to Jelly Bean 4.2.2.

Radio flash installation

Nexus users can download the ZIP file with Code Division Multiple Access (CDMA) radio signal as well. Download the file and save it on the SD memory card as usual. To upgrade the OS follow these steps:

  • Shut your smartphone,

  • Press home and shutdown buttons together,

  • The phone will boot in the recovery mode,

  • Select the ZIP file and install it on our phone,

  • Follow the screen instructions till the process is complete,

  • Reboot the phone with the new OS.

Benefits of upgrading Galaxy Nexus with Android Jelly Bean 4.2.2

Now Nexus users have the opportunity to overwrite the operating system with the latest Android 4.2.2 Jelly Bean. This makes the mobile devices on par with other makes and models that have GSM and High Speed Packet Access (HSPA+) capabilities.

Whenever you upgrade an operating system on a device, questions about whether all the apps will function optimally are bound to raise their heads. From functionality point of view the direct installation from Google Market is always the better choice. Only if it doesn’t work for some quirky reason, then the radio installation is a better option than not upgrading at all.

It often happens that when you rush into new a version of some technology, it comes with a number of bugs that need debugging over time. But in the case of Android 4.2.2 it seems to be the opposite case. The new OS has in fact taken care of the problem that Nexus users faced when their devices rebooted without warning and for apparently no reason. This version also has some direct shortcuts to shut off Bluetooth and Wi-Fi to make the present smartphones and tablets more power efficient.
