If you have updated your Samsung Galaxy Nexus I9250 to latest and
official Android 4.2 Jelly Bean OS, then maybe you will want to re-root
the same (or just root if your phone hasn’t been rooted until now). So,
in order to help you out with this, during the present guide we will be
checking in how to easily root the Galaxy Nexus on Android 4.2, by using
a step by step procedure designed especially for your device. You have
all the details explained below, so let’s get started.
But first we need to clear some aspects out. The most relevant thing
is related to the actual root procedure as most of the users are making
it without knowing the consequences. The root operation comes with many
advantages for your Google Nexus I9250 as the internal system will be
unchained. This means that all the factory restrictions will be removed,
so that you can obtain more control over your smartphone and over its
Android based system. In this way you can power up the performances,
improve the battery life, customize the looks and so on.
That’s why only by rooting you can apply other complex procedures,
like flashing custom ROMs firmware, or installing complex apps. Without
rooting the Galaxy Nexus you will not be able to get the CWM recovery
image, or update the system with CM10.1 or AOKP ROMs, which are well
known for the powerful and important extra features (that cannot be
found in the default version of the Android OS). As you can already
tell, when you first buy a device it will be delivered with a locked
system and it is your job to unchain the same (this can be done by
unlocking the bootloader and then by gaining root access).
Considering the up mentioned lines, by rooting the Samsung Galaxy
Nexus I9250, the warranty will get void. As you can tell, this is
happening because you are making changes into the internal system, but
if you follow my directions everything will be fine. On the other hand,
if you mess things up and somehow damage or brick the device, you will
be by yourselves. So, be careful in what you do and read twice before
applying something. For the future and as a final tip, you can restore
the lost warranty by downgrading to the stock Android Jelly Bean 4.2 OS.
Be aware as this tutorial must be performed only for those who own
the Nexus I9250 Unlocked GSM model which is on the Stock Jellybean 4.2
firmware. If you somehow complete the guide for a similar handset you
will risk in bricking it. Remember that the official Android 4.2
software must be running on your Galaxy Nexus or else the below
explained method will not work.
As this is an unofficial operation, it is strongly recommended to backup
the data first. It’s unlikely to lose something from your Nexus, but it
is better to be sure than to risk in erasing the contacts, messages,
call logs, EFS,
market apps, calendar info and who knows what else. Don’t worry because
the backup can be easily applied as there are many dedicated apps
available for free on Google Play store. In order to ease your work, you
can anytime use our backup and restore step by step guides; you can
find the same by searching through our how to section.
You will root the Google Nexus I9250 by using a Windows running
computer where you will have to download the root package. That’s why
first you need to deactivate the security programs, or the antivirus
tools. Also, if on the phone there is less than 60% power left you
should charge the battery or else the handset might get turned off while
trying to complete the tutorial. From “Settings -> Applications
-> Development -> USB debugging” you must check the last option
and you must be sure that this guide is being followed only for the
Samsung Galaxy smartphones on stock Android Jelly Bean 4.2, model number
I9250.
