Easily Root Galaxy Grand 2 G7102 using Odin

Gaining root access on your Android device represents the first step to make when thinking in tweaking your smartphone or tablet. So, because of that you should learn how to root your Samsung Galaxy Grand 2 model number G7102. During the guidelines from below I will show you how to install a pre-rooted firmware via Odin, which means that you will be able to root your Grand 2 with ease and without using complex or risky apps or programs. So, don’t hesitate and check the lines from below for further info.

Gaining root access is therefore a recommended operation especially for the advanced Android users of Samsung Galaxy Grand 2. Of course you can root your Android smartphone for other reasons too (beside from improving the performances) as for example root access is being required when trying to install different apps from Google Play. Thus you should apply this method if you want to use your phone properly and basically for removing the factory restrictions from your Grand 2.

As you can already tell, the root operation represents an unlocking procedure. In that matter, you should know that once this guide is applied your Galaxy Grand 2 internal system will be unchained and you will be able to access the OS for making several procedures like: installing a custom recovery image (represents a link between the user and the phone’s internal system), flashing a custom kernel, updating with a custom ROM firmware, overclocking the CPU, removing in built apps, removing bloatware and lot more.

Because of that, after completing this root tutorial you will be able to customize the Android OS that is running on your Galaxy Grand 2, while on the other hand you will be able to bump the speeds, improve the performances or upgrade the battery life. Since you will be using a pre-rooted Android OS, you should know that the firmware is stable, works without issues and lags and can be easily and safely flashed for a daily use. Furthermore, with this pre-rooted software you will be able to get the latest Android features, capabilities and apps that are currently available on Google Play.

Of course, gaining root access represents an unofficial procedure, so the same has nothing to do with Samsung or with Google. By completing this guide you will make changes on the internal system of your Samsung Galaxy Grand 2, which means that the warranty of your device will get void. Unfortunately, this aspect can’t be avoided as the binary flash counter of your device will be increased. So, for restoring the Grand 2 warranty you will have to reset the flash counter – just downgrade or update to stock or official Android OS.

The pre-rooted Android firmware has been developed by third party devs – we should thank those of xda-developers because they are responsible for the present tutorial. Also, the pre-rooted firmware isn’t an official Android OS, though it is based on stock software – it is not a custom ROM either as you will get the same Android firmware as the official variant only that this OS is rooted.

Now, before heading to the proper root operation, you first have to backup the data which is saved on the internal storage memory of your Samsung Galaxy Grand 2. Even though when using Odin, which is an official program, developed and offered by Samsung, it is unlikely to lose your personal info, in rare cases the data might get corrupted or even erased. Because of that, use backup and restore apps from Google Play and save everything that you might need afterwards.

On the other hand, this is a manual root operation. For being able to complete the same you will have to use a Windows running computer, your Samsung Galaxy Grand 2 and your phone’s USB cable. Of course a connection between your computer and Android smartphone will have to be established, so because of that on your phone go to “menu – settings – developer options” and enable the USB debugging option. Also, on your computer temporarily disable the security protection and all the antivirus-like programs. At the same time check the battery status of your handset; if your device gets turned off in the middle of the root process, it might also get bricked. Therefore if there is less than 50% power left, plug in the charger before going any further.

The pre-rooted firmware can be installed via Odin by using the steps from below only on the Samsung Galaxy Grand 2 model number G7102. This step by step guide is compatible only with the mentioned Android smartphone so try not to mess things up as you can end up in bricking your Android device.
