How to Update Samsung Galaxy Grand 2

Samsung Galaxy Grand 2 is a great smartphone which was released this year, but unfortunately the Android 4.4.2 KitKat update is still nowhere to find. Anyway, the firmware will be rolled out soon and you will have to know how to apply the official update on your Galaxy Grand 2. In that matter, I have developed the guidelines from below. By using this tutorial you will be able to learn how to update Samsung Galaxy Grand 2 via OTA Android firmware, by using Samsung KIES, or by manually flashing the stock software. Also, I will resume the installation procedure of a custom ROM based on official Android OS, thus you are having a complex and complete update step by step tutorial.

Installing the official Android OS on your Samsung Galaxy Grand 2 represents an intuitive app to perform, especially if you are using the OTA roll out. Furthermore, by using KIES you can easily flash any Android firmware on your smartphone, though the most complex procedure is then one where Odin is being used. But, Odin is also the best way to apply when trying to unbrick the Galaxy Grand 2, therefore you should read all the guidelines from this tutorial as who knows when you will be needing this info.

As for the custom ROMs, you should know that there aren’t official update operations. So, for being able to complete the same you will have to prepare your phone first. In that matter, you will have to root your Grand 2 and install a custom recovery image on it – such as CWM or TWRP recovery. By doing so, the warranty of your device will get void, so be careful and try not to mess things up. Now, the warranty can be restore by updating with an official Android OS, so you can easily use this tutorial for updating to a custom ROM firmware, or for flashing the stock or official Android OS and for restoring the warranty and revoking root access.

Now, when updating the Galaxy Grand 2 with an official OS you shouldn’t worry about losing your data. But, in rare cases, when using Odin for installing the firmware, your data might get corrupted or wiped out, especially if in the end you will have to clear cache and make a hard reset for resolving a boot loop issue. Due to same reasons I recommend you to make a backup before going any further. Use compatible backup and restore tools from Google Play and save everything that you might need afterwards, including contacts list, call logs, text messages, EFS folder, market apps and personal info and accounts.

Odin represents an official program developed and offered by Samsung and used especially on update operations. Thus, this tutorial can be applied for both rooted and locked Android smartphones. Don’t forget that the warranty will get void if you will choose to install a custom ROM, though it can be replaced if you will use this guide for flashing the official Android OS on your Samsung Galaxy Grand 2.

In order to safely apply the guidelines from below, first you will have to prepare some things. You have to ensure that a Windows based computer can be used and that your device and its USB cable are near you – if you want to manually install the Android OS by using Odin or Samsung KIES. On the same computer you should first deactivate the security protection and on your phone you need to enable USB debugging option from path “menu –settings – developer options”. Moreover, your Galaxy Grand 2 should be charged before going any further –especially if there is less than 60% power left.

Good; now you can safely learn how to update your Samsung Galaxy Grand 2. Do note that this step by step guide is compatible only with the mentioned Android device so don’t try the steps from below in case you own a similar or different smartphone or tablet.
