Before we head towards the installation guide, let’s have a recap at the Galaxy Grand 2 to give you a better idea of this device. Galaxy Grand 2 Duos was brought up by Samsung in November, 2013. The device sports a beautiful 5.25 inches TFT display with 280 ppi. There’s a 1.5 GB RAM packed inside. Powered up with 1.2 GHz Quad Core CPU accompanied by Adreno 305 GPU this device is becomes a good choice.

The upper paragraph gives you an idea about what we are going to do right now, let’s have a look on how you can unleash the power of your device using a custom recovery.

Why you should install a custom recovery? 

A custom recovery allows you to install custom roms, mods etc. Along with these, you can make a Nandroid backup, this helps you a lot as you can move back to the previous working state of your phone at any time you want if you have backed up your current system. In some cases, to root the phone you need to flash SuperSu.zip file in the custom recovery, having installed the recovery may help you while in some cases to install the recovery easily, you need to have the phone rooted. You can also wipe cache and dalvik cache of your phone using a custom recovery.

Here are the pre-installation instructions:

1. This guide is only for Samsung Galaxy Grand Duos SM-G7102!

Make sure that your device is exactly as mentioned above. To check out what device you have, go to Settings > More/General > About Device or Settings > About Device and match the model number. Be careful about the device model number, flashing a file on a device not listed here might result in bricking it up. In that case, we may not be held responsible.

2. Battery should be charged at least 60%!

Your device’s battery shouldn’t be weak. In case your device goes dead during the flashing process, your device may get soft bricked and you might be in need of flashing stock firmware and that will ultimately result in wiping up your data as well. So, make sure that you charge your device before you start the flashing process.

3. Use the OEM datacable to establish connection!

Always use the original data cable to establish connection between your Android device and your computer / laptop. Using ordinary data cables might interrupt the flashing process, so to avoid any mishap, you need to meet this requirement as well.

4. Backup everything!

Just to be on the safe side, you may consider backing up each and everything from your Android device. This is highly recommended so that in case anything goes wrong, you still have the access to all of your data and you can restore it immediately. You may backup everything as listed below.

5. Turn off Samsung Kies and other softwares while using Odin3!

Make sure that you turn off Samsung Kies while using Odin3 flashtool. Samsung Kies will interrupt Odin3 and will result in causing errors and may not let you flash your desired recovery or root file. Also, make sure that you turn off any antivirus software you’ve installed and also disable firewall to avoid any connection and flashing issues.

6. Disclaimer

The methods involved in flashing custom recoveries, roms and rooting your phone are highly custom and may result in bricking your device, and has nothing to do with Google or the device manufacturer that is SAMSUNG in our case. Also rooting your device will void its warranty and you will be no longer eligible for any kind of free device services by the manufacturers/warranty providers. In case of any mishap we may not be held responsible. Follow these instructions to the letter to avoid any mishap or bricking. Make sure that whatever you do, you are doing it at your own responsibility.
