The Samsung Galaxy Grand Quattro, as its name implies, is a device that boasts of a quad-core 1.2GHz CPU, dual SIM support, a 5MP shooter, with a 4.7-inch display and running Android 4.1.2. The device recently saw an update to version I8552XXAMH2 and if you are running this firmware and are looking to root it, the guide below is the one you should be reading.
1. This guide is only for the Samsung Galaxy Grand Quattro running the I8552XXAMH2 firmware version. Do not try this on any other device or any other firmware. If you have the older I8552XXAMDB firmware, use our guide here to help you.
2. As always, back up everything you care about from your device before you start.
3. Charge your device to 75% or more before you begin.
4. Make sure you have the necessary drivers installed before you begin. If you are not sure, install Samsung Kies that should take of care of things for you.

5. Make sure that the Re-Partition and Flash Lock are unchecked; this is important as you might brick your device if these options are ticked!

You now have a older rootable kernel and are ready to root!
1. Connect your device to your PC and copy the Framaroot-1.6.0.apk file you downloaded above to your device’s SD card.
2. Use a file manager app (Astro or ES File Explorer, for example), navigate to the location of Framaroot-1.6.0.apk, and install the application. Make sure you have enabled installation of apps from unknown sources by going to Settings > Security and ticking the Unknown sources checkbox.
3. Go to your app drawer and open up the Framaroot app.
4. Tap on Gandalf and wait for the success popup.
5. Reboot your device.
Your device is now rooted! But wait, you are still running the older kernel. Use the section below to get back to your original kernel.
Follow the same steps as in Section III, but on step #4, choose the KERNEL-INU-I8552XXAMH2-1376457550.tar file you downloaded above..
