Here’s the guide for learning how to root the Samsung Galaxy Grand Quattro GT-I8552. We will also be flashing a custom recovery image during the guide which will help you flash custom ROMs. The stock recovery is nice, but you cannot flash zip files from a stock recovery. A custom recovery has many features, but the one that’s most important for new ROMs is the feature that lets us upload zip files. You do need a computer for the guide. Apart from that, you can get all the files you need after the drop.

Of course, this new rooting method only works for the Grand Quattro with model number GT-I8552. Attempting to install the files below on a different model number will probably result in a soft-brick situation. If that does happen to you, you should find the recovery mode by pressing the Volume Up + Home + Power and select wipe data/factory reset from the menu. Applying the factory reset, otherwise known as a hard reset, will get you back in normal mode without any boot loops. If you are still finding your device is not working properly, try heading over to the Sam Mobile website and download an official Android firmware build for your device. Now open Odin once again and flash that firmware build. Now your device will be running new software.
