How to Make a Nandroid Backup on any Samsung Galaxy S3!


You MUST have ClocworkMod Recovery already installed on your Galaxy S3. If you don't, click here on how to install ClockworkMod Recovery. 

What is a Nandroid Backup? 
A Nanadroid backup is a backup that will literally backup every single thing on your phone. It will backup your current ROM, weather it's a stock or custom rom. It will backup all your apps and app data, your current layout of your homescreen, pictures, contacts....everything! 

Why should I do a Nandroid Backup?
I recommend you always do a Nandroid backup before installing a custom ROM so during the process of installing the new custom ROM something goes wrong you can always restore back to your Nandroid backup and act like nothing ever happened to your phone.

1. Enter into ClockworkMod Recovery mode. Power off your phone.


2. Press the volume up, home center button, and power button all at the same time.


3. When you feel a vibration let go of the power but keep holding on to the volume up and home center button. 


4. Select "backup and restore". 


5. Select "backup". Now EVERYTHING is backup to your phone. If you ever run into a problems when you install a custom ROM, just revert back to this backup.
