Most Android users today would definitely know the terms Rooting and ROM flashing and Nandroid. Those who constantly keep flashing their phones with new ROMS, tweaks and updates would know the importance of taking backups. While you are customizing your phone, something may go totally wrong – leaving your phone messed up. It may enter a bootloop or just may not start. Whatever the reason for this undesired behavior, your apps and data might all be lost.
Backing up the presently installed and working operating system before flashing a new ROM or tweak involves performing Nandroid. It is easy and convenient to make regular backups with Titanium Backup but it only backs up apps and data. Instead if you do a Nandroid backup of your device, you can rest assured that your entire phone is safely backed up. A point to note here is that your SD Card data is not backed up. The Nandroid backup itself is created on your SD card. Make sure you have sufficient space on your SD card to make a complete copy of your phone. Once the backup is done, manually copy it to your computer if you need it later.
What is a Nandroid backup?
A Nandroid backup is a actually a complete backup of your entire current Operating System. It backups the NAND flash, something like the hard drive of your device. A Nandroid backup can mean the difference when you install a Custom ROM or when you play with the roots of your device and something suddenly goes wrong.
You need root access to android device for this process! PROCEED WITH CAUTION!
