How to Create Nandroid Backup of your Current ROM
Today we will learn how to make a Nandroid backup. I’m sure all modders/advanced users have heard of Nandroid backup, if not then in this article we will discuss how you can make a Nandroid backup and restore your data on Android devices. Every time you install a custom ROM/firmware, you must make full backup so your data stays safe and you can easily recover it if something goes wrong during the installation process.
With Nandroid backup, you can create a complete image of the Android system. With this you can completely restore your phone later. For example, if something goes wrong during flashing a firmware, your data will remain safe.
Nandroid Backup Requirements
To create a Nandroid backup of your smartphone, there are some preconditions –
- Does Nandroid backup require root access? Yes, your phone must be rooted before you continue. If you do not have root access and your smartphone is not rooted, you should use an app to backup data.
- You must have an installed custom recovery such as Clockwork Mod or TWRP.
- Because Nandroid backup saves all data as an image, it is important that you have enough memory available. It is optimal if you can insert an (empty) memory card. This means you always have the backup separately at hand.
How to Make Nandroid backup
Step 1 First of all, make sure your Android device is rooted and has an image of a custom recovery installed on it. To verify if your Android phone is rotated or not, you can download and install Root Checker app.
Step 2 Reboot your Android device and boot into recovery mode. This is normally done by pressing the Power button and the Volume down button at the same time. Especially in newer devices, the home button has to be pressed too. The phone will boot into ClockworkMod/TWRP Recovery.
Step 3 Select “Backup” option using volume buttons and confirm with the Power button.
Step 4 The Nandroid menu opens. Select the data you want to backup. “Swipe to Backup” will start the backup process. After the backup has been created, your smartphone will restart. The backup takes 10 to 40 minutes depending on the amount of memory.
Done! Now you have a Nandroid backup. So do not forget to create a Nandroid backup of your existing firmware/ROM before installing a custom ROM on your Android device.
How to Restore a Nandroid backup
Step 1 Turn off your Android device and boot into Recovery Mode.
Step 2 Now go to Restore Option. Here select the backup file that you have already saved during the backup.
Step 3 Restoring data will take some time depending on its size.
That’s all! These were the simple steps on how to back up and restore the Nandroid backup on your Android device. If you face problems/errors while creating Nandroid backup, let us know in the comments section below.
