How To Make A Complete Nandroid Backup of an Android Phone

Basically, this so-called Nandroid backup can save you a lot of trouble in case you soft-brick your device. In just a few clicks, your whole system is restored and your device is fully functioning again, as if nothing ever happened. In this short guide, I’ll give you the simple steps so that you can make a backup yourself to be on the safe side. I’ll also show you how you can transfer your backup to your computer so that you don’t need to keep it on your device to save space.

How to do a Nandroid backup

1. Prerequisites

In order to be able to make a Nandroid backup, your Android device has to be rooted and needs to have a custom recovery tool. 

If your phone is not rooted and still you want to backup your phone then follow our guide here.

2. Go into recovery

To get into your recovery, you first need to boot your device into the bootloader. With many devices, this can be done by turning it on holding down the volume-down and power button. However, since it depends on what device you have.

Once you managed that, simply navigate with your volume buttons to “Recovery mode” and select this option. Now your device will reboot into your custom recovery.

3. Do the nandroid backup

Once you’re inside the recovery it’s a piece of cake, no matter if you’re using ClockWorkMod or TWRP as recovery. Here are the two different, yet similar ways to go from here:

TWRP:

• Go to “Backup”
• Choose the partitions you want to back up. If you’re not sure what to choose, simply leave the default selections.
• Make the backup by swiping to the right at the bottom.
• Your device should now perform the backup process, once that’s done you can reboot your device.

CWM:

• Go to “Backup and restore”
• Choose “Backup”
• Your device should perform the backup now
• After successful completion, select “Go back” and choose “Reboot system now” to reboot your device.

4. Transfer the Nandroid Backup to a computer

Now, depending on how many apps and files you installed, your backup might take away quite some space. To avoid that, you can transfer the whole Nandroid backup to your computer and delete it on your device. Should you ever need to restore your device, you only need to transfer it back.

TWRP:

Connect your device to your computer and go to the TWRP folder on your device. In there, a folder containing your backup can be found. If you have several on your device, they will be separated so that you can choose only the folder you need. After you successfully copied the folder, you can delete the one on your device.

CWM:

The approach is the same as above. The location of CWM backups are usually located in /data/media/clockworkmod/backups. This means the data folder situated in the root folder, not the sdcard folder. People have been reporting that they were not able to “see” the backup files and, therefore, not able to copy them. One approach is to use your favorite Android file explorer app and copy the backup folder to another one such as your camera folder “DCIM”. Now, check this folder using your computer to see if the backup is visible.

5. Restore your device using your Nandroid backup

That’s an easy one as well. Simply boot into recovery, select “Backup” or “Backup and restore” in CWM and choose the restore option. Now you can choose the backup you want to use and restore your device. Once that’s finished, reboot your device and you’re done!
