How to create a NANDroid Backup & Restore Your Entire Phone

A custom recovery is a very powerful tool. You can flash ZIPs that modify your Android device in ways in which not even root can accomplish, and in fact you'll use it to put in custom ROMs. But when you're applying all of those cool mods, there's always an opportunity that something could fail, and you would possibly even find yourself bricking your device.

But with TWRP recovery, the NANDroid backup feature makes sure that each one isn't lost, even within the bleakest situations. Once you've created a backup, you'll always have peace of mind knowing that if anything goes wrong, you'll be able to restore all of your apps and settings to working order in no time. It's something every custom recovery user should take the time to do, so I'll show you how it works below.

Creating a NANDroid Backup

First, start by booting your phone into TWRP (of course this means you'll need to have TWRP installed in the first place). This process will vary counting on your device, except for most phones, start by powering the device completely off. When the screen goes black, press and hold the quantity down and power buttons simultaneously. If that doesn't do it for you, let me know your phone model in the comments.

Within a few seconds, you'll be greeted by Android's bootloader menu (pictured below). From here, use your volume buttons to highlight the "Recovery Mode" option, then press the power button to select it.

Now, from TWRP's main menu, start by selecting the "Backup" button. After that, you see an inventory of check boxes—make sure that the "Boot," "System," and "Data" options are selected here. Finally, just swipe the slider at rock bottom of the screen to start out the backup process, which may take as long as quarter-hour . When it is done, simply click "Reboot System" to wrap things up.

At this point, you can rest a bit easier knowing that your ROM, apps, and all associated data are safely backed up (note that files saved on your SD card or internal storage aren't included within the backup). You'll want to repeat this process every so often to make sure that you simply always have a recent NANDroid backup on standby.

Restoring a NANDroid Backup

Should you ever got to fix a software problem together with your phone, your NANDroid backup is a restore point. That means that once you restore the backup, every setting, app, and Android-related file will revert to the way it had been once you made the backup.

So to repair any modding-related issues, boot your phone into TWRP, then press the "Restore" button. From here, select your backup from the list (it are going to be named supported the date it had been created), then simply swipe the slider at rock bottom of the screen. The restore process can take up to 15 minutes, but when it's done, just tap "Reboot System" and everything will be back the way it was.
