This is the reason why it is always recommended to take a complete device backup beforehand.

Manually doing so would take ages and also calls for a lot of effort. Therefore, the best route forward is taking a Nandroid backup directly via TWRP. Doing so will create a backup of all the partitions on your device. These include the data, system, vendor, boot, among others.

Install Android SDK

install adb platform tools windows

First and foremost, you will have to install the Android SDK Platform Tools on your PC. This is the official ADB and Fastboot binary provided by Google and is the only recommended one. So download it and then extract it to any convenient location on your PC. Doing so will give you the platform-tools folder, which will be used throughout this guide.

Boot to TWRP Recovery

  1. Now connect your device to the PC via USB cable. Make sure USB Debugging is enabled.
  2. Then head over to the platform-tools folder, type in CMD in the address bar, and hit Enter. This will launch the Command Prompt.

  3. Type in the following command in the CMD window to boot your device to TWRP
    adb reboot recovery

Create TWRP Nandroid Backup via ADB Commands

  1. Let’s now get to the crux of this article. So the general syntax to take a Nandroid Backup via ADB is as follows:
    adb backup -f <backupname> --twrp <options>
  2. Here <backupname> is the name that you want to give to the backup file. If you don’t give any name, then it would be assigned the default name backup.ab.
  3. Next comes the <options>. Here you could specify the argument as to how you would want to customize this backup. Following are the available options:
    system: backup the system partition
    cache: backup the cache partition
    data: backup the data partition
    boot: backup the boot partition
    etc: backup every partition on your device
  4. Furthermore, the backed-up file will be placed inside the same folder where we have launched the CMD window. So in our case, that would be the platform-tools folder.
  5. So if you wish to create a backup of the boot partition and name it testbackup, then the command will be:
    adb backup -f testbackup --twrp boot

  6. What if you don’t specify any argument? Well, in that case, the system and data partition will be backed up, named backup.ab. This is how the command will look like in that case:
    adb backup --twrp
  7. Furthermore, you could also add two or more arguments to a single command. For that, you just need to separate each argument by a single space. For example, if you wish to take a backup of the boot and vendor partition and name it ‘testbackup’, then the command would be as follows:
    adb backup -f testbackup --twrp boot vendor

How to Restore Nandroid Backup via TWRP

  1. Let’s suppose we have created a backup named testbackup, which is stored on our PC. We now need to restore this backup to our device.
  2. For that, boot the device to TWRP and launch the CMD window inside the platform-tools.
  3. Then, execute the below command to restore the backup:
    adb restore testbackup

That’s it. The process stands complete. And with this, we conclude the guide on how to create a TWRP Nandroid Backup directly on PC via ADB Commands.
