What is ADB? ADB is short for Android Debug Bridge, a versatile command-line tool that lets you communicate with a device. It was mainly for developers to debug apps, but now basic users can also use it to perform many useful activities between computer and their Android smartphones. In this article, we are going to show you how to install ADB in Windows computer and how to use ADB to do something interesting to Android mobile phone.

Option 1. Backup and Restore Android with ADB

Backup is not necessarily the most frequently used function for Android users, but it should be the very first thing whenever we try anything new or danger. In case of accidents, a backup of mobile phone will work like a saver to our life. ADB can help you make backups for your Android smartphone with no need of root or custom recovery.

adb backup -all -f <path/filename.ab>
adb restore <path/filename.ab>
The path should be a location on your computer system drive. For example,
adb backup -all -f /Backup/backup1.ab


  • The backups are saved to computer instead of phone memory or SD card.
  • You’ll need to unlock your phone to allow the backup to start.
  • The backup mainly contains documents and media files on your phone. For a literarily full backup of phone data and whole system, refer how to make a Nandroid backup in custom recovery.

Option 2. Install APK for Android from Computer

There are already lots of methods to install apps to Android phone, including installing apk files on mobile phone, but occasionally you may need to install APK to Android phone from computer. This is especially useful if you know that the installation is completely silent with no need of operation on phone screen.

adb install <path to the apk on your computer>
The path should be a location on your computer system drive. Please move the apk file to the system drive if it is not. For example,
adb install /MyDownloads/TitaniumBackup.apk


  • No need to operate on phone screen.
  • No prompt of permissions from the app.
  • No need to enable Unknown source on mobile phone.
  • Be care of apk files containing malware.

This function may work magically when you want to install an app to your phone but unable to control the device, like due to broken or black screen.

Option 3. Reboot Phone to Recovery Mode and Bootloader

In recovery mode, people can clear cache and data, factory reset or backup mobile phone. In bootloader (or Download mode for Samsung), people can flash ROMs to handset. If you don’t know anything about recovery mode and bootloader, please make sure you know it clearly and need it first.

adb reboot recovery
adb reboot bootloader


  • No need to press key/button groups on phone body.
  • Occasionally, you may need to reboot manually or even remove battery when the command fails.
  • After every reboot, you’ll need to reconnect the phone in order to let ADB work

Option 4. Convert SD Card as Internal Storage with ADB

Since Android Marshmallow, users can format SD card as internal storage, which effectively reduces insufficient storage problem. The conversion is easy to do on Settings > Storage if your phone is supported for the feature. However, some manufacturers intentionally hide this function from users even if their smartphones have upgraded to Android 6.0 or newer. With ADB, we can convert SD card as internal storage when the option is invisible.

Warning: Please move or back up SD files card first. After the conversion, the SD card won’t be recognized by other mobile phones or computers. Once your phone is reset or dead, you may find the SD card inaccessible by any device.

  • Step 1. Launch ADB command window.
  • Step 2. Connect the phone inserted with SD card to computer.
  • Step 3. Type the following commands and hit enter after each:
    adb shell
    sm list-disks
    sm partition disk:179,64 private
  • Step 4. Go to Settings > Storage to check your storage status.

Note: If there is no change in phone storage, then you may reboot it and check the storage again.
