Alternatively, promise ADB Driver Installer, to be the universal solution to the problem. So go to the website and click there. ADB driver installer (9.22 MByte).. Open the ZIP file and start the EXE file it contains. Confirm the UAC warning if it appears.

The appropriate ADB driver for your smartphone should now install automatically. If problems arise, you should Device administrator Open, delete existing entries with your smartphone and repeat the installation.

ADB as a download for Windows, macOS or Linux

On the developer side, Google keeps current ADB downloads under the tag platform tools Clever. There you will also find explanations of the most recent changes in ADB updates. The tools are in the packages. bad Y fast boot contain. The files are approximately 4 MB in size, saving you the overhead of the entire software development kit.

Here you can find the always up-to-date downloads of Google’s minimal ADB tools:

Linux users can also simply install ADB through their distribution’s package manager.
Mac users should read up on “homebrew” and the android-platform-tools formula.
The advantage of installing through the package manager is that packages are automatically updated and tools are defined globally.

On Windows extract the platform tools in a folder and open it. Right-click while holding down the Shift key and click “open command prompt here”.

You can also extract the zip file to any directory on Mac OS or Linux. Open a terminal window and move around with it CD in the same directory. Connect your smartphone to the computer. Now type the command in the command prompt/terminal adb devices (under Linux with sudo). Now there is the following warning on the smartphone (lower right).

after the first adb devices should be low List of connected devices the device ID with a Not authorized be recognized. After the second time, if you have allowed debugging on your PC (image above), it should device be displayed with a code. If absolutely no device appears, you may need to reinstall the missing drivers. To do this, go back up to the controller section.

BAD Commands

So now that ADB for Android is installed and running, let’s also learn and use some of the ADB commands. Before each session, it is recommended to check if ADB has correctly recognized the smartphone:

adb devices: This command gives you an overview of all devices connected to the computer with ADB support. Here you can see the device ID and status. Not authorized for example, it indicates that you must still allow the computer on the smartphone; on Linux it can also mean that you need to run the command as root or with sudo privileges. If you have multiple devices connected, you take control adb devices -l.

adb kill-server: Stop ADB on the machine. Useful for restarting the current ADB session in case of ADB problems. The counterpart, adb boot server automatically executed by ADB.

backup adb -f FullBackup.ab -apk -all: The idea here is that you make a complete backup of your application data. In practice, this turns out to be a wasted effort, as our test shows. Not all apps allow ADB backup, so you have to switch to an alternative. The save game save command is particularly useful.

adb restore backup.ab: Restore a backup.

adb reboot: This will reboot your smartphone.

adb reboot recovery: The device boots into recovery.

adb reboot bootloader: The smartphone/tablet boots into the bootloader. Once in this mode, you communicate through it. fast boot-Domain.

adb push [Verzeichnis am Computer/dateiname.endung] [Verzeichnis im Smartphone]: This command uploads a file from your computer to the smartphone.

pull adb [Verzeichnis im Smartphone/dateiname.endung] [Verzeichnis am Computer]: When you have executed this command, a file will be saved from your smartphone/tablet to PC. If the computer directory is not specified, the file ends at the path of the ADB executable or /home-Directory.

adb pull /sdcard/screenshot.png
adb shell rm /sdcard/screenshot.png:
This creates a screenshot and saves it to your computer.

adb help: Summary of all ADB commands, syntax and help.

adb sideload With this command, files such as official device updates can be installed on the smartphone; this works with Google devices and only rarely with other manufacturers. However, more complicated installations, such as custom ROMs, are done through the fast bootinterface, as we demonstrate in this example.

adb install android-app.apk: This allows you to install an Android application (APK) on your smartphone/tablet.

You can find a list of all the commands on this special page on Google!

ADB Shell: the red pill

Related to the above adb– respectively fast boot-Commands only on individual commands, the ADB shell takes you right down the rabbit hole. So just write…

  • adb shell: BYour terminal window takes you to the entry level of your smartphone. From now on, you no longer execute commands on your computer, but directly on your smartphone. The syntax and vocabulary of the commands change accordingly.

In the case of Android, these are largely commands that are familiar from the Unix world. Completing commands and names through tabs also works. Here are some ADB shell commands as examples:

  • cd/sd card move to directory SD card.
  • ls lists the contents of the current directory.
  • df-h shows the mounted partitions and their used/free space.
  • Upper part list active processes (exit with Ctrl + C).
  • mount lists existing file systems.
  • You can see the respective outputs with ” | grep [Suchbegriff]” to filter by specific terms.
  • mounted | grepf2fs about shows if and what the f2fs-format file systems are available.

Leave the adb shell again with Ctrl + C or with the command “exit”.

ADB error messages: common errors with solutions

command not found: You made a typo or the command is not yet available in your ADB version. Check the command via adb help or upgraded to a newer version of ADB.

no device: Your USB cable is not connected properly, your smartphone’s ADB interface is not active, or your smartphone is not recognized by your computer. Use a different USB port, a different cable, enable USB debugging, check the driver, restart the computer and smartphone.

The server is out of date: The ADB tools on the computer and the Android version on the smartphone must be compatible with each other. If they are not, this error occurs. Update your ADB tools.

Waiting for the device: This error is largely the same as no device. Your computer no longer recognizes the smartphone. Look above for solutions.
