The Android Debug Bridge (ADB) is a versatile command line tool that lets you communicate with and control an Android-powered device over a USB link from a computer. It comes along with other useful tools and code bundled with the Android Software Development Kit (SDK).
May 10, 2020 The device serial number (as reported by ‘adb devices’) appears to be set in the kernel, under arch/arm/plat-s5p/devs.c (look for ‘deviceserial’). This may be different for your device, I’d suggest a grep through the kernel sources for the device ID that is reported by adb devices. Change the string, rebuild the kernel and flash it on. Aug 25, 2018 adb change device serial number. Granted, this will not be the final discussion of adb commands, but there are basic commands that everyone should know if they are planning to get dirty with the command line. After the Xposed frame is on Android, all you need is the Serial Number Changer module, which allows you to change the serial number of your Android device. Aug 24, 2017 Change the USB mode to “file transfer (MTP)” mode. Enter the following command to launch the ADB daemon: adb devices. You should now see your device’s serial number in the Terminal.
The ADB program includes three components:
- A client, which runs on your development machine. You can invoke a client from a shell by issuing an
adb
command. Other Android tools such as the ADT plugin and DDMS also create adb clients. - A server, which runs as a background process on your development machine. The server manages communication between the client and the adb daemon running on an emulator or device.
- A daemon, which runs as a background process on each emulator or device instance.
Setting Up ADB
On Windows and Linux
If you installed the Android SDK, the Android Debug Bridge will already be installed along with it. Otherwise, follow our guide on installing the Android SDK.
On Mac
If you have already downloaded the Android SDK, launch the SDK Manager by typing into a Terminal window:
<sdk>/tools/android
where
<sdk>
is the path to the tools directory. For example, if the Android SDK is located on the desktop, then you have to type into the terminal window:/Users/MyName/Desktop/android-sdk-mac_86/tools/android
As soon as the SDK Manager is launched, click “Available packages”, then “Android Repository.” When the list of available packages pops up, choose the offered revision of “Android SDK Platform-tools”. Click “Install Selected.” If it is installed, the adb executable binary will be located in the
platform-tools
subdirectory.If you don’t have the Android SDK installed yet, download its latest version and unzip it into an appropriate destination folder then follow the instructions above.
We want to make sure that ADB is now working. First, see to it that your Android device is set up for debugging. On your Android device running Gingerbread, go to the Settings > Applications > Development screen and make sure “USB Debugging” is checked. If you’re already on Ice Cream Sandwich, go to Settings > Developer options and tick “Android debugging” or “USB debugging.”
Connect your computer and Android device with a USB cable. Then, open a terminal on your computer and run the following command:
You should see something like this:
List of devices attached
XXXXXXXXXXXX device
A result like that (where the X’s represent your device’s actual serial number) confirms that your ADB is set up and working.
Learning the Codes
Now that ADB is already set up on your machine, you might want to know how to use its various flags and command options.
Flags
- -d
- directs command to the only connected USB device; returns an error if more than one USB device is present.
- -e
- directs command to the only running emulator; returns an error if more than one emulator is running.
- -s <serial number>
- directs command to the USB device or emulator with the given serial number. Overrides ANDROID_SERIAL environment variable.
- -p <product name or path>
- simple product name like ‘sooner’, or a relative/absolute path to a product out directory like ‘out/target/product/sooner’. If
-p
is not specified, the ANDROID_PRODUCT_OUT environment variable is used, which must be an absolute path. - devices
- list all connected devices
- connect <host>:<port>
- connect to a device via TCP/IP
- disconnect <host>:<port>
- disconnect from a TCP/IP device

- adb status-window
- continuously print device status for a specified device
- adb remount
- remounts the /system partition on the device read-write
- adb reboot [bootloader|recovery]
- reboots the device, optionally into the bootloader or recovery program
- adb reboot-bootloader
- reboots the device into the bootloader
- adb root
- restarts the adbd daemon with root permissions

Sync
- If <directory> is not specified, both /system and /data partitions will be updated.
- If it is “system” or “data”, only the corresponding partition is updated.
Once you already have ADB set up and functioning on your computer, you can start using it for a lot of important Android-related tasks, such as creating Android apps, debugging Android apps, and rooting your Android phone. Check out our how-to guides for rooting your Android phones.
