ADB & Fastboot commands are probably the most powerful commands for Android phones. ADB Fastboot commands used to control and change anything on any Android phone. If you like customization and rooting, then you must have heard of ADB & Fastboot commands, and maybe you already performed some commands for modification purposes. But there are many commands that you possibly unaware of, and so we are going to list those commands in this guide. Here you will know 50+ ADB Fastboot Commands on Android to perform through Windows, Mac, and Linux.
If you are a basic Android user and unaware of features like developer options, then you are missing many advanced features that you can get on your Android phone. As I mentioned earlier that these are powerful commands that can be used to fix, upgrade, or even unlock Android devices. Out of ADB and Fastboot, ADB is a common word, and you might also know about this word and its use. And if not, don’t worry, I will help you to understand both ADB and Fastboot in this guide along with ADB and Fastboot commands.
What is ADB?
The expansion of ADB is Android Debug Bridge, and it is used to communicate with Android devices through various commands. These commands that we use to communicate between devices are known as ADB commands. ADB feature comes by default in all Android phones but hidden deep in Settings. To use ADB commands, we need to first enable ADB support from Settings on the device. The ADB works as a client-server structure for easy communication.
What is Fastboot?
Fastboot is a bootloader mode or diagnostic tool on Android phones, which we can use to flash different files on the phone. It is a unique boot state which only supports the command line interface including reboot or restart operation. The Fastboot mode is used for any kind of modification on Android phones using Fastboot commands.
Now you must be familiar with the term ADB & Fastboot and how does it work. But still, one question remains that where we will be using these ADB & Fastboot commands. And so, we have a dedicated section below for the same. Let’s check out the usage of these commands.
What are ADB and Fastboot Commands?
ADB & Fastboot commands have different functions and effects on Android phones. Let’s first understand ADB Commands. These commands are used to communicate with devices like booting devices into different modes, installing & uninstalling Apps, and also checking connectivity.
Fastboot commands are used to add additional functionality or features to devices. These features include flashing various files like custom recovery, Magisk, and other image files. Fastboot commands work only when the device is in the specific bootloader state.
Note:- To use ADB & Fastboot commands, the device should be connected to the computer. And also, drivers are required. So before using ADB & Fastboot commands, make sure to install ADB & Fastboot drivers on your computer. The driver may not be necessary in the case of the Mac and Linux operating systems, so you can skip installing the driver. For Mac and Linux you can use Platform tools.
Important tools for ADB & Fastboot:
- Install ADB & Fastboot Driver – (Windows)
- Platform Tools for Windows (v31.0.2)
- Platform Tools for Mac (v31.0.2)
- Platform Tools for Linux (v31.0.2)
Also, for using ADB commands, the USB debugging must be enabled on your phone. So let first check out the method to enable USB debugging.
How to Enable USB Debugging on Android Phones
- First, open Settings on your Android phone.
- In Settings, look for About phone and open it. It can be inside some different settings in different brand devices. So searching About Phone is a good move.
- Now, in the About Phone, repeatedly click about 7-8 times on the Build Number. It should display, ‘Now you are a Developer.’
- Go back to the main Settings and search for ‘Developer Options.’
- Open the Developer Options from the search results and search for USB debugging.
- Enable the USB Debugging Option.
- That’s all, and now you can connect your phone to the computer and use ADB commands.
Now you can easily use ADB commands. But for Fastboot Commands first, you have to boot your phone into Bootloader mode/Fastboot mode. You can use the key combination to boot your phone into this state. The key combination can vary according to the device you are using. There is also a common method to boot any phone into Bootloader, which is possible using ADB Command that you will know in the below list of ADB Fastboot Commands.
ADB Commands for Windows, Mac, & Linux
- adb devices – This is the basic adb command that used to list all the devices connected to the computer, and debugging is enabled. If you are entering the ADB command for the first time, then it will prompt to allow debugging on your phone. So you must allow it to use ADB commands to your phone.
- adb reboot – You can use this command to reboot your phone without using the power button. It can be used when any modification requires a reboot.
- adb reboot bootloader – As you know, to use fastboot commands, you have to boot your device into bootloader/fastboot/download mode. So this is the command that will boot your device into the Fastboot mode. After this adb command, you can use any fastboot command to modify your device.
- adb reboot recovery – With this command, you can boot your Android phone to the stock recovery or custom recovery. You can also boot your phone into recovery using key combinations, but that is more complicated as the combination varies as per devices.
- adb shell – The shell command will enable the Linux terminal interface on your command window to control your connected Android phone. It allows us to enter Linux commands to interact with the device.
- adb install <file path> – This command is for installing apps on the phone directly through the computer. Here <file path> means the location and name of the APK. So after adb install, just drag and drop the apk file, and it will pick the location and file name.

This is a helpful command if you want to remove bloatware or pre-installed apps.
- adb shell pm uninstall com.example.myapp – To uninstall any app while keeping its data and cache in the storage.
- adb clear com.example.myapp – It will remove all the data and cache related to the package.

Make sure to replace <screenrecord location> with the location & extension where you want to save the screen recording file. For eg. /storage/emulated/0/Download/screenrecord.mp4. To stop screen recording, press Ctrl+C.
- adb push <file source> <file destination> – The adb command used to copy the <file source> from your computer to the <file destination> on your phone. It can be used if you want to transfer any file from the phone without drag and drop. Replace <file source> with file directory where your file is existing and <file destination> with the location where you want to save the file.

So there you have it the complete list of ADB & Fastboot commands for Windows, Mac, & Linux operating system. There are more ADB Fastboot commands that generally used by recognized developers for development and testing purposes. In case if you have any queries or any problem with the given ADB Fastboot commands then let us know in the comment section.
