Despite the ultra-useful functionality that ADB & Fastboot impart to your computer, setting them up is pretty easy. Since they both come packaged as part of the standard Android SDK, all you need to do is download the kit and set up path variables.
Step 1: Head over to this link to download the latest version of Android SDK.
Step 2: Extract the contents of the downloaded file to your hard drive. Within the unzipped “sdk” folder, you’ll find another folder labeled ‘platform-tools’. Since we’re interested in only ADB and Fastboot, this is the one that we’re looking for.
Step 3: Move the platform-tools folder to a convenient location on your PC. The root of C: drive is usually a good idea. I also recommend renaming the folder to something easier, like C:\Android-adb.
By this point, ADB is essentially set up, but to use it, you’ll first need to navigate your command prompt window to this Android-adb folder, and then run all ADB commands inside it. Since it’s too much hassle for most users, we’ll add this location to Windows’ System Path Variable, so you can run ADB commands from anywhere.
Step 4: Right-click the Computer icon on your desktop, and go to Properties.
Step 5: Under System Properties, go to the Advanced tab, and click Environment Variables.
Step 6: The system variables are contained within the lower pane. Locate “Path” here, highlight it, and click the Edit button.
Step 7: There will already be a string of locations here; navigate to the very end, and add the following text (assuming that you have chosen C:\Android-adb as the folder; otherwise, enter whatever path you’ve located adb at):
;C:\Android-adbClick OK, finally.
