Before you begin make sure you entirely read the tutorial.
1. Download Android SDK and USB drivers
Download the latest AndroidSDK from Google [1] and extract the AndroidSDK.zip file to C:\AndroidSDK.
Download and install HTC Sync from HTC [2] (HTC Sync is not required for ADB but it's the easiest way to install usb drivers).
If you are using HTC Hero and Microsoft Windows 7 (and you experience problems with driver installation) you have to follow this procedure [3] to install usb drivers and HTC Sync.
2. Set up your phone to work with ADB
Enable USB Debugging on your phone from Settings->Applications->Developers then plug the phone into your computer via USB cable (make sure the phone is turned on).
3. Check if ADB is working
Goto the Start menu and type cmd into the search bar or click Run then type in cmd to open the command prompt.
Type the following into the command prompt window ( hit enter at the end of every line):
cd\
cd AndroidSDK\tools\
adb devices
Now, you should see a serial number pop up.
[4]ADB is working as it should
This means you are all set.
If you do not see a serial number, then you need to reinstall the drivers.
