Rooting Process Step 1: Setup ADB

Rooting Process Step 1: Setup ADB(Credits: mrdroid)

First download the sdk zip file from here: Android SDK | Android Developers
The file you want to download will be named something like 'android-sdk_r07-windows.zip'.

Extract the zip file to your C:\ drive.
You should end up with a folder named 'android-sdk-windows'.
Open that folder and open the 'tools' folder inside of 'android-sdk-windows'. You should now be in:
C:\android-sdk-windows\tools
This is where the adb executable is located.

At this point ADB is installed and ready to go but won't be easy to use. To make it easy to use copy; we'll copy the path into the environment variables.

Find your My Computer or Computer icon and right-click and go to Properties.
In Windows 7 you want to click the 'Advanced system settings' on the left under 'Control Panel Home'.
In Windows XP you want to click on the 'Advanced' tab in the 'System Properties' window.

Click the 'Environment Variables' button.
In the bottom section named 'System Variables' scroll down until you find the Variable named 'Path'. Highlight Path and click 'Edit...'.

The Variable value: field should be highlighted. Click in the box to un-highlight the text and go to the end of that line.
Paste the following text at the end of the line. Make sure there are no spaces.

;C:\android-sdk-windows\tools\

The entire Variable value: will look something like this. No spaces!

c:\Program Files (x86)\NVIDIA  Corporation\PhysX\Common;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\android-sdk-windows\tools\

Click Ok on all the open windows.

Now go to Start > Run (XP) or Start > Search (W7) and type cmd.exe and hit enter.

Type adb

You should get a bunch of command options. If your screen displays a bunch of commands, you are good to go.
