Root the Kindle Fire 7" HD and 2 with Windows - Noob (Simple) Version

vlandreev,

Nice to have you here in our thread vlandreev, welcome. Please first take a look at this thread and fix Windows if the Path Statement is missing. Judging by the output it appears you are missing the Path of C:\Windows\System32:

Attention Windows 7 and Vista Users - Noob (Simple) Version

Once you take care of the Windows Path, then proceed to Update Java here:

Java SE Development Kit 7u13: http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html

Then test your Java here: http://www.java.com/en/download/testjava.jsp

If all is good then proceed to test the ADB Communication here:

adb kill-server
adb start-server
adb devices

If a serial number is displayed after the adb devices command, then start the Root process again by executing RunMe.bat - if you do not see a serial number after adb devices, then proceed to Re-install the ADB Driver:

We have an alternative driver here: usb_driver(Dropbox) or usb_driver(Ubuntu One)

Extract the alternative driver to your desktop and follow the install instructions at the bottom of this response

The alternative driver originates from the Android SDK and is universal for just about any Android device.

The alternative driver instructions are for Windows XP but can be used with Windows 7 and Vista.

Once we get ADB installed then let's plugin the Kindle to your computer USB to see if it initializes properly.

Once this driver has been properly installed you will see "Android Composite ADB Interface" under "Kindle Fire" in the Windows Device Manager which is located by Right Hand Mouse Click Computer, Choose Properties, then Devices or Device Manager. Expand the tree. Expand Kindle. This is where you will see "Android Composite ADB Interface".

Amazon Notes regarding this ADB Driver can be found here: Amazon ADB Notes
