NOTE1: The latest Auto Updates for the Toolkits include the new google files so this shouldnt be a problem for anyone who has Auto Updated their Toolkit recently.
1. Download
http://goo.im/devs/mskip/toolkit/adb_fastboot_files_for_4.2.2.zip
2. Make sure your Toolkit has been closed correctly with the "x" option in the Main Menu or the adb server will still be running
3. Extract the contents of the zip file above to your Toolkit folder (overwriting the original files)
4. Run the Toolkit and when you get to the Main Menu a popup will appear on your device asking for authentification
If you do not get a popup then unplug/replug the usb cable to redetect the device.
5. Click ok to add your pc to the accepted list
6. Select the 'Refresh Main Menu' option in the Toolkit and your device will now show as 'device' and not 'offline'
