hey, thanks for your great work. I am having some difficulties with this, however. My shield just arrived in the mail yesterday, so after setting up the ADB and fast boot drivers, I use this to try and install CWM. CWM, however gave me an error with an image of a little dead Android, and the Superuser app did not appear after using it. so then, I thought perhaps I need to take the update, and then this will work. after updating, I use the utility again, and cwm still shows no command error. I'd like to root before it ceases to be an option. Any assistance would be greatly appreciated.
