I rooted my Moto G (Android 4.3, german) with your video and all works fine.
But just in the moment, there come a message that I could upgrade to version 4.4. This I have done. However, the update process does not work. CWM will always report that the file is not signed. If I want to install them nevertheless, it aborts with an file error. Unfortunately, my phone now reboots after each start and tried to install the update. I need help!
What can I do?
