I had issues with my fingerprint reader not working. Follow the guide to install the newer fingerprint firmware, but when you get to the part about installing the cab file, if you have issues you may want boot into a root shell through recovery mode. It seems like some process is starting up and taking over the fingerprint reader preventing you from updating it. That's what worked for me anyways.
