If you had a working hardware configuration before updating, then I can’t imagine why the latest software wouldn’t work. Therefore, I recommend using a new Raspbian image for your Raspberry Pi and following the instructions for 2.1.4 installation. Let us know if this works and if not what specific error so we can troubleshoot.
