Firefox OS MultiROM build from 4th September 2014 for Nexus 5

Following this guide, I built the current (4th September 2014) Firefox OS from git repositories for Nexus 5 for MultiROM.  The guide explains how to build it, make MultiROM and how to install it on Nexus 5. The problem is that it contains build rom from June 2014. So I decided to build the current one from September 2014
