title: How to build and install the latest nightly Firefox OS on Alcatel One Touch Fire?
body: <p>I want to upgrade Firefox OS 1.1 on my Alcatel One Touch Fire to the master branch (the latest revision). After having read the <a href="https://developer.mozilla.org/en-US/Firefox_OS/Building_and_installing_Firefox_OS" rel="noreferrer">Mozilla Wiki</a>, I cloned the B2G repository, built it for the <em>hamachi</em> target by typing:</p>
  
  <pre><code>./config.sh hamachi &amp;&amp; ./build.sh
  </code></pre>
  
  <p>(There are even <a href="http://b2g.vegnux.org.ve" rel="noreferrer">prebuilt images</a>)</p>
  
  <p>Now is the hardest part, since Alcatel phones are not rooted and seems to have a locked bootloader.</p>
  
  <p>The docs say that I should flash the device by typing:</p>
  
  <pre><code>./flash.sh
  </code></pre>
  
  <p>But all I get are these errors:</p>
  
  <pre><code>   adbd cannot run as root in production builds
     remount failed: Operation not permitted
     push: /home/user/B2G/objdir-gecko/dist/b2g/dictionaries/en-US.aff -&gt; /system/b2g/dictionaries/en-US.aff
     failed to copy '/home/user/B2G/objdir-gecko/dist/b2g/dictionaries/en-US.aff' to '/system/b2g/dictionaries/en-US.aff': Read-only file system
  </code></pre>
  
  <p>Could anybody write an simple step-by-step tutorial (easier than <a href="http://k.japko.eu/alcatel-otf-hackers-guide-1.html" rel="noreferrer">this</a>) on how to install the latest Firefox OS to a stock Alcatel One Touch Fire?</p>
