Using own Bootstrap 3 files
I've had success utilizing the Bootstrap Library module. 


  This module loads via libraries the Bootstrap files installed on /sites/all/libraries/bootstrap, regardless of the theme you are using. It does nothing else.
  
  When using Bootstrap themes is particularly helpful to:
  
  
  Correct Browser Support issues, installing respond.js. 
  Update your Bootstrap version over your current theme options. 
  Just to avoid CDN files loading.
