As I mention in the previous post, BINX is the safest way to upgrade your VEGA device to a completely new generation of Android (ICS to Jelly Bean, Jelly Bean to KitKat).
if you have a slow internet connection, you better download BINX file separately and put into the temp folder then follow then method described in Step 7 of this post.
Here are the link for the latest KitKat firmware (as of September 2014) for Pantech VEGA No. 6
