Apparently there are a few guys who say that they have a 100% solution for the fix.
The Neosaic team used the Matrix fixes to create they're own or something of the sort. Result is the Neo-Fix Xii

The Ripper Team has a few potential fixes for the problem based on the vandrunen fix.

Also apparently Foundmy has released a fix for the v12. Then there's the Matrix PIC fix... the diode fix....etc. I have no idea about what the hell all of this does..... I haven't really been following, too much work to get the v12 to work properly. Glad I got my v7
. Good luck though.
