I think your files are the same as the ones already in the ROM.
What's wrong with GPS in CM10.2 or CM11 anyway? It never fails me, I always get a fix within a minute, even on a cold start.
As far as I remember GPS in CM10.1 was a little strange. I think I noticed that sometimes GPSTest was showing yellow bars but accuracy was in hundreds of feet, which actually indicated not a good lock. I may be wrong though, been a while.
