Active Sync issue

[OZXV6700]

Id remove active sync from your PC and start again, as when you first Sync the XV to a PC it will ask will you replace the items on the desktop or on the PDA, so that may be a bit screwy.
You say it only put on 80%, does it stop after that or just say its finished?
Also try opening USB to PC in Settings>Connections and disable the advanced network functionality, as I was having a real issue getting Active Sync to work with V6 rom. Once it was disabled worked a treat.
