Worked first go on Windows 7 64bit system with iTunes 12.0.1 (had to downgrade from 12.1 (follow the instructions to downgrade))
The whole JB time took roughly about 8-10min (phone rebooting like 4-5 times)
Stayed on 20% and 60% for quite some time.
If you see the syncing arrows on the status bar, it should be doing its magic.
