RE: Session times out while trying to upgrade firmware
You should be able to do an upgrading through this way in latest firmware.
The network connection will disconnect when phone reboot, your previous problem may be caused by this reason.
Now phone will fully download firmware and then reboot so it's able to do an upgrading as long as the rom file is storaged in your PC(not a FTP server or any provision server).

Regards,
James
