I just had to do this on MiVB 9.x for a 6920 handset.

1. Plugged in phone and let it get an address.
2.  Logged into web portal (via IP) and logged in with default SIP Credentials
3.  Selected "Firmware Update" towards the bottom on the left.
4.  Set the filename as MINET_6920-enc.st
5.  Method is TFTP
6.  Set the IP of your MiVB instance.
7.  Click the button (I don't recall if it was "save" or "update firmware"

This was quick and did not need to do more than one TFTP transaction.
