RE: cable modem firmware upgrade

That has been my experience as well (only from the RF side) and I would believe this was a design choice. The ISP usually wants to keep control over the firmware versions of the CM for various technical/support reasons versus having consumers mess with the firmware.

Anyone knows how to upgrade Motorola SB6120 cable modem firmware other than going through the internet provider? Your help will be appreciated.

My employer managed a handful of small DOCSIS networks for a while where 99% of the modems were Motorola, and as far as I know, there is no way to push a firmware update to the modem from the ethernet side...only from the RF side.
