If that were true, then your ISP's logo would not be on the login page or anywhere else in the webpages the router serves up. The fact is that the router manufacturer writes the bulk of the software, then turns it over to the ISP to "customize" utilizing hidden features they (Verizon) asked the manufacturer to make. Verizon has backdoors built in to it's router firmware so they can push out updates to the router and set top boxes, reboot the router, remotely troubleshoot and throttle speed. Therein lies the rub, while you can try to force a manufacturer's patch onto your router, since it's running modified firmware, you may very well break it.
