All, here is the command to activate the administration menu on vendor modified firmwares such as Comcast Xfinity, Cox Homelife and ADT Pulse.

/adm/enable_ui.cgi
Response: OK

Tested on iCamera2 using multiple vendor firmware versions. Although I suspect it will work with most Sercomm models.

Credit to Prayas Kulshrestha who used the firmware mod kit on an old RC8061 image. I noticed a screenshot on page 6 of his guide that included this file in adm directory, along with some other untested commands:

@Terence, I would especially like to thank you for all of your efforts with this blog and github API list! I added this as an 'issue' to your repo. It was my first git contribution, so I apologize if the format is off. The commit process was a bit daunting for a first time user.
