@bibz2 You can try looking for codes for a "Comcast Xfinity X1" set-top box.
The IR receiver on the Xi6 set-top box is very directional. If you think that you found what should be the right codeset but they don't seem to work, try pointing your LG remote directly at the Ignite STB.
I have an LG OLED55CX with Magic Remote. When I try to go through the Universal Remove setup and set my location "Ignite TV" is an option in the list of services. But if I choose that on the last screen for the remote setup I just get a "A temporary issue has occurred. Please try again later". No problems with Internet connectivity. TV has full access to the internet with no ports being blocked.
I'm trying to get a definitive answer on this as I see some threads that say it doesn't work, some say it does and others say it does except for the guide button.
Can the Magic Remote control the Xi6-A Ignite box?
