Mine lost the WiFi so guide wasn't working at all, finally managed to reset it and get WiFi back up and running and guide works but no program info so only thing you get is whats on, no extra info at all. I guess that's better then nothing and we can use the Android TV guide for the extra info but what a bunch of BS, sell the thing, decide not to fully upgrade the guide stuff, then claim it doesn't support it.
I finally upgraded to a non DVR X1 box a while back so my 530 is in sisters bedroom not used a lot so not critical anymore but sure frustrating to know it keeps actually loosing functionality. I bought a Samsung HD QAM/OTA tuner box years ago and finally returned it just before my 30 days was up because the thing was so slow to do anything and their support was non existent.
The LG 4200a I bought worked perfectly right up to the point Comcast encrypted everything forcing me to upgrade most of my self owned and paid for QAM cable stuff.
