Update: Just set back up from complete scratch. Wiped the slot, even followed with individual wipes including system. Re-downloaded current ROM, followed the directions to a T. Haven't added any apps at all, only my purchased key for TIBU which I haven't even run yet. Tried the "Tethering & portable hotspot". When I select Portable Wi-Fi hotspot and turn it on, it just sits "Grayed out" saying "Turning hotspot on" but never does anything. I also went into "Set up Wi-Fi hotspot" and selected "Open" Network.
Again, This is with a completely fresh install as per directions.
Any ideas?
PS: I did get my home key functionality back. :
