How do I get wireless hotspot (tethering) working on an SGH-t999L with Andoid 4.3 LUVUBMK4
I'm gonna answer my own question here.
Apparently, something I did enabled the built in wifi tethering... before, it would fail when it attempted to validate it with T-Mobile, but now it goes through that part just fine. . When it makes the hotspots, it is named foxfisomething-or-another so foxtrot MIGHT have something to do with it, but I think it was one of the flashable zips. . When I figure it out for certain, I'll update this answer.
