Root is done, but can't get wifi tether working on stock JB 4.3 on T-Mobile. I tried both Wifi Tether Router and Wifi Treve Mod 3.3 pre, but they don't work. It seems like the issue is on the mobile hotspot installed which cannot be uninstalled on any apps: tried Titanium, Root App Delete, Root Explorer and other. Please help. ROM flash was not needed on JB 4.1.2.
