Default [Q] enewman17's Tether Hack with Bluetooth enabled

I'm on MJB, rooted, but operating on MetroPCS's service. When I try to open wifi, using any app, a toast message pops up saying "Mobile data is not available or invalid SIM". I don't know if this is cos I'm on Metro or because I need to make the wifi work first, but I found @enewman17's "Tether Hack with Bluetooth enabled" from [LEAK] AT&T 4.3 UCUEMJ2 (Root & Knox versions)

Will this work on MJB as well?
