mobile

Purchased an HTC ONE M8 TMOBILE unlocked version because I live out of the country. I use Tmobile in the USA. Everything works great with Dragonfire custom ROM except wifi and mobile hotspot. Sunshine app will not work for turning S-OFF. I am very experienced with ROMS and rooting but I cannot figure this one out. I am assuming that I have to update my firmware, but I need S OFF to do that.
