I rooted my phone and installed fresh. I love the ability to use wireless tether. Actually that is one of the biggest reasons I rooted my phone. I installed GK and SetCPU and began having nothing but FC's and apps not running. Sprint Nav and wireless tether being the ones i need and the ones that glitch. I uninstalled setcpu and got sprint nav working but still no luck with wireless tether. Can I flash the stock kernel? if so how?
