If you go back to stock and it starts working then it was a Kernel problem, if it still doesn't work then it's a hardware problem and there is nothing that you can do.
Actually my friend, I return to the rom sitada above, and other 2 more original versions, but without success. I believe the problem may be the same board. But okay, it was a pleasure, if you somehow get back to normal, I'll post the result here. Hugs to all!
