I succeded in flashing the custom Rom and the Kernel and everything works well and smooth, aside from a little message from an app named Mirrorlink not working... i'll read on that. The camera is back in order.No u flash it thru twrp. Just follow the instructions on superv20.
For kernel get the back to the Future version. Mk2000 bttf us996santa beta 1.
The only unresolved case is the headphone with pause, volume + - buttons and a microphone, all four of those not working at all, only the music can be heard through them.
The headphones are not the problem, they were tested on many devices even a LG G3 so I would love to do something about this
