Can you get into recovery? Power vol- button combo? If so just flash correct kernel version n good to go.
I can't! That's where I'm trying to get to, my TWRP has disappeared. I think that when I did the KDZ flash that it wiped it out. I can do a factory reset, but that doesn't help me at all. I have been looking for a way to install TWRP via USB but no luck so far, can't connect to wifi and the phone power cycles after 1-5 minutes.
