Default twrp bootloop newb and have no idea

I have an lg g2 d802 32gb and rooted it easily enough when I got it the wanted to put a kit kat image on it so put twrp recovery on there and then moved the rom onto the sd card and was following the process to flash but couldn't find the zip on twrp so i thought maybe I had put it in the wrong. I then tried to reboot the phone from twrp and it won't load up. I can back to twrp by pressing volume and down but cant get it back on.

Please, please help me

Regards
