P9 Lite Stock rom

I recently rooted my p9l using twrp, but then i got that error "getting package info failed". Some1 fixed it for mr, but i want to try again. I heard you had to flash stock. Im at b130 right now and i would like to know is there is a way to flash stock using twrp and where to download stock. Could some1 help me out? :/
Btw im onVNS-l21
