Can I dirty flash nougat rom over oreo

[jacksskinz]

Hi I'm currently running the s9 port oreo rom beta 1 still
It's a bit buggy and a few bits and pieces that annoy me on it
Can I flash a custom nougat rom over it without having to wipe?

I really really cannot be bothered installing all my apps and everything again and signing in again

I'm not rooted also

I do have TWRP installed tho

no, you need to full restore with odin to go from 8 to 7, bootloader etc needs flashed, use smart switch to backup to sd card and restore back when done
