Need help with downgrade

[Fotzelover]

I have an att s8 plus with baseband g955usqu2cra1 and i need help downgrading back to my stock rom. This was an oreo beta that was leaked and im sick of it running bad and i cant OTA update to pie because of it.

I have been on firmware.science, but that baseband is not listed. What am i missing?

welcome to AF!!!!!!!!!!!!

is the phone rooted? if so do you have recovery? if you are rooted but no recovery i would get TWRP and make a nandroid backup and flash a new rom.

i found this on xda that might help:
