@flohack uh-oh. Looks like I made a mistake reading the forums and purchased a pixel 5. I have had a little experience building kernels, and I also ported a root fs to cadmium linux one time. Is it possible I might try to get started poking around the device to get halium 11 working on it?

After looking at the halium docs it looked like a kernel booting through lineage was required as a starting point. I was able to see it looks like there's quite a bit of activity regarding that : https://forum.xda-developers.com/t/rom-official-redfin-lineageos-20.4217559/

Then as a next step I think I'm supposed to create a device port issue on https://github.com/Halium/projectmanagement/issues?q=is%3Aissue+is%3Aopen+pixel+5 and then try to get started with the related tasks.
