I just tried installing it, as our Pixel 2 died randomly yesterday. Not much luck so far, it after updating to TWRP 3.5 the install went through and it booted up. I didn't even factory reset, and the previous 7.0 data was actually still in place with apps and everything working! I decided to factory reset, and I cannot go through the setup wizard. No step auto-advanced, checking for updates is stuck for a while, but after that any option (restore or start fresh) goes to a black screen, and eveything starts crashing. I doubt this is maintained, but any ideas?
Update: Seems like you specifically have to reset and then flash the OS, that way you get a slightly different setup assistant. I am not staying on this rom however, it is really crash heavy on my device
