Most parts work, still not sure why Bluetooth gives me errors in dmesg, audio out works, microphone input not yet... I'm getting there.
But graphics, charging, low standby power consumption, LTE, wifi... those all work already.
The fact that postmarketOS has support and also that there are people working on mainline support, makes this a task that is not as difficult as I thought, as most work was already done for another distro.
Otherwise it runs more fluid than Android ever did on it and it has a great standby time (forgot to turn it off at around 80 % and a few days later it was at 58 %).
For now stuck on merging the Kernel patches from the sdm670-mainline project with those from Mobian, not really something I can do without knowing C. I just hope someone with the right skills does it at some point.
Then I just need to make some smaller merge requests, like one to add a udev rule for vibration support and so on.
Not much missing before I can finally use it as a daily driver.
:( now i really wish my pixel 3 wasnt bricked
Those are impossible to hard brick in my experience, you would need to break both bootloaders and recoveries. See if this helps:

Also, Pixel 3 has different hardware, but is supported by pmOS and I've spotted some commits in Mobian, so there might be people working on it there.
