What This Is
This is a personal project to get Lineage OS running on my Pixel 3a XL. I got the idea to build it from this thread of the Pixel 3a . It seems to suffer the same short comings of the 3a version in the link provided.
What's Been Tested
So far tested on T-Mobile (at least) with Nano OpenGAPPS and Stock OpenGAPPS. Camera, wifi, bluetooth, gps are used regularly without issue.
What Was Not Tested
eSIM doesn't work and has been removed
If flashing Gapps, an app downloaded at first-time setup Data Transfer Tools will crash constantly and needs to be uninstalled. This may mean you can't transfer data from an old phone to this one via setup.
