When I flashed my Nexus 6P with the custom /e/project rom my phone should have then been a de-Googled phone but on every boot I was getting a “Vendor Mismatch” error which indicated I needed to flash with a later version, which I downloaded and did. I flashed to crDroid Ver 4.7.2 (Angler) which is Build # OPM7.181205.001 / Android ver 8.1.0. My “Launcher” changed to Pixel and now I have Google Play Store and services??? Under “Running Services” I now see Google Play Services!! The logo in my Task Bar is the crDroid icon so I still have lineage OS but mingled with Google stuff, even though System Info Droid says that Google Apis is “Inactive”. I have the Aurora Store but now also have the Google Play Store and so … I now have a compromise build it seems. So I’m now in a holding pattern trying to decide what’s next.
