WOW!!!! Now I understand what my problems are due to!!!! I have problems with EVERYTHING on my Essential!!! From the A/B being a mess, ( continually stops booting and defaults to the bootloader after Magisk module flashing, etc) to apps not working right (Titanium Backup only backs up data), and BusyBox not installing (Viper won't work without it), and a plethora of other examples of hardware and software issues, notably the terrible audio crackle and touchscreen responsiveness. Oh, anyone know why the screen is cut off on the right side? This phone is so rough around the edges (and insides) that it's nearly impossible to like. Such a contrast to my beloved N5, which I finally sold both of (Almost 7 year old phones that can still handle ported Android updates and run BETTER than this Essential!!!

Hi Mike - I am not sure what this has to do with my question about the bootloader/vendor images people use.
However, I am using my Essential PH1 with Lineage for a loooong time and experienced only a few issues that I was able to overcome with the help of the community. I haven't had any real issue since it got official Lineage support [1] - i even dirty flashed from an unofficial build (thanks @invisiblek!) to the official build w/o real issue. (I only had to use lineage-migration-signed.zip, i believe).
If you share more details, perhaps to a relevant thread, people might be able to help you, i.e. https://forum.xda-developers.com/essential-phone/development/lineageos-16-0-appears-to-live-t3939150.
If not, then at least you have a phone that has strong support from the vendor w/ fast updates, etc.
Good luck with making your phone work!
