In this post I aim to highlight my findings in deciding to go through the process of installing LineageOS on my Pixel 3a. Currently, LineageOS does not officially support the Pixel 3a. However, InvisibleK (Dan Pasanen) does host updated versions of his unofficial LineageOS build for the Pixel 3a complete with a custom recovery to utilize for this purpose!

Thank You
Before going on any further, I'd like to take a moment to give my sincere thanks to InvisibleK (Dan Pasanen). Having to set up the entire custom build for Pixel 3a of LineageOS myself would add far more overhead in the overall simple task in trying to get LineageOS to work on a Pixel 3a!
Preface
There are plenty of guides out there on how to install and set up ADB and
Fastboot on your host machine. For me, on Arch Linux, this was as simple as
running pacman -S android-tools. However, should you be on MacOS or Windows
you may have to find resources on how to go about this. I do not intend to go
over this here -- _sorry.
Additionally, this guide also assumes the reader has some familiarity with ADB and/or Fastboot.
Source Files
If you, the reader, knows what you're doing and simply just require the files for your Pixel 3a they can be found here:
Installation
{{< admonition warning "Warning!" >}} If it isn't abundantly clear by now, be aware that you will be destroying all the data currently on your Pixel 3a in the process of installing LineageOS on your device! Stop now and back up any files, 2FA codes, or other prior to proceeding. {{< /admonition >}}
Note about TWRP
As of writing this, TWRP1 (a custom recovery commonly used in custom OS installation) does not support Pixel 3a. However, if it does
Flash to Stock
Google is kind enough to provide a plethora of versions of the stock images for the Pixel devices. In my process of installing LineageOS, as it will be on Android 10, I made sure to flash to the latest stock version of Pixel 3a Android 10. Do note that the versions are listed in reverse order, with the latest being found in the bottom-most row.
Additionally, Google provides a helper script flash-all that I highly
recommend running as-is to flash your Pixel 3a to stock. This will take some
Flash Custom Recovery
Using InvisibleK's build page, you'll find the required custom recovery image for flashing found at the bottom of the list of zip files marked with a lone "download" link.
Download, then flash it via the following:
- Reboot to recovery
$ adb reboot bootloader - Flash the custom recovery (make sure to replace
Nwith the version you downloaded, mine was '4')$ fastboot flash boot sargo-recovery-eng-N.img - Boot the custom recovery either by re-entering recovery mode or fastboot --
make sure to wait for it to enter Android Recovery after
$ fastboot boot sargo-recovery-eng-N.img
Install LineageOS
Now that the custom recovery is set up and booted into, we're ready to install LineageOS!
- Important! Once in recovery, ensure to 'Wipe data/factory reset' prior to proceeding.
- Select 'Apply update from ADB'
- ADB Sideload the version, if not latest, of LineageOS you want for your Pixel
3a
$ adb sideload lineage-17.1-2020517-UNOFFICIAL-sargo.zip - Wait for installation to complete then select 'Reboot system now' from the recovery menu
- Enjoy LineageOS!
Verification
Once in LineageOS, you can browse the settings to verify the installation and set up Trust the preferred way. Personally, I chose to leave the defaults.
