Hold Volume Down and Power until device loads into Fastboot
Might be convenient for dual boot
fastboot getvar current-slot
fastboot set_active aand

You can follow a relatively typical installation using pmbootstrap as documented here (there are no pre-built images). There are a few things to keep in mind.
If your device has Android 10 or later, you might get the following error when flashing the rootfs:
$ pmbootstrap flasher flash_rootfs Sending sparse 'system_b' 1/5 (261014 KB) OKAY [ 9.129s] Writing 'system_b' FAILED (remote: 'Partition should be flashed in fastbootd') fastboot: error: Command failed
This error occurs because Android 10 introduced dynamic partitions. There are different ways to flash the rootfs (see Different options of installation). Flashing to dynamic partitions via fastbootd is supported.
Thanks to a hack in the kernel fork, you do not need to erase the DTBO partition. Keeping the DTBO comes with a few side effects. Instead of seeing "Google Pixel 3a" as the machine name, you might see something like "Google Inc. MSM sdm670 S4 PVT v1.0". You may also see a dmesg error complaining about a ramoops reserved memory region.
If you don't like these side effects, erasing the DTBO is simple:
$ fastboot erase dtbo
Support for charging was developed by the SDM845 mainlining community, with no thermals and only 1 A.
The panel works. Note that the XL variant has 2 different panels.
This device has the FPC1020 fingerprint sensor. A driver is being worked on here but doesn't seem to be ready yet.
The Pixel 3a doesn't use SPMI haptics. Instead, it uses the TI DRV2624. The driver included in the SoC kernel works with fftest, but is in bad condition. There is no feedbackd support either.
Full-disk encryption works without 3D acceleration.
NFC card detection works. Nothing else was tested. The embedded secure element seems to have no driver support.
You don't get the same MAC address as on Android, even though it is possible to detect the MAC address that Android uses (somewhere in /sys/firmware/devicetree/base/chosen/cdt/cdb2/wlan_mac1).
It seems to be possible to initiate calls. However, this is useless because there is no call audio.
You can get audio over Bluetooth, but this isn't what the feature table entry represents. On-board speakers and the headphone jack currently don't work.
There is no flashlight support yet.
