LineageOS is a free, community built, aftermarket firmware distribution of android, which is designed to increase performance and reliability over stock android for your device. This is a straightforward port of the device tree for flame (Pixel 4) to sunfish (Pixel 4a).

This is not a recovery-installable zip! Please read below for how to install this image
Like the TWRP build for this device, this ROM build is only known to be compatible with older firmware. I only tested QD4A.200805.003, but .001 would likely work as well. If you have a newer version, you will need to downgrade at least the bootloader and radio first. I recommend installing the QD4A.200805.003 firmware image from Google, as that's what I tested with.
1. Flash the vbmeta.img file in the included zip (fastboot flash vbmeta vbmeta.img)
2. Reboot into fastbootd (fastboot reboot fastboot)
3. Run fastboot update -w lineage_sunfish-qd3a.200805.001-v2.zip
(If you do not have a working fastbootd, extract boot.img from the update zip and flash it from the bootloader first)
- Mobile data (tested with T-Mobile only)
- Google apps (should work fine, but you never know)
