[Nexus 6  Original Android Development] dwardo:
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.

All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit our Wiki.

Important Info

DON'T USE TWRP 3.0.2-0 OR OLDER WITH LINEAGEOS. IT DOES NOT WORK CORRECTLY. USE VERSION 3.2.1.0 HERE

Current lineage 15.1 shamu nightlies are based on the N6F27M October 2017 update from google.

So you should be using the radio and bootloader img from that update.

If you already have those you don't need to flash them again.

They can be extracted from the factory image on google's site here.

Or you can use the ones linked below that I already extracted:

radio-shamu-d4.01-9625-05.45+fsg-9625-02.117.img

bootloader-shamu-moto-apq8084-72.04.img

IMPORTANT NOTE FOR VERIZON USERS: Google released a separate October 2017 security update (NGI77B) just for verizon users that has a different radio. So you'll want to flash it. I repeat, THIS RADIO IS JUST FOR VERIZON USERS.

radio-shamu-d4.01-9625-05.51+fsg-9625-02.118.img

You can use fastboot to flash the bootloader and radio.

More information and installation instructions can be found on the LineageOS wiki here.

Download Links

LineageOS OFFICIAL: https://download.lineageos.org/shamu

As you will see it is no longer available and there will be no new OFFICIAL builds as shamu has been promoted to LineageOS 18.1.

Seems an archive of the official 15.1 builds is here. To check official signature you can follow this guide

LineageOS UNOFFICIAL: lineage-15.1-20220301-UNOFFICIAL-shamu.zip

Includes the now (no longer official from now on as per comments here) non official February 2022 security bulletins.

Here is its md5sum.

Google apps: MindTheGapps or OpenGAPPS <= nano

HEADS UP:

When you initially install LineageOS, be sure you flash the gapps package with your ROM. If you boot your ROM, then go back and try to flash gapps after, you're gonna have a bad time.

If you are migrating from an OFFICIAL build to the UNOFFICIAL build you have 2 options:

Wipe data and do a clean install of UNOFFICIAL build

Dirty flash thanks to an intermediate MIGRATION build

First flash the MIGRATION build (lineage-15.1-20200501-MIGRATION-shamu.zip md5sum), boot to it and then flash the UNOFFICIAL build and boot to it.

SU addon zip: Addon Install zip / Addon Removal zip

NOTE: LineageOS does not come with root, so this is now provided for those that want it.

The install zip is a one time flash, like gapps.

Meaning, it persists when updating to a new LineageOS nightly.
