[ROM][(Un)OFFICIAL] LineageOS 15.1 for Nexus 6 (shamu)

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:
  1. Wipe data and do a clean install of UNOFFICIAL build
  2. 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.

Thank you for your support...

I am getting this message on every reboot https://ibb.co/gUBVux
I have downloaded N6F27M from google but there is no vendor.img in the zip file

You might want to add the info about "vendor image" + "counterfeit april fools joke" + "double tap 2 wake not working yet" + into the op under known issues or something. I see those questions posted over and over again in the old thread and other communities

People should use TWRP 3.2.1.0 with LOS 15.1

https://dl.twrp.me/shamu/

First of all, thank you very much. I'm using my Nexus 6 only as a secondary device but I'm happy to upgrade it to LineageOS 15.1 now

Does it support FBE or direct boot? I'm already running LOS 14.1 and not quite sure if encryption changes upon a data wipe

While on a phone call adding another call, then merging the two results in dropping both lines.

Install:
Wiped, lineage-15.1-20180402-nightly-shamu-signed.zip, opengapps super, magisk.

never mind

What I meant is advice people from beginning ro use 3.2.1.0 because there are in between version too.

Is the SU addon zip coming anytime soon?

You can get 'double tap to wake' working if you enable it via something like EX Kernel Manager.

Also, Magisk works great on this ROM.

someone is experiencing a problem with huge battery drain via Google Play Services?
i have clean install with full wipe (installed factory image -> twrp -> full wipe -> LOS 15.1 + OpenGapps)

and 2nd problem is strange "beep" after incoming/outgoing phone call

Running perfectly (using opengapps nano and magisk 16.1).
- Had one reboot 48hrs ago and nothing since.
- Some lag in a couple spots, but may still be settling in.
- Netflix, you have to roll back to v4.6.
- Battery drain is identical to 14.1 for me (edit: Meaning no bad drain at all...it's ideal)
- Had some minor signal issue with cell calls in spots that are normally good, but that could be weather/sunspots/aliens.
- Had no issue removing the LOScoins alert.

It's better to use Magisk on Android 8+.

Using micro, everything is working great.

Another report for all good. I upgraded from the latest 14.1 nightly: Updated TWRP; Wiped system, dalvik, cache; flashed 15.1 nightly and then mind_the_gapps; boot once, then reboot to TWRP and flash Magisk. Apps all still work; all good! Thanks for the great build!

Been using this for 2 days now. A couple of issues:

• Biggest issue is Netflix issue. Also heard YouTube TV isn't working, but I haven't had the opportunity to test it.
• Stutters when unlocking. Also when switching between apps using the multitask button (or whatever it's called).

I haven't run into any other problems (outside the ones listed in OP).

This is because DRM Widevine L1 or L3 hasn't been implemented yet. Other Oreo Roms have however. Netflix and YouTube check for this now.

Any suggested kernel for the Lineage 15.1?
My phone started stuttering (As per CPU-z it looked like two cores were offline when the battery was low) and I thought of trying PureZ Kernel 5.2, but with that my phone got stuck at the boot logo for hours. Reinstalled Lineage 15.1 to fix that and wanted to check with others before trying a new Kernel.

Do you know if there are plans to implement it?

I'm waiting for Franco Kernel. There isn't an Oreo version yet, but the dev said he intends to make a version for Lineage 15.1 Shamu on his Google + a few days ago.
