DISCLAIMER:

Installing a custom ROM may require the bootloader to be unlocked on the phone, which may VOID your warranty and may delete all your data. Before proceeding further you may consider backup all data on the phone. You are the only person making changes to your phone and I cannot be held responsible for the mistakes done by you.

Points to NOTE:
– Try to avoid restoring apps backup using Titanium Backup. It may break things up.
– Don’t restore system data using Titanium Backup! It will definitely break the current installation.

Upgrading from earlier version of OFFICIAL LineageOS 14.1 or LineageOS 15.1 for Nexus 6 (shamu):
If you are on an OFFICIAL LineageOS 14.1 (yes, I mean the Android Nougat based OFFICIAL LineageOS 14.1) then you don’t need to wipe the data and you can upgrade to the OFFICIAL LineageOS 15.1 just by cleaning the system partition.
- Copy the latest LineageOS 15.1 for Nexus 6 ZIP file, Oreo 8.1 GApps and/or supersu ROOT package to the phone or use the updater app to download the LineageOS 15.1.
  NOTE:
  – If you are on an OFFICIAL LineageOS 14.1 then you will be allowed to download the latest OFFICIAL LineageOS 15.1 using the updater app but you won’t be allowed to upgrade to LineageOS 15.1 on top of LineageOS 14.1
  – So, you need to export the downloaded LineageOS 15.1 ROM build file to the SD card or phone memory from the updater app:
  You can export the downloaded package to the sdcard/phone memory from the Updater app by long-pressing the downloaded file and then selecting “Export” on the top menu
- Boot into Recovery.
  – Make sure you have a latest custom Recovery that should be able to flash the LineageOS 15.1 ROM update.
- Format or wipe the system partition from the custom recovery menu.
- First install the OFFICIAL LineageOS 15.1 ROM ZIP file from device. DON’T REBOOT YET. Then flash the GApps and/or supersu zip from your device memory WITHOUT rebooting.
  – Here is a post explaining how to install LineageOS
  – Here is a post explaining how to flash GApps using TWRP recovery.
  – Here is a post explaining How to Enable ROOT for LineageOS 15.1 ROM

[blockquote]OFFICIAL LineageOS 15.1 for Nexus 6 (shamu) is now available to download on the OFFICIAL LineageOS website.[/blockquote]
Hi. I do not yet see a LineageOS 15.1 build available for download in the [url =”https://download.lineageos.org/shamu”%5Dlist of official Nexus 6 (shamu) builds[/url]. Also, not yet available for download using the updater app from the LineageOS 14.1 shamu build. Am I looking in the wrong place? I’m looking forward to trying it out.

The 15.1 build is now available in the [url =”https://download.lineageos.org/shamu”%5Dlist of official Nexus 6 (shamu) builds[/url].
I installed 15.1, along with the “mini” version of GApps. A couple things I encountered in case they are of help to anybody:
Make sure you have a very recent custom recovery version on your phone. I thought TWRP 3.0.3.0 from last December would be recent enough. It wasn’t. When I attempted to flash the 15.1 build it kept throwing errors and failed no matter what options I chose. I upgraded to the latest TWRP 3.2.1-0 image and the flash succeeded, albeit only after I disabled ZIP verification.
I’ve run into some issues with the new build. At every startup, a warning message is thrown:
“Android System A vendor image mismatch has been detected…”
A nuisance, but not a big deal
The bigger issue with this build on my Nexus 6 is that Privacy Guard pops up and either locks up the phone making it completely unresponsive or causes spontaneous reboots. This is the most serious issue I’ve encountered, and if I cannot resolve it, I may need to revert to a 14.1 build.
Also, the version of Gmail that comes with the 15.1 GApps (I used OFFICIAL Oreo 8.1 Mini GApps Download link for ARM 32-bit Android) has a pop-up that appears on my Exchange account every time I open the Gmail app. It cannot be suppressed no matter what option is chosen within the Gmail app, or notification settings.
Others have [url =”https://productforums.google.com/forum/#!topic/nexus/a3U5yTMLXjE”%5Dreported this issue[/url] and I’ve seen no reported solution, other than abandoning Gmail as the mail app.
