Installing LineageOS

Overview:

Installing the OS now has 3 main parts (as far as I can tell)

1. Install recovery software - I am using TWRP
2. Install LineageOS and google apps

Steps:

Installing Recovery Software:

1. Connected nexus phone to computer and booted into fastboot mode
   Note that this seems to be a temp thing on my device

   sudo ./fastboot devices
   sudo ./fastboot flash recovery twrp-3.2.3-0-shamu.img
   

2. restart fastboot mode using reboot option then start recovery mode
3. Backup the device’s default stuff by following the instructions in TWRP

Installing LineageOS and google apps:

From the TWRP recovery screen, I followed these steps (several of these are taken directly from first reference):

1. From third link, download the lineageos file.
2. https://wiki.lineageos.org/devices/shamu/install#installing-lineageos-from-recovery

Conclusion:

I was able to successfully boot into lineageOS and the initial use appears to be many times better than the previous default installation (no more 2 second delay on typing vibrations!).
