LineageOS Oreo on HTC 10

Android Nougat was giving me grief today so I switched to Oreo:

1. Use fastboot to install latest TWRP recovery
2. Use fastboot to install Oreo firmware (I used the first Verizon link)
3. Use TWRP recovery to install UNOFFICIAL LineageOS 15.1*, micro OpenGapps for ARM64, and Magisk
4. Verify phone boots normally and install substratum and Default Dark Theme

* Note: I initially got an E3004 error so I had to manually delete the assert check to get it to install on my device.

Issues:

• So far, my only major issue is no subwoofer/boom speaker (fixed with this zip installed from recovery) and poor battery life (which the Naptime app solved).

Next challenge: install Android Pie
