This is a unified LineageOS 14.1 ROM that works on both the OnePlus 3 and OnePlus 3T. This ROM comes with a highly-customized kernel, as well as some other very custom modifications.

Changelogs for each update can be found in the 2nd post of this thread.

ROM features:

Based off latest LineageOS 14.1 sources (root access is

Installation instructions (for first-time installation):

First, perform a backup of your existing setup, and then perform a clean install (wipe /data and /system; TWRP is recommended). Next, try flashing the ROM and see if it installs; if it installs without any issues then congratulations! Now just flash a Google apps package, Magisk if you want root access, and then reboot.

If you get an error when trying to install the ROM ("op3.verify_modem" error), then go to the Firmware link in the Downloads section and flash the firmware package for your device. Once you flash the firmware zip file, you can install the ROM.

Installation instructions (for updating to a newer release):

If you are already running this ROM, then you can update to a newer version of the ROM via the built-in OTA updater or by simply dirty-flashing the new ROM build without wiping anything.

HOWEVER, do NOT reinstall Google Apps after installing a new update.
