HOW TO: Install Android 7.1.1 LineageOS 14.1 Nightly Nougat on OnePlus 3T

We have put together a detailed step-by-step instructions guide on how to install Android 7.1.1 LineageOS 14.1 Nightly Nougat custom firmware on OnePlus 3T. If you are used to installing custom ROMs on your OnePlus 3T, then this should not be any different for you.

However, for beginners, you need to root your OnePlus 3T and install a custom recovery. Please Google that up if you are unsure and make sure you read the tutorial once before actually performing it on your device.

To Remember:

  • This Android 7.1.1 LineageOS 14.1 Nightly ROM tutorial is only for OnePlus 3T (hammerhead) and I am not sure if it will work on the other variants of the OnePlus 3T on other carriers.
  • Make sure your phone has a custom recovery like TWRP installed.
  • Make a Nandroid backup of your previous phone set up before proceeding – for just in case anything goes wrong.
  • Install the Google Apps package if you want the usual Google apps (Gmail, Maps, Play Store, Calendar etc.) on your phone.

Complete Step-By-Step Instructions:

Step 1 – Download Android 7.1.1 LineageOS 14.1 Nightly ROM and Google Apps for OnePlus 3T on your PC, if you haven’t already.

Step 2 – Connect and mount your OnePlus 3T USB memory on your computer using the USB cable.

Step 3 – Now copy/paste the downloaded Android 7.1.1 ROM zip and Google Apps zip files to your internal SD card. Make sure the files are in the SD card root (not in any folder).
