Steps to install Android 7.1.1 LineageOS 14.1 on One Plus 3

  • Download both the package files in a specific folder on your computer. Remember not to extract these zip files.
  • Then connect your OnePlus 3 to your computer using the original USB data cable.
  • Copy both the zip files on your phone’s internal memory.
  • After copying both the files safely disconnect your phone from the computer.
  • Next, you need to boot your OnePlus 3 into TWRP (or CWM) custom recovery mode.
  • There are actually two different methods for doing that. You may use any one of them:
  • Method 1: Power off your device completely. Then press and hold the Volume down key + Power button simultaneously until you land into custom recovery mode.
  • Method 2: Firstly enable the Developers option in Settings. Then go to Settings>Developer options> and enable the Advanced Reboot option. After enabling that option, simply press the power button to pop up the typical power menu. Then tap on the Reboot option and next select the Recovery mode option. This will directly boot your One Plus 3 into recovery mode without using those key combinations.
  • At first, you need to do is to take a Nandroid backup.
  • On the next screen, tick the Dalvik cache, data, and cache options and swipe to start the wiping process.
  • This step will clear all the data present on your internal memory so make sure you’ve backed up everything before implementing this step.
  • After the wiping process completes, again return to the main menu and select the Install option.
  • As you click on it, you’ll see all the files and folders present on your phone’s memory.
  • Just navigate to the Android 7.1.1 Nougat based Lineage OS custom ROM which you’ve copied earlier and select it.
  • On the next screen just swipe to start the actual Android 7.1.1 Nougat custom ROM flashing process.
  • Be patient and wait a few minutes until the flashing process completes successfully.
  • As soon as it completes, a successful message will appear on the screen.
  • Then go back and again wipe the data/cache partitions as you did earlier.
  • Similarly flash the Google Apps package (containing Play Store, Gmail, Gtalk etc.) as you’ve flashed the Lineage OS ROM.
  • Do not wipe data/cache after flashing the Google Apps.
  • The flashing process completes here. Now restart your One Plus 3 smartphone by selecting the Reboot -> System option present on the recovery mode itself.
  • This first boot might take more time to start than usual. But don’t worry as after a couple of boots it’ll be normal.
