Steps to install Android 7.1 CM 14.1 ROM on OnePlus 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 OnePlus 3 into recovery mode without using those key combinations.
  • As you enter into recovery, the first thing you need to do is to take a Nandroid backup.
  • After taking Nandroid backup, return to the main menu of recovery and select the Wipe option.
  • 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 Nougat based CyanogenMod 14.1 custom ROM which you’ve copied earlier and select it.
  • On the next screen just swipe to start the actual Android 7.1 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, etc.) as you’ve flashed the Cyanogenmod 14.1 ROM.
  • Do not wipe data/cache after flashing the Google Apps.
  • This completes the flashing process. Now restart your OnePlus 3 smartphone by selecting the Reboot>System option present on the recovery mode itself.
  • This first boot will take more time to start than usual. But don’t worry as after a couple of boots it’ll be normal.

Wrapping Up

Finally! Your OnePlus 3 is ready with the latest and completely stable Cyanogenmod 14.1 unofficial custom ROM based on the all-new Android 7.1 Nougat OS.
