This Cyanogenmod custom ROM is based on the latest Android 7.1 Nougat OS. Actually the first beta CM 14.1 ROM was released last year. But due to lot of bugs and issues, many android users turned their back towards it and preferred to go with some other unofficial custom ROMs. But as time passed by, all the bugs and issues were fixed by the Cyanogenmod team and today they have come up with a completely stable version of CM 14.1 build for OnePlus 3.

OnePlus 3 launched in last year was a very big hit due to the amazing & breath taking features that this phone had.

This Cyanogenmod 14.1 comes with some mouth watering features. One of them is split screen mode which enables you to use two apps at the same moment side by side. This features may remind you of the multi window functionality that the Samsung’s Note device had. You’ll also find few changes in the Settings menu of CM 14.1. In Settings, you can go from one setting option to another without hitting the back button which seems quite interesting. With the newly redesigned notification bar,  you get the option of direct reply on the notifications without actually launching the apps.

Procedure to install Android 7.1 CM 14.1 ROM on OnePlus 3:

Downloads:

  1. Download Android 7.1 Nougat based Cyanogenmod 14.1 ROM for OnePlus 3.
  1. Download Google Apps (Android Nougat).

Procedure:

Step 1: Download both the package files in a specific folder on your computer. Remember not to extract these zip files.

Step 2: Then connect your OnePlus 3 to your computer using original USB data cable. Copy both the zip files on your phones internal memory. After copying both the files safely disconnect your phone from computer.

Step 3: 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 Volume down key + Power button simultaneously until you land into custom recovery mode.

Method 2: Firstly enable the Developers option in Settings (refer pre-requisites). The go to Settings>Developer options> and enable Advanced Reboot option. After enabling that option, simply press 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.

Step 4: As you enter into recovery, the first thing you need to do is to take a nandroid backup. This is highly recommended as every single data present on your phone gets wiped out in the last step of this procedure. Also a complete backup can save your phone in case if it gets stuck in the process or is getting boot loops. This nandroid backup takes the backup of your entire operating system along with system data, user data, boot image, installed apps with data, contacts and even the accounts created.

Refer our detailed article for taking complete Nandroid backup / restore:

Step 5: After taking Nandroid backup, return to the main menu of recovery and select the Wipe option.

Step 6: On the next screen, tick the dalvik cache, data and cache options and swipe to start the wiping process.

Step 7: After the wiping process completes, again return to main menu and select the Install option. As you click on it, you’ll see all the files and folders present on your phones memory.

Step 8: 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.

Step 10: 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.

Step 11: Then go back and again wipe the data/cache partitions as you did earlier.

Note: This wiping data/cache step is strongly recommended in order to solve the boot loops issue.

Step 12: In the similar way flash the Google Apps package (containing Play Store, Gmail, Gtalk etc.) as you’ve flashed the Cyanogenmod 14.1 ROM.

Note: Do not wipe data/cache after flashing the Google Apps.

Step 13: This completes the flashing process. Now restart your OnePlus 3 smartphone by selecting the Reboot>System option present on the recovery mode itself.
