CyanogenMod team continues to support Nexus 4 users and they are now releasing the new CM 14.1 Nougat Experimental ROM builds.
If you want to learn how to successfully flash this custom ROM on your device, then you should check the instructions listed in this article. The CM 14.1 Experimental update is based on the Android 7.1 Nougat releases, but you will find tons of extra features that will greatly improve your Nexus 4 experience.
Before starting the installation process of this new custom ROM you need to check the following guidelines:
- use this tutorial only with the Google Nexus 4 devices.
- do not attempt to update any other devices with the files that you will find in this post.
- your device has to be on a rooted firmware and it should run a TWRP Custom Recovery image.
- the custom TWRP Recovery needs to be upgraded to its latest version, so that it will support the latest Android 7.1 Nougat installation process.
- in the how-to part of this post you will find two extra preparation steps: NANDROID Backup and the Factory Reset ones.
- the NANDROID Backup process creates a full restore point for your device, one that you can use in case you end up bricking the device.
- the Factory Reset process wipes the system partition, it deletes the custom ROM and it helps your device boot the phone in normal mode.
- the Factory Reset won't delete any data from the internal storage of your process.
- in case you need to save data from installed apps, then you should use the Helium app for your device.
- use this tutorial only if you are an advanced user, we cannot be blamed in case you brick the device in the process.
- read the whole process and do not skip any steps.
- check battery life of your phone, make sure that there is at least 50% battery charge left, so that the Nexus 4 won't switch off during installation.
How to install CM 14.1 Experimental Android 7.1 ROM for Google Nexus 4:

- Move both zip files to your phone's internal storage.
- don't extract the archived contents of these files.

Use the same actions as in step 8 in order to complete Google apps installation.

These were all the steps that you had to follow in order to complete the Android 7.1 CM 14.1 ROM installation for your Nexus 4 devices.
If the installation fails you need to repeat the whole tutorial more than once. Make sure that in case you are repeating installation, then you will have to make sure that your phone meets all requirements, and that you won't be skipping any steps.
