There are a lot of threads regarding Android N but there isn't any (that I could find) which have everything you need to know, it is all spread across multiple threads so I have put them all together.

How to install Android N

First you will need to have adb set up on your computer (below)

- Automated: http://xdaforums.com/show....php?t=2588979 (follow the steps in the software)

- Manual Method:

Download this file and extract the folder called "adb" to your C: drive. Your path should look like this:

C:\adb\

You will need to open a command prompt window using this method:

- Go to the C:\adb\ folder
- hold down SHIFT key and RIGHT-CLICK
- select "Open command window here".

In order to use ADB & Fastboot from anywhere - use the following steps to setup windows environment variables:

Navigate to & click on Start > Right-Click on Computer > click on Advance System Settings >

Click on Environment Variables (under the advanced tab) > Click on New (User Variables) >

Variables Name: ADB (Or anything you want) Variables Value: ;C:\adb (this is the Path of my adb.exe file)

Mac & Linux:

Install ADB & fastboot using: this file

1. Extract the downloaded zip to your desktop

2. Open Terminal and type in:

su
cd Desktop/Android/ (note: Android is the directory extracted from zip file)

3. Now type

./ADB-Install-Mac.sh

Note: By using the method above, your adb and fastboot files are stored at this location on your Mac: /usr/bin/

Next you need to flash the image (this will wipe all data INCLUDING INTERNAL STORAGE)

Latest Android N Image (NPC56W): https://storage.googleapis.com/andr...es/preview/angler-npc56w-preview-2834ca3c.tgz

Boot into TWRP to wipe cache, dalvik, data (not internal storage/SD) and system.

Reboot to bootloader and flash the following:
fastboot flash bootloader <insert bootloader img name>
fastboot reboot-bootloader
fastboot flash radio <insert radio img name>
fastboot reboot-bootloader
fastboot flash system system.img
fastboot flash vendor vendor.img
fastboot flash boot boot.img // OR // fastboot flash boot <insert name of unecrypt boot.img>
fastboot flash cache cache.img
fastboot reboot

How to Root Android N

Prerequisites

Backup your device’s internal storage, messages, contacts, and everything else that you feel essential.

Charge your supported Nexus device to at least 60% battery level, to avoid any disturbances during the process.

Make sure that your Nexus device’s bootloader has been unlocked and ‘OEM unlocking‘ is enabled in Settings > Developer options.

Instructions

Using TWRP

Of course, you must have TWRP v3.0.0+ installed. Grab it for your device from — https://twrp.me/devices/huaweinexus6p.html And flash it using the fastboot command. If TWRP isn’t available for your device, or you have forced encryption enabled, use the CF-Auto-Root method below.

Download SuperSU v2.70 zip package: https://download.chainfire.eu/927/SuperSU/RC-SuperSU-v2.70-20160314191951.zip

Connect your Nexus to the PC via USB cable.

Now, transfer the SuperSU package to the device internal storage.

Disconnect the device and power it off completely.

Time to boot your device into TWRP recovery mode. Press and hold Volume down and Power keys until you see the bootloader mode. Once in bootloader, press the volume keys until ‘Recovery mode‘ shows up. Finally, press the power button to enter TWRP.

Now that your device has entered TWRP recovery, go to Install. Browse your internal storage and select the ‘RC-SuperSU-v2.70-20160314191951.zip‘ file. Swipe the ‘Swipe to confirm Flash‘ button.

The process will take a few seconds, and then you can tap on ‘Reboot System‘.

Using CF-Auto-Root

If the above method didn’t work for you, this might cut some slack.

Download CF-Auto-Root package: http://dl-1.va.us.xda-developers.co....zip?key=UMEs03ZOQAOFa5WZz1vQnw&ts=1458902487

Once, you have downloaded the package, extract the files to a suitable folder, using an archive manager like 7-Zip or WinRAR.

Boot your Nexus into bootloader mode — Power off the device. Now, press and hold Volume down and Power keys, until you see the bootloader screen.

When the phone/tablet is in bootloader mode, connect it to the PC using a USB cable.

Go to the folder where the files were extracted in step #2, and double-click on ‘root-windows.bat‘.

A command-line window will now open. While making sure that your device is in bootloader mode and connected to the PC, press any key on the keyboard to start the process.

Follow the instructions as stated on the command-line window. Finally, it will take a few seconds to flash, and upon finishing, your device will reboot automatically, beginning with the root procedure. During this process, your device may reboot several times.

When the device has booted up successfully, disconnect it from the PC.
