** THIS WORKED ON MY DEVICE BUT IT MAY NOT WORK ON YOURS. APPLY AT YOUR OWN RISK **

** The following are instruction for installing Android N Preview 2 image released by Google on 4/13/2016. After the installation you will have TWRP recovery 3.0.1-0 and the data partition will be erased and unencrypted if you use method 2, which means you will have ~ 3GB more space and ~ 10 seconds faster boot speed **

Always backup your data before flashing something a total stranger gives you!

Method 1: Flash update through TWRP recovery
I will post a flashable zip shortly.

Method 2: Flash update using a computer
1- ALL of your data including the internal storage will be lost so make a backup. (If you know what you are doing and you are coming from unencrypted Marshmallow you can modify the instructions to not lose data but I won't help you with that).
2- Download this file. Note that it is NOT a flashable zip.
3- Unzip into a folder of your choice on your PC.
4- Open a command window (cmd) and cd to this directory. then run the following:

Code:

---

flash-all

---

5- Wait until prompted, then press key to reboot the phone.
6- Your data is wiped and your OS is upgraded to N with unencrypted internal storage. Your TWRP is also upgraded to 3.0.1-0.

Technical details: this is a repacking of the Google image with a modified Kernel and removed userdata and recovery images. Everything else is stock.
