[Nexus 6P Android Development] nathanchance:
Update for N!

Alright, first N security update. This is backwards compatible with the August patch but now that we have images, I say you should just update if you are on stock. I highly recommend checking out [MENTION=4153349]Heisenberg[/MENTION]'s guide on how to flash the images here. It is a bit of a read but it is extremely well written and will help you quite a bit if you intend to stay stock rooted. Here is how I did it:

From Marshmallow to Nougat:

Download the N factory images

Boot into TWRP

Wipe system, data, cache, and dalvik

Boot into the bootloader

Flash system, boot, bootloader, radio, and vendor

Boot into TWRP (mandatory if you want to keep TWRP)

Flash your kernel and SuperSU (optional)

Reboot

From Nougat to Nougat

Download the N factory images

Boot into the bootloader

Flash system, boot, bootloader, radio, and vendor

Boot into TWRP (mandatory if you want to keep TWRP)

Flash your kernel and SuperSU (optional)

Reboot

Download: v3.4.1 for N
