With Nexus 6P pre-orders starting to ship for some, Google has posted the Android 6.0 Marshmallow factory images for the freshly-released smartphone. For the 6P, Google has released two images. None of them are explicitly labeled, but its likely that we are looking at something for Project Fi or T-Mobile in addition to the general 6P build.

It's unlikely you'll be needing these so soon, given that Nexus 6P units are only just starting to ship. Still, if you find yourself needing to flash back to a stock build after tinkering around, you can now do so.
