Now that Nexus 5X orders are shipping out to customers, Google has posted the Android 6.0 Marshmallow factory images for the freshly-released smartphone. Of particular note is that there are 3 builds to check out here. While none of them are labeled as such, it's likely that there is a build for T-Mobile, one for Project Fi phones, and a third for every other Nexus 5X. For build numbers, you're looking at MDA89E, MDA89F, and MDA89I — but it's unclear which is which.

It's unlikely you'll be needing these so soon, given that Nexus 5X units are just starting to arrive in buyers' hands. Still, if you need to flash back to a stock build after tinkering around, you can now do so.
