I appreciate your help in community more than you can know!
One thing I’ve recently learned is that build numbers are different for each phone, and even, sometimes, for the same phone when it will be used on different carriers. There are even different builds for people who like to test things early, and for phones sold in other countries!
So the build for a Nexus 5X will be different than the build for a Pixel 2.
I was hoping to be sure the build @dana is being offered is the public release, not a developer’s build. It looks like that build number should be OPM1.171019.011.
