Just an update on this. My phone (a nexus 5x) went into that catastrophic bootloop, and I had to get it replaced (this is the second time I've had to do this). It was under warranty, but I lost some of the images and hald-CLUTS I had on the phone but that were not backed up. It was only a few things, but these were the ones I was preparing for the tutorial. I've just gotten my replacement phone, but haven't had time to get back set up. So, there will still be a little delay before the final tutorial and upload to the scripts repo.
