Followed the OP's instructions and now, instead of seeing the unlocked bootloader warning when my phone boots up, there is some distorted image that is mostly teal, with some white static and smashed text near the bottom.
I was actually trying to download your PR factory image so I could extract the logo and try flashing it, but there seems to be an issue with One Drive because I can't get the download to start.

Doh! I'm an idiot. I flashed the zip instead of unzipping it and flashing the bin file.
Turns out, if you actually follow the instructions, it works

You may have flashed the file posted by respider without unzipping it first.
