Factory Reset Green

I tried to setup my green for the first time and apparently I disconnected it too fast, because it refused to start up. (Something about a docker download). So now I am trying to do a factory reset to start the process over again. I have followed the factory reset instructions to the letter, and it just doesn’t seem to ever reinstall. I successfully flashed the version of green to a SD card, but I never get the rapidly flashing lights that the instructions say that I should get, and it never turns the lights off to show that the install is complete.

Anyone ever find a solution to this?
