No, I did not miss that step because it is not a step. Again, you do not use adb to boot fastbootd. Please read the OP and my above post carefully. I was very precise in what I said.@Quantumstate. Thanks again for your help, but you missed the step of using ADB to issue the command "# fastboot reboot fastboot," which i did several times, if you re-read my post, but fastbootd did not launch. Perhaps I need to take the phone back to stock, which I'm not sure how to do, and reflash Havoc 3.12, 4.1, ArrowOS, or something else.
Btw I used to be in the real estate development business, also. See attached pic.
