@BlindDude, @GatorsUF: It was missing the 'REGEDIT 4' header, but was otherwise valid and still successfully imported by most applications. I've corrected it.
@GatorsUF: I've been in that situation. My steps should work. Try repeating them. I updated which steps should (potentially) be rebooted after, there was a bit of an error.
Also the device may need to be unplugged from the computer. Then I send an MMS to myself and that always works as a test. Good luck. I'm very busy but I'm around.
Just FYI I'm using this ROM at the moment: Energy.HERMAN.23547.Sense2.1.Mar.19 with my procedure.
