Yeah, I’ve always wondered how Hank made the Meteor white. Did that mystery ever get resolved?
Yes. But imgur’s copy is out of date. I don’t know who uploaded it there, but the only places to get up-to-date info on it are the FSM thread, my site, and the firmware repository, which all have the most recent copies.

FWIW, the improved thermal regulation probably won’t step down from turbo as fast as the original D4 firmware, but it’s much smoother and more configurable and less prone to oscillating. And the UI has a whole bunch of other features the original D4 doesn’t have.
