This sounds horrible, I know... but I just tried to read 35 pages of different ways and updates of files, etc, and I am honestly lost.
Can someone summarize this for a n00b, please...? Or a step-by-step?
I don't want to brick anything by using an outdated method or file, or what looks to be registry or .bat adjustments, etc.

I'm not being lazy, just can't afford to make a mistake and am not confident with what I have read through.
Sincerely appreciated,
(Aura H2O with the latest stock firmware.)
