lolminer dev was in a video that said it was more than likely created from the hack on nvidia. All the unlocker does is constantly refresh the count down timer the nvidia driver uses to enable LHR when it sees that GPU is mining.
I saw that video 2 days ago, whatever was the case, it was good dev miners worked hard to make the lock less effective, up to 78% was good enough given the bs nvidia imposed, in the end was just a simple unlock that somebody figured out and shared and I'm glad to whoever it was.
