So, I decided to try something else to control the RGB in my PC (not for my keyboard) and used SignalRGB. But after installing it, it seems the RGB on the 80HE is impossible to control anymore, even when shutting down SignalRGB and uninstalling it will still show this error.
Not sure if this is due to a possible firmware bug in my specific keyboard, as I cannot find anyone else having this issue. Just wanted my old RGB look back 
Anyone has any clue how to possibly resolve this?
