I finally was able to flash tne new vBIOS, but I'm not sure what actually helped. Since you mentioned HW-monitoring SW, I tried removing Speccy even though I was never running it in the background. This didn't help, so I was going through all the processes that were running in the background, but didn't find anything that I couldn't identify or would be fishy. I then went over the icons in the notification area and was checking the things running there. When I ran iCUE, I was surprised since instead of only having the option to change the settings of my keyboard, it had multiple HW-monitoring tools in it which I haven't seen before, when I was setting up my keyboard after the Win installation. I tried closing iCUE, even uninstalling it, but there were still traces of it in the system and the vBIOS wouldn't execute. I was then fed up with all of it and did a clean Win installation, just installed the basic drivers and ran the tool and viola, it worked. It flashed the vBIOS, run through and confirmed it did its thing and restarted my PC. I'm not really sure what helped, it was either that there was something corrupt on my previous installation, or iCUE was somehow blocking it, but it seems its all good now.
Thx for the food for thought again!
