what year of manufacture of your laptop ? 2.13 "Readme" - To program any 2012 and newer platforms, boot to windows and run wndmifit.exe.
It looks like "HP Pavilion g6-2323sr" is a 2012th model and should be moded from DOS, but DOS-based tool which supports this model still not found. I have not seen your post about using Windows Based UEFI tool and in result have activated W7Pro Retail MSDN license. But tomorrow I'll try to check whether Wndmifit64.exe is working with this model.
