Great Tool! Only one little bug for me. I always get <error 199-9999> as long as my harddrive is connected / powered on. It makes no difference what kind of sigpatch (hatchi / mocca /sigpatcher /custom firmware). The only solution is to turn off harddrive... Then the installation works like a charm... Somebody else get this error ? ... update: Found a solution: After putting the installed <WUP Installer GX2 Channel> to usb, it starts !!!
