ok Now the bios has been flashed correctly with this command afudos BACKSLIC.ROM /x /p /b /n /c /reboot the slic is recognized as you can see from this screenshot and the certificate I've entered: View attachment 31271 but when I try to activate the ultimate version of windows 7 with the product key Acer I get the error message: 0xC004E003 is the first time that happens to me; all the other times I've successfully enabled.
Uninstall the Loader and, after reboot, make/upload RWE report or Slictoolkit's screens (Basic and Advanced tabs)
