Hi, Thank you for the tip but it doesn't work, nibitor gives me error: "Cant start driver: 1275". I manage to install the nvidia drivers, with a modded INF, but the card it's not right, it looks like it's limited. I have tried to play something, and it runs but really slow... And I still can´t flash this .ROM, not with gigabyte software's, not with nvflash nor nibitor. I'm getting frustrated with this, and I can't stop feeling that it's absurde that this laptop is comptable with the 460m; 480m; 485m; 560m; 680m; etc... and not with 470m... Thank you for your help. Best regards Frankthz
