Hi everyone, four days ago I made the huge mistake of "upgrading" the BIOS of my M14xR2 from A04 to A08. Since then, I got numerous hard shutdown ( can't power on without being on AC ) while gaming on battery, which never happened before. I also got my very first BSOD since I got the machine. I read on this forum that it is possible to go back from A08 to A04 using a methode called "Blind flashing" or something like that; involving extracting the firmware onto a USB Key and booting with a certain key pressed. Could someone give me the step by step procedure as I can't seem to find it again ? Thank you very much in advance !
