I have come across a Lenovo Y40-70 with the internal Serial/Model marked as "INVALID" in the BIOS and, while I can't verify, am having difficulties installing Windows. I've played with many tools (PhoenixTool, WinPhlash, UEFIWinflash, etc) and have seen tutorials for fixing other BIOS that have this issue, but am unable to access the DMI parameters to set them correctly. WinPhlash/UEFIWinflash gives me a "wrong BIOS" or "incorrect .bin" or some sort error when I try to access DMI settings. Other tools don't even give me the option to access DMI, or anything close to what I want.
TL;DR - how can I add/change my model name and serial into my Y40-70 BIOS?
