The bios update failed on my parents DV7T-4100, and now I need to recover it for them. I know you can use the method of holding the Windows Key and B for Bios Recovery but its not working on its own, and says "recovery failed." Does anyone out there have the specific files I would need to load onto a USB stick to get this thing going again, or know of another method to recover it. (Also since I am here asking, is it possible to remove/change the whitelist on this Bios for a newer wifi card) Thanks.
