Hi all, I need some assistance recovering my Inspiron 7548 from a failed bios update. Currently, the system only has a blank screen and power led and battery light. I've been reading for the past few days on recovering through HDR file and END key method , but I haven't been successful in extracting the HDR file from the BIOS EXE. - writehdrfile doesn't work and /writehdrfile doesn't provide the right file from what I've read. Here are the BIOS exe's provided by Dell : A08: can't post link due to being a new member. A05: System: Dell Inspiron 7548 Any help would be greatly appreciated. Thanks.
