Bios update failed. It went 100% and at the bottom said ME FW Update Failed: Internal error: FWU_Buffer. Someone else had posted this image on Dells support forum. But there system still worked after. Where mine just the fans spin black screen and the power button blinks orange with 3 long blinks and a pause. I took a pic of the spi header and there is two spi flash eeproms one is 8mb and the other is 4mb and the extracted .hdr (from update exe) is 13mb. The bios version was A11 and i was trying to update to A18 (latest) What i want to figure out is if i can somehow flash the hdr to one ot both of these flash chips or would i need to find a donor motherboard to dump the chips and clone it? Any help would be very appreciated. I have also tried numerous recovery steps like holding END key while booting up with usb stick formatted to fat32 and some other recovery tricks that dont seem to work with this model Optiplex.
