Hello! I am attempting to recovery a Dell Precision M3800 from a bad BIOS flash. I was on A10 and went to update from A11 and it locked up mid flash via the Windows Utility. I was able to extract the HDR and ROM files from the setup files and places them on a USB Flash Drive formatted FAT32. I tried a few different names, M3800.HDR/ROM, M3800A10.HDR/ROM M3800A11.HDR/ROM. No luck. I try booting up while holding CTRL and ESC and I just get a blank screen. Holding END and plugging in the power cable results in it turning on and the fans going on, and blinking power LED. However the activity LED's on my Flash Drive NEVER blink making me think it's not a naming issue. M3800 is UEFI based system. It's almost like the XPS 9530. I also tried rename the Bios EXE file to BIOS_IMG.rcv, same luck. Any help on what I should try next would be greatly appreciated.
