Recovering a faulty Dell XPS 13 9310 Bios
Here's what I did to get it back:
- Downloaded BIOS_IMG.rcv version of the 3.18.0 Bios (use the service tag to find the right version)
- Copied that to a FAT32 formatted USB-Drive
- Plugged the drive in (in my case via a USB-C mobile adapter, but that is irrelevant)
- While holding down CTRL and ESC, plugged in the power cable
I was toally amazed when the Bios recovery dialog came up! It apparently updated quite a few ROMs and left me with a responsive system.
