How can I re-flash the BIOS from a non-booting machine?
I found some tricks for the Dell XPS 9350 (extracting HDR and ROM files from bios executable and plugging a USB drive) but they do not seem to apply to this laptop.
I found http://www.dell.com/support/article/uk/en/ukdhs1/SLN300716/en but I'm still unable to recover the computer. I keep getting the 3:3 blinking pattern, even after I put the latest BIOS (renamed to 'BIOS_IMG.rcv') into a newly formatted FAT32 USB stick (2 GB). I also tried with different USB sticks, and both USB ports.
