Toshiba L355D-S7901 was bricked during a failed flash. I renamed the latest BIOS file to BIOS.fd and put it on a flash drive. I held down the Windows+B keys for a few seconds, plugged in the power, then held down the power button for a few seconds then let go of all three. Nothing happens. I repeated with the keys Fn+ESC and Fn+F with the same result. Tried different waiting times too. I tried an external USB floppy, the internal CD, and an external CD reader; none work. None of the devices ever spins or lights up (except the internal CD for a few seconds but it does that even with no disc). I confirmed the recovery filename should be BIOS.fd by dumping the fd file and looking at it with a hex editor. Any ideas?
