Hi I'm new to the forum. I joined because my Dell XPS 13 9333 won't boot at all, not even to bios. I've tried to flash a new bios image. First I extracted the bios image from the bios exe file using the "-writehdrfile" command and got two files named "BIOS.CAP and BIOS_BIOS.BIN". Next, I flashed it on my dell using the sequence "unplug ac, plug in usb, hold End, plug ac". When the flashing starts I get an error message after a few seconds saying: "WARNING: System PFAT was enabled. Please enter the signed image! ERROR 100 - Invalid BIOS Image!" Please please someone help me!!! I tried using Phonixtools but couldn't make it work... I just need a proper bios image to flash so I'll at least have a working bios to recover my windows. Please I am helpless, my computer is a beautifully engineered brick... I would appreciate help from anyone who thinks he knows what to do in my situation. Again, if I press the power button normally without any usb sticks (that include some type of bios image) inside I just get a black screen, nothing more.
