                    You need an external programmer, dessolder chip from motherboard and write file.

                        Depends on your skill and money to spend. For me, best is raspberry pi zero W. But for most people, it is useless because it needs too much work to set up.

                                          Peste, I need your help. Problem with HP ProBook 450 G5.
                                          I attach the broken dump. With it, the laptop does not initialize.
                                          I can't build the firmware.
