            Hi everyone, I had the same problem with the endpoint controller.
            It rarely turned on, and the last time I was able to update the BIOS correctly.
            After restoring the default settings, the screen stays off and the Caps Lock LED blinks 7 times.
            I can no longer get it to start in any way.
            Many thanks to anyone who can help me.

                    Thank you so much. I just realized my 1.8v conversion board is fried. Waiting for the replacement and I'll upload it.

                        No luck: I wasn’t able to dump the BIOS in any way.

                        I first tried using the 1.8V board, even though the chip is a 25Q256J V EN (not W).
                        Then I tried powering it at 3.3V, but in that case the programmer doesn’t detect it at all.

                        I’m using the CH341A with NeoProgrammer and selecting W25Q256JV, but still no success.

                        Do you have any suggestions, if possible?
                        Thank you very much in advance.
                        Have a great day.

                                Since I didn't have the adapter for this chip, I soldered each pin with a thin wire.
                                I even tried dissoldering it from mobo.
                                Simply not recognized using autodetection and/or setting manually the W25Q256JV chip on neoprogrammer .

                                    Problem with the HP Endpoint Security Controller - HP ProBook 450 G8

                                    Mother: DAX8QAMB8D0 REV D

                                    The device had bootloop issues. I reprogrammed the EC BIOS and the main BIOS, extracted from an HP 440 G8 with the same motherboard, and I was able to start the device. However, every time I turn it on, I get the error 'There is a problem with the HP Endpoint Security Controller in the unit.' I tried disabling several security options in the BIOS, but the error still appears. Additionally, when I attempt to update the BIOS, both BIOS chips get corrupted again....
