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

    Notebook HP ProBook 450 G8
    ProdID 2K8L1LT#AC8
    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.
