    Hello, thanks for your quick support, but after the spawned bios, the device does not turn on and flashes the Numlock and Capslock 5 times. Do you have any idea what it can be? I would be grateful for any good tip.

    Good evening, I tried several times, but no effect. I suspect that the dump was already buggy. What other chance do I have to create a new BIOS? Do you already have experience with such actions? thank you

    Tried, the problem persists, so I think the backup is buggy.

    Does not work either. Can the Winbond be broken?
