hi sir
I have a NM-B452 board that hangs at the customer in the middle of a BIOS update
And the customer turned off the laptop by force
I tried to burn the bios and the EC from the beginning of the post
But the laptop keeps turning off and on
and does not display an image on the screen

Is it possible to repair the original files which I have attached?
