A1502 820-3437 need BIOS

[oustou]

Hello,

I am working on a A1502 820-3437 that was water damaged.
I need a clean bios please. My original bios is attached here.
SN : C02N61KGG3QH
I tried to clean the MERegion but each time it didnt work. Sometime the bios cleaned works for the first power-on with chime but after a restart it does not chime with no folder on screen. Sometimes the fan spins normally, and sometimes it spins and stops in a loop.

Question :
-what does it mean the mouse activity ?
-Is there a manipulation to do before supplying the board ?
-Why, with my modified bios the first starting chimes and nothing on the next ?

Thanks a lot
