Flash back original BIOS to Asus x555LN

[dough29]

Hello !

A friend of mine gave me an Asus x555LN laptop that failed on updating the bios.

The computer wouldn't even start.

I flashed a dump from the Internet with a CH341a interface, it is a BIOS from a x555LD and that worked : I can boot Windows 

Now I'd like to flash back a x555LN BIOS so the computer gets it's original working state.

I've seen downloadable file from Asus Support doesn't looks like the file I can write with my CH341a interface.

Can someone help ?

Attached files :
- dump from when I got the computer
- dump "working" for now (x555LD in place of x555LN)
- file from Asus Support (X555LNAS.313)

Thank you for reading !
