Asus UM431DA - problems after having flashed a new bios dump

I have problem with UM431DA bios dump - attached - created from update BIOS from Asus site, my oryginal DUMP has been damaged and i flash a new one. On the new dump i dont have serial numer and my keyboard backlight not working. Can I write SN and repair backlight? I don’t have original dump.

@gesnat : Welcome to the Win-RAID Forum!
Since the requested BIOS modding procedure is too difficult for me and our BIOS modding Guru is absent since several months, I recommend to buy a new BIOS chip for your ASUS notebook.
Good luck!
