Help to swap bios please

One month ago I bricked my Asus S550CM notebook upgrading bios but after an hard work I found a full dump from another motherboard. Now the pc work but bios isn’t exactly the same, so I tried to flash original bios from Asus website (S550CMAS202.zip) but Afudos give me error “3 - Error: ROM file size does not match existing BIOS size”. Anybody is able the swap bios from this DUMP with S550CMAS202 from the other link?

@Tony2k :

If you enter "ROM file size does not match existing BIOS size" into the "Search…" box of this Forum, you will get some hints. Maybe this will help you to find a solution.

Hello Fernando! Believe me, I did lots of research on the forum + Google but have not found the solution!
