there's a bios backup file in c:\bios folder, you can use it but it's possible that you break the main-board.

if you want to use it, rename the bios.bak file to bios.wph, re-flash it.

hey indest,

why would you want to downgrade ? is there any issue with the current bios that you're using?

Do note that Yigit's method of re-flashing can work but it is true what he says and your unit may brick.
