Bios help

Hello! Welcome to TechSpot!

In most cases it's the same way it was flash updated but only if
original bios was saved. Otherwise you'd have to find the version you want to rollback to from MoBo mfg. site.
 
More info please - mainboard make and model might be helpful, though be advised, sometimes you just can't do it, depending on why you'd need to.
