Solution
yea all the motherboard i seen never let you downgrade the BIOS. it sucks but now you'll have to get a skylake CPU to get your computer to boot to update the BIOS. intel celeron and pentium CPU's are the cheapest you can get

my friend has an i7 6700k can i use it to boot my pc to the bios?
 
Most reputable brands of motherboards include some kind of bios update utility, and they also have the various bios choices arranged by version and date. I'd be interested in hearing your story about how you did this 'by mistake'. You really don't want to mess with a bios unless you know what you're doing and why you're doing it.
