Wow thanks for all the help and suggestions! I will look into swapping the BIOS chips but at this point I am probably just going to swap out the CPU's as I want to check my gear to make sure that it all works but thank you for all the help!

 
No problem..Just offering up a 'trick' to flashing for folks between a rock and a hard place.

That would be great and one less hassle on the customer and the mfger has to deal with.

 
Indeed it would be..No muss, no fuss..Works for me..Takes about 45 seconds here.

I just purchased 5 I7 6800k’s and 5 X99**** K motherboards, all had 2.01 BIOS.
 
C indicates a CPU fault I just went through a similar issue.
 
Two of the I7’s were DOA one caused a “C” error code the other wouldn’t post at all.
 
I may have received two bad CPUs, but they weren’t from the same batch and they were the first two I tried, out of caution we are RMAing the suspected RAM, Motherboard and the two DOA I7’S.
  
2 of the machines have Ballistix Elite BLE4K4G4D26AFEA (including the one that failed)
3 of the machines have Ballistix Tactical BLT4K4G4D26AFTA
All of the machines have EVGA 1060 GTX 6gb, Corsair 760 T cases and Corsair RM 750I PSUs.
