WARNING: This may cause your system not to start. Use at your own risk.

 

The below procedure allows you to flash an older BIOS on motherboards without USB BIOS Flashback feature. The lack of this feature means there's no simple way to recover if things go wrong.

 

Software required

 

• UEFITool v0.21.5 Thread Mega
  
• Intel Flash Programming Tool for ME 11.0 Hwbot (note that you need to unzip using a software which supports RAR5)
  

 

Prepare the BIOS file for use with FPT

 

1. Get the BIOS for your motherboard in CAP format (in this case MAXIMUS-VIII-IMPACT-ASUS-0019.CAP)
   
2. Open the CAP file in UEFITool
    
   
    
    
   
3. Export to ROM (MAXIMUS-VIII-IMPACT-ASUS-0019.ROM)
    
   
    
   
4. 
   

 

 

Using FPT to flash the BIOS on your system

 

1. Open a command prompt with Administrator rights and navigate to your FPT directory
   
2. Flash the BIOS by using the command fpt -bios -f BIOS_FILE.ROM
    
   
   

 

Note: There are DOS/EFI/Win32/Win64 versions, this guide uses the Win64 version.

I can overclock my COre i7-6400 T (ES) on H110\B150 ASUS motherboard, (e.g. ASUS B150 PRO GAMING with 10 phases)?

Thank you very much. I try updating BIOS to 2202 on ASUS Z170-A and it can't flash back !!! Your guide work well and I can flash to my non-K OC BIOS again.

Where can I download fptw64?

copy the files in \Intel ME System Tools v11.0 r1\Intel ME System Tools v11.0 r1\Flash Programming Tool\WINDOWS64 to the location of the ROM file and then run the cmd commands

I get the same error, the ftp command doesn't exist. I copied the files onto the same folder that my .rom files are located and I still get the message.

D:\Flash Programming Tool\WINDOWS64>FPTW64 -bios Z170I-PRO-GAMING-ASUS-0403.ROM

Hi Elmor! I tried your method and got "failed to disable write protection for BIOS space"

Mb ASUS z170-AR, bios 3401. I don`t have Flashback feature. Is there a way around it?

Thanks.

Tried to downgrade 3016 to older bios successfully using AFUWIN. It works for me using this command:

C:\>afuwinx64 filename.rom /GAN
