1. Download Intel CSME System Tools v11 and unpack it.
2. Go to Intel CSME System Tools v11 r34\Flash Programming Tool\WIN64 and run in command line with administrative rights:
fptw64 -a 0x2B9800 -l 0x19400 -d 806EA.bin
Make a screenshot of result.
3. Give me file 806EA.bin in zip

Now you can try to flash back it.
fptw64 -a 0x2B9800 -l 0x19400 -f 806EA.bin
Make a screenshot of result.

Current BIOS has activated write protection.
Has it Advanced page?

1. Take USB stick and format to FAT32
2. Create directory structure EFI\Boot
3. Download and unzip bootx64.7z
4. Put BOOTX64.EFI into Boot directory
5. Boot from USB stick
6. Run in command line:
setup_var 0x17
Make a photo of the screen with result.
