Unable to sign Thinkpad X270 Bios

[zerphan]

I have read the bios off my Thinkpad X270 and modded it to remove whitelists.
In order to flash it I need to sign it. I am using thrimbor/thinkpad-uefi-sign but keep getting the error 
ERROR: Could not find public key modulus in firmware file!
I've attached a link to my patched bios and any advice would be greatly appreciated.

In order to flash it I need to sign it.

"thrimbor/thinkpad-uefi-sign" repository doesn't provide any possibility related to flashing. It's oriented to work on TCPABIOS keys, which affect the BIOS when it is already flashed.
Your BIOS does not have that protection, so the script reports the error.

Please tell me, after the modification, will the laptop make a buzzer when loading?
