@turner As Kookieezz suggested, attempt to make a backup from bootable USB using FPT from either MS-DOS or a UEFI shell.
You should download FPT v9.1 which can be found in ME System Tools v9.1 r7.rar from this thread:
Intel (Converged Security) Management Engine: Drivers, Firmware and Tools (2-15)
The archive contains versions for Windows, MS-DOS and UEFI shell.
