A few things:
1.) Could I get that copy of your new BIOS dump after flashing? I want to ensure it flashed properly, even though it said it did (in theory, it shouldn't have been able to flash at all if either BIOS flash prevention setting was set to enabled).
2.) Is there a UEFI Variable named "Setup"? If so, is it large enough so that it contains offset 0x1206 (1206)? In theory, both FPRR (0x1206) and BIOS Lock (0xBC4) should be in the same UEFI Variable - the one that corresponds to PCH-IO Configuration under the Chipset Menu. We just need to locate the right variable.
3.) For our reference...
BIOS Lock: Chipset -> PCH-IO Configuration -> Security Configuration -> BIOS Lock
Flash Protection Range Registers: Chipset -> PCH-IO Configuration -> FPRR
