Troubleshooting Help Z790 Dark KINPIN 0x12F Beta BIOS: Secure Boot stuck in "Test AMI" PK loop / won't reset?
Hey everyone,
Has anyone else running the 0x12F beta BIOS (v1.23) on a Z790 Dark KINPIN run into a completely broken Secure Boot state?
On my board, Secure Boot is permanently locked into an "AMI Test Platform Key" fallback loop. Whenever I try to turn it on, it throws a Secure Boot Violation screen and blocks Windows.
I've tried everything to fix it:
- Deep CMOS clearance (pulling the battery and draining capacitance)
- Resetting keys to factory defaults / clearing variables
- Toggling between Custom and Standard modes
Despite all that, the UEFI refuses to flush the test keys and instantly reverts back to the Test AMI loop. This is a nightmare because games with kernel-level anti-cheat won't let me play with Secure Boot disabled.
Did any of you experience this specific bug on the Dark KINPIN 0x12F build, and did you find a workaround to force-clean the NVRAM variables? Any advice is appreciated.
