TPM_E_WRONGPCRVAL

TPM_E_WRONGPCRVAL means that the PCR value named by a TPM 1.2 operation does not match the PCR value currently held by the TPM. The PCR selection and policy data are interpretable; the measured state simply differs from what the protected object expects.

This is a crucial distinction from TPM_E_INVALID_PCR_INFO. The latter concerns invalid PCR information. TPM_E_WRONGPCRVAL is a real policy mismatch and often follows a change in boot components, firmware, measured configuration, or the event sequence used to extend PCRs.

Evidence before remediation

Collect the PCR selection, expected digest, current PCR values, and the relevant measurement or event-log evidence.
Identify the specific state transition that changed the measurement: firmware, boot manager, boot configuration, operating-system component, or policy baseline.
Use the approved recovery or resealing workflow. Do not edit a sealed-data blob or force PCR values; PCRs are measurement registers controlled by TPM command semantics.
