Call of Duty Failed Attestation Status Fix

If Call of Duty is showing a security, TPM, Secure Boot or Failed Attestation message, this guide explains what it means and what you may need to check.

What does this error mean?

Some newer Call of Duty security checks require your PC to support TPM 2.0, Secure Boot and a valid security attestation status. In simple terms, the game is checking that your PC security features are switched on and trusted.

If you see a message such as Failed Attestation Status, BIOS firmware update required, or Your PC does not meet security requirements for Call of Duty, it does not always mean your PC is faulty.

In many cases, TPM and Secure Boot may already be enabled, but your motherboard BIOS may need updating so the TPM firmware can pass the latest attestation checks.

Step 1: Run the Call of Duty Secure Attestation Wizard

Activision provides a Secure Attestation Wizard which can help identify what your system is failing on. Download and run the tool below, then follow the result shown on screen.

Download COD Secure Attestation Wizard
Only download security tools from official sources. Do not download random TPM or Secure Boot fix tools from forums, file sharing sites or unknown links.

Step 2: Check TPM and Secure Boot in Windows

Check Secure Boot

  1. Press the Windows Key and type System Information.
  2. Open System Information.
  3. Look for BIOS Mode. This should normally say UEFI.
  4. Look for Secure Boot State. This should normally say On.

Check TPM

  1. Press Windows Key + R.
  2. Type tpm.msc and press Enter.
  3. Check that the TPM status says The TPM is ready for use.
  4. Check that the Specification Version is 2.0.

If TPM is enabled and Secure Boot is on, but Call of Duty still fails attestation, the next likely step is a motherboard BIOS update.

Step 3: Identify your motherboard

Before updating the BIOS, you must know your exact motherboard model. Do not guess.

  1. Press the Windows Key and type System Information.
  2. Open System Information.
  3. Look for BaseBoard Manufacturer.
  4. Look for BaseBoard Product.
  5. Look for BIOS Version/Date.

You can also check the motherboard box, invoice, order details or the model printed directly on the motherboard.

Important: Never install a BIOS file for a similar looking motherboard. The BIOS must match your exact motherboard model and revision.

Step 4: Update your motherboard BIOS

A BIOS update can fix compatibility, security and TPM firmware issues, but it must be done carefully. The general process is:

  1. Find your exact motherboard model.
  2. Go to the official motherboard manufacturer support page.
  3. Download the latest BIOS for your exact model.
  4. Extract the downloaded ZIP file.
  5. Copy the BIOS file to a USB stick, usually formatted as FAT32.
  6. Restart the PC and enter the BIOS.
  7. Use the motherboard’s built-in BIOS update tool.
  8. Do not turn off the PC during the update.
  9. After the update, re-check TPM, Secure Boot and UEFI settings.
BIOS updates carry risk. If the wrong BIOS is installed, or if power is lost during the update, the motherboard may stop working. If you are not confident, ask for help before continuing.

Common motherboard BIOS update tools

ASUS

Usually uses ASUS EZ Flash or USB BIOS FlashBack on supported boards.

ASUS Support
MSI

Usually uses M-FLASH from inside the BIOS.

MSI Support
Gigabyte

Usually uses Q-Flash or Q-Flash Plus on supported boards.

Gigabyte Support
ASRock

Usually uses Instant Flash from inside the BIOS.

ASRock Support

The exact tool name and steps can vary depending on the motherboard model. Always follow the instructions from your motherboard manufacturer.

Before updating BIOS, check BitLocker or Device Encryption

Some PCs use BitLocker or Windows Device Encryption. A BIOS update or TPM change can sometimes trigger a recovery key prompt.

  1. Open Windows Settings.
  2. Search for Device Encryption or BitLocker.
  3. If encryption is enabled, make sure you have your recovery key saved before updating BIOS.
  4. Do not clear the TPM unless you fully understand the consequences.
Do not clear or reset the TPM unless you have checked encryption first. Clearing TPM can cause recovery key prompts or access issues on encrypted systems.

What if there is no newer BIOS?

If your motherboard is already on the latest BIOS and Call of Duty still reports Failed Attestation Status, the motherboard manufacturer may not yet have released a BIOS containing the required TPM firmware update.

In that situation, you may need to contact the motherboard manufacturer and ask whether they are releasing a BIOS update to fix TPM attestation failure. On some systems, a compatible physical TPM module may be an option, but only if the motherboard supports the correct module type.

If no BIOS update or TPM module option is available, the only reliable fix may be changing to a motherboard with better firmware support.
