Failed Attestation Status despite everything passing – TPM, Secure Boot, AIK, COD Broker all OK (9800X3D / MSI X870E) HELPPP!!!!!

Hey everyone,

I’ve been trying to solve this for hours and I’m running out of things to check, so I’m hoping someone here has dealt with the same situation.

I’ll give the full context because I don’t want to hide anything.

A while ago I got banned from COD after using an Unlock All tool. I know that was stupid and I’m not trying to defend using it. At this point I just want to play COD normally again without cheats, unlock tools or anything like that.

Since then I rebuilt the PC software side, reinstalled Windows, and changed some hardware/firmware identifiers while troubleshooting. After getting everything running again, COD launches perfectly fine, but when I try to enter certain playlists I get:

“You are under Failed Attestation Status. This playlist is currently unavailable.”

The weird part is that basically every attestation test I can find says the PC is fine.

My system:

* Ryzen 7 9800X3D
* MSI MPG X870E EDGE TI WIFI
* BIOS 1.A20
* Windows 10 Pro 22H2
* Build 19045.7663
* UEFI boot
* Secure Boot enabled
* Physical/discrete TPM 2.0 installed
* Infineon SLB9670
* TPM firmware 7.63.3353.0
* COD tested on both Battle.net and Steam

I originally used AMD fTPM, but I later installed a discrete Infineon TPM and selected it in the BIOS.

Windows correctly detects the new TPM:

Manufacturer: IFX
Manufacturer Version: 7.63.3353.0
Specification Version: 2.0
Status: The TPM is ready for use

tpmtool getdeviceinformation gives:

TPM Present: True
TPM Version: 2.0
TPM Manufacturer: Infineon

Is Initialized: True
Ready For Storage: True
Ready For Attestation: True
Is Capable For Attestation: True
Clear Needed To Recover: False
TPM Has Vulnerable Firmware: False
Is Locked Out: False

Get-Tpm gives:

TpmReady: True
TpmEnabled: True
TpmActivated: True
TpmOwned: True

ManufacturerIdTxt: IFX
ManufacturerVersion: 7.63.3353.0
AutoProvisioning: Enabled
LockedOut: False

The Endorsement Key certificate is also present and valid.

It identifies as:

TPMModel=SLB 9670 TPM2.0
TPMManufacturer=IFX

and the EK certificate is issued by:

Infineon OPTIGA(TM) RSA Manufacturing CA 035

Secure Boot is definitely enabled:

Confirm-SecureBootUEFI

returns:

True

msinfo32 shows:

BIOS Mode: UEFI
Secure Boot State: On

One weird thing is:

PCR7 Configuration: Binding Not Possible

although I understand that this does not necessarily mean attestation itself is broken.

I also restored the Secure Boot factory keys in the MSI BIOS:

Security → Secure Boot → Custom → Key Management → Restore Factory Keys

Then changed Secure Boot back to Standard.

Secure Boot still reports True afterwards.

The official Call of Duty Secure Attestation Wizard 1.1.3 says:

System compliant

TPM 2.0 passes.

Secure Boot passes.

There is no “Generate Key” button because the Wizard does not detect an Authorization Key failure.

I checked the COD Broker Service as well.

It exists:

COD.Broker.Service

and while COD is running:

Status: Running
StartType: Automatic

(I tested both Manual and Automatic.)

The broker log says:

Enroll AIK result 0.

I went further and manually tested Microsoft AIK enrollment:

certreq.exe -EnrollAIK -machine -config ""

This succeeds completely.

Result:

PkiStatus(0): SCEPDispositionSuccess
EnrollStatus(1): Enrolled
The operation completed successfully. 0x0
Submit(ChallengeAnswer): OK
HTTP/1.1 200 OK

Microsoft actually issues a new AIK certificate successfully.

I checked the Microsoft Platform Crypto Provider too:

certutil.exe -csp "Microsoft Platform Crypto Provider" -key

and I have:

ActivisionAIK
TestAIK-...
TestAIK-...

So ActivisionAIK exists as well.

I also checked Windows logs immediately after reproducing the Failed Attestation error.

Code Integrity only shows:

Code Integrity will enable WHQL driver enforcement for this boot session.

TPM events show:

The TPM was successfully provisioned and is now ready for use.
The TBS device identifier has been generated.

There are no TPM, TBS, Secure Boot or Code Integrity errors at the time COD rejects the playlist.

Measured Boot logs are also being created normally under:

C:\Windows\Logs\MeasuredBoot

The newest logs are generated after every reboot.

Things I have already tried:

* TPM 2.0 enabled
* switched from AMD fTPM to discrete TPM
* Secure Boot enabled
* CSM/legacy boot not being used
* UEFI boot
* restored Secure Boot factory keys
* switched Secure Boot Custom → Standard afterwards
* fully updated Windows
* latest relevant drivers
* COD Secure Attestation Wizard
* COD Broker Service running
* Broker set to Manual
* Broker set to Automatic
* Scan and Repair
* reboot/cold boot
* manual AIK enrollment
* tested BattleNet
* installed the game again on Steam and tested there

Steam gives the exact same Failed Attestation Status, so it doesn't seem to be a Battle.net-specific problem.

The thing that confuses me most is that the actual Microsoft AIK infrastructure accepts this TPM:

IFX-KeyId-...
microsoftaik.azure.net
HTTP 200 OK
Enrolled

and even COD's own Broker reports:

Enroll AIK result 0

yet the game still considers the machine to have failed attestation.

I have already submitted the Activision TPM Diagnostic Report for systems that pass the Wizard but still fail in-game.

I’m not trying to bypass the attestation checks. I’m trying to figure out why the machine passes every official test but the game still rejects it.

Has anyone had this exact combination?

Especially interested if you have:

* Ryzen 7000/9000
* MSI X870/X870E
* an Infineon SLB9670 discrete TPM
* Wizard = System Compliant
* Ready For Attestation = True
* AIK enrollment = HTTP 200
* but COD still gives Failed Att

Are you saying you cheated, got caught and banned. You are using hacked/custom firmware and wondering why it's not working... Or am I misunderstanding?

I did get banned in the past for using an Unlock All tool, yes. I’m not denying that.

But no, I’m not using hacked/custom firmware. The motherboard is on an official MSI BIOS, Secure Boot is enabled, Windows is fully updated, and the TPM is a normal Infineon SLB9670 discrete TPM.

I did change some hardware identifiers after the ban, but the issue I’m asking about here is why COD reports Failed Attestation when its own wizard says System Compliant, Microsoft AIK enrollment succeeds with HTTP 200, and the COD Broker reports successful AIK enrollment.

I’m trying to understand which attestation check is still failing despite all of that.

what did you change when you got banned? and did you change hardware identifiers through third party or by switching parts?

try reinstalling windows 11

Do this and solve the issue. I have that cpu. Do a windows c: formst win11 latest also works
Use this manual on the post.

The hardware itself wasn’t replaced. Some identifiers were changed through third-party software/tools. I’m trying to figure out whether the Failed Attestation is caused by the Windows/TPM provisioning state rather than the identifiers themselves, since Microsoft’s AIK enrollment and the official COD Wizard both pass.
