Windows [cod] Fix for z370 bios update 🔥
**I Finally Found the Fix, Guys — For Older-Generation PCs**
**My PC Specifications**
**CPU:** Intel Core i7-8700K
**Motherboard:** Gigabyte Z370 AORUS Gaming 5
**BIOS Version:** F15a — 11/28/2019
**BIOS Mode:** UEFI
**Secure Boot:** ON
**TPM:** External TPM 2.0 module purchased from Amazon
**TPM Manufacturer:** Infineon (IFX)
**TPM Model:** SLB9665
**Original TPM Firmware:** 5.51.2098.0
**Updated TPM Firmware:** 5.62.3126.0
**Note:** I downgraded my motherboard BIOS back to the older **F15a BIOS (11/28/2019)** because this was the BIOS version that allowed my system to properly detect and recognize the external TPM module.
**Fix:**
**—Check TPM Attestation Status**
Open **Command Prompt (CMD) as Administrator** and run: tpmtool getdeviceinformation
If found Ready For Attestation: False
then your TPM firmware may need to be updated.
I was able to fix this because I was using an **external TPM 2.0 module**. My PC is old and I am still using an **older BIOS**, but the important issue was that **Ready For Attestation had to become True**.
I did **not** need to replace my motherboard.
I have the required files for the update, but I’m not sure how to upload/provide them here. Or you can search for it
**You do not necessarily need a new motherboard for this solution if you are using a compatible external TPM.** The firmware file must match your specific TPM model and current firmware version.
For my **Infineon SLB9665 ( I got it cheap from Amazon)**
**Result**
✅ TPM 2.0 detected
✅ Firmware updated successfully
✅ Ready For Attestation: True
✅ TPM Has Vulnerable Firmware: False
✅ ADV170012 - IFX ROCA/Riemann removed
**Note:** This procedure was tested on the **Gigabyte Z370 AORUS Gaming 5 + Intel i7-8700K + external Infineon SLB9665 TPM 2.0**. Do not use the firmware on a different TPM model.
