Fix Call of Duty / Warzone TPM attestation on ASUS TUF Gaming A15 FA506IV when fTPM version 3.42.0.5 fails AMD PA-420 checks.
| Problem | Warzone blocks FA506IV even with TPM 2.0 + Secure Boot enabled |
| Cause | AMD fTPM 3.42.0.5 (3.*.0.* bad pattern) on BIOS FA506IV.320 |
| Fix (v1.3) | Replace full fTPM trustlet + EZ Flash USB (Windows /fw cannot flash patched ROM) |
| Download | Releases (latest) |
| Website | hesamsamani.github.io/fa506iv-ftpm-fix |
v1.0.0–v1.2 withdrawn for flashing: Windows
/fwESRT update fails (0xC0000001) becauseoem96.catonly signs the stock ROM. Use v1.3 GUI + EZ Flash USB.
