Universal Multi-Gen GPU Unlock v1.4 (Hotfix: Device-ID Persistence)

Universal Multi-Gen GPU Unlock v1.4 (Hotfix: Device-ID Persistence)

Universal 1-Click UEFI Pre-Boot Unlocker for NVIDIA RTX 40 Series (Ada Lovelace) and RTX 30 Series (Ampere) graphics cards under Windows 10/11 and WSL2.

🚀 What's New in v1.4

• Hotfix: GPU Device-ID Persistence:

  • Resolved a regression in Discover() where Gu.device_id was zeroed out during UEFI port initialization (causing Device ID 0x0000).
  • Fixes stage=shared-assets status=-19 (-ENODEV) when loading architecture firmware payloads.
  • Device ID is now properly preserved across port re-arm, correctly identifying Ada (0x2684, etc.) and Ampere targets.

• Universal Motherboard Topology Support (from v1.3):

  • Fully supports ASUS ROG/TUF, Gigabyte Aorus, MSI, and ASRock motherboards by accommodating vendor PCIe bridge protocols.
  • Dynamic display endpoint enumeration (supporting up to 8 outputs).

🛡️ Safety & Reversibility Guarantee

• 100% Volatile RAM-Only: Zero EEPROM writes. Powering off or rebooting without the USB drive returns the GPU to 100% factory-stock state.
• UEFI Secure Boot Compatible: Authenticode-signed with custom certificate (AdaUnlock_SecureBoot.cer).
• Official NVIDIA Driver: Works seamlessly with standard, unmodified Windows Game Ready & Studio drivers (nvlddmkm.sys).
