Universal Multi-Gen GPU Unlock v1.6.1 (Hotfix: Factory Selector Tolerance & PowerShell Fix)

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 v1.6.1

  • VBIOS Factory Selector Tolerance (Resolves #4):

    • Expanded cold-boot SS1 selector verification (profile.c and unlock_610.c) to accept all un-unlocked states (SS1 <= 7, including SS1 = 0x0).
    • Resolves pre-flight refusal (Selectors invalid: SS0=0x25527121, SS1=0x0 (expected SS1==1, 3 or 7)) on RTX 4090 models with factory VBIOS revisions that initialize the secondary selector index to zero.
    • Special thanks to @gabrielfougeron for the detailed log file!
  • PowerShell Variable Scope Fix (Resolves #3):

    • Corrected variable interpolation in Setup-AdaUnlock.ps1 during manual USB drive selection (":"), preventing an InvalidVariableReferenceWithDrive syntax error on Windows 11 PowerShell.
    • Special thanks to @gabrielfougeron for identifying the issue!
