Re-flashing a soft-bricked Ampere Mobile GPU

Accidentally bricked your Legion’s GPU after flashing a VBIOS? Don’t worry, there’s a way to make your laptop functional again.
A soft-bricked GPU will display a black screen upon boot. To fix this, we will need to boot into safe-mode.

  1. Boot into Safe Mode
  2. Prepare your original VBIOS. If you lost it, you can (in theory) use a VBIOS from site like TechPowerUP
  3. In Safe Mode open CMD as Administrator
  4. Run
     nvflash_patched_ampere -6 *insert original VBIOS name.rom*
