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.
- Boot into Safe Mode
- Download patched NVFlash from this Reddit thread https://www.reddit.com/r/ZephyrusG14/comments/rvqnif/95w_3060_vbios_for_g14/
- Prepare your original VBIOS. If you lost it, you can (in theory) use a VBIOS from site like TechPowerUP
- In Safe Mode open CMD as Administrator
- Run
