Hello,
I'm requesting a full BIOS dump (including EC firmware) for an HP OMEN 17-an012nf laptop.
Details:
Model : HP OMEN 17-an012nf
Motherboard Part Number : DAG3BAMBAF0 REV : F
Serial Number (S/N) : 5CD7280D51
BIOS chip : Winbond W25Q64VSIQ
Programmer : EZP2023+
Issue : The motherboard is not powering on. Only the 5V rail is present. The 3.3V rail is missing because EN1 on the SY8286B remains stuck at 0V. This signal is driven directly by the EC/SIO. I replaced the 3.3V regulator and confirmed it's working.
I already tried reflashing the original dumped BIOS from this board, but the issue persists. It seems to be related to corrupted EC firmware or bad logic in the BIOS region.
What I'm looking for:
A clean, working SPI dump for this board that includes both the BIOS and embedded controller (EC) firmware. Preferably a known good working version (e.g., BIOS F.20/F.22), compatible with this board revision.
Thank you in advance for your support!
Best regards,
