Thank you, but that thread is for DAG3KQMBAE REV:E which is the Intel version. My board is DAG3KRMBCD0 REV: D AMD Ryzen 9. Is that file still compatible?

I've already unsoldered the chip and flashed a bios i found online for free, but still same error, if the intel version of the bios is compatible with mine ill just try that one...

Done, I've attached the original corrupted backup....

Board: DAG3KRMBCD0 REV: D
Model: HP Omen 16-c0950nz
Serial: 5CD151F4QW
CPU: AMD Ryzen 9 5900HX
GPU: Nvidia RTX 3070
BIOS chip: GigaDevice GD25LQ128C 1.8V 16MB
Problem: While using Ubuntu with a light program running, the screen suddenly went black. Fan speed was normal, keyboard LEDs were still on. After reboot, no video on internal or external display, not even at BIOS level.

What I tried:
Tested with single RAM sticks in both slots
Tried external monitor via HDMI
Performed IPA wash of the motherboard
Flashed official HP...
