Please rebuild. Legion 7 16-ITHG6 NM-D721 R 2.0 i7 11th rtx 3070. I have attached what I believe is original bios 16mb/8mb from board (not sure if previous user tried flashing)

8mb and 16mb bios from this thread me is already initialized and not working. No display (lcd backlight turns on quickly on first boot if cmos reset). RGB turns on, fans spin. Reboots around every 30 seconds.

I flashed the rebuilt files and the symptom is unchanged: powers on, RGB works, black screen, restarts every 21–22 seconds. After CMOS clear, the LCD backlight flashes only once very quickly on first boot. I can send video if requested.

Can you rebuild using my original 64mOLD.bin as the 8MB descriptor/ME base? My physical PCH is SRKMA / HM570 B1 and my original 8MB shows CSE ME 15.0.35.1951, TGP/EBG-H B, ARB 4, VCN 26. The returned 8m.bin shows older CSE ME 15.0.30.x / TGP/EBG-H A.

The original 8MB (64m old.bin) should be the correct board ME/descriptor.
