Hello everyone,

I need the EC firmware dump for Dell Latitude 5420, motherboard GDF40 LA-K491P Rev 3.0 (A02).

The embedded controller is MEC5107-LJ (UE1).

The EC flash chip is W25Q80DV, 8Mbit (1MB).

I already have the 32MB BIOS dump (W25Q256JV), but my system is still not powering on — just amber blink. I suspect the EC firmware is missing or corrupted.

If anyone has this board and can share their EC dump from the 25Q80DV, I’d be very grateful.

Thank you in advance!...
