    EC dump request – Dell Latitude 5420, GDF40 LA-K491P Rev 3.0, MEC5107-LJ

    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!

      W25Q80 (UT7) holds most likely thunderbolt firmware, mec has its own internal firmware.

          It is the thunderbolt firmware. One way to check is to search for the words ARC PARM
