I used CH341 2.2 version/ NEO Prog and AS programmer, but non of the programmers has this chip in the listing​

    Thank you for the reply
    I downloaded the app ASProgramme 2.1.2, and as per your Picture attachment,t I can see the chip in the listing, but the software ASProgramme won't recognise it. My CH341(black), so it won't work, but I know that the programmer CH341 does work fine

    Advice from the expert will be much appreciated.
    Are you using an adapter board or a clip.

    Hi, a question...

    Bios for this model (5420) and for this mobo (LA-K491P) is unique for each service tag?

    I tried with several bios of this thread but any is working, that is the reason for the question.

    Thanks

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