            I'm using the ch341a v1.7 and wson8 probe to flash the bios (since i don't have any micro soldering skills)


            The funny thing about this device (5420) is that if you use any chip other than the 25R the laptop will hang on Dell logo or give different colors (red, blue, green etc)

            I noticed that this chip is fragile and get spoilt easily.
            If you use the 25Q it won't work,at least from experience and that of 2 friends who tried it until they use 25R.

                      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!...
